1. Tin Bronze Metallurgy in Transformation: Analytical Investigation of
Crucible Fragments from Tell Judaidah, Amuq (Turkey) Dating to circa
3000-2900 BC

***The Oriental Institute, The University of Chicago, 1155 E 58th Street, Chicago, IL 60637
Between 1932 and 1938 the Oriental Institute of the University of Chicago excavated several sites in the Amuq
valley in the Hatay province, Turkey. The sites have held great interest for early metals researchers ever since
the discovery of the six Amuq G polymetallic figurines and a crucible with a tin rich copper encrustation from
Tell al-Judaidah, which are to date, the oldest tin bronzes in the Near East. Several copper artifacts from Phase
G (c. 3200-2900 BC) contain appreciable tin contents as well. Indications exist of copper utilized since the
earliest period if incipient agriculture, the Neolithic, Phase A. Important hints to the presence of an innovative
metal technology exist from the subsequent Chalcolithic period: alloying copper first with arsenic in Phase F
levels (c. 4500-3500 BC), and nickel rich alloys and tin in Phase G.
In the study we have concentrated our work on the examination of the residue adhering to the inner surface of
the Phase G crucible. Electron probe X-ray microanalysis (EPMA) and secondary ion mass spectrometry
(SIMS) were used to obtain detailed compositional analyses of the material. The data were compared with
products obtained by experimental simulation of copper and tin smelting under different conditions. The goal of
the latter essentially existed in assisting the interpretation of analyses of excavated metal industry products from
the Amuq. Results were able to demonstrate that the Amuq residue is a result from alloying copper and tin. The
latter implies that the metal alloy preparation was actually done at the site.
2. Multidisciplinary study of the human impact at the Eini site, Lubana
Plain, Eastern Latvia
Lacis Agris* - Loze Ilze** - Kalnina Laimdota***
*Geological Survey of Latvia
**University of Latvia, Institute of History of Latvia
***University of Latvia, Faculty of Geographical and Earth Sciences
The Eini site is located in Lubana Plain (Eastern Latvia) which is unique by its direct reflections of the
Holocene events and rich in archaeological finds and discoveries with 27 Stone Age settlements dated by 80
14
C dates. The aim was to collect and integrate data from geological, geophysical, topographical investigations
of the site, palynological analyses of two cores - Eini Lake (int. 0.0-6.3 m, 170 samples) and Eini site (int. 0.01.57 m, 87 samples), radiocarbon dating and archaeological and archaeozoological studies in order to attempt a
coherent reconstruction of changes in the landscape and cultural history in Eini site.
New palynological data, a set of geological and archaeological studies in the area demonstrates in detail the
Holocene vegetation development and the increase in human impact. The studies of the sediments from both
cores (Eini Lake and Eini site) provide comprehensive information of the vegetation history and environment
development and fixed a limited human impact (the presence of anthropogenic indicators - Plantago lanceolata,
Plantago major/media, Rumex acetosa/acetosella, Polygonum aviculare, Brassicaceae) on the local
environmental conditions during the Atlantic time (AT2) Neolithic. The palynological indications suggest a
fluctuating character of human activities. The first few Cereales are found at the Middle Atlantic, but the real
start of the introduction of Cereales is likely to have happened at Subboreal (int. 0.9-0.6 m Eini site section),
Late Neolithic, when hunting and fishing dominated, but early farming had a secondary subsistence strategy.
Human impact on the environment is traceable in both the investigated diagrams: a relatively short-term
minimum of Corylus is accompanied by the decline of Ulmus and Tilia and the increase in the meadow and
ruderate community graphs along with the appearance of Cereales.
This kind of research is necessary to carry out in all settlements in this region.

3. A detailed study of the archaeological site of Kitros (N. Greece) by
combined magnetic and spectrometry methods

***Nuclear Research Center "Demokritos", Athens, Greece.
The archaeological site "Louloudia - Kitros" was created in 479 A.D. when the Bishop of Pydna moved there
after the Goths' occupation of his former seat. The complex (80x90 meters) consisted of a Basilica, the Bishop's
residence and installations for the production of wine and olive oil. The settlement was destroyed by an
earthquake around the middle 6th century A.D. and later on was used as the locus of workshop activity.
Soil samples were collected from several trenches within the archaeological site, as well as radial traverses
around kilns, which were used for glass production. Finally, samples were collected from a long traverse,
starting from the middle of the archaeological site and extending outside of the site, in order to identify the
limits of the archaeological settlement. Magnetic susceptibility measurements have shown significant variations
with depth. Spectrometry analysis (ESR) of these samples has shown a large amount of iron oxides and, in
some cases, important contents of manganese. In selected samples, Mössbauer spectrometry analysis was
applied to define the percentage content in iron oxides. IRM measurements are also in progress in an effort to
refine the distinction of the samples originating from different areas of activity.
The above experiments were successful in identifying the different occupation levels and the boundaries of the
archaeological site. High values of magnetic susceptibility and iron oxide content were well correlated with the
periods of intense human activity. Around the kilns, the mean values of the magnetic susceptibility indicated
the effect of the fire mechanism in the surrounding area and also gave some first evidence concerning the use of
the kilns. Comparison of the magnetic and chemical properties of the anthropogenic soils suggests that their
enhancement may be used as an index for locating areas and features of archaeological interest.
Additionally, archaeomagnetic data have been obtained from a pottery and a glass kiln of the site. The
magnetic components (D = 355o, I = 62o, a = 3.6 and D = 356o, I =51o, a = 2.3) were correlated to the reference
curves compiled for Greece (Evans, 1996) and showed a satisfactory consistence for the declination but some
deviation for the inclination of the recorded magnetic field values.

The study of Egyptian blue and green frit were developed owing to the knowledge of the pigment production
techniques. Most of the published works to treat the characterization and the production of Egyptian blue, while
a few works deal with the green frit. The aim of the present work was to produce and to characterize green frit
from pure chemical components or from Egyptian materials (desert sand, copper objects).
Grounded materials were added of sodium carbonate as flux then mixed with water or Arabic gum to get cakes
and heated in a muffle furnace to various temperatures, obtained products were analyzed by XRD, colourimetric
analysis and examined under mineralogical microscope. Cuprorivaite and tridymite characterize all the samples
of pigments obtained at 850 oC and the appearance blue colour, samples heated to 1050 oC denote the
disappearance of cuprorivaite and the appearance of a green glass (green frit). It seems that wollastonite is
generally present in mixtures containing a lower amount of copper.
15
Archaeometry '98, Budapest
We observe the presence of green glass and tenorite, while cuprorivaite is absent in the samples if pigment
obtained under reducing atmosphere. Results should indicate that 950 oC is a transition temperature where it is
possible to observe different processes, probably due also to kinetic effects.

The aim of the project is to validate a new approach for the tracing of sea-salt routes in ancient material culture.
Salt, on account of its importance for the human organism, has played and continues to play a significant role
in the history of peoples and has on occasions been the pretext for war. In the archaeological record the
production and circulation of salt can be traced from as early as the Neolithic period in Egypt and Europe. In
spite of its importance, due to the fact that alkali salts are easily dissolved and are difficult to trace in ancient
material culture, there is a complete lack of scientific evidence concerning salt contacts. The key-idea is the use
of bromine and its compounds as a tracer of the contact between sea-water and sea-salt with ceramic and lithic
artefacts or structures. Bromine offers a very powerful discriminating criterion between marine and terrestrial
environments. Br occurs in the hydrosphere as soluble bromide salts. Its concentration in sea-water is 65-70
ppm while in earth's crust and streams is only 4.0 and 0.02 ppm, respectively. This is further accentuated
between the marine and terrestrial biosphere (seaweed, sponges, shells, plants etc.) due to the formation of
organic bromine compounds. In the case of salt and salt brines (the main source of Br in modern industrial
practice) it exceeds 2500 ppm.
Experimentally, Br concentration can be measured by using the straightforward and well established X-Ray
Fluorescence (XRF) technique, which through the recent development of high resolution, ambient temperature,
portable instruments lends itself for quick, non-destructive, in situ measurements and surveys with sensitivity of
a few ppm.
In order to validate the technique before it can be reliably applied to address archaeological questions, a series
of preliminary tests and measurements were performed on ceramics and lithic artefacts subjected to contact with
sea water and salt under laboratory conditions. In addition, several ceramic artefacts which are known through
the archaeological record to have served as salt or salt brine containers recovered in inland burial environments
were also analysed. To this effect the Br concentration was measured on fragments of shallow dishes used in the
"briquetage" salt making technique, as well as on "oxygaron" vases (containing vinegar and garum, a fish
sauce) found in Eleftherna, an inland archaeological site in Crete. The measurements will be compared with Br
concentrations in similar artefacts for which the archaeological record excludes salt contact. The results are very
encouraging and confirmed the view that the Br concentration measured as a function of depth from the surface
provides a unique "sea salt" signature.

The first evidences of human settlement in Paraná state are from 10000 years ago. In this region, about 1500
years ago, horticulturalists and ceramists populations appeared, represented by the Tupiguarani and Itararé
groups. The Tupiguarani lived in the valley regions of the Paraná, Ivaí, Tibagi and Iguaçu rivers. The
Tupiguarani sites are related to the Guarani indians ancestors. Tupiguarani populations lived in the region of
the Santa Dalmacia farm at the end of the 16th century or at the beginning of the 17th century and they had
contact with the colonizers, probably
Spanish, due to the observed changes in the pottery production

characteristics. The Santa Dalmacia farm archaeological site was accidentally discovered in 1990 and belongs
to Cambé city municipality, north of Paraná state, south of Brazil.
The objectives of this work are: to analyse the ceramic paste composition, as well as the superficial layer of the
ceramic fragments, in order to get information about the pigment composition of the plastic decoration;
comparison of the ceramic pastes composition between typical Tupiguarani fragments and the fragments that
present characteristics of contact with the European colonizers.
The analytical technique employed was the energy dispersive X-ray fluorescence (EDXRF), in two different
experimental set-ups. The first set of measurements was carried at Sassari University with two X-ray tubes (30
kV and 0.1 mA; 80 kV and 5 mA), secondary targets of silver and gadolinium, and an Amptek Si-PIN
detector, thermoelectrically cooled, having an 70 mm Be entrance window and 300 mm thickness. The second
one was carried at Sao Paulo University using a 238Pu radioactive source and a Si(Li) detector with a Be
window. X-ray spectra were processed and quantified (at Sassari and Londrina) by using the AXIL program.
The ceramic pastes can be characterized by a low Ca content, and a systematic presence of relatively high
concentrations of Ti. Fe is also always present at high levels, and Ni, Cu and in some cases Zn at level of
traces; Rb, Sr, Y and Zr are also present, and Ba in all samples at low concentration.
The black pigment in the pottery plastic decoration is due to the presence of Mn, the red pigment is due to the
presence of Fe, while the white pigment is characterized by the presence of Ba.
Other qualitative and quantitative results were obtained for each kind of ceramic fragment group and will be
also presented.

This paper aims to give some results coming from an archaeometallurgical research project recently started,
studying two technological aspects of bronze objects from Late Bronze Age to "Gallo-Roman" times. The first
concerns the forming processes, the second is related to decoration techniques. The contribution focuses on the
questions related to the manufacturing techniques and tools used for decoration. Decoration may have been
executed by plastic deformation (tracing, repoussé, punching, stamping) or by cutting off metal (engraving,
chiselling, spinning, abrasives). For understanding necessities and cultural choice as well as technological
changes, it is important to find characteristic features for distinguishing the two techniques. Special interest lies
on the execution of incised ornaments on sheet as well as on massive bronze objects, with incisions having
mostly a linear traces of geometric design.
The Late Bronze Age hoards of Burgundy are rich in sets of exceptional quality. Some examples will be
selected for the presentation of technological details. Various groups of decorated objects are associated in the
hoard of Blanot (Cote-d'Or). Predominantly techniques of plastic deformation can be studied on flasks, vessels,
bracelets, rings and other jewellery. The hoard of Villethierry (Yonne) includes pins with decorated massic
head, worked by spinning on a lathe. A set of tools, used in decoration of metal work was found in the hoard of
Génélard (Saone-et-Loire). The study aims to find features in tool marks determining and distinguishing the
mentioned operations of the metal worker.
The technological information was obtained by the study of Burgundian bronze artifacts, combining optical
observation for the identification of tool marks, metallographic examination, X-ray photography and metal
analyses. Ethnoarchaeological and experimental studies were also considered. A multidisciplinary approach in
the study of ancient metallurgy and metalwork is proposed.

A series of heterochronous Alanian settlements of the 1st -early 2nd millennia A.D. have been singled out as
standard sites for the present study. The Alans formed a powerful union of Iranian-speaking tribes that played
an important role in the North Caucasus and Southern Russia at the time. While Alanian burial sites have been
well studied, their settlements have been neglected. Besides traditional archaeological investigation, geoarchaeological research has been undertaken. Since the majority of the said sites are fortified towns on
mountain ridges, the making of large-scale topographic maps pinpointing all visible building remains is of
primary importance. We succeeded in mapping fortified towns of Kiafar, Gornoe Ekho, and Achipse using the
method of all-round measuring of relief alterations. The method in many cases has proved to be more effective
than the aerial photograph and has enabled us to evaluate the pattern of the sites in question, while the aerial
photographs are useless, if a site is afforested or its relief too complicated.
We have also examinated building materials and their origin. Special attention paid to the building technique
has enabled us to date the sites in question more accurately and to estimate the degree of cultural influence of
adjacent regions such as Byzantium and Transcaucasia.
The geological evaluation of the sites has enabled us to investigate the geological situation at the time of the
formation of a site as well as the nature and intensity of its deterioration and the way of its conservation in
modern ecological conditions.

Recent work from this laboratory has confirmed that ESR spectroscopy may yield valuable information
concerning the provenance determination of classical marbles, provided that the data analysis is carried out
using a suitable, properly constructed database. Coupling of ESR results with some other physico-chemical
method (isotopic analysis, neutron activation analysis or others) may reduce or eliminate the remaining
uncertainties and provide a definitive answer to the marble provenance problem. In addition ESR measurements
are reasonably simple and fast, they require limited sample amounts (ca. 30 mg) and almost no sample
preparation.
On these basis we have decided to re-examine the whole subject and to set up a comprehensive, totally new
electron spin resonance database, starting from scratch.
The variables taken into account are the intensity and linewidth of the Mn2+ impurity commonly present in
marbles, the fraction of dolomitic Mn2+, which is also frequently detected, plus the occasional presence of other
paramagnetic impurities. Additional non ESR variables (grain size and others) are being considered for
inclusion into the database. Particular care has been devoted to the standardization procedures of data collection
and analysis, so as to obtain data which can be easily reproduced and expanded by other users.
Up to now more than 300 samples from at least ten different, historically relevant Mediterranean quarries have
been measured. In addition we have considered other relevant aspects of the problem. Among others they are
the detailed examination of parameters variability within a single quarrying district or within single blocks of
different dimensions, as well as the effect of weathering on the electron spin resonance parameters. Some work
has been also carried out on non-white marbles (“Cipollino Verde”).
All the data have been analyzed with the aid of multivariate statistical techniques. Selected examples and case
studies will be presented and discussed.

In some of the tombs (T. 26 and T. 139) of the Sannitic necropolis of Saticula (Sant'Agata dei Goti, Benevento),
spanning in age between the 6th and the 4th century B.C., a few very peculiar rings have been found, made of a
dark, partly altered metal alloy, and with a circular or ellipsoidal setting hosting various figures in relief (athlete,
running animal, human face etc.). More in particular, owing to their association with well dated ceramic
material, the rings can be assigned to the second half of the 4th century B.C.
On these objects several types of chemical and mineralogical studies have been performed, ranging from X-ray
diffractometry, to SEM and Electron Microprobe semiquantitative and punctual quantitative analysis, in order to
investigate the nature (and the proportions) of the metals present in the alloy, as well as their alteration products.
On the following Table are listed the more characteristic compositions recorded on some of the analyzed ring
fragments.

As can be seen, the alloy consists mainly of Pb, in dominant proportion on Sn, less Ag (probably associated to
Sn) and sporadic Cu. The proportion of tin in the alloy, however, is not always constant, ranging from an
average of few % to almost 100% in selected areas of the rings, probably due to immiscibility processes during
imperfect smelting.

Old cities around the world share problems like the overlapping of several cultural layers. This implies the
question, how to study previous structures preserving modern constructions? High resolution geophysical
techniques provide some answers. Preserving buildings on top, geophysics supply information concerning
extension and depth of buried structures. This kind of information leads subsequent archaeological excavations
to verify and obtain detailed information.
Mexico City is one of these cities. Prehispanic settlements are under the pavement of the present urban
development. Studies performed at Coyoacan have demonstrated that topographic, magnetic, electric and radar
surveys can identify the presence of buried structures under the pavement, even though there is some degree of
interference characteristic of urban environment. This synoptic approach, where techniques complement each
other, permits a better and more confident interpretation of geophysical results.
12. Some Analyses of Glazes from Assur in Mesopotamia/Iraq
Hans-Georg Bartel, Horst Hennig, Günter Kauschka
Humboldt University Berlin, Institute of Chemistry
The Berlin Vorderasiatisches Museum SMPK has a large collection of objects from excavations at Assur in
Mesopotamia/Iraq, operated by WALTER ANDRAE and his team between 1903 and 1914. Several glazes of
objects from this collection were studied:
Old-Assyrian spacer beans (glazed sintered quartz, 18th century BC)
Neo-Assyrian glazed pottery and knob plates (10th – 7th century BC)
Fragments of Parthian sarcophagus lids (2nd century BC – 3rd century AD)
The aim of this study is to compare glazes from Assur produced in different pre-Islamic periods with those of
other sites in ancient Mesopotamia. The composition of the glazes and the chemical nature of their colorants
were of specific interest.
The studies were carried out using a Akashi Alpha-9 scanning electron microscopy (SEM) fitted with a
qualitative energy-dispersive Röntec X-ray spectrometer (EDX).
The results obtained are:
(i) Generally, the compositions of the Assur glazes produced in periods (b) and (c) are similiar to those ones
excavated in Nippur [2], Nimrud [3], Kish [4], Niniveh[4], Uruk[5]. They are all alkaline glazes. The presence
of lead in yellow samples is due to its use as a colorant.
(ii) The methods of glazing are the application of glaze at the time of (b) or (c) and self-glazing at the time (a).
(iii) Green and blue glazes are always coloured by CuO, yellow ones by PbO, and black ones by MnO/FeO.
Silica was only used as colorant and opacifier in white glazes. Red coloured parts observed in green glazed
Parthian sarcophagi are caused by hematite crystals.

Obsidian is among the well known markers of cultural relations and trade in prehistory. As its conditions of
formation are very special, it is found in a limited number of districts and localities within Europe. Within the
framework of a Greek - Hungarian bilateral collaboration project, two focal point of this exchange system are
studied: the Aegean obsidian sources and the Carpathian source region. The main purpose is to find adequate
discriminating features, with minimum damage to the object. In the first phase, investigations are concentrated
to geological samples which are studied in a parallel manner. This approach is most important because
interaction of the distribution zones have already been demonstrated by single items. These very remarkable
pieces of occurrence, however, were found outside the typical area of distribution for the two source districts
where obsidian finds are extremely rare and, consequently, more precious - both to contemporary inhabitants of
the region and also to present day archaeological research.
Routine techniques of analyses are applied on source collected samples (NAA, XRF) complemented by
mineralogical and petrological analyses. Moreover, a database approach is used to collect all discriminating
features for a safe and reliable source identification. In the second phase of the project, special emphasis will be
given to "problem areas" and potential contact zones.
14. ESR spectroscopy of calcitic encrustations on archaeological finds,
serving as authenticity test

Terrestrial calcite encrusting archaeological pieces of art (mainly statues or vases) is often created during
millennia of accidental burial in the earth.
21
Archaeometry '98, Budapest
This material is usually removed from the archaeological surfaces during conservation. However it may
provide valuable information concerning the authenticity of the objects, in cases when the context is not
completely known. By means of Electron Paramagnetic Resonance spectroscopy the signal at g=2.0007 can
easily be detected on small pieces of these calcitic crusts. The existence of that signal provides indisputable
evidence for the authenticity of the relative object.
Recent archaeological inquiry on the authenticity of precious museum objects has enabled successful
implementation of the above spectrometric study. The results definitely showed authenticity of the related
objects.
EPR spectroscopy on calcitic crusts, regarded as an authenticity test, has the unique advantage of not affecting
the object itself. Additionally the process is easy, quick and requires a very limited mass of the material (0,1
gr.) for the entire measurement.
On the other hand the application is confined only to objects layered with the above kind of encrustation. Also
it is known that not every calcitic encrustation - even formed since some millennia - show detectable EPR
signals. On unfavourable circumstances the lack of any signal does not automatically mean that the object
under investigation is fake.
On-going study includes detailed analyses on radio-nuclides of the encrustation, EPR spectroscopy in low
temperatures, application of the process to archaeological finds from sub-marine environments (g=2.0033),
ivory and bone archaeological objects (g=2.0018).
15. Metallurgical evidence for local copper exploitation at Akrotiri, Thera:

The pre-volcanic basement of Thera island belongs to the Cycladic crystalline belt, often bearing metalliferous
parageneses. Copper mineralization in the form of the oxides malachite (CuCO3.Cu(OH)2) and chrysocolla
(CuSiO3.2H2O) is well known in the country rock, exposed at two sites of the caldera, namely at Thermia and
Athinios, hosted in the low-grade metamorphic formations.
Metallurgical studies were carried out on two crucibles, several pieces of high siliceous vitrified material and
one piece of semi-molten cupriferous green/blue schist, which come from the LBA excavation at Akrotiri, most
of them recently discovered and presented here for the first time.
Samples of the iron-copper mineralization along with the including Theran were also mineralogically and
geochemically analysed.
The existing results (Optical Microscopy, XRD, SEM, EDXA, ICP) provide strong indications that copper
smelting/melting activity took place at Akrotiri, using the local metal sources.
By further analytical studies any possible correlation between Theran copper sources and Akrotiri copper
objects will be investigated.
16. Characterisation of Ancient Pitches derived from pine wood by GC and
GC/MS
Ursula Baumer, Johann Koller
Doerner-Institut, Barer Strasse 29, 80799, Munich, Germany
Wood tar produced from pine wood was the origin of the pitches widely used in the past as glue, sealing
material, water-proof protective cover, lubricant and disinfectant. For millennia it was extracted from the
resinous wood of pine trees in a slow smouldering process (kiln carbonisation). Tar may also be obtained
directly by dry destillation of the balsamic resins collected from these trees.
In historical times pine pitches played an eminent role as protective coating and sealing material in shipbuilding.
Hence, many of the historical 'resin samples' in our investigation were taken from this field (caulking material).
22
Archaeometry '98, Budapest
Traces of pine pitch were also found in Roman wine amphorae and in materials used to embalm Egyptian
mummies in the era of the Old Kingdom. In more recent time (18th century) wood tar was used as mortar glue
in floor mosaics.
The present investigations were carried out by gas chromatography, while accurate peak identification was
achieved by gas chromatography/mass spectrometry.
The results showed evidence of natural resins components (bio-markers) and of products formed thereof by
destructive destillation (degradation-markers). This blend of bio-markers and degradation-markers is formed for
two reasons: a) in the kiln carbonisation process heat isomerisation reduces all but two of the resin acids
originally present in the wood, viz. stable dehydroabietic acid and residuals of abietic acid; b) under destructive
destillation conditions wood extractives are decomposed and resin portions are partially aromatised. This leads
to the formation of terpenoid hydrocarbons such as retene from resin acids.
When kiln carbonisation occurs under excessive temperatures it is retene that is predominantly being formed,
whereas dry destillation under pronounced oxygen influx leads mainly to the formation of oxo-dehydroabietic
acid.
Moreover, compounds (vinegar and methanol) released from wood in the course of dry distillation lead to the
formation of resin esters. Pitches obtained directly from balsamic resins do not contain these compounds and,
therefore, no resin esters either.
Wood tars from conifers are therefore differentiated from other pitches on account of the following three
characteristic components: Dehydroabietic acid, retene and methyl dehydroabietatd. Based on these
characteristics the caulking materials and the contents from the amphorae are therefore considered wood tars but
not the mortar glue where no evidence of resin esters was found.
17. Sample Size Considerations in Provenance and Related Studies
M.J. Baxter, S. Westwood
Dept. of Mathematics, Statistics and OR, The Nottingham Trent University, Clifton Campus, NOTTINGHAM NG11 8NS,
UK.
Provenance studies of ceramics, glass and metals frequently use multivariate statistical methods to identify
structure, or its absence, in compositional data sets. The paper reports on work aimed at providing guidance on
the sample sizes needed to detect different kinds of structure. This was stimulated by investigations into the
sample sizes needed to detect non-normality in lead isotope data, but has wider application.
Given a sample of n specimens, measured on p variables, multivariate methodology is often used to exhibit
separation into two or more groups. How large should n be to demonstrate separation convincingly, or show
that a sample is homogeneous? This is difficult to answer, since it depends on the structure which is usually
unknown in advance of data collection. An idealised model for an homogeneous data set is that it has a
multivariate normal distribution. Departures from normality, that exhibit multi-modality, indicate structure in a
set of data. Simulation of mixtures of normal distributions allows investigation of the sample sizes needed to
detect non-normality. Similarly, sub-sampling from large and real data sets that exhibit structure allows the
same question to be addressed.
We report on some simulation studies, with applications to lead isotope and glass compositional data sets.
Although some conclusions are rather obvious (e.g. small samples are usually adequate to identify well
separated groups), the main finding is that much larger sample sizes than those often used, or recommended,
may be needed to identify informative patterning in some common areas of archaeometric application.

Among the prehistoric and early historic methods of manufacturing pine tars in Central Europe are the Meiler,
in which an earth-covered stack of wood is partly burned and partly pyrolyzed, and the double-pot method, in
23
Archaeometry '98, Budapest
which wood chips in a perforated ceramic vessel are pyrolyzed by external heat and the tar is collected in a
second vessel bellow. Experimental tars made by both methods and remains of archaeological tar found at
Spandau near Berlin have been analyzed by 13C nuclear magnetic resonance spectrometry and their individual
constituents have been determined quantitatively by combined gas chromatography - mass spectrometry in
order to correlate the composition with the manufacturing method. Both experimental tars contain comparable
amounts of resin acids, but in the double-pot tar the degree of esterification (37%) is more than twice that found
in the Meiler tar (16%), indicating a higher operating temperature. The same conclusion follows from the higher
degree of aromatization in the double-pot tar (40%) over that in the Meiler tar (32%). The composition of the
archaeological tar differs radically from that of both experimental tars in that it contains a large number of
oxidized resin acid that cannot have been formed in the manufacturing process, but are the result of postdepositional weathering. The compositional data illustrate the problems and the promise of technological
inferences from chemical analysis.

Progress in sourcing studies of obsidian artefacts in the Northern Andine Area (NAAr) calls for a better
knowledge of potential source characteristics. We present new sources and revisit the chemical characterization
of NAAr geological obsidians.
Results are given for samples of the Rio Hondo (Colombia) and the Sierra de Guamani (SG) (Ecuador) sources
previously analysed. New samplings include obsidians from the Mullumica and Callejones SG flows. The
Mullumica flows deserve a special effort of characterization, due to their mixed magma compositions, because
they are often cited as possible sources for NAAr artefacts.
Obsidians from newly sampled potential sources are in Ecuador that of Rio Guambi (downward the SG), two
outcrops on the Cotopaxi volcano (30 km S of the SG) and in Southern Colombia that of Rio Granates and
pseudo-tektites from the Cali region.
For the first time, obsidian sources of the NAAr are characterized by ICP-AES/MS (35 element contents
determined). As PIXE analyses (13 elements) on natural and internal surfaces are used in artefacts sourcing
studies in the NAAr, the relative merits of ICP and PIXE for the discrimination between sources will be
commented.
Other source obsidian parameters will be discussed : their fission track ages, used for composition/age group
definitions, and Mössbauer and ESR data, as part of an on-going program on the potentialities of these
approaches in obsidian sourcing.
These data will be compared to the results obtained so far on artefacts for the study of obsidian procurement and
trading in NAAr prehispanic cultures.

A research project has been carried out by an interdisciplinary team (geology-archaeology) in order to establish
the provenance of some roman marble artefacts from different Romanian museums. One of the conclusions was
24
Archaeometry '98, Budapest
that the single roman marble quarry, proved by geological and archaeological arguments, was those from
Bucova (Caras-Severin County).
The maximum grain size of the calcite granoblasts, the accessory constituents and the structure were
established with the aid of a polarising microscope. The isotope ratios and the chemical analyses (ICP-MS)
were obtained with a mass spectrometer "Micromass 602C" in GTI-BVFA Laboratories in Vienna. The
deviation from a conventional standard (PDB) was expressed as δ13C and δ18O in parts per thousand (‰).
The isotopic ratios, plotted in a δ13C versus δ18O diagram are showing 3 individual fields. Keeping in mind the
place from where the samples were collected and the isotopic ratios, it was demonstrated that δ18O decrease
from the central part of the marble lens to the contact with the crystalline schists. In the roman quarry from
Bucova, located in the central part of the marble lens, the isotopic composition is uniform on a length of 10-12
m. The differences between values are less than -0.72‰ δ18O and less than 0.22 ‰ δ13C.

Thirty years ago, a series of experiments achieved in Great Britain established that low frequency (between 1
kHz and 10 kHz) E.M. Slingram apparatus using two magnetic dipoles could be used in order to measure the
apparent magnetic susceptibility in archaeological context. Following these first experiments, measurements
performed with the SH3 prototype (1.50 m intercoil distance and 35° inclination of the coils) proved that the
simultaneous measurement of both apparent conductivity and apparent susceptibility was feasible. Intercoil
spacing of 1.50 m proved to be a convenient compromise between depth of investigation compatible with most
archaeological sites and a reasonable lateral resolution for the location of the features. Ten years ago, after
intensive field use and synthetic modelling, it was established that perpendicular coil orientation was optimal in
terms of depth of investigation without increasing the intercoil distance. Moreover, the use of a double
frequency might offer the possibility of getting the quadrature susceptibility.
We present here the first series of tests of the CS150 apparatus (conductivitymeter-susceptibilitymeter of 150
cm intercoil distance) which has perpendicular (PERP) coils configuration and operates at 4 kHz and 10 kHz
frequencies. It has been used over both artificial features at a test site (Garchy, France) and over archaeological
sites (Iron Age and Roman Period). Thanks to an automatic acquisition system, it offers the possibility of
measuring while moving, which enables to survey an area of the order of 2 ha per day (at 1 meter profile
separation), this rate being equivalent to the one of continuous electrical systems developed in Garchy
(MUCEP).
22. Etruscan tin-rich slags from Populonia (Tuscany, Italy): a preliminary

The Gulf of Baratti, extending beneath the Etruscan town of Populonia, has represented one of the most
important early iron metalworking centres in Europe as witnessed by the huge heaps of slags discharged over
five centuries (VI-I cent. BC) by the Etruscans and the Romans. In addition to iron, however, Etruscans are
thought to have also exploited and smelted base-metal (Cu, Pb, Sn) in the Baratti area (cf. Crew, 1991),
although the only direct evidences of this are so far represented by some copper slags described and analyzed by
Sperl (1980).
At the beginning of a research project on metal production in the Populonia area, we have analyzed a number of
slags from the so called “A” Building in the Poggio della Porcareccia industrial zone (VI-IV century BC).
25
Archaeometry '98, Budapest
Several samples of slags were taken from an embankment constituting the foundation of a IV cent. BC-building.
They include both tapping and furnace slags of small size (on average 130 cm3), mostly magnetic, composed of
dominant fayalitic olivine and wüstite ± magnetite and quartz. The occurrence of micron-sized droplets of
metallic tin (bulk contents in the order of 0.01-0.03 %) is especially noteworthy. This feature, together with the
presence of metallic Bi and W-rich phases in the groundmass, could fingerprint the processing of base-metal
ores of “inland” provenance, i.e. coming from the nearby Cu-Pb-(Zn, Ag, Sn) Campiglia M.ma-M.te Valerio
deposits.

23. An osteological analysis of elk (Alces alces L.) bones from excavations in
the Lubâna Lake Basin, Eastern Latvia.
Sergey Berdnikov
University of Latvia Riga, Latvia, e-mail: sb50002@lanet.lv
The Lubâna marshy meadows are one of the most important Stone Age investigation regions in the East Baltic
area. This study deals with elk bones from the Abora, Zvejsalas, Zvidze and Malmuta River Estuary sites, dated
from the Mesolithic and Neolithic periods.
A total of 12120 animal bones, tooth and antler fragments were unearthed during excavations led by J. Loze in
1964 -1990. Elk was the animal species that was most exploited by the human population. Its bones occupy the
first place among all herbivores in this material, as well as in materials from the entire Eastern Baltic, allowing
to make a complete osteological analysis of this species.
Some problems related to quantification are examined, such as the estimation of the numbers of individuals of
elk for each site. Two quantitative methods are used here: counting of the numbers of fragments and of the
minimum numbers of individuals (MNI). Bone measurements were made for all fragments. These results were
compared with K. Paaver`s analyses (1965) of previously excavated materials from Lubâna and with bone data
from other Eastern Baltic Mesolithic and Neolithic sites.
The results are additional to K. Paaver`s data. The ecology of the area is discussed with respect to the vegetation
history and the adaptation of elk.
24. The archaeobotanical analysis of the Middle Bronze Age settlement at
Bölcske-Vörösgyír
Brigitta Berzsenyi, Ferenc Gyulai
Archaeological Institute of the Hungarian Academy of Sciences Budapest
The analysis of the archaeobotanical site material (Bölcske-Vörösgyír) allows us to reconstruct a more specific
period of the domestic Bronze Age agriculture and summarize the questions regarding this period. As
agriculture can not be separated from the climatic conditions we first examined the vegetation and the domestic
Middle Bronze Age culture management, followed by the life style of Bronze Age people.
Fortunately Bölcske-Vörösgyír site samples taken from several areas reveal the presence of grain crop remains
with the attendant weed flora.
The examination of the above mentioned specimens revealed species of not yet found in other Bronze Age
excavations (in Hungary). There is a continuous development between two cultures (the early period of the
Nagyrév culture and the Middle Bronze Age Vatya culture) when examined from point of view both
archaeobotanical and archaeological.
From the plant remains found in the different layers of the site we can deduce that the inhabitants were not only
growing cereals and legumes but they were also collecting wild fruits. The most important grain was the wheat.
Barley was secondary in importance. Among the chaff wheat we found emmer (Triticum turgidum subsp.
dicoccum). However spelt (Triticum aestivum subsp. spelta) was rarely encountered. The consumption of
26
Archaeometry '98, Budapest
legumes (such as lentils, peas, broad-bean) was considerable and were augmented by other species during the
Middle Bronze Age bitter vetch (Vicia ervilia).
As there were very few non-grain remains in the samples found on the sites we can make the conservation that
the cultivation of these crops used several techniques in removing unwanted weeds and the chaff leaf.
Furthermore these weeds seeds also tell us that the soil was furtive and fertiliser (manure) free.
After the analysis of the Bronze Age remains found at the sites we can assume that the inhabitants in their
search for vitamin rich nourishment looked to the fruits and berries found nearby. The following samples gave
proof to the human consumption stock piling and possible preparation of grain: dewberry (Rubus ceasius), elder
(Sambucus nigra), red elder (Sambucus racemosus), cornelian cherry (Cornus mas), blackthorn (Prunus
spinoza).
Based upon the results of the examination of the above material we can assume that the settlers at these sites
were established plant cultivators.

In a study of the faunal remains excavated since 1990 at Sagalassos (Burdur Prov., Turkey), information on
subsistence patterns and animal husbandry practices have been gathered. Considering the importance of
ovicaprines at Sagalassos, a more detailed study on their historical use and management was started. Therefore,
a reconstruction of the former diet, the absolute age and season of death seemed most informative. By
establishing an unambiguous relationship between the diet and dental microwear on recent ovicaprine teeth, an
attempt is made to interpret the dental microwear on fossil teeth. Detailed qualitative and quantitative
information on the food consumed by modern animals, is gathered through the direct observation method. It is
attempted to determine the age and season of death of the animals through a comparative study of the growth
rings in recent and ancient tooth cementum. To identify the excavated teeth to species level the possibilities of
the ultrastructure of the enamel and of the stable isotopes of carbon are explored.

A Korean cast iron representation of a "warrior on horseback" of a form identical to fifth and sixth century
ceramic vessels was examined. The ceramic figures appear to function both as container and dispenser of fluids,
whereas the cast iron object does not have this function. The cast iron horse's core, once filled with casting
sand, is open and does not allow the storage of fluids. At first, this apparent lack of functionality cast some
doubt upon the authenticity of the object; but, the appearance of both clay and iron horse figures has been
documented in the Korean archaeological record. Scholars have reported the appearance of clay and iron horse
figurines, wearing saddles and bits, that appear to be votive objects.
Steel objects can be dated by radiocarbon analysis if charcoal was used in the manufacture. Direct radiocarbon
analysis using AMS has yielded a 14C content of 1.65 q 0.16 pMC, equivalent to an apparent age of 33000 B.P.
This implies that instead of charcoal, coal was being used in the manufacture of the steel. In the past, it has
generally been assumed that the use of coal in Chinese and Korean steel making did not occur until relatively
recently in China. However, some research suggests that coal was used earlier. We examine cast iron artifacts
from the First Millennium, BC and AD of Chinese contexts to test for the earliest coal use in iron production.

the Central Andes

This presentation will discuss the range of metal working techniques employed from 1000 AD to 1540 AD in
the Upper Mantaro Valley, Peru. During these five centuries the population of the region underwent important
changes in socio-political organization, which in turn had implications on the economy. Changes in the
distribution, amount and composition of the metal goods, especially copper and copper-alloy artifacts, have
been correlated with the incorporation of Wanka chiefdoms into the Inca state around 1450 AD. During the Inca
occupation the overall amount of copper objects increased and access to them also widened to include an almost
equal proportion of commoners to elites. The debut of bronzes also dates to the Inca period. Bronze objects did
not, however, replace copper and arsenical copper artifacts in the archaeological record of the Mantaro Valley.
The coexistence of objects with distinct compositions prompted this study, which documents whether changes
in the alloy compositions were accompanied techniques of working. Metallography, SEM/EDS, and ICP-OES
are used to examine microstructure and composition.

Tsagaan Agui Cave lies south of the Gobi Altai massif. Sedimentary fill includes intercalated loess, sand, and
clay units, with some soil horizons, as well as ironstone concretions, gypsum, éboulis, gravel beds, alluvial and
terra rosa deposits in deep layers. In Pit 2, Layer 3 contained Levallois-like points, while Layers 4 and 5 had
flakes and burin-like tools, among other artefacts. Deeper layers yielded retouched flakes, burins, notched tools,
and scrapers. ESR was used to date seven subsamples from one Equus and one cervid tooth, both from Layer 4.
ESR dating uses the radiation-sensitive signal found in well crystallized fossil tooth enamel, but not in modern
teeth to date fossil teeth. The equivalent radiation dose needed to produce the observed ESR signal is the
integral with respect to time of the natural, environmental dose rate experienced by the tooth after its deposition.
Since the age depends on the uranium (U) uptake history assumed, three limiting cases are calculated assuming
early U uptake (EU), continuous (linear) uptake (LU), and recent U uptake (RU), respectively the minimum,
median, and maximum ages. ESR isochron dating requires numerous subsamples from large mammal teeth, but
eliminates in situ dose measurements or sediment sampling, because the tooth acts as its own dosimeter. The
teeth yielded a mean age 70.6 + 6.3 ka (EU), 85.1 + 6.3 ka (LU), and 99.7 + 6.8 ka (RU). The preliminary
isochron gave an LU age of 97 ka with an external dose rate of 301 mGray/y. 230Th/234U dentine dates should
clarify which U uptake model is best. Therefore, Layer 4 dates from at least 70 + 7 ka, but may be as old as 100
+ 7 ka.
29. Evidence for oxidised lipids in archaeological ceramic vessels

Solvent extractable lipids preserved in ancient ceramic vessels are proving to be a value source of information
relating to vessel use and palaeodiet (Evershed et al., 1997). Assessments on the origins of these components
rely on a detailed knowledge of their chemical alteration during vessel use and burial. In order to provide new
28
Archaeometry '98, Budapest
information on lipid degradation in archaeological pottery, chemical investigations (gas chromatography, GC,
and GC/mass spectrometry, GC/MS) have been performed on ceramic vessels recovered from both arid and
water-logged burial environments: Qasr Ibrîm, Upper Egypt, ca. 6th century AD and Chalain lake dwellings in
Jura (France), Final Neolithic, ca. 3000 BC, respectively.
GC profiles of total lipid extracts (TLE) of the Qasr Ibrîm vessels revealed the presence of a series of
dicarboxylic acids, with azelaic acid being the predominant component. The TLEs of the Chalain samples were
free from oxidised lipids, however, when the insoluble solvent extracted residue was saponified in order to
investigate compounds chemically bound to the pot matrix, a mixture of components were obtained dominated
by dicarboxylic acids and mono- and dihydroxy fatty acids. These components result from oxidation and/or
hydroxylation of the double bonds of unsaturated fatty acids (Gillan and Johns, 1982). This constitutes the first
evidence for the presence of lipid oxidation products in archaeological ceramics providing important
information concerning the fate of unsaturated lipids in pottery vessels. These results will have potentially
important consequences for the assignment of natural sources of commodities processed in ceramic vessels.

Global chemical characterisation of ceramic bodies are commonly used to determine their provenance and also
the workshops where they were manufactured. However, in some cases, the chemical characterisation of its
different mineral inclusions should be considered for provenance determinations. In fact, the trace element
contents of the mineral inclusions found in different volcanic areas with recent volcanism may be characteristic
of a provenance.
The analyses of the mineral inclusions are ticklish, as those inclusions are not easy to identify on thick sections
of the ceramics and point methods have to be used. Here the applied analytical techniques are PIXE, SEM and
LA-ICP-MS. These different point methods give the complementary information we can obtain on the
inclusions concentrations at present.
We started by analysing known mineral inclusions from known provenance: olivines, augites, orthoses,
sanidines, garnets. The concentrations obtained by the three methods, mainly for trace elements, show if they
are uniformly distributed through the silicates and if it is possible to discriminate between different origins. We
are also able to appraise detection limits of each technique and their possibilities for this kind of analysis.
As there are three different volcanic areas in Italy, these techniques are applied to a few roman amphorae
samples from Pian di Spille in the Latium and Mondragone on the Campanian coast, as well as to samples from
the wreck of Le Grand Congloué (submerged near Marseilles).

In the last twenty years Pb-isotopic analysis has been often applied to archaeological provenance studies. Our
group, consisting of archaeologists, metallogenists and geochemists, took recently the opportunity to investigate
29
Archaeometry '98, Budapest
a few Roman objects found in two different localities of Southern Italy: at the Ischia island and in the town of
Pompeii. In Ischia the analyzed objects belong to an area, located near the Carta Romana beach, possibly
hosting a smelting center. They consist of lead ingots, lead fragments, chunks of galena ore and small
concentric artifacts of lithargirium, derived from in situ cupellation processes. Pb-isotopic analyses from these
objects gave the following results for the galena ore:
206
Pb/204Pb
207
Pb/204Pb
208
Pb/204Pb
18.338
15.651
38.505
18.272
15.647
38.442
The data from the lead ingots and fragments, and from the Pb-oxydes are:
206
Pb/204Pb
207
Pb/204Pb
208
Pb/204Pb
18.760
15.727
39.138
18.674
15.670
38.931
The Pompeii objects, mostly consisting of fragments of fistulae from the roman aqueduct, gave results (data are
still preliminary) spanning between 18.10 `and 18.66 (206Pb/204Pb), between 15.63 and 15.72 (207Pb/204Pb) and
between 38.21 and 38.98 (208Pb/204Pb ).
The isotopic values of the lead objects from Ischia point to an origin (also substantiated by the seals on the
ingots) from the Spanish mines of Nova Carthago, whereas the galena ore could be derived either from the
Tuscanian mines or from other Spanish ores, of possible Mesozoic age.
The data measured on the fistulae of Pompeii point, instead, to a more complex origin, possibly involving many
successive smelting and mixing processes. In fact, the Pb-isotopic values show a continuum on the CR-SK
growth curves, with two end members, one of which coincides with the average data of the Lower Cambrian
mines in Sardinia and the other with the Miocenic volcanic-hosted ores of south-eastern Spain.
32. Characterisation of “Embalming Resins” from ancient Egyptian
mummies
S.A. Buckley, A.W. Stott, R.P. Evershed
Organic Geochemistry Unit, School of Chemistry, Cantock’s Close, University of Bristol, BS8 1TS
There has long been a fascination with the mummies of ancient Egypt. Despite this however, surprisingly little
is known about the so-called “art” of mummification. In fact very few analytical studies have been carried out to
gain insight into the sources and nature of the “resins” employed in mummification [1-5]. A number of
preservatives have been proposed, including true resins, e.g. coniferous resins (diterpenoids) and nonconiferous Pistacia resins (triterpenoids), gum resins, e.g. frankincense and myrrh, bitumen, pitch, honey and
beeswax.
We now have the opportunity in our laboratory to carry out a comprehensive analytical study on a relatively
large number of ancient Egyptian mummy samples from a wide range of dates, status’, geographical locations
and contexts. In particular, a focus will be a thorough and systematic approach to the study of a number of
mummies, carrying out round body sampling. This is an important aspect of the research since the literature
suggests that materials were applied to various parts of the body depending on the particular purpose and
significance. Due to the complex nature of the aged organic materials likely to be present we have employed a
dual approach utilising: (i) solvent extraction followed by GC/MS, and (ii) a combined sequential TD-GC/MS
(310°C/10s) and Py-GC/MS (610°C/10s) (Chemical Data Systems 1000 Pyroprobe) methodology to allow the
convenient study of both “free” and “bound” biomarkers deriving from the “embalming resins” in these
samples. A distinct advantage of employing sequential TD-GC/MS and Py-GC/MS is the small sample sizes
(ca. 0.1 mg) required allowing rapid screening of a larger number of samples and micro-scale analysis
facilitating the essentially non-destructive analysis of the mummified bodies, thus ultimately aiding sampling
from historically valuable museum specimens. However, solvent extraction also provides some valuable
30
Archaeometry '98, Budapest
information which is not
31
Archaeometry '98, Budapest
obtained using TD alone. This demonstrates that more than one approach may be necessary if the “resins” are to
be satisfactorily characterised.

33. Archaeometric Preliminary Study of Volcanic Rock Millstones from
Pompei - the Problem of their Provenance
L. Buffone*, S. Lorenzoni**, M. Pallara**, E. Zanettin**
*Soprintendenza archeologica di Pompei, Italy
**Universitá degli Studi di Bari, Dipartimento Geomineralogico, Bari, Italy
29 samples of "Pompeian" type and "disc" type millstones from Pompei have been studied by both petrological
and chemical methods, to define their lithological constitution. Moreover, field researches have been performed
in the Bolsena-Vico-Bracciano and Roccamonfina regions to locate the source area of the millstones.
The millstones studied are constituted of leucite-pyroxene (±olivine, sanidine, haüyne) tephrites and tephritesphonolites belonging to four lithological groups, different in composition and/or structure and attributable to
different volcanic formations. Only one "disc" type millstone is constituted of basalt.
P. Nicotera (1950) considers Roccamonfina volcano the probable source of the Pompei millstones. Instead,
D.P.S. Peacock (1986) states that the millstones of Pompei come from a lava flow of the Orvieto zone. Our
researches indicate that the Pompei millstones come from different localities. The tephrite millstones are
attributable to the Roccamonfina volcano, and precisely to the lava flows of its western slopes, facing the
Garigliano river. The tephrite-phonolite millstones are attributable to the lava flow outcropping near Orvieto.
The basalt millstone is referable to the Mt. Etna volcano. Only a few millstones might come from the BolsenaVico-Bracciano area.

This paper shows the materials for which and the extent to which DNA analysis can be a useful tool in
archaeometry. In the framework of an archaeometric project at the Institute of Anthropology, Goettingen, the
content of both historic and prehistoric objects is analysed. The objects are of different types, such as:
prehistoric stone artefacts, parchments, glues, various contents of vessels, and prehistoric rock art paintings.
The paper will focus on the identification of the animal or plant species of origin of a specimen by ancient DNA
analysis. The accuracy of the DNA method will be compared with other techniques such as crossover immunoelectrophoresis (CIEP) or enzyme-linked immunoabsorbant assay (ELISA).
DNA results are given for rock art pigments and blood residues on stone tools.

35. Correlation of barium and strontium during trophic-level
biopurification and its osteoarchaeological implications
James H. Burton, T. Douglas Price, W. D. Middleton
Department of Anthropology, University of Wisconsin-Madison
In order to more fully understand the relationship between diet and bone levels of barium and strontium, we
analayzed by ICP spectroscopy thousands of modern mammal bones, plants, and soils. Our results reveal a
strong correlation between barium and strontium, relative to calcium, with increasing trophic position as a result
of biopurification.
This correlation indicates that bones present excellent statistical averages of local environmental barium and
strontium levels and thus that strontium isotope ratios in bone can reflect regional geology despite intrinsic local
variability in soil Sr87/86 ratios. This is further supported by observed homogeneity in bone Sr87/86 ratios.
A second implication of this correlation is that, by measuring both barium and strontium in fossil bones we can
assess their post-mortem contamination directly rather than relying on proxies such as Ca/P ratios and
crystallinity indices.

One of the most secure procedures for the formation of control groups in pottery provenance studies using
chemical analysis, has been considered to be the use of kiln wasters, which are assumed to produce chemical
profiles representative of local production.
The excavation of a pottery kiln dating to the Late Minoan I period at Kommos provides an opportunity for the
analytical investigation of a certain production assemblage. Fifty-seven samples were analysed by INAA, XRF,
thin section petrography, SEM and XRD, to characterise, in chemical and mineralogical terms, the ceramic
fabrics produced in the kiln and to investigate their technology. The majority of the pottery analysed belonged
to three major, calcareous petrographic fabric groups, differentiated from each other on the basis of the
inclusions’ grain size.
Chemical data, however, revealed some extreme variations in the alkaline elemental contents, which did not
coincide with the idea of a common provenance. Further examination by XRD and SEM has provided important
information about the mineral composition and the firing temperatures of each sample. It is clear that the
chemical groups correlate with the firing temperature of the different vessels. This is explained as selective
alteration and contamination in the burial environment, related to the existence of different characteristics
(mainly, in mineralogy, vitrification and microstructure) in the fired products.
Kiln sites contain pottery of widely varying firing temperature, therefore the result of this study provide an
important observation on the use of such material in control groups. The use of combined mineralogical and
chemical techniques is recommended in order to avoid erroneous conclusions.

The present paper concerns the first chemical and microstructural study of paleovenetian thin plates. During an
excavation in Vicenza (Italy) in 1959, 200 thin plates decorated with punch and chisel, with rectangular and
33
Archaeometry '98, Budapest
circular shape, were found. The decorations follow the paleovenetian people style, but Celtic and Etruscan
influences are evident. Paleovenetian is the name given to the Indoeuropean population living, in the 1st
millennium BC, in the territory currently known as Veneto (North-Eastern Italy).
The plates were produced from V to II century BC with votive aims. As their artistic value and good condition,
any analysis has been never previously performed on these findings.
In the present paper the chemical and microstructural characterization of 14 samples is presented.
All the samples were examined with non-destructive techniques (SEM, EDS, and EDXRF). A small fragment
was observed with SEM in cross section and analysed with AAS to confirm the composition data obtained with
the other methods.
The thin plates are bronze made at low Sn and Pb content, in a few samples Fe and Zn traces were found. Cuoxide and Sulphur compounds were evidenced on the surface.
The chemical composition, microstructure, surface element distribution and thickness of corroded layers were
determined, the production technology was investigated.

In this paper we are studied one hundred eighteen three ceramics vessels belonging to the Late Neolithic Age
and Late Bronze Age, originating in the Spanish archaeological sites. The settlements are located in the
province of Granada (South of Spain), and province of Ciudad Real (Central Spain).
These materials have been investigated by X-Ray Diffraction, Chemical and Physical Analysis and Thin
section.
The results obtained show evidence that these vessels were manufactured with a particular purpose in
accordance with the utility of ceramic. Data confirmed the existence of three clearly differentiated groups, one
consisting of cook ceramics, the second group is consistent with other pieces to store cereals, while the third
group corresponds to the ceramics with no precise use.
Finally, we come to the conclusion that there is evidence of relation between manufacturing processes (content
and size of the degreaseant, presence and absence of carbonates and porosity), and use of ceramics.

Email: hchaya@juno.com
Chemical and physical properties of archaeological soils are valuable indicators of past human settlement
activity. Results from archaeological soil analyses indicate factors such as intensity and location of population
and middens. For most archaeologists, cost and portability of such studies are important.
A study of archaeological soils from two sites is described; an Aleutian Island site occupied for perhaps 4,000
years by marine hunter-gatherers and a pre-historic Mohawk Indian site in the Mohawk Valley of NY State,
USA. This paper describes simple analytical procedures to determine soil phosphorus (total, organic, and
inorganic),organic carbon content, pH and electric conductivity of moist soils. In the process, measured soil
properties were compared to artifacts found at both sites in the same soil. Students can perform most of the
analyses. In the field, measurements of pH and soil conductivity are performed by portable equipment so that
both of these properties can be measured on the same sample preparation.
At times, interesting and useful correlations were found between properties of a soil sample and the artifacts
found at the site.. In the field, portable testing of soil can give a probable indication that something of value is
being excavated, an immediate help in the direction of further excavation. Laboratory evaluation of our soil
samples and other artifacts demonstrated that rapid exploratory testing gave a quick indication of further
profitable work. The analytical procedures described are simple and rapid. The equipment is portable and
economical to obtain.
41. Early metallurgy in the Eurasian steppe: minerals and slags analysis
from Kargaly (Russia)

*Academy of Sciences, Moscow
**Museo Arqueológico Nacional, Madrid
Kargaly (Orenburg, Russia) is a vast copper-bearing region in the Eurasian steppe. Minerals are located as
pockets, thin veins and substitution fillings in the sandstone of the area. Thousands of pits and galleries
excavated from Late Bronze Age up to 19th century are visible.
After a survey of all mining districts, digging seasons have been located at Gorny, a prehistoric site where
copper production was the main economic activity. Slags, mineral storage place, moulds, fireplaces, raw copper,
instruments and so one have been found. Radiocarbon dates span between 1700-1500 cal BC.
Archaeometallurgical research objectives are focused, in a first step, in the determination of the copper smelting
technology. Then, copper minerals, slags and copper prills have been analysed using X-ray fluorescence
spectroscopy (EDX), scanning electronic microscopy and conventional metallographic techniques.
Mineral use to be copper carbonates (malachite, azurite), with gangue constituted by silica and small amounts of
calcium, iron, aluminium, barium and potassium oxides. Very low percents of trace elements such as silver and
antimony have been detected.
Well-formed slags (fayalite type) are very scarce, being abundant the furnace conglomerates rich in copper
prills and cuprite. Copper sulphide is also formed, as mate nodules and prills rim. There are no tapped slags.
The analytical set leads us to draw the features of a primitive copper smelting process with low copper recovery
rate because of the difficulty to achieve temperature for a good separation of metal and slag.

If there is a disease which signals poverty, it is tuberculosis (TB) - indeed for archaeological populations, no
other reliable marker is available. Unfortunately, the “diagnosis” of ancient tuberculosis (TB) is fraught with
problems. It relies, currently, on finding bone lesions consistent with tubercular disease only to be expected in
a low percentage of the diseased population and on the demonstration, in those lesions, of an insertion element,
IS 6110, diagnostic for the Mycobacterium tuberculosis complex. We present a novel alternative - the survival
of lipids in ancient ceramics, coprolites and bog bodies suggests that characteristic tubercular lipids (mycolic
acids) may be biomarkers for tuberculosis (TB). Mycolic acids are stable 60 to 90 carbon, 3-hydroxy, 2-long
alkyl branched fatty acids which are major, covalently bound components of the cell envelope of mycobacteria.
Preliminary studies showed the presence of mycolic acids in mediaeval bones [2]. The Newcastle Infirmary
site, excavated in early 1997, has provided material for an in-depth investigation. Historical records show a
high death rate due to "consumption" and some of the bones show lesions characteristic of TB. Mid-shaft rib
samples, chest cavity soil samples and distal soil samples were collected. Standard chromatographic profiles of
mycolic acids were generated from M. tuberculosis using a selective extraction protocol and high performance
liquid chromatography analysis of methylanthryl esters with fluorescence detection [1]; archaeological material
was processed in the same manner. Results obtained show a very close agreement with recorded death rates we believe we have a biomarker for ancient TB.

43. Archeometry at the Aquincum Museum
Alice Choyke
Aquincum Museum, Budapest
Traditionally, the tools archaeologists use in trying to understand the past have usually included the form and
style of the objects found during excavations together with the location and type of the sites they are found in.
These are all things that can be described and measured by the archaeologists themselves either in the field or
later in the laboratory. However, with the growth of technological possibilities in other research areas, new
vistas are opening for archaeologists. They are now able to ask questions which can be best answered by data
not immediately available by ordinary archaeological methods.
For a number of years, specialists in the departments of Prehistoric and Medieval archaeology at the Budapest
Historical Museum and Roman archaeology at its branch museum at Aquincum have increasingly exploited the
expertise of scientists in numerous ways.
Excavation is a very expensive process. New remote sensing geomagnetic methods developed by Sándor Puszta
and his team of Fractal Bt. in the Geophysical department of Loránd Eötvös University have enabled our
archaeologists to confirm and pinpoint the locations of sites and features within them without resorting to more
intrusive methods such as digging.
Archaeologists also rely on specialists to tell them something about the animals and plants our ancestors here in
the territory of modern day Budapest exploited. As finer excavation methods, including screening and flotation,
are employed whole new species, especially fish have been found by the archaeozoologist at the Aquincum
museum, Alice Choyke. Recently plant remains have begun to be regularly studied from Roman period
excavations: Ferenc Gyulai, of the Archaeological Institute of the Hungarian Academy of Sciences and now
36
Archaeometry '98, Budapest
Orsolya Dálnoki, a student in the Institute of Archaeological Sciences of the Loránd Eötvös University have
collected seed samples and subjected them to analyses using a special Macintosh based image processing
system enabling them to measure larger quantities of seeds.
Archaeologists also wish to know something about the physical environment ancient people lived in as this can
have a strong limiting effect on where they located their settlements and why these settlements were abandoned.
Reconstructing the soil formation processes at archaeological sites can be a powerful tool in understanding local
environments. György Füleky, chairman of the Department of Agrochemistry and Pedology at the University of
Gödöllő has begun to regularly test soil types from excavations in areas both outside the Military town and in
the Civil town.
More details of the environment can be provided by studying the kinds of wood, often preserved through
burning, found on archaeological sites. This can yield important data to specialists on the history of a tree
species in Pannonia but also more clues on the climatic circumstances ancient peoples lived in. Károly Babos of
the Department of Plant Organology of the Loránd Eötvös University has carried out a number of studies in this
regard. András Grynaeus, who runs the Dendrochronology Laboratory in the Institute of Archaeological
Sciences of the same university has also examined large timbers from a site outside the Aquincum Military
town.
Another constant problem archaeologists are faced with is dating the settlements they find and, especially
judging the relative dates of the features within them. Until now specialists have had to depend on typological
dating methods, radiocarbon dating and potentially dendro- chronological studies. Péter Márton of the Institute
of Geophysics of the Loránd Eötvös University has studied numerous ovens and fireplaces from various periods
in the hope of establishing a timeline through archaeomagnetic dating of burnt features. Curiously, while this
dating method has proven effective for dating burnt features at prehistoric and medieval sites, multiple samples
taken from burnt Roman features display much more variability. The reason for this interesting discrepancy is
unclear and awaits future work.
The final category of research where archaeologists at our museum have regularly turned to specials is that of
material analysis. Such analyses can take the form of X-rays to determine the exact nature of corroded iron
objects or details of the manufacture of other metal artifacts. Gábor Hutay of the restoration department at the
Hungarian National Museum, Ottó Léc and József Király of the Isotope Institute of the Hungarian Academy of
Sciences and Márta Járó of the Hungarian National Museum have carried out such valuable work for us.
Work has also been carried out on the material of grinding bowls and plaster to attempt in the former case to
distinguish individual workshops (failed) and plastering on walls in complex archaeological structures. Work on
the former was done by Sándor Józsa of the department of Geology of the Loránd Eötvös University. L. Kriston
at the Criminology Institute, Márta Járó have worked on the latter kind of problem.
Questions about trade and economic systems are frequently posed by archaeologists, especially those working
in proto-historic periods. Locations of local and foreign quarries from where the stone of walls and statues come
from tell us something about the value of individual objects and economic connections on local and
international levels. Pál Müller of the Geology Department of the Loránd Eötvös University, Ferenc Schweitzer,
and Müller from Vienna have worked on identification of stone wall materials and statuary material for the
Aquincum museum. The results have not always been expected but always useful.
It has been our experience at the Budapest Historical Museum that bringing in specialists has allowed us to
broaden the scope of the questions we can ask about past lifeways. Sometimes the answers we get are
unexpected and often lead to entirely new questions. In the future it is our hope, not only to continue but to
increase the regular use we make of new scientific developments in other fields.
44. TL-Dating of Chichen Itza, Yucatan, Mexico
Heajoo Chung, Peter Schaaf, Angel Ramírez
UNAM Ciudad Universitaria Circuito Exterior s/n 04510 Mexico City, Mexico
Chichen Itza is a Postclassic (A.D. 1000-1400) archaeological site in northern part of Yucatan peninsula of
Mexico. Chichen Itza was understood as the last glory of Mayan civilization, invaded by the Toltecs, the
Central Mexican military power about A.D. 1000. The dating of Chichen Itza is based upon Spanish chronicles,
however, there is a lot of discussion surrounding the chronology. Mayan archaeologists claimed that when the
Toltec's Tula was flourishing (A.D.: 1200-1400), Chichen Itza had already declined. This argument is sustained
37
Archaeometry '98, Budapest
by C14 dating of archaeological sites in northern Yucatan, in which we have no dates that surpass A.D. 1000.
But researchers still debates this topic, and therefore, the precise dating of the site is fundamental for
understanding the history of the city.
We have abundant diagnostic ceramics from this period which contain volcanic glass and quartz. We tried to
date the last firing time of these ceramics by thermoluminescence analysis, thus providing complementary ages
obtained by a different method. The result will help to establish a more complete chronology of the history of
Chichen Itza.
45. X-Ray Photoelectron Spectroscopy Studies of the X-Ray Induced
Degradation of Ancient Pigments
Enrico Ciliberto, Giuseppe Spoto*
*Dipartimento di Scienze Chimiche, Università di Catania, Viale A. Doria 6, 95125 Catania (Italy)
X-rays constitute an important tool for studying works of art. X-ray radiography, xeroradiography and other Xray imaging techniques provide options for a so-called non-destructive evaluation of works of art. Moreover,
analytical information is often obtained by in situ operating XRF spectrometers. All these methods have been
used on a variety of archaeological and artistic objects including painted artefacts.
In the present work the authors have studied the effects of X-rays on some important organic pigments in use
since the time of ancient civilisation. Four different pigments have been considered in particular: i.e. madder
lake, cochineal lake, alizarin lake and yellow saffron. All the pigments studied have been prepared following
ancient original formulae from natural dyestuffs extracted from plants and insects with the exception of the
alizarin lake prepared using commercial sources.
X-ray photoelectron spectroscopy (XPS) has been used to study the compositional alterations suffered by the
pigments after exposition under a standard X-ray source. The analytical technique used allowed the authors to
identify different levels of alteration in the irradiated pigments because the XPS sensitivity and acquisition rate
appeared to be consistent with the evolution of the modifications studied. Qualitative and quantitative
evaluation of the XPS spectral modifications provided some chemical information about the decomposition
studied.

Archaeological finds are generally studied by means of non-destructive analytical techniques. However, these
techniques prevalently provide information concerning the surface's state of the material. Metallographic
investigations on microsamples allow to get a complete archaeometric characterization of metallic artefacts.
The aim of this work was to study five finds made of gold alloy: a complete neckring found at "Bingia 'e Monti"
(Gonnostramatza, dated about 2000 B.C.) during archaeological surveys, a decorated lamina fragment found in
the Pirosa cave at Su Benatzu-Santadi (dated between Cypriot Late Bronze Age and Iron Age) and three
diadems, in which 'ox-hide' copper ingots of the Late Bronze Age are impressed, coming from a judicial
attachment happened in Santadi. To obtain surface analyses an optical stereomicroscope and a scanning
electron microscope + EDS were employed. Finds' surfaces are constituted by gold-silver-copper alloys, about
80% Au, 17% Ag, and 3% Cu regarding the four laminae and 51 % Au, 45 % Ag and 4 % Cu regarding the
neckring. In all cases, the surface patina is richer in gold than the bulk. Iso-oriented, thin lines are visible at the
microscope, probably due to a polishing with a cloth or a soft hide and some natural abrasive. The surface of
Santadi objects shows the presence of inorganic small particles inserted in the metal, probably deriving from the
soil in which the laminae were buried. Metallographic structures of Santadi fragment and of one diadems do not
show any intergranular corrosion. Su Benatzu find has got 127 1 13 Kg/mm2 of microhardness Vickers, and the
diadem 91 1 10 Kg/mm2. The scattering of these values is probably due to differences in the hammering and in
their chemical composition.

47. Isotope fingerprinting of ancient tin
Robin Clayton, Noel H. Gale, Zofia Stos-Gale
Isotrace Laboratory, University of Oxford, UK
The sources of tin in the Late Bronze Age (LBA) remain a significant unresolved problem in eastern
Mediterranean and Aegean archaeology. Muhly (1985) has written: "It is remarkable that, after twenty years of
intensive scholarly investigation and fieldwork, we still have no hard evidence regarding the sources of tin
being exploited by the numerous and widespread bronze industries of antiquity"; twelve years later the situation
remains unchanged. Lead isotopic methods have successfully identified the provenance of various metals (Pb,
Cu, Ag) used in ancient metallurgical processes of the region, thereby elucidating prehistoric trading routes and
aspects of LBA economic history and the peoples involved. Identification of the pathways of tin into LBA
civilisations using Pb isotopes from likely source ores is complicated by the multistage nature of the leads
involved, in contrast for example to the relative success experienced in matching copper based metals and
artefacts with various locations in the Cypriot massive sulphide ores, which contain lead of rather simpler
geological history (Stos-Gale et al. 1987).
A Leverhulme Trust funded research project into these questions in Oxford is based primarily on a two part
investigation of the isotopic composition of ancient tin ingots and of tin ores from various mineralisations. One
component relies on the measurement of lead isotope ratios in pure tin ingots, mostly from the Late Bronze Age
shipwreck of Uluburun (Kas) excavated off the Turkish coast by INA Texas, and comparing them with the lead
isotope characteristics of cassiterites from various European occurrences. The second part will include analyses
of the tin isotope composition of the same samples, and of tin extracted from prehistoric bronzes from Minoan,
Mycenaean, Cycladic and Cypriot archaeological sites. Preliminary, medium precision, analyses of the isotopic
composition of tin extracted from such bronzes (Gale 1997) has shown that the large changes in isotopic
composition predicted by Budd and Pollard to arise from melting and other anthropogenic processes do not
exist. Exploratory high precision work by Begemann shows, however, that there is a measurable difference of
tin isotopic composition for tin extracted from bronzes on the one hand from central Europe and on the other
hand for bronzes from the near and middle East. At this stage of research the observed dichotomy of tin isotopic
composition might indicate the use of different tin sources in these different regions, but the evidence does not
at present allow this to be a certain inference.
We will discuss the results obtained so far in Oxford. The methodology of the analytical procedures developed
for the project will be described, and lead isotope compositions measured for Bronze Age tin ingots from
various parts of the Mediterranean will be presented in comparison with those of cassiterites. The scope of the
proposed work bears not only on archaeological science but also on the application of an untested isotopic
system to ore geochemistry.

Across the field of ancient biomolecules lie gaps of credibility which mark boundaries between disciplines.
Protein survive for decades in forensic science, survival, while archaeological ‘proteins’ can survive for
millennia; palaeontological ‘protein’ however, seems to be a much more robust material altogether, and claims
for the immunological detection of fossil proteins span the Phanerozoic. Over a number of years we have been
investigating the survival of bone proteins, both in the laboratory and field.
The fate of proteins is strongly related to their size, structure and composition. Large helical molecules, such as
DNA and collagen, melt and albumin denatures whereas osteocalcin, which is small and binds strongly to the
mineral surface, is very robust. Predictions based upon high temperature experiments show that only osteocalcin
will survive into deep (geological) time.
If, then, osteocalcin has the potential to survive, is it the solution to the problem of radiocarbon dating highly
degraded bone or as an alternative to collagen for age at death determinations? Examination of the fate of
biopolymers in bones from a Neolithic site at Bercy offers an alternative view, since the diagenetic loss of these
molecules did not to follow the paths predicted by our experiments. Osteocalcin survived well when the
integrity of the mineral had been maintained, as did collagen.
49. Techno-typological and functional analysis of the lithic industry of the
Copper Age site Le Cerquete-Fianello (Maccarese, Rome)

sapienza", Roma
**Istituto Italiano di Paleontologia Umana
The lithic industry recovered at the Copper Age site of Maccarese-Fianello has been subjected to technotypological study and functional analysis, the results of which are here reported. This industry is mainly
composed of flakes and almost entirely obtained from flint cores. Side-scrapers and denticulates are the most
common tools, as well as flakes with use retouch and choppers, while bifacial tools, as arrowheads and daggers,
represent a smaller percentage.
The main interest in the study of the Maccarese-Fianello lithic industry rises from the scarce knowledge of
similar assemblages belonging to Rinaldone settlements. The study of the industry provides several interesting
developments: the study of the raw material origins, the technological analysis aiming to reconstruct the
"chaines opératoires" adopted for the production of the artifacts. Moreover, thanks to stereomicroscope and
metallographic microscope scanning, the detection of macro- and micro-wears allows the identification of the
tools function, both for the actions and for the materials. The microscope determination of the exploited edges
of tools is accompanied by the consideration of their morphological features (thickness, contour, section), which
are tightly connected to their function.
50. Archaeometrical studies on ancient glassy materials and obsidians using
Bucharest Cyclotron
Bogdan Constantinescu
Cyclotron Laboratory, Institute of Atomic Physics, PO BOX MG-6, Bucharest, Romania
The analyses of source materials combined with analyses of archaeological objects could distinguish from
pieces produced in different regions. This is the case of obsidians. Chemical differences that occur during
preparation of materials will affect the elemental composition and could be used for the identification of
technologies and workshops involved. This is the case of glass objects. We analysed obsidians samples (objects
and minerals) from north-west region of Transylvania, Byzantine bracelets pieces (10th-12th centuries) from
Dobroudja and feudal (17th-18th centuries) domestic glassy objects from Bucharest area. Three methods were
used: in air PIXE, XRF and FNAA (especially for light elements: Na, Mg, Al, Si). For in air PIXE, 3-5 MeV
proton beam obtained from 6.5 MeV Cyclotron nominal regime protons extracted into air through 20 mm
aluminium foil strikes the sample after 8-10 cm. X-rays were detected through reflection, using a horizontal
40
Archaeometry '98, Budapest
HPGe detector. XRF measurements were done with a spectrometer consisting of 30 mCi 241Am annular
gamma-source, a vertical Si(Li) detector and a conventional electronic chain. To produce fast neutrons,
deuterons, accelerated up to 13 MeV bombarded a thick (166.5 mg/cm2) Be target placed at 20 against the
incident beam (up to 20 mA). The absolute intensity flux on free air, at 10 cm behind the Be target was
1.824108 n/cm2WmC, with a neutron average energy of 5.24 MeV at 0. For obsidian identification of
geological sources for the analysed objects is presented (e.g. Bocsa-Salaj, Zam, Calinesti-Hurca). A typical
obsidian composition for relevant elements is: Fe: 2.1%, Mn: 0.15%, Ti: 0.1%; Rb: 350 ppm, Ba: 2100 ppm,
La: 50 ppm, Ce: 150 ppm, Nd: 60 ppm. For the Byzantine bracelets pieces, colorants (Mn, Fe, Cu, Zn, Sn, Sb,
Pb) and opacifiers (Sn, Sb, Pb) were determined and a classification of the objects was done. A typical
composition is: SiO2: 70.6%, Al2O3: 1.8%, MgO: 0.9%, Na2O: 8.4%, CaO: 2%, K2O: 3.9%, MnO: 0.5%, Fe2O3:
6.1%, CuO: 0.8%, PbO: 7.6%, Zr: 700 ppm, SnO: 0.9%; BaO: 0.3%, Ce: 150 ppm, La: 60 ppm, Nd: 50 ppm.
For feudal objects, a provenance identification based on main colorant (Ti, Mn or Fe) and opacifier (As) was
effectued.
51. Analysis of some Ancient and Middle Age coins by neutron activation
and X-ray fluorescence

Neutron activation method was applied to determine the Ag, Au and Cu elements contained in ancient Roman
and Greek coins or in Middle Age Hungarian coins (emitted by Bela II and Coloman), all from treasures
discovered in Transylvania, Romania.
The coins and standard samples were irradiated in the same conditions in a thermal neutron flux supplied by
Am-Be and Pu-Be isotopic sources system, providing 6,6*107 neutrons/sec. The nuclear reactions used to
analyse gold and silver are: 197Au (n, γ ) 198Au, 107Ag (n, γ ) 108Ag (T 1/2= 2.5 min) and 109Ag (n, γ ) 110Ag
(T1/2= 24 s).
The copper generates two β + active isotopes 64Cu and 62Cu. In both cases the spectra were recorded using NaI
(Tl) or Ge (Li) detectors. The method allows to determine the title of the silver alloy and to establish the fake or
underrairate coins.
By means of the impurity content we obtained the correlation diagrams that can offer useful information for the
study on the silver provenance. The coins were also classified according to the results obtained from X-ray
fluorescence analysis, by determining the ratios of several elements as Pb/Ag versus Fe/Cu, Pb/Fe versus Ag
content and Cu/Fe versus Ag content.
Significant clusters are obtained regarding the "print" of the elements composing the coin alloys. It is also to be
mentioned that the Middle Age coins contain gold up to 1,64% that is easy to be debuted in the Ag alloy. The
gold is also present in the silver ore but at that time their separation was not possible.
52. A Study of Later Chinese Metalwork.
Michael Cowell*, Susan La Niece* Jessica Rawson**
*British Museum
**Oxford University
This paper is concerned with the composition, construction and decoration of later (mostly post 15th century
AD) Buddhist Chinese metalwork in the British Museum Collections. It follows on from a study of Chinese
copper alloy coins (Bowman et al, 1989) which revealed changes in brass production from the 16th century.
The metalwork components of over 70 artefacts (figurines, vessels, bells etc.) have been analysed using atomic
absorption spectrophotometry (AAS) or inductively coupled plasma atomic emission spectrometry (ICPAES).
Decoration (gilding, inlays and pigments) were analysed by X-ray fluorescence (XRF) and X-ray diffraction
(XRD) and the construction of a selection of items was investigated by radiography.
The Chinese were comparatively late in adopting brass, or zinc-containing alloys, for this class of metalwork
even though they were familiar with its manufacture. In common with the coinage, brass was not extensively
41
Archaeometry '98, Budapest
used until the 16th century which contrast completely with Tibetan and Nepalese practice where it was
employed from the 12th century.
The alloys used for the Buddhist metalwork are more variable than those used for the contemporary coinage.
The zinc content is lower and gunmetal or mixed alloys are more frequent. In common with the coinage, the
later metalwork tends to have higher zinc contents. Whilst the use of brass is more likely from the 16th century
onwards, the amount of zinc or other alloying components does not assist with defining date of manufacture.
The trace element composition of the brasses, particularly the cadmium content which increases from the early
17th century, may be more useful in this respect.
Mercury, as opposed to leaf, gilding was more frequently found on artefacts with low lead contents. The range
of pigments found was similar to that on Tibetan figurines and included azurite, lazurite and hydrocerrusite. An
unusual pigment encountered on a late 14th century figurine was cobalt blue, possibly applied as a glass frit,
which has been reported previously in this context by Beguin et al (1982). The cobalt pigment in our example
contains associated elements which are compatible with the material imported into China prior to the mid. 15th
century and widely used to decorate porcelain.

Despite early claims of exceptional preservation of serum proteins on stone tools, recent criticisms have caused
some controversy in the subject. With a greater understanding of protein diagenesis on mineral surfaces, it is
thought that ceramics may provide a better environment for long term protein preservation due to there larger
surface areas and high porosity. This study aims to assess ceramic surfaces for their ability to bind and preserve
protein residues over archaeological time-scales. This involves screening tests (including pyrolysis mass
spectrometry, measurement of carbon isotope ratio and measurement of the carbon to nitrogen ratio) to
highlight the degree of molecular preservation and to select samples for further immunological analysis.
Particular emphasis is placed upon analysis of milk residues to ultimately shed light upon the use of disputed
early linear European milk pots Ceramics have been obtained from Iron Age (Easingwold, North Yorkshire,
UK) and ethnographic contexts. Simulated pots have also been constructed and used to cook a variety of foods
in order to investigate processes of organic accumulation in the vessel wall.
Amino acids have been detected at very low levels on archaeological pots identified using the screening
methodology. The use of simulated controls which have been artificially aged may tell us whether this is a
feature of archaeological pottery or whether conditions may arise which allow preservation of intact proteins. If
former is true, and proteins are less abundant on sherds than lipids, then it will be even harder to explain their
apparent preservation on stone tools.
54. New non-destructive analytical method in X ray fluorescence to trace

A non-destructive analytical method has been pointed out using X- ray fluorescence (XRF) aimed to determine
the provenance of finds made of lithic materials having a microcrystal or glasslike homogeneous matrix.
42
Archaeometry '98, Budapest
In the determination of the provenance a major limitation to the use of traditional chemical methods is due to
the impossibility to tamper the samples. In fact the most used techniques of analytical chemistry (X-ray
fluorescence, atomic absorbance) expect a preparatory phase that tampers the samples.
The non-destructive methods, like neutron activation, electron microscopy etc., show further and more
important limitations, like the high analytical cost (neutron activation) or the possibility to analyse only the most
abundant elements and not elements in traces, that are usually more significant than the major elements.
The starting point of the new method for the determination of the provenance of the obsidians has been the
individualization of a chemical-physical like quantity that could permit to compare, in a discriminating way, the
archaeological obsidians from those taken directly from the outcrop zone. The new X-ray fluorescence method
is based on the X-ray intensity ratio of two chemical elements, properly chosen, and simultaneously analysed. In
this case, it is possible to determine the origin of an unlimited number of samples without absolutely tampering
them.
Such methodology has given good results in the study of the provenance of the obsidians of west-central
Europe, Greece and Cappadocia (Turkey).
The method has been used for a first application in studying and determining the origin of the archaeological
obsidians but, as it seems by preliminary studies, may be also used in the determination of the provenance of
flints.
55. Experimental firing of clays using salt water
Michael Jost Von Der Crone, Marino Magetti
Institute of Mineralogy and Petrography, University, Pérolles, CH-1700 Fribourg (Switzerland)
Redfiring clays turn to a pale yellow or even white when prepared with saltwater. The bleaching is limited to
the surface and enters not more than about 1 mm in the sherd’s body.
In this study natural clays as well as synthetic clay mixtures were used. The fired samples have been studied by
XRD, HT-XRD, XRF, INA, Mössbauer spectroscopy, SEM and electron microprobe. During drying, the water
soluble NaCl, mineralogically halite, is enriched in the border of the ceramic product. The best bleaching is
achieved with addition of 1-1.5 wt. % NaCl to the dry CaO-rich natural clays resp. 2-3 wt. % to the dry CaOrich synthetic mixtures and firing temperatures in oxidizing conditions at 900-950 oC. After firing, the yellow to
whitish rim of these products is composed mainly of quartz, plagioclase and pyroxene as well as gehlenite
(depending on the CaO-content) with no hematite, contrasting to the red-coloured core of the samples which
contain much hematite, but less pyroxene and plagioclase. NaCl accelerates the mineral decomposition and
catalyzes the neo-formation of Ca-silicates, which incorporate the iron in their structure. In the initially haliterich border, gehlenite and pyroxene appear even at temperatures of 700 oC. After firing, the rims have lost K,
Na and Rb when compared to the cores.
56. Comparison of Probe Resistivity and Electromagnetic Methods for
Archaeological Prospection
Guy M. Cross
Fitch Laboratory, British School at Athens
A large scale electrical resistivity survey of Stymphalos, a Late Classical-Hellenistic town buried in lacustrine
sediments associated with seasonal flooding of Lake Stymphalia in the Greek Peloponnese (Papamarinopoulos,
et. all. 1989), has revealed much of the orthogonal plan of the ancient town and has played a central role in
preliminary interpretation and subsequent excavation of the site. However, recent uncertainty over land title
and access to overlying agricultural fields has diverted excavation activity away from the town center to the
acropolis and other areas of the site. Consequently further geophysical prospection is required to direct the
focus of these excavations and, concurrently, to establish a more complete picture of ancient Stymphalos.
To evaluate the potential of the electromagnetic induction method as an alternative to twin-probe resistivity
mapping, coincident, high-density surveys were conducted over a prominent rectangular anomaly, detected by
the original resistivity survey. The surveys were conducted at approximately the same time on consecutive days
under effectively the same environmental conditions (no intervening precipitation). In addition to assessing the
43
Archaeometry '98, Budapest
relative merits of the two methods for Phase II geophysical investigations at Stymphalos, the surveys provide an
illustrative comparison-contrast of the two prospection methods under ideal field conditions.
A 40 m by 40 m area was surveyed at a 0.25 m sample interval along east-west transects separated by 0.5 m.
Electromagnetic measurements of apparent electrical conductivity were acquired at ground level using a
Geonics EM-38 in vertical dipole mode (horizontal coplanar) with sensor boom oriented parallel to transect.
Coincident soil resistance measurements were acquired at medium sample rate (0.5 seconds/sample) using a
Geoscan Research RM-15, with 0.5 m twin-probe configuration.
44
Archaeometry '98, Budapest
In addition to comparing the clarity and resolution of resulting data images, consideration is given to data
acquisition rates, depth sensitivity and a statistical analysis of measurement precision. Findings indicate that
despite relatively infrequent use for archaeological prospection, the electromagnetic method can be an effective
and time efficient alternative to probe resistivity surveys.

57. High Resolution Seismic Imaging of Archaeological Remains: Field
Trials in Greece
G. M. Cross*, E. H. Williams**
*Department of Geophysics, University of British Columbia∗
**Department of Classics, University of British Columbia
The potential of the reflection seismic method to yield cross-sectional images of the subsurface was recognized
early on in the development of archaeological prospection. However, despite the mixed findings of reported
experiments, it was generally concluded by the early 1970s that seismic exploration techniques were of limited
value due to restricted resolution and the comparatively small-scale nature of archaeological remains (Tite,
1972; Aitken, 1974). Subsequent applications of acoustic techniques in connection with marine archaeology
were decidedly successful and prompted attempts to adapt these higher frequency "acoustic" techniques for use
on land. However, despite promising developments, the ill-fated reputation of seismic prospection has largely
endured (Scollar et al., 1990).
Meanwhile seismic reflection technology has been revolutionized in connection with recent developments in
environmental and groundwater geophysics and, in light of these developments, a research programme has been
underway at the University of British Columbia to reassess the potential of high-resolution reflection seismic
techniques for archaeological investigation (Cross, 1995). On the basis of a thorough theoretical review of
factors controlling seismic detection and resolution, this work led to the development and testing of a prototype
data acquisition system, combining "off the shelf" technology and special purpose instrumentation.
Experimental soundings acquired over a full-scale subsurface model demonstrated the capability of the system
to detect and image features on the scale of archaeological interest. In fact, a direct comparison between
seismic results and coincident 100 MHz ground penetrating radar soundings confirm that the seismic method is
capable of similar resolution.
Here we present the findings of preliminary field experiments conducted in connection with on-going
archaeological excavations at two sites in Greece. Although results are promising, field trials identified a
number of critical deficiencies. At Stymphalos in the Greek Peloponnese, where remains of the Late ClassicalHellenistic town are buried at shallow depth in lacustrine deposits associated with seasonal flooding of Lake
Stymphalia, direct arrivals constituted a restrictive source of interference, masking reflections-diffractions from
archaeological features. At a second site, Phalasarna, a maritime port of the fourth century B.C. on the northwest coast of Crete, the host soil is poorly sorted and highly consolidated. As a result, variations in sourcecoupling efficiency gave rise to substantial variability in wavelength characteristics, making identification of
45
Archaeometry '98, Budapest
coherent events difficult. System refinements, currently underway to address these limitations are discussed.
Despite pitfalls, results indicate that the method is viable and may have a significant future role in
archaeological prospection.

Animal remains identified during the excavations of the hilltop Temple of Montuhotep Sankhkara (Thoth Hill,
Thebes) included the mummified remains of a young heifer's leg. It was recovered from the north-western
foundation deposit and originated from the right thoracic limb of an animal that was approximately 2 years of
age.
Pieces of dry tissue (including skin and tendons) were removed from the palmar side of the metacarpal region.
Chemical analyses of the 4000 years old sample revealed a remarkably good preservation of proteins and high
concentrations of sodium. The amounts of ammonia and free amino acids, indicators of protein decomposition
were low. Of the amino acids, sulphur containing cystine and remains of keratin were barely detectable. Cystine
is one of the least stable amino acids, and as such is known to have decomposed even in significantly younger
samples of wool.
While soft tissue preservation in the dried cattle leg was most probably due to spontaneous mummification in
the windy and arid hilltop environment, the meat's pre-depositional treatment with salt cannot be excluded.

After reviewing previous attempts to use the extent of amino acid racemization (AAR) for the determination of
the age of archaeological samples containing proteins, we present our own approach. Before starting amino acid
racemization research, a new method was elaborated for protein hydrolysis with very low racemization of
amino acids. The hydrolysis was performed at high temperature (170 oC) for a short time (30 min) which caused
very low racemization compared to the original (110 oC, 24 h) method. Subsequently the D- and L-amino acid
content of fossil bone samples of known age (radiocarbon method) was determined by HPLC after precolumn
derivatization. Based on the half-lives of racemization obtained and plotting the D/L ratio as a function of time
for various amino acids, calibration curves were obtained which can be used for the age determination of fossil
bone samples in the range of 2000-500.000 years. Another method is presented for the determination of age of
textiles in the range of 100-1800 years. This method is based on the determination by amino acid analyser of
the age-dependent alteration of amino acid composition of proteins. Cystine, methionine and tyrosine content
decreased, while cysteic acid content increased with age. Prediction equations were developed as linear
regressions of age of wool based on cysteic acid, cystine and tyrosine content.

60. The homogeneity-examination of plano-convex ingots using EPMA
Zoltán Czajlik - Kamilla G.Solymos
Loránd Eötvös University, Budapest
As was noticed in previous publications1, the examination of samples taken from the surface-zone of the planoconvex ingots (generally from a single point) is open to strong criticism. The focus of criticism has been the
dubious homogeneity of plano-convex ingots. It is questionable, whether even a very detailed examination of a
small (a few cubic-millimeter) sample is representative of the ingot?
The plano-convex ingot fragments from the Hungarian-French excavations at Velem were restored with nontraditional methods2. This technology, that uses no chemicals and stabilizing-materials, is preferred not only
from the viewpoint of further examinations, but also shows the layered structure of plano-convex ingots. This
structure was formerly noticed only in some cases3. The layers that became visible by the naked eye are as
follows (listed from the convex to the flat side):
- heavily porous layer with traces of gas bubbles
- compact, thick, homogeneous layer
- dark gray layer, whose cleaned surface is rapidly covered by sulphure excretions
- thick, homogeneous, compact layer
This structure can be followed especially well on the plano-convex ingot No.V93.F4, in the other cases the
layer with strong porosity on the convex side could not be identified. This ingot was previously analyzed by
using EPMA, but only in the surface-zone. The phases, indicated in that 1995 study may be summarized as
follows:
- pure copper phase, within which
a lead-rich sub-phase with some antimony and copper as well as
silver containing inclusions were found.
New analyses were aimed at testing the inhomogeneity of the ingot and analyzing the composition of the layers
noticed macroscopically. For the purposes of these examinations the ingot was cut to expose its cross-section,
polished and analyzed by both microscopically and by using EPMA in the entire cross-section.
Results
Proceeding from the convex to the flat side, grosso modo the same layers could be distinguished as had been
established by macroscopic observation:
- compact layer formed by the lead- and copper phases, especially rich in lead along the convex border where
sporadic quartz-inclusions also occur. These latter occur in the outermost, porous surface-zone. (A)
- a dark gray layer that contains mainly copper-sulphide, close to the composition of covelline (Cu2S). This
composition corresponds to copper-sulphide-phases, generally found during previous analyses. It is only this
layer that does not display "artificial” patterning (B)
- The thick layer on the flat side, similarly to layer A, also contains metallic copper and lead phases (C).
Within the macroscopically compact layers, the percentage of the lead is higher along the border. Presumably,
this lead is not of natural origins, but is very likely indicative of the use of lead-oxides (as an alloying ballast
material).
Summary
Total cross-section EPMA-analysis has shown, that strata within "layered" ingots are more or less
inhomogeneous. On the basis of previous and new analyses it is obvious, that the small samples, taken from the
surface-zone, or from the inside of the ingot show but a small difference in composition. This difference,
however, usually does not modify the most important conclusions relevant to geological (origins) and
technological (production) interpretations.
Our examinations confirmed the impression, (previously tested at several points on the external surface
of the same ingot), that composition of elements usually does not differ within the same ingot, the percentage of
these elements, however, does.
Elements occurring in small quantities or as inclusions, as well as rare phases, may be absent in small samples
measuring only a few cubic millimeters. Ingots with layered structures and their inhomogeneity point to the
importance of cleaning the surface sampled, and the careful selection of the point to be sampled. It can also be
47
Archaeometry '98, Budapest
stated, that the ingots are not mixtures of metals, but semi-products with relatively stable percentile
compositions on the inside. Further examinations are needed to understand "layered" ingots, which occur
obviously more commonly than was thought

61. Polished stone between Neolithic and Bronze Age in Northern Italy

The authors present the status of the research carried out as a project of the Italian National Research Council
(CNR) for studying the circulation of prehistoric polished stone implements in Northern Italy.
The studied period spans from early Neolithic to Bronze Age. In the last decade petroarchaeometric knowledge
on polished stone has made some remarkable progress, thanks to systematic studies of several important
collections. A few lithologies proved to be dominant, in particular alpine eclogites and jades (Na-pyroxenites).
Most outcrops of these rocks are located in the Western Alps, at the Italian watershed. However the prehistoric
populations seem to have preferred secondary, alluvial deposits and Oligocene conglomerates, where the above
mentioned lithotypes are available in the form of natural pebbles and cobbles. Possible production areas and
workshops have been localised in some places in southern Piedmont, Liguria and south-western Lombardy.
Petroarchaeometric analyses (microscopic examination, thin sections, XRD, more occasionally chemical -XRF,
AAS - and microprobe analyses) have been conducted so far on nearly 1000 objects, coming from several
prehistoric sites of northern Italy. These results are presented together with a comparative analysis of the
various assemblages. Some trends regarding the use of Neolithic-to-Bronze Age stone resources and circulation
in Northern Italy and Europe can already be suggested.
- a) The production of polished stone tools in Northern Italy seems dominantly dependent upon western sources.
Besides prevalent eclogites and jades, serpentinites and, more occasionally, omphacite schists and metabasalts,
glaucophane schists, retromorphic green schists, chlorite schists, nephrites, etc. can be mentioned.
- b) Jades and eclogites have been widely exported to Europe (Britain, France, Rhine region, Austria, Moravia,
etc.) as normal and ceremonial axes. A comparison on a European scale deserves attention.
- c) The more distant sites from the raw-material sources in north-eastern Italy show a remarkable contribution
of local lithologies (in particular Triassic acid tufites), as well as a modest contribution from Transalpine
sources of the Danubian-Carpathian areas (actinolite schists, andesites-dacites, silexites).
- d) A significant change of lithic refurnishment to the sites can be observed between the late Neolithic and the
Copper Age, when basaltic (l.s.) rocks from the Appennines (Emilia), or serpentinites and basic rocks from the
Eastern Alps and/or Dinarides (Trieste region) become dominant.
- e) Different lithologies seem to be selected for the different categories of polished stone tools, i.e. cuttingedged tools (axes, adzes, chisels) and ceremonial axes vs hammer-axes, vs bracelets and pendants, because of
either functional reasons connected with the rock properties, or diachronic change in lithic exploitation.

Different experimental techniques were researched in purpose of precious and semiprecious stones
authentication. A first method was the determination of the respective mineral density with the hydrostatic
balance. Thus rubies and sapphires were determined and strasses excluded which were presented as zircon. The
analysis by X-ray fluorescence method was applied for the Cu determination from turquoise and for Fe and Mn
from obsidian. At this last one also origin studies were made. Because of the necessity of checking the
crystallographic structure analyses were made by X-ray diffraction on amethysts, lapis-lazuli’s, sapphires and
rubies, obtaining characteristically diffraction spectra. Net constants were calculated and the crystalline
structure determined (for example a quartz type alpha, presented as false topaz). Also some images of
diffraction were obtained by Lane method on photographic plate, in purpose of the fake distinguishing from
glass, from the authentical crystals. The rubies were researched by RPE, obtaining information about the Cr3+
ion, which gives the red colour and also about the hexaedrical groups from the Al2O3 crystal, which is the host
net.

The "stamp" method applied to put into evidence impurity elements appearing beside the major chemical
components of the ores offers the possibility to identify their provenance sources. The aim of this paper is to
establish the provenance sources of prehistoric obsidian found in archaeology sites from Romania.
The discrimination parameter may be computed as function of the element content. In this diagram the points
corresponding to the obtained data are disposed in clusters which allow to localise the provenance source of the
investigated samples. The investigated obsidian samples (from Fratelia and Parta near Timisoara and Iclod near
Cluj) together with two obsidian samples arising from known sources (Melos and Sardinia) were activated by
neutron irradiation in the nuclear reactor and analysed by gamma spectroscopy.
The samples are also investigated by EPR and XRF methods in order to obtain more information about the
obsidians characteristics and to confirm their provenance sources.
Our results lead to the conclusion that the Neolithic obsidian samples are arising from the Carpathian group
(Slovakia) denoting trade or economic exchange relations along the rivers Tisa-Timis and Tisa-Somes, having
in view that the obsidian samples are found more hundred kilometres far from the sources. According to the
Carpathian group classification in two types C (1) and C(2) corresponding to the major elements and according
to our earlier results the provenance area for the analysed samples is Cejkov and Kasov (Slovakia).
64. Distinction of Pottery Workshops - A Comparison of Experimental and
Archaeological Material

The tools mostly used to distinguish local and imported pottery are chemical analysis and thin section studies.
When the raw materials had been the same, e.g. because of a geologically uniform region, we may not find any
significant differences in chemical composition nor in the kind of temper. Of course, this does not prove that
there had been only one workshop. In such cases, possible differences in the technological process of pottery
making can be used to distinguish workshops. In our presentation, mainly the preparation of the body and firing
will be regarded. A large variation of firing temperatures applied in a single workshop may be caused by the
inhomogeneous distribution of temperatures within the kiln and other accidental influences. Also, to obtain a
well fired product, a given ceramic body should be fired within its characteristic range of temperatures which
will be the same in different workshops in case the same raw material was used. The other important process,
the time-consuming preparation of the body, may be less susceptible to accidental deviations and therefore
better suited to identify different workshops. The final products then are grouped according to their ceramic
properties which, given the same raw material and the same formula, depend on the way of how the body was
prepared to make it homogeneous and to work out air. Determination of the ceramic properties (apparent
density, open porosity and water absorption) of original and refired sherds, as well as thin section studies and
49
Archaeometry '98, Budapest
chemical analysis by WD-XRF, were used to distinguish groups. Interpretation is based on experiments with
calcareous and non-calcareous potter's clays prepared in different ways and fired at various temperatures. Fortyfive samples of Roman Sigillata from excavations of the kiln area in Rheinzabern, Germany, as a test case,
yielded technological groups which correspond to archaeologically distinguishable workshops.

Excavations by Erik Nielsen and co-workers at the Etruscan site of Poggio Civitate (Murlo), south of Siena,
yielded evidence for the production of tiles, architectural terracotta and various types of pottery during a limited
occupation period between 7th and 6th cent.B.C. Including the ceramic material used for crucibles and tuyeres
for bronze casting, there is a large variety of ceramic fabrics. The analysis of the finds and a survey for local
raw materials aimed to answer the question which materials had been selected and how they had been prepared
for the very distinct purposes. The main emphasis, therefore, was in determining the technological properties of
the materials. Experimental firing of clays and refiring of artefacts at various temperatures was done and the
changes in ceramic properties analysed. Thermal analysis, XRF, XRD and thin section studies showed that a
very special local material, deriving from ophiolithic rocks, was used for tiles, coarse and fine wares, as well as
for crucibles and tuyeres. This raw material, found at a distance of a few kilometres from the site, mainly
consists of a weathered gabbro sufficiently plastic because of a high smectite content. This material is more
refractory than all other local clays (therefore, it was used in a workshop on experimental bronze casting,
organised in 1995 in Murlo by Edilberto Formigli). The largely available local calcareous clays had not been
used at the site. Most buchero vessels, as the most typical Etruscan fine ware, are from non-calcareous clays and
not locally made. It is shown how in archaeoceramological studies experiments and technological analysis adds
significant information to chemical and thin section analysis.
66. Ferro-Chalcolithic phase in West Bengal
Asok Datta
Dept. of Archaeology Calcutta University, 51/2 Hazra Road, 700019 Calcutta, India
The entire proto-historic phase in West Bengal has been earlier designated as Chalcolithic culture. But in view
of the discovery of large number of iron objects from different excavated Chalcolithic sites, the terminology
was modified as Ferro-Chalcolithic. This nomenclature too does not seem to convey a meaningful proposition
for the historical growth in West Bengal. But for the present purpose, we shall continue to use the term FerroChalcolithic.
The Proto-historic culture in West-Bengal roughly spans over one thousand years. Iron tools have been found
from different levels of this Proto-historic phase indicating a fair amount of knowledge in iron metallurgy. The
tools comprise spearheads, points, daggers, chisels, axes, pegs, nails, rods, sword-blades, sickle, slags, ores, etc.
Chemical and metallographic studies show progressive changes in technology over time. The development of
this technology in West Bengal can be traced in three different stages - each stage being characterised by its
own identities. In the final stage, the hardening and quenching methods were observed in an iron sickle from
Pandurajardhibi which is recorded as the earliest evidence of this technology in India. It appears that the
presence of a strong iron technology in the proto-historic phase was largely instrumental for bringing about a
major change in economy during 3rd/4th cent. B.C. in lower Bengal which marks the beginning of historical
period in West Bengal.
67. Carbon-14, tree rings, ice cores and chronology

The paper will discuss the impact of Carbon 14 on Archaeology, then the effect of the corrections. Next, the
evolution of the mature tree ring chronologies will be mentioned, and finally evidence from the Polar Ice Cores
that has given precise dates for major volcanic events in the Second Millennium B.C. will be discussed.
For Archaeological Chronology the key date is that of the eruption of the island of Thera (Santorini) in the
Aegean which covered diagnostic pottery on which, until now, the chronological system of the whole of the
Near East, Egypt, Mesopotamia, and the Aegean has been based.
The paper will discuss briefly these synchronisms, and the great gaps in the present system. It will criticise the
"subjective glee" with which archaeologists have uncritically accepted the date of 1626 B.C. for the Thera
eruption, and propose a different chronology based on the Ice Core and Tree Ring data.
The author is an impure scientist (geologist, metallurgist, and mining engineer) and has been an archaeologist
for the last thirty years, and considers that the purer scientists involved in Archaeometry should know what the
archaeological problems are.

The state of preservation of skeletal remains is a concern for archaeological research as poor preservation often
makes them unsuitable for physical and chemical analysis. It is important therefore to be able to evaluate
systematically the state of preservation of the materials to be studied.
This paper reports the initial results of a research that applies several analytical methods to the study of the
organic and inorganic fractions of bone. Total, deproteinized and demineralized archaeological human bone of
different states of preservation as well as fresh bone were used to evaluate the feasibility of using Fourier
Transform Raman Spectroscopy (FTRS) for the characterization of archaeological bone. As Fourier Transform
Infrared spectroscopy (FTIR) has been widely used to study bone apatites, a comparison of FTRS and FTIR is
presented. Other methods of interest are discussed, including some mechanical properties of bone.
69. Application of Diatomological Analysis (Provenience) in Archaeological
Ceramics: an experimental approach
Guillermo De La Fuente
Escuela de Arqueología - Universidad Nacional de Catamarca - Argentina
Although diatom analysis has been used as an adjunct to archaeological enquiry for over 30 - 40 years, there
are very few publications exemplifying its use, and diatom results are often relegated to specialists appendices
in archaeological reports.
Provenience analysis of ceramic artifacts is a relatively new field of diatomology - archaeology interdisciplinary
research and it has a great potential for solving archaeological problems related with clay sourcing for ceramic
production in the past.
In this paper we present an overview of the main applications of diatomological analysis in archaeological
research emphasizing in the studies that focus in provenience analysis of archaeological ceramic artifacts
through out a study case from Chaschuil Region, Tinogasta, Catamarca Province, Argentina.
Some methodological and technical aspects of this research are discussed in order to evaluate the significance of
this archaeological bio-indicator for the study of (1) clays sources for ceramic production in the past, (2) local
versus non-local clays exploitation and (3) spatial mobility of ceramic artifacts.

The medieval glazed pottery in Anatolia contains a strong typology group in appearance as fine sgrafitto
decorated ceramics. In this study twenty such pottery pieces coming from Ephesus, Iznik and Korucutepe
archaeological sites have been investigated. The glazes of these pottery items are mostly yellow and green
colored with white slips.
The pottery samples have been analyzed to determine the properties of body, slip and glaze parts in terms of
raw materials composition, firing temperature and glaze characteristics.
Investigations were done by using optical microscopy, scanning electron microscopy coupled with energy
dispersive analyzer, Fourier transform infrared spectroscopy and X-ray diffraction analyses.
The results show that the pottery bodies have some vitrification. The state of vitrification have been discussed in
terms of iron, calcium and clay minerals content as well as firing temperature. The slips are mainly composed of
quartz and mica with low vitrification. The glazes are high lead glazes of above sixty percent content. The glaze
composition have been characterized in terms of mineral composition, homogeneity and colorants.

Antwerp, one of the largest ports of Europe in the beginning of the 16th century, was an important centre for the
manufacture and import of glassware and is especially known for its trade in Venetian and 'façon de Venise'
glass. Archaeological excavations have yielded a large number of glass finds, probably due to activities such as
the import and trade of glass objects and of raw materials as well as the local manufacture of glassware. Within
this extensive collection of finds an important number of Venetian and/or 'façon-de-Venise' glassware of
different shapes and types was encountered, some of which may have been imported, but of which the majority
is assumed to have been manufactured locally.
The aim of this work is to find out whether there was local production of these kinds of glass vessels in
Antwerp and how this local production can be distinguished from 'real' Venetian wares.
A representative set of about hundred glass vessels from different excavation sites in the centre of Antwerp was
selected for major element analysis by EPXMA (electron probe X-ray microanalysis) and their trace element
content was determined by means of SR-XRF (synchrotron radiation induced X-ray fluorescence analysis).
The analysis results were compared with compositional data of glass of well-known origin. Several
compositional groups are distinguished: one containing glass objects with a composition resembling Vitrum
Blanchum glass ('common' Venetian glass), several groups which show no resemblance to the other groups and
one group with a composition similar to cristallo glass (Venetian luxury glass). These compositional data will
finally be compared with the composition of 'façon-de-Venise' glass found in different locations of the Southern
Netherlands.

The weaving of luxury fabric is known to have been an active and important industry in Central Asia, Middle
East and around the Mediterranean sea. Nothing is known of the history of the textiles except that they were
preserved in European church treasuries or tombs. Attempts to sort out which 13th to 14th century textiles have
historically been woven, were made on the basis of styles and patterns. But this method has resulted in a
confusion of conflicting attributions because of the freedom with which motifs and patterns moved from one
part of the world to another along the trade routes linking the Mediterranean with China.
In addition to identifying criteria by which textiles can be distinguished, technical analysis have revealed
structural differences in the formation of the selvages, the combinations of fibres and the composition of metal
threads (1).
The metal threads found in these textiles consist most commonly of strips of animal substrate (membrane,
leather, parchment) that were silvered and/or gilded on one side, and either woven flat, or wound around a core
and then woven.
The animal organic substrate can be examined in order to specify the identity of the treated skins. Access to
ancient DNA provides the opportunity to study the genetic material of animal substrate and identify the species
used for the production of the strips. A molecular tool using mitochondrial l-rRNA is developed (2). The
sequence of the chosen fragment is suitable for differentiating cow, goat, sheep and pig (all domestic animals
possibly used for the substrate production). Assuming that the treated skins used for the manufacturing process
are related to the animal population of the geographic area, comparative studies can point out sufficient
evidence to propose a more precise place of production.

The observations of the metallographic structure of archaeological iron artefacts illuminate the working
processes used to obtain the objet, but cannot determine its reduction process (direct or indirect). To obtain this
information, it is useful to study the crystallisation of inclusions (impurities coming from the smelting and
working) that can give indication about old smelting processes.
The last progress in microanalysis with synchrotron radiation is offering new prospects in this area of research.
Thus we developed a new experimental method to collect a number of information about inclusions
composition and microstructure. We used synchrotron radiation focalised on few square micrometers by a
Bragg Fresnel Multilayer Lens (BFML) to set up a microdiffraction method coupled with micro X-ray
fluorescence (XRF). We complete this analyses by classical Energy Dispersive Spectrometry (EDS) coupled on
an Scanning Electronic Microscope (SEM).
We present here the first results of the analysis and comparison of the composition and phases of inclusions
entrapped in different archaeological artefacts representatives of the evolution of ironmaking from Gallo-roman
period to the 19th century. We also made analysis on iron samples coming from experimental smelting and
considered as References for the present results. This results shows that certain phases (especially containing
aluminium or phosphorus) appears only in particular processes and could be discriminant phases between direct
and indirect process.

74. Prehistoric and classical stone quarries (“mines”) in the Carpathian
Basin
Viola T. Dobosi, Katalin T. Biró
Hungarian National Museum, Budapest
Hungary is not very rich in mountainous areas composed of rocks with valuable physical and aesthetic qualities
for tool-making and / or building purposes. About 90% of the territory is covered by young terrestrial
sediments. In historical (and, prehistorical) periods, however, the Carpathian Basin formed closed economical
unit with very rich resources, both for agriculture and mining. Cultural entities considered by most periods
comprised extension in the framework of the Carpathian Basin, often transsected by the river Danube - notably,
also in antiquity (“Pannonia” versus “Barbaricum”). Therefore, relevant petroarchaeological studies must be set
in this framework. This aspect is realised by our contemporary prehistoric raw material comparative collection
(BIRÓ-DOBOSI 1991) and the former large catalogue (and collection) of Zoltán SCHAFARZIK (1904).
Raw material exploitation and mining is documented in Hungary since the turn of the Middle / Upper
Palaeolithic period. The most typical object of prehistoric mining is different types of siliceous raw materials,
i.e., flint, chert etc., used for the production of chipped stone artefacts. Obsidian is also important for this
purpose, though - at least in Hungary - no traces of mining could be observed yet in the exploitation areas. Flint
mines tend to be in use mainly during the Neolithic period, though very important and complex mines are
known from the Bronze Age as well.
By the Late Neolithic, the first metal ore (typically, copper ore) mines appear. There are no direct proofs for
prehistoric ore mines in the Carpathian Basin. Indirect proofs, i.e., a very rich and authentic Copper Age and
local workshops on the settlements indicate the importance and possible existence of such mines.
The number and quality of sources concerning Roman quarries and mines is essentially increased compared to
prehistoric mining. These proofs can be divided into two parts: archaeological evidences like tools, traces of
exploitation and various stone objects - sculptures, memorial stones, building stones etc., as well as written
documents commemorating the high degree of organisation of mining activity.
The present day territory of Hungary is not specially rich in raw materials. Considered together with the other
territories of the Carpathian Basin, it is an important economical unit. For prehistoric trade as well as raw
material supply and trade in antiquities, this territory should be emphatically considered.

Non-flint stone tools of different archaeological sites of the Atlantic Band of Cádiz province (SSW Spain), are
studied. These sites have chronologies between Lower Palaeolithic and Chalcolithic (III millennium B.C). They
are always coastal or interior open air enclaves.
Preliminary results of our mineralogical and petrological studies (X-Ray diffraction, optical microscopy and
macroscopic characterization) of these materials were compared to the petrological characteristics of some
samples from geological units of this area, with the aim to determine the authoctonous or alloctonous character
of these, and their possible source areas. Our results show a predominance of two lithologies: dolerites and
sandstones. Both have a local procedence and they are non-regularly distributed at the prehistoric sites. Some
other lithologic types appear, in general with an alloctonous procedence, like exotic lithic materials as variscite
green-beads or cinnabar, present in dolmens of the Cádiz province, and with raw areas distant at least several
hundreds of kilometers of these sites.
Statistic balance between lithologic character, type and/or utility of stone tools, was made, showing a clear
relationship between many lithologies and use. In this sense, we are shown a predominance of lithologies of
54
Archaeometry '98, Budapest
high resistance to the abrasion and low fragility (good mechanical behaviour). From these type of rocks,
dolerites are predominte, and they are specially used to make axes. Other similar materials have an alloctonous
origin and a minor utilization range, as amphibolite, sillimanite and jasper.
From these studies we can obtain interesting conclusions about the production mode, the life, the raw materials,
55
Archaeometry '98, Budapest
the source areas of these and the technological level of the hunters-gatherers, tribal and classist societies that
lived at this geographical area.

Cádiz province, placed at SW Spain is a very important archaeological zone, with vestiges from Lower
Palaeolithic to the present. Its strategic location (north border of Gibraltar Strait) made of this an important
geopolitical center at different moments of its history, as occurred during the Roman Empire, in which it was
an important center of commerce. Different towns are developed at this time, well communicated between them
by roman causeways, and joining agricultural and mineral production centers, with the marine harbor
installations and fishing factories.
One of these towns was Assido (nowadays Medina-Sidonia), an important agricultural center on the Cádiz
countryside, placed in a strategic elevation, and communicated by the causeway between Hispalis (Sevilla) and
Baelo (Bolonia). Different Roman constructions (water conduction, sewage system, etc.) were recently
excavated, and dated at first century A.D. (S. Montañés, 1993).
Different samples of wall painting, which appear as filling material of one of these constructions (Espíritu Santo
Street, at the Medina Sidonia village), are studied. They present different pictoric styles, with human and animal
representations and floral / geometric motives.
Analytical techniques as X-ray diffraction, optical and electronic scanning microscopy, energy dispersive
spectrometry and infrared spectrometry are utilised, identifying as principal pigments, many minerals and
synthetic materials. In these painting samples, we have identified at least seven different colours. Many other
observed painting tones, were obtained by mixtures between them. These colours are: white, black, red, ochre,
yellow-ochre, green and blue.
White colour pigment is mainly made of calcite; black colour paint, of lamp-black; red of hematite; ochre of
goethite, yellow-ochre of goethite-hematite mixtures; green of celadonite and blue of a synthetic compound, the
Egyptian Blue, obtained from the friture process of calcite, quartz and copper rich residues. Mineral
components of painting are compared with possible source areas of raw materials and with other Roman
archaeological sites of SW Spain area.
The compositional and textural features of plaster were studied by optical and scanning electron microscopy,
and X-ray diffraction. At least four differentiated layers appear at this plaster. Paint is deposited on an arriccio,
a finishing coat usually made with marble dust. The intonaco was made by two or three successive layers in
which sand grains are the principal component, in general with quartz, K-feldspar, plagioclases and rock
fragments. Third and/or fourth layers also present brick fragments and a high porosity. For the first time,
exoscopic characterization of quartz grains of the plaster and of different sand samples proceeding from
different geological sources suitable as raw material, are compared to dilucidate the raw area of this material,
employed by the roman craftsman.

77. Defining significance:Problems in dealing with Cu-As and Cu-As-Sn
alloys
Roger C.P. Doonan
Ancient Monuments Laboratory, English Heritage 23 Savile Row, London
Although copper-arsenic alloys are an almost ubiquitous phenomenon in the world's metallurgical traditions, it
still remains a contentious point as to the level at which arsenic should be considered a useful addition to the
alloy. Whilst some scholars have arbitrarily drawn a boundary at 1% arsenic, below which arsenic is thought to
have no significant effect on the alloys properties, other scholars have conducted experiments to ascertain at
what level arsenic creates significant differences in mechanical properties, such as hardness, and tensile
strength. Other more anthropocentric studies have concentrated on defining useful levels based on other
properties more perceivable to humans such as colour and even smell.
This paper addresses aspects of Cu-As alloys which have hitherto not received appropriate attention. Virtually
all studies have focused on the arsenic content and properties of the finished artefact and the relationship to its
perceived function. Such teleological studies have erroneously ignored the major events in the sequence
responsible for artefact production. The introduction of the concept of the "chaine operatoire" reminds the
investigator that the properties of an alloy should be considered not only in terms of the finished artefact but
also in terms of the melting regime, the casting regime, and the working regime.
Results of laboratory-based experiments are presented which indicate that arsenic concentrations significantly
lower than those that could be thought of as useful for enhancement of mechanical properties or colour, offer
advantages in terms of producing a sound casting-specifically by avoiding the unwanted formation of copper
oxides. High arsenic values are often reduced during melting and casting to below what is often considered
useful. This sacrificing of arsenic as a deoxidiser means that low or residual arsenic levels can sometimes be
thought of as ghosts of former higher levels and should therefore not always be judged as inconsequential.
Although examples of Cu-As-Sn alloys have also been documented in prehistory, the general trend seems that
arsenic and tin were kept separate. Some scholars have taken this to be evidence that ancient smiths recognised
the different alloys and intentionally manipulated them. This has been assumed without any detailed
examination of the alloys themselves. The results of laboratory experiments are presented here which elucidate
the complex interactions between these three elements and the implications for the intentionality of Cu-As
alloys are discussed.
78. The Use of Stable Carbon Isotopes in the Identification of Dairy
Products in Archaeological Ceramics

Information on vessel use, food consumption patterns and animal exploitation plays an important role in the
reconstruction of the economy, status and organisation of an archaeological site. Secondary evidence is often
the most commonly available source of information, for example, our knowledge of the importance of dairying
in antiquity has been gleaned predominantly from kill patterns1 due to the lack of direct evidence. In the absence
of faunal remains, however, a reliable and robust method of deriving information on animal exploitation and, in
particular, dairying has remained elusive until now.
We have shown that variations in the stable carbon isotope compositions (δ13C values) of subcutaneous fats
from ruminant (ovine and bovine) and non-ruminant (porcine) animals2 provide a means of distinguishing
between the remnant fats preserved as residues in archaeological pottery. Further work has shown that clear
distinction can be drawn between the stable carbon isotope characteristics of milk fat and adipose fat from
ruminant animals, based on fundamental biochemical differences in their formation. The variations are based
upon differences in the δ13C value of the C18:0 fatty acid and are essentially due to routing and energy balance
in the body during lactation3.
Here we present the results of compound specific stable carbon isotope analyses, obtained by GC-C-IRMS, and
compositional data for fat extracts from archaeological pottery assemblages in the UK. Significantly, the data
57
Archaeometry '98, Budapest
indicate that different sites exhibit distinct patterns of resource utilisation in association with ceramic vessels.
In this work the potential for the use of stable carbon isotopes in the identification of degraded fats is realised,
with the most significant achievement being the identification of dairy products which are otherwise
undetectable.

Reinach/Switzerland

50 samples from a Carolingian pottery workshop were studied.
1) The kiln is built of a CaO-poor clay (n=4) with a very fine-grained temper (2 - 8 Vol. %).
2) 30 sherds from both kilns form a homogeneous, CaO-poor reference group. They are richer in granitic
temper (14 - 38 Vol %) than the kiln structures. These temper fragments have been intentionally added. The
original clay is similar, but not exactly the same as the one used for the kiln structures. One sherd has a calcitic
temper.
3) 10 pottery fragments from the building are very heterogeneous in both the chemical and mineralogical
composition. The granulometry of the granitic, artificially introduced temper (16 - 25 Vol. %) shows a wide
variation. The original clays are different from the clays of 1) and 2).
4) The pottery was fired under weak reducing conditions at temperatures in the range of 650-850 oC.
5) From five local clays, only one is CaO-poor and matches the composition of 1) and 2).
80. Metallographic Examination of Sand Cast Copper and Bronze
Mark Eccleston, B.S. Ottaway, Maria Scordara, Scott Seibel, Nathaniel Stevenson
Dept. of Archaeology & Prehistory, University of Sheffield, UK
A brief overview of the archaeological evidence, or the lack of it, for the use of sand moulds for casting copper
and copper-based artefacts and ingots in prehistory will be given. Archaeological evidence from Central
Europe, Greece and the Aegean, Asia Minor, the Levant, Egypt and South East Asia will be incorporated into
the study. It will be suggested that the use of sand moulds, rather than clay, stone or metal moulds was much
more common during the Chalcolithic and Early Bronze Age than hitherto accepted.
Experimental castings will be carried out using pure copper and ten percent tin bronze in moulds with varying
proportions of sand and clay. The cooling rate of each casting will be measured and samples from the casting
will be subjected to metallographic analysis using optical microscopy. We will show what effect different
compositions of sand moulds has on the cooling rate and microstructure of copper and tin bronzes. The results
of the metallographic analysis might point towards a reason for change to other moulding material in the later
Early Bronze Age.

A hitherto unknown group of medieval lead glass vessels (some 70% PbO, only traces of Na and K) from North
West Europe was established by screening methods; its connection to a unique contemporary recipe of
Heraclius (De coloribus et artibus Romanorum III, 8) was reported in Heidelberg 1990. Later analyses by
Wedepohl et al. confirmed these results. Now, to clarify the nature of the colours in these objects (bright yellow
and emerald green transparent, red opaque) and further details of the recipe, experimental melts of the original
glass composition were performed. The intensive yellow is mainly due to iron, not lead oxide.
Variable amounts ("...put as much as you think proper...") of brass fillings were described in the recipe "if you
wish to make it appear green". In Wedepohl's analyses the copper content varies and is indeed correlated with
the alloying metals of medieval brass (Zn, Sn). Test melts showed that introduced as elements, not oxides, they
can indeed influence the redox situation and the emerald green hue of the glass depending on the experimental
parameters. The recipe recommends generally: "Keep stirring it". Further scientific details of Heraclius' unusual
precise recipe are discussed. The close relationship to a group of medieval lead glass vessels justifies to name
them "la Heraclius".
82. Ceramics from Tell Brak, Syria: Observations of Technological Change

Different materials and methods of manufacture of a long sequence of ceramics (c. 4th - 2nd millennium) from
Tell Brak are considered using traditional typology, surface features, petrography, and replication (forming and
firing). Chemical analysis (ICP) is used to supplement other information to determine which wares were
imported. Of particular interest are changes in the ceramic paste that occur over time in vessels of a similar
shape, and presumably similar function. In many cases changes appear to be governed not by technological
considerations, but by tradition. The trend is particularly well illustrated by shell tempered and heavy basalt
tempered wares that have a limited distribution. The use of both tempers may be associated with a change in
dietary habits and food preparation respectively. The use of local materials and techniques as revealed by
limited ethnographic study was also valuable in considering ancient sources for fuel, clay, and temper. For the
non-cohesive local clays, hair and heavy organic inclusions were used to improve workability and reduce
cracking and distortion during drying. Unlike other areas that offer a relatively wide range of materials for fuel,
this region's most abundant - and easily available - fuel is dung, which from micromorphological evidence of
other sites has a long history of use in the region. Test-firings in the field indicate that many of the vessels
recovered from Tell Brak from all periods can be easily reproduced using local materials in kilns fuelled by
dung.

The last comprehensive summary on the study of Carpathian obsidians has been published recently by
Williams-Thorpe (1995), indicating that all open questions in this field have been answered. However, it seems
that there are still problems to be solved. Even in the above mentioned review article the current lack of routine
application of the provenancing methods was mentioned and the need for further non-destructive methods of
analysis and characterization was emphasised.
Hypothetical sources in south-west Ukraine still remained unexplored and claims for Romanian sources not
adequately tested. Provenance of some artefacts found in Eastern Hungarian museums is still unknown and
could not be matched with known Hungarian and Slovakian sources. The characterization of further sources and
artefacts by sensitive analytical methods could reveal further existing connections. The comparative raw
material collection of the Hungarian National Museum (LITHOTHECA) contains a good collection of samples
which we intend to complete with new samples and analyses.
59
Archaeometry '98, Budapest
Surveying the applied routine techniques it was found that very sensitive and promising techniques like LAICP-MS (laser ablation - inductively coupled plasma - mass spectrometry technique) or non-destructive PIXE
(particle-induced X-ray emission) method are not well represented or have not been used at all for the
characterization of European obsidians. A complementary method, PIGE (proton-induced gamma-ray emission)
method was used only for the characterization of some Near - Eastern sources.
The LA-ICP-MS is a multielemental, cheap, fast, precise and nearly non-destructive analytical method. (It
means, that small ablation crater pits of less than 0.08 mm are made, which are invisible to the eyes.) As it
produces crater of about 200 mm in depth it gives information well below the surface nevertheless "punctual".
The PIXE-PIGE method is less sensitive, but non-destructive, and in the case of "micro beam" mode it is
capable to analyse surfaces as small as about 1 mm2, moreover, it produces maps showing the elemental
concentration distribution laterally.
In this work, a comparison of these two methods, LA-ICP-MS and PIXE-PIGE, will be presented, analysing
mainly Hungarian source materials and artefacts. For comparison, results on samples from Armenia, Iceland,
Mexico, Slovakia and Turkey will be included as well. Interpretation of the results has been carried out through
cluster analysis on elemental concentration data.

84. Casting Moulds from the Upper Dnieper Region (10th-11th centuries
AD)
Natalja Eniosova
Archaeological Department, Moscow State University,119899 Moscow, Russia
Stone and clay casting moulds were found wherever the traces of jewellery production have been identified.
The Viking Age settlement at Gnezdovo lies on the arterial river road of the Russian state in the 9th-11th
centuries has yielded a large collection of fragmentary crucibles, metal ingots and more or less finished
products. It gives the direct evidence of the jewellery manufacture at this site. Casting moulds are the most
important objects that will give us a lot of information about casting process, working methods, technical
standards and professional skill of Gnezdovo craftsmen. The objects discussed in the present paper fall into two
groups. The first group is of stone moulds which were used for the casting of: 1) lunula-shaped temple rings
with imitation of granulation work; 2) round pendants with central boss and geometrical ornament; 3) nails
with embossed heads; 4) buttons and weights. The moulds were made of soft fine-grained sedimentary rocks
well fitted for carving. They are identified as siliceous rock of biogenic origin(opal), greenish-grey sandstone
and limestone. Besides Gnezdovo the most fitted artefacts come from the West-Slavs (Moravian) and Balkan
regions, Scandinavia and the Old Russian towns (Staraja Ladoga, Novgorod, Kiev). The absence of any traces
of using and experimental tests have clearly shown that stone moulds could have been intended presumably for
casting of metal with low melting temperature. The second group is of clay casting moulds used for the casting
of tortoise brooches and possibly for trefoil and round ones. Chemical and microscopical analysis shows that
moulds were made of fine clay tempered with sand, chamott and organic materials. Some fragments contain
more the 50% of additions. Tempered fabric for moulds brought many advantages: it could withstand higher
temperatures and became more porous, also the shrinking effect was diminished. Clay moulds from Gnezdovo
show three types of fabric: clay without additions, clay with sand and chamott, clay with chamott, clay with
sand, chamott and organic materials. All clay fragments from Gnezdovo belong to the piece-moulds made of
two fitting pieces. The back portions of mould are always plain. The front portions have a gently rounded
exterior. Some moulds have two layers of different fabrics: the inner one containing additions and lute of fine
clay without any additions. Clay piece-moulds permitted a high degree of mass production because one original
pattern could be used to make many moulds. A large variety of ornaments and an absence of experimental
objects testify the piece-mould casting technique had been brought to Gnezdovo by Scandinavian artisans. They
continued to follow the Nordic manufacturing tradition and produced the same kinds of the ornaments.

Aksaray, Nevesehir and Nigde provinces in Central Anatolia were searched with remote sensing techniques.
The central Anatolia is rich in prehistoric mounds, tumuli, flat settlement and ancient road remains.
The geographical co-ordinates of the archaeological sites such as mounds, tumuli, flat settlements,...etc. were
measured by GPS (Global Positioning System) during site surveys to locate them on the satellite images in an
accurate way. Archaeological features were investigated on Landsat TM and SPOT Panchromatic images by
Principal Components Analysis (PCA) and edge enhancement techniques. PCA was applied to all the seven
bands of the Landsat TM satellite image. Prewitt compass gradient mask operators were applied in the northwest, north-east and south-east directions.
The visual interpretation of PCA showed that second and fourth components have more archaeological
information than the other components. The edge enhancement techniques were especially useful in observing
ancient routes. This study is still continuing with new techniques and new satellite images of higher resolution,
such as Indian IRS 1C.
86. Non-destructive analysis of copper alloy artefacts from Pagan Norse
Graves of Scotland
Dr Katherine Eremin
National Museums of Scotland
Work is currently being undertaken on the production of a corpus of the Pagan Norse Graves of Scotland. As
part of this project, many of the copper alloy artefacts from the graves have been subjected to scientific
analysis. Most have previously been described as bronze without analysis. Similarly, other studies refer to most
Norse copper alloys as bronze but few published analyses are available. The aim of this study was to
determine the composition of the artefacts and the decorative methods employed, assess their variation, and
relate the results to artefact type, source and period. The grave assemblages are diverse, with material
attributed to Scandinavia, the Irish Sea area and continental North West Europe. The artefacts analysed include
oval and penannular brooches, ringed pins, harness and strap fittings, and buckles. Non-destructive analysis
was undertaken using X-ray fluorescence and scanning electron microscopy. The analyses indicated a range in
compositions. All oval brooches, attributed exclusively to Scandinavia, were brass. Most Insular artefacts were
bronze, although some artefacts with Scandinavian influence but of probable Insular manufacture were brass.
The ringed pins, of Insular origin, formed a diverse alloy assemblage, including bronze, brass and gunmetal.
Some artefacts reflecting Irish influence were bronze or gunmetal with appreciable levels of silver. The main
decorative features were mercury gilding and tin plating, with silver wires on some oval brooches. Brass is
relatively rare in Britain from the late Roman to early Medieval period. Its use in areas of Norse settlement
may suggest introduction from the Continent and Scandinavia.
87. An Ethnoarchaeological Comparison: The Kerkenes Archaeological
Survey and the Legends of Kerkenes City and the Keykavus Castle

When the ethnographic and ethnohistoric data collected from the Sahmuratli village is compared with Kerkenes
Archaeological survey nearby some parallels are seen. Sahmuratli village in Yozgat Turkey is situated at a place
which gives access to centrally placed resources such as pasture, agricultural land, water, flora and fauna,
mines, seasonal labour and public services. According to the oral history that exists among the villagers about
Mount Kerkenes and the Keykavus Castle on it, their origins seem to be embedded in the events that have taken
place on and around the ancient city through out history.

Anthropogenic soils have been identified at a number of localities in the Orkney Islands, Scotland. These soils
have been dated by radiocarbon analysis and stratigraphic relationship with settlement sites dating from the
medieval period to the late Neolithic/Bronze age period (c. 3500 - 2000 years BP). Thus, they provide an
outstanding opportunity to reconstruct early land management activity. An approach is being employed which
involves the combined use of multi-molecular biomarker information derived from the solvent extractable and
insoluble organic matter fractions of soils, stable carbon isotope analysis (δ13C and δ15N) of both individual
compounds and bulk organic matter, total phosphates and thin section micromorphology. Synthesis of the
analytical data and archaeological information has allowed identification of a range of organic materials
contributing to the formation of these anthropogenic soils. The results suggest a range of different grass turf
sources together with ash and the application of faecal material derived from a number of sources including
human, pig and cow. Specific biomarker structures and distributions have allowed very clear definition of the
manure inputs to the soils. Such observations suggest an intensive form of manuring practice enabling
sustained arable production in a marginal landscape highly susceptible to soil erosion.
89. Long-term dietary change in the Southern Channel Islands, California:
The evidence from San Nicolas Island
Joseph A. Ezzo
840 N. Alverno, USA
The entire burial collection from San Nicolas Island, California, numbering nearly 300 individuals from more
than 20 archaeological sites and numerous isolated finds, was analyzed for morphological traits and
paleopathology. Trace element analysis was undertaken on a subset of 74 individuals from 13 sites and two
isolated contexts, and stable isotope analysis was performed on a subset of 42 individuals from this group. The
bone chemistry study focused on five sites of known age: SNI-40 (4000 B.P.), SNI-16 (3300 B.P.), SNI-56
(1400 B.P.), and SNI-18 (300 B.P.). The results indicated that dietary change through time was evident,
although it did not follow a linear trend. Early on in the occupation of San Nicolas Island interactions with the
mainland coast of southern California appear to be quite significant, influencing the composition of island diets,
and this trend recurs very late in the archaeological record. In the intervening period, there appears to be
relatively little interaction with the mainland coast. A second focus of inquiry involved the identification of
auditory exostosis in individuals, and its relationship to subsistence practices. Auditory exostosis results from
regular exposure to cold water, in prehistoric Channel Islands populations, it occurs almost exclusively in males
and has been interpreted as resulting from diving for shellfish in the tidal pools. Auditory exostosis occurs in all
periods of occupation of San Nicolas Island, and the bone chemistry data suggest that shellfish was an important
component of the diets throughout the period analyzed.
90. The importance of firing atmosphere in the production of coarse
ceramics with calcite and chamotte inclusions

Coarse ceramics constitute about 70% of the ceramic findings in the archaeological excavations of Roman age
in Northern Italy. It deals with uncoated ceramics whose body contains significant amounts of inert inclusions.
They were used to realise both cooking pots, vessels for liquids and storage jars. The firing of coarse ceramics
seems to have been mainly realised in pit- or pile-kilns.
62
Archaeometry '98, Budapest
In the ambit of the present research some experiments have been carried out by firing a series of specimens in
pit-kiln. The specimens were realised with suitable shape and dimensions by using a body without inclusions or
with inclusions of ground calcite or chamotte. The aim was to verify the behaviour of the materials during
firing, as well as the microstructural and mechanical characteristics of the different mixtures. In particular, the
shrinkage during drying and firing, the phase composition, the porosimetric distribution, the mechanical and
thermal shock resistance were determined. To evaluate the role of the firing atmosphere, the same bodies were
fired also in an electric laboratory kiln, with oxidising atmosphere.
The results point out that the firing atmosphere does not influence the characteristics of bodies containing
inclusions of chamotte, while different results are obtained with calcite inclusions. In particular, pit-firing
allows temperatures as high as 800°C are reached without to promote the calcite decomposition and subsequent
decohesion of the artefacts as it occurs in oxidant environment. This situation determines an increase of
mechanical resistance of the materials without to compromise their integrity and functionality.

***Department of Classics, The University of Manitoba, Winnipeg, MB R3T 2M8, Canada.
The present study aims to shed some light on the complex picture of Aegean Bronze Age pottery systems, by
investigating the ceramic assemblage, predominantly Middle Helladic, from the site of Eleusis. An integrated
application of instrumental neutron activation analysis (INAA), thin-section petrography and scanning electron
microscopy (SEM), it aims to identify different ceramic traditions, to distinguish between local and imported
pottery and to verify sources of imports throughout the period.
The detailed archaeological study established eleven pottery groups, on the basis of fabric, form and surface
treatment. A total of 180 samples were selected to represent these features. The results of INAA and thinsection petrography coincide to show a series of distinctive compositional groups. One of them contains mainly
Middle Helladic Matt-painted pottery and is characterised by the presence of volcanic inclusions, with the most
likely source being Aegina. Another contains Middle Helladic Grey Minoan pottery and comprises fine grained
fabrics with inclusions not indicative of origin. Local ceramic production seems to have been limited, as the
majority of the painted pottery and some coarse wares appear to have been imported, while no distinctively
local fabrics were identified. The technological SEM study shows a large degree of internal homogeneity within
each group, suggestive of different traditions related to different production centres.
In general, it becomes obvious that, at least during the Middle Helladic period, Eleusis was the recipient of
imports coming from larger centers of production.

Since the North American peoples had not emerged beyond the primary stages of Copper Age technology prior
to European contact, early archaeological studies typically assumed their tool traditions to be a more recent and
thus less significant phenomenon as compared with their Old World counterparts. Recent work, however, has
shown that the North American copper working traditions can be extended back to the Archaic period (circa
7000 B.P.) demonstrating a variety of socketed and tanged projectile points, knives, harpoons and other items
which cannot be considered any less complex nor morphologically inferior to those found throughout the Old
63
Archaeometry '98, Budapest
World. In many cases, tool morphologies common to both sequences exist contemporaneously despite the
certainty of two completely separate developmental sequences.
This paper presents radiocarbon and metallographic evidence from which it becomes apparent that the Archaic
peoples from the Great Lakes region of North America employed a systematic process of cold-working and
annealing native coppers in order to skilfully fabricate a number of artefact types. We now know that these
people were turning out very complex, beautifully shaped tools and weapons as early as the seventh millennium
B.P. and possibly earlier. The quality and craftsmanship of these pieces suggests that their architects possessed a
good working knowledge of the mechanisms involved in annealing coppers as well as an understanding for its
effects in relation to the physical behaviour of the metal.
93. European connections - Implications of lead isotope ratios in early 17th
century trade kettles from Eastern Canada

Fragments of copper kettles are often found on early 17th century native sites in eastern Canada. These kettle
remnants provide us with samples of the copper being smelted and formed in European foundries during the
same period. Isotope ratios of the traces of lead in these copper artifacts contain information on the geological
sources of the copper ores being mined, and possibility the extent to which metal from various deposits was
being mixed in the production process.
Swedish copper from Precambrian sulphide deposits of the Bergslagen region can be clearly identified
isotopically. Historical records indicate that copper mining was taking place in this region at least as early as the
mid. 14th century. A second copper source, whose location has not been identified, has isotopic rations similar
to many Palaeozoic European sulphide deposits. For example the mines at Mansfeld, Germany, were known to
be producing large quantities of copper in the 16th and 17th centuries.
Some kettles have lead isotope ratios which lie between the values for the two above sources. Mixing of ores or
smelted copper may have been taking place, or other, as yet unidentified ore sources, may have been in use. A
series of copper samples believed to have been traded into Atlantic Canada by 16th century Basque merchants
have an unusually broad range of antimony contents as determined by INAA (80-3800 ppm). Isotopic analyses
of the lead in these samples is being undertaken to determine whether they were all produced from the same
copper ore.
94. Reconstruction of Paleodietary Behavior of Archaeofaunal Remains of
Garhwal Himalaya, India

Department of History and Archaeology, HNB Garhwal University, Srinagar -246 174 U.P. India
The present study is based on the trace element analysis of archaeofaunal remains excavated from different
archaeological sites, i.e. Thapli, a Painted Grey Ware site (first mill. B.C.), Ranihat, Mordhwaj, Banderkhet, the
early historical sites and Malari, a cave burial site (c. 1000 B.C.) of mid-Central Himalayan zone of India.
Based on the estimation of Carbon and Nitrogen isotope ratios, reconstruction of paleodiet in animal remains
has already been studied by various workers. However, it is also established that, besides study of isotope ratios
of Carbon and Nitrogen, the trace elements (Sr, Ba, Mg, Mn, Zn, Ca, etc.) are also helpful in reconstructing the
paleodiet of ancient animal population. Therefore, the aim of present study is to reconstruct the paleodietary
behaviour of different animal remains, like Cattle (B. indicus), Pig (S. scrofa cristatus) and Goat (C. jharal)
collected from different type of archaeological sites of Garhwal Himalaya.
The bone samples were analysed through Inductively Coupled Plasma Emission Spectrophotometry (ICP) in the
Laboratory for Archaeological Chemistry, Department of Anthropology, Wisconsin University, Madison, USA.

diet in their diet. However, the higher ratios of Sr/Ca, Ba/Ca and lower concentration of Zinc as compared to
reference, clearly suggesting that these animals, from various altitudes were particularly of herbivore group.
Therefore, it is concluded that trace elements, i.e. Sr, Ba, Mg, Zn and Ca can be used to assess the diet and
dietary behaviour of the ancient animal population.
95. Matters in Atomic Spectroscopy
Freirí Gándara, M.J. and Freiría Gándara, M.C
Faculty of Scicences University of Vigo, Vigo, Pontavedra, Spain.
Atomic absorption spectroscopy provides a sensitive means of determining several elements. The method is
well suited for routine measurements by relatively unskilled operators. Quantitative atomic absorption methods
are usually based on calibration curves, which, in principle, are linear.
When a beam of polychromatic ultraviolet or visible radiation passes through a medium containing gaseous
atoms, only a few frequencies are attenuated by absorption, and the spectrum is made up of a number of very
narrow (about 0.005 nm) absorption lines.
Emission and absorption spectra for both atoms and elementary ions are obtained from flames. Atomic emission
spectra are produced when an atom or ion excited by the absorption of energy from a hot source relaxes to its
ground state by giving off a photon of radiation. In contrast, atomic absorption takes place when a gaseous atom
or ion absorbs a photon radiation from an external source. It is important to appreciate that, when the same
electronic transition is involved, the energy of an emitted photon is identical to that of an absorbed photon.
Thus, the wavelength of the emitted radiation is the same as the wavelength of the absorbed radiation.
In atomic absorption spectroscopy, the radiation from a special type of external source is passed through the
inner cone of the flame, through a moderadiation detector. In contrast to molecular absorption methods, atomic
absorption methods do not employ a continuous source of radiation but instead use sources that emit lines of
radiation that have the same wavelength as that of an absorption peak of the analysed.
Flame atomic absorption spectroscopy spectroscopy is currently the most widely used of all the atomic methods
because of its simplicity, effectiveness, and relatively low cost.
96. Analytical techniques used in art and archaeology
Freiria Gandara, M.J. and Freiria Gandara, M.C.
Faculty of Sciences, University of Vigo. Vigo, Pontevedra, Spain.
Analytical techniques useful for the examination of archaeological finds and works of art are discussed
extensively in the scientific literature. They include molecular spectroscopies, atomic spectroscopies, x-ray
tecniques, electron spectroscopies, and nuclear techniques.
IR spectra have been mostly used for identifying and investigating organic compounds, and applications have
covered amber provenance, studies on pigments, varnishes, paintings, identification of dyes, etc. Ultraviolet and
visible spectroscpy finds a major application in the study of fluorescent radiations emitted by pigments, oilis
and varnishes. Raman spectroscopy has been used, for example, for identifying inorganic pigments.
Atomic absorption and emission have been fairly used in pottery studies. Atomic spectroscopies are also
suitable for the analysis of glass and metal objects.
The most striking results have been obtained with the use of x-ray radiography for the non-destructive
examination of paintings. X-ray diffraction can be used successfully for identifying inorganic pigments in
paintings, and it can also be used for identification of inorganic phases and inclusions in ceramic bodies. X-ray
emission is a favourite techniques for mutielemental analyses of valuable objects, even though sensitivity is
lather low with respect to other techniques. X-ray fluorescence is one of the most universal techniques for
achaeometric analyses and has been used in the study of a great variety of archaeological materials, from pottery
to glass and vitreous materials, pigments, and metals. Electron probe microanalysis has been used in the study
of pottery, glass and vitreous materials, pigments and metals.
65
Archaeometry '98, Budapest
X-ray photoelectron spectroscopy (XPS) has been used to study pottery sherds, glass, and bronzes. Major ose of
Auger electron spectroscopy (AES) has been in obtaining concentration maps and profiles by non-destructive
beam scanning on sample surfaces and cross sections.
Neutron activation analysis (NAA) is a most favourite technique for the analysis of works of art and
archaeological items. It has been used in the analysis of stone, pottery, natural and artificial glass, pigments, and
metals. PGAA or PGNAA (Prompt -ray (neutron) activatoin analysis) applications have covered elemental
analysis of metal objects, and detection of moisture and voids in masonry structures. Nuclear techniques useful
in the examination of works of art include also -radiography and autoradiography. Higher penetration of -rays in
comparison with x-rays makes -radiography suitable for the investigation of statues, plasters and masonry.
Autoradiography is particulary suitable for the non-destructive examination of paintings, where decay sequence
of elements containing in pigments begins with aluminium and follows with manganese, copper, arsenic,
antimony, chromium, iron, mercury, and cobalt. Lead containing pigments, however, which form the basis of xray examination of paintings, cannot be revealed by autoradiographies. Mössbauer effect spectroscopy (MES) is
a nuclear resonance spectroscopy and has been particularly used for studying iron containing materials.
Mössbauer spectroscopy can be used for obtaining informatio on firing conditions in ancient pottery
production, and in the study of iron containing pigments and obsidian.
97. New developments in the analysis of archaeological ceramics by total
reflection X-ray fluorescence (TXRF)

Spain
TXRF combines and optimizes the advantages of more standardized and well-known techniques such as ICPMS or EDXRF. On the one hand, it can be a suitable technique for analysing multi-elemental solid phase
samples without any chemical manipulation. On the other hand, it can be a powerful tool in the analysis of
multi-elemental liquid phase samples obtained by acid digestion as well. Due to its geometrical characteristics
(where the angle of incidence of the primary X-ray beam is about 4 min of arc) the detection limits of TXRF are
103 times higher than EDXRF and similar to those obtained by ICP-MS. It prevents the advantage of
minimizing matrix effects because of a substantial improvement in the peak-background ratio in comparison
with traditional XRF. Nevertheless, its extensive application to the analysis of archaeological ceramics has not
been started yet.
A previous work carried out by ourselves showed that TXRF provided precise semi-quantitative results (at least
for 15 chemical elements) with a simple sample preparation process. In that work, pottery samples were
analyzed in suspension and without any chemical manipulation. The results were also compared with a clay
reference material analyzed by NAA. These experimental procedures were used to characterize the first century
BC Numantian pottery production from the Spanish Central Meseta. Traditionally, whenever such pottery was
found outside this region, conventional approach thought that this was the outcome on an incipient trade.
This work presents the new developments carried out by TXRF in the analysis of archaeological ceramics. At
the current stage of research TXRF can provide highly precise quantitative results (at least for 22 chemical
elements) by means of a microwave acid digestion preparation process of the sample. In this study, such
preparation process and the comparison of the results with the clay reference material analyzed by NAA are
illustrated.

This synthetic protocol has been developed and successfully utilized in the American South over the past five
years. It has been applied to both prehistoric and historic archaeological sites at working depths of 2 meters or
more. The GPR systems used are standard models familiar to many workers while the cryoprobe is a variant of
the types developed in Germany and Switzerland in the early 1990s. The single greatest difference between the
U.S. and European versions is a complete reliance on nitrogen as the coolant in the American South due to the
elevated ambient air and soil temperatures. Rapid recovery of intact, relatively uncompressed, sediment
columns have been obtained for in-field comparison to GPR data of adjacent archaeological deposits. This
protocol has increased confidence in the interpretation of the radar data enhancing its role in the overall
characterization of the archaeological site as a whole.

Pottery of the late 6th and 5th century from the archaeological site of Velia has been studied. Investigations
were performed on both fine ceramics (black glazed ware, Ionian cups) and coarse pottery (common ware,
amphorae and bricks).
The pottery was analysed by a combination of thin-section and heavy mineral analysis and only to a small
extent by chemical analyses (RFA). Additionally samples of ceramic raw materials available at the region of
Velia have been studied and compared with the pottery products.
For most of the common ware (decorated and non-decorated), local production can be assumed. Some fabrics
however, show large similarities with raw materials and pottery products from the neighbouring town of
Poseidonia (Paestum) and were probably produced there. Only very few samples of special classes of common
wares like some mortaria could be clearly identified as import products (Corinth, Calabria). It can also be shown
that at Velia several local clay sources and clay mixtures were used simultaneously.
The analyses of the so-called Ionio-Massaliote amphorae gave a similar result. A large part is likely of local
origin. Some seem to be imported from nearby Paestum. Subordinate products originating from Calabria,
Greece etc. could be also identified but only very few examples of the typical fabric of Massalia (Marseille)
could be found.
Also of interest at Velia are the numerous roof tiles from the late archaic mudbrick-houses. About fifty percent
of these bricks were produced at Velia using local raw materials. The source for most of the remaining roof tiles
seems most likely from a production site at Ischia. A small percentage of the roof tiles may have originated
probably from Calabria.
The analyses of the so called fine wares have yet to be fully completed. The small sample size, partly very fine
grained fabric and vitrification due to higher burning temperatures etc. make the analyses more difficult.
Furthermore the interpretation of chemical analyses is also limited at the moment due to the lack of reference
analyses (RFA) available from known production sites. Initial results point to several sources outside of Velia.
Only for a minor part of the studied samples can local production be assumed. The possibility that a part of the
production was located at nearby Poseidonia cannot be excluded.

Two well preserved kilns for pottery making were excavated in Osterhofen-Schmiedorf and Künzing in Lower
Bavaria during the fall of 1995. Both structures date to the Celtic time on account of pottery finds from the kiln
site. The kiln from Osterhofen-Schmiedorf will be discussed in detail here. It has two firing chambers of about
67
Archaeometry '98, Budapest
0.5 m in depth which are separated by a solid wall. The firing chambers are covered by a circular flue plate of
about 1.6 m in diameter with ventholes of 10 cm diameter. Nothing was found of the dome which presumably
had covered the kiln, while ceramics and charcoal were recovered from a hollow working area in front of the
firing chambers. No misfired sherds were found.
Neutron activation analysis shows that the material from the kiln site forms a unique group when compared with
other reference groups of Celtic ceramics. The kiln was systematically sampled and Mössbauer spectra were
measured of several profiles taken from the walls and the bottom of the firing chamber into the surrounding
loess. The samples within each profile were separated according to the colour of the material. In addition, firing
experiments were performed in the laboratory using a sample of loess from the kiln site. A comparison of the
Mössbauer spectra of samples from the kiln site with those from controlled firings shows that the clay in the
kiln was not exposed to high temperatures for any periods of time.

Experiments

Sardis was the capital of the Lydian kingdom ending with the reign of King Croesus who ruled from 562 to 547
BC. His legendary wealth was from the gold found in the placer deposits of the alluvial from the Pactolus
stream that flows through Sardis from mount Tmolus. The first gold and electrum coinage is attributed to the
Lydians.
The excavations began at Sardis in 1958 and continue under the Harvard-Cornell expedition, but the first
archaeological evidence for the purification of gold was discovered in 1968 in the area designated as Pactolus
North. The excavators found and recorded the parting furnace and cupellation hollows associated with gold
refining and silver recovery. The furnace bricks are found to be impregnated with considerable amounts of
silver absorbed from the purification process. In addition to various refractory remains gold foil fragments,
globules, cut lump, square sided tuyers and litharge cakes which physically fit cupellation hollows ware also
found in this area.
In this work the scientific examination of the 36 tiny selected samples by the excavators were received from the
Manisa Archaeological Museum and were studied by means of SEM and energy dispersive X-ray microanalysis
(EDX). Of those 26 were in the form of foil fragments, 3 were lump pieces, 5 were in the form of minute globes
and 2 were gold dust. The gold remains studied came from the 1968 excavation season and with the exception
of the gold dust. The samples of gold dust were panned from the bed of the Pactolus stream by mineralogist
during the survey and are kept at the Manisa Archaeological Museum.
The microanalysis results indicated that the silver content of the samples were between 0-35%. Copper content
of the samples are about the same and not exceeding 2%. According to the results, half of the gold foils are pure
and the others are having silver composition in the range of 1.1 to 22.8%. The surface as well as the bulk of the
gold foils show either extensive or fine porosity presumably as a result of parting process. The amount of
porosity seems to be related to silver content of the sample. In all the samples neither surface enrichment nor
platinum group elements were detected.
The preliminary results of the examination of gold treated in a series of refining replication experiments were
also discussed. The results of this work have an important bearing on the interpretation of the structure observed
in the Sardis gold samples.
102. Achievements in spectroscopic investigation of archaeological objects
in Hungary

Archaeometry '98, Budapest
Archaeological objects are often valuable or very precious materials, thus their destruction for a conventional
chemical analysis cannot be permitted. However, the knowledge of their composition is an important factor to
establish the origin of the finding, to clear the relationship of connected parts and pieces, to detect fakes etc.
Archaeometry serves for informing archaeologists on the appropriate task: archaeometry uses mainly
spectroscopic methods requiring only a limited sample quantity, or working as a non-destructive technique.
The beginning of application of emission spectral analysis methods for archaeological investigation of
prehistoric bronze findings was cited in the early literature. In Hungary, emission spectrographic techniques
were similarly used to analyze metal findings in arc discharge. Also the micro-spark technique was effectively
adopted, e.g. to identify the origin of various parts of a procession crucifix. K. Zimmer continuously furnished
information and evaluated the spectro-chemical methods, published in the literature, and applicable for the
various tasks of archaeometry.
Micro-spectral-analysis method for small sample quantities in solution, as well as the arc discharge technique,
helped to clarify the very delicate composition of various parts of the Roman Aquincum organ. The laser-microspectral analysis was used as a quasi-non-destructive emission spectrographic technique for the investigation of
a wide range of archaeological findings, first of all of metal objects. Results were suitable to compare and
identify prehistoric findings, as well as to detect inhomogenities characteristic of the ancient technologies.
Principally non-destructive analysis methods are the X-ray emission and fluorescence techniques. Very
effective serial comparison studies were performed and cited in the literature for the identification of e.g. silver
coins, or non-metallic materials, ceramics, glasses. However, there is a hard problem: the penetrating depths of
X-rays in various elements are different, therefore the composition of surface layers cannot be distinguished
from the base material. As a very effective ultra-micro analysis method can be counted for the future the totalreflection X-ray fluorescence (TXRF) method.
An extraordinary important handbook: Archaeometrical Research in Hungary has been collected by the
Archaeometry Working Group of the Hung. Acad. Sci. and published in 1988, in which 33 original publications
and 111 summaries of selected bibliography in geographical prospecting, dating, analysis of pottery, glass,
obsidian, metals, metallography, numismatics, painting materials, textiles, dyes, biological materials and
spectrochemical of findings are contained. A second volume of this handbook will be presented now.

The site of Asine in the Greek Argolid was populated more or less continuously from the Early Bronze Age (the
middle of the 3rd mill.) to its destruction in the end of the 8th c. B.C. The site shows evidence of several
thriving settlements , e.g. the end of the Late Bronze Age (the Mycenaean period), and during the Iron Age
down to its destruction at around 720 B.C. The site consists of several excavated areas: the acropolis, the
undertown, several burial areas and another settlement area some 100 meters from the acropolis. Typical for the
Bronze Age, there is no evidence of metal working per se but rich finds of metal objects - copper, lead, bronze,
gold, silver, and tin (as foil covering for pottery in LBA chamber tombs). For the Iron Age, there is evidence of
iron-working and possibly even smelting, but nothing specifically for bronze working, although many finds of
bronze objects.
The aim of the project is twofold: 1) to analyze all extant metal (copper, lead, bronze and possibly silver) finds
covering the 1500+ years of continuous inhabitation, to see which metal sources were in use at what period, and
what social/traditional and economic significance this has for the site and the region; 2) to look at various areas
of the site at specific time periods when the finds cover the widest range of contexts to see if there are
metallurgic differences in coeval metal sources - for the LBA, for example, finds from rich chamber tombs,
simple burials, the acropolis, simple houses and larger houses and for the Early Iron Age, houses vs. burials will
be compared.
The analysis method employed is lead isotope and chemical analyses and principal component statistical
analysis.
The significance of the results both archaeometrically and archaeologically will be discussed.

104. Experiments on Ancient Patination Processes of Black Bronzes

*Pariciusstr. 13, Regensburg
**Akademie der Bildende Künste, Nürnberg.
The results of recent analyses (Giumlia-Mair 1996; 1997) of ancient black-patinated objects, from Egypt and
Palestine, dated to the 19th c. B.C., as well as Japanese experiments (Uno 1929), suggested that the colour of
the patina - artificially created by a surface treatment on an alloy containing 1-2% of gold and silver, similar to
the Japanese alloy shakudo - could be deliberately changed by adding small quantities of other elements to the
copper-gold-silver-alloy.
Ancient texts also seem to suggest that in the ancient World and in later times in the East, different alloys,
treatments and patination processes were used to produce black bronzes, inlaid with precious metals.
The authors produced different shakudo-type alloys, containing small amounts of elements such as iron, tin,
arsenic, lead etc., similar to the alloys previously identified by analysing ancient objects, and carried out
patination experiments, employing various processes described in several texts of different provenance.
Metallographic studies revealed notable differences in the characteristics of the various samples. The structure
of the differently produced patinas and the inclusions were examined and analysed by scanning electron
microscopy in the Institute of Materials Science and Applied Chemistry, University of Trieste (Italy).
The understanding of the ancient texts on this fascinating material, has been greatly improved by the
experiments on the laboratory specimen. Earlier interpretations based on misunderstood statements have been
corrected.

105. The process of Neolithization of SE-Europe according to C14-dates
Roland Gläser
Forschungsstelle für Archäometrie der Heidelberger Akademie der Wissenschaften, Max-Planck-Institut für Kernphysik,
Heidelberg, Germany
The process of neolithization of Europe is for a long period under debate. After the model of a „aceramic or
preceramic Neolithic", similar to the cultural development in the Near East and first claimed by V. Milojcic,
some other theories had arisen. A widely accepted model is the „waves of advance", proposed by Ammerman
and Cavalli-Sforza at the beginning of the 70s. This model was based on uncalibrated 14C-dates, which gave the
impression of subsequent waves of Neolithic advance, driving the borderline between Neolithic and Mesolithic
cultures up to Northwest-Europe. This model was criticised by M. Zvelebil, who denied the existence of an
unflexible frontier between these two cultural stages. The 14C-dates from some sites in Greece (Argissa, Sesklo,
Franchthi, Knossos) suggested a transition to Neolithic during the 1st half of 7th millennium cal BC.
Before discussing these dates, one has to keep in mind, that the oldest dates for the Pottery Neolithic (PN) in the
Near East are at the beginning of the 7th millennium cal BC. This means that the transition from the PPN (=
Pre-Pottery Neolithic) B/C to PN A or from Mesolithic to Neolithic, respectively, has taken place at the same
time.
For the Aegean and SE-Europe, 14C-dates from following Early Neolithic sites are available: Hoca Cesme,
Yarimburgaz and Ilipinar X in Western Turkey, Argissa, Franchthi, Sesklo and Nea Nikomedeia in Greece,
Poljanica-Plateau in Bulgaria, Anzabegovo, Obre, Porodin in former Yugoslavia, Icoana in Roumania, Gyalarét
and Maroslele-Pana in Hungary. Dates from some of these sites place the Neolithic before 6000 cal BC.
During the 90s some contributors to this discussion made clear, that there is no evidence for the existence of an
„Aceramic Neolithic" in SE-Europe. That means, that all early dates for the Neolithic should be placed into the
70
Archaeometry '98, Budapest
Ceramic Neolithic of SE-Europe, i.e. Protosesklo in Greece, Monochrom Pottery in Bulgaria,
Starcevo/Körös/Cris in Central Balkans and the Carpathian basin.
The probability distribution of the Early Neolithic dates reaches its peak in the 2nd half of 7th millennium cal
BC. There is another small peak at ca. 7000 cal BC, caused by two dates from Argissa. These dates are deriving
from bone collagen coming from the former aceramic layer of Milojcic´s excavation. They suggest an early
phase of the neolithization process. Since the existence of this layer, formed only by several pits, can be denied,
they are clearly outside the range given by the other dates. The most probable explanation is a hard-water-effect
or other contamination of the bone collagen. If one excludes these two dates, the remaining dates give a
timespan for the neolithization between 6500 and 6300 cal BC, not only for Greece, but also for the central
Balkan, the eastern Carpathian basin and a region around the lower Danube. It is surprising, that there are no
dates before 6000 cal BC in southern and central Bulgaria and in western Turkey. The most convincing reason
could lie in geomorphological circumstances.
The probability distribution of the Early Neolithic dates indicates a step in the wave of advance of the PN,
beginning somewhere in the Near East at around 7000 cal BC, arriving in Europe at around 6500 cal BC and
surmounting the distance between Greece and the Great Hungarian Plain in 200 years. A similar observation
could be made for the neolithization progress of Middle Europe, i.e. the spreading of the Linear Pottery culture.
106. Alpha-recoil-track dating of biotites from Quaternary volcanics
K. Gögen, G. A. Wagner
Forschungsstelle für Archäometrie der Heidelberger Akademie der Wissenschaften
Max-Planck-Institut für Kernphysik, Heidelberg, Germany
Since its introduction by Huang and Walker in 1967, alpha-recoil track dating was sporadically applied to micas
from samples of archaeological interest. So far the validity and feasibility of this technique has not yet
sufficiently demonstrated.
The heavy recoil nuclei accompanying the a-decay leave short (10 - 20 nm) tracks in the crystal lattice. In
biotite this radiation damage can be made visible by etching and phase contrast microscopy. Such alpha-recoil
tracks are produced by 235U, 238U, 232Th and their a-active daughter nuclides (radioactive chain).
In order to study their potential for dating young tephra layers, biotite samples were collected from the Eifel
Quaternary volcanic area. For age calculation it is necessary to determine the track density and normalize it to
the uranium- and thorium contents, determined by fission-tracks induced by separate slow and fast neutron
irradiation. The latent alpha-recoil tracks are etched with 30% HF for ca. 20 min., reaching sizes of up to 1 mm.
The primary advantage of the alpha-recoil track dating over the fission track method is a several thousand-fold
increase in sensitivity. The applicable range of dating is ca. 103 to 106 years, depending on the uranium,
thorium content (1 - 8 µg/g) and the limiting areal density of alpha-recoil tracks (104 tracks/mm2).
Our investigations support this idea. The alpha-recoil track density grows linear with the known age of the
samples. This relationship allows the calibration of the alpha-recoil track clock. Biotites even from distant
tephra in the size range of 0.02 mm2 seem to datable. In terms of archaeochronometry this may be important to
date sections where archaeological layers are intercalated with tephra beds.

In 1996-97 the present authors examined the specific traits of the dyeing technology of Coptic polychrome
fabrics, including the famous Chale de Sabine, on the basis of 54 samples of threads from the Louvre collection.
The study was aimed at:
a/ reconstructing the technology used for dyeing fibres of different colours and various tints of a particular
colour
b/ estimating the possibilities of the applied research method for the dating and attribution of the relevant fabrics
71
Archaeometry '98, Budapest
c/ estimating the impact of water cleaning on the red dyestuff, i.e., madder.
With the aid of specially elaborated experimental methods both qualitative and quantitative analysis of dyes
have been carried out. We have succeeded in reconstructing the mechanism of the attachment of dyes to wool
fibres, in tracing the spatial distribution of dyes both on the surface and within the filaments and in estimating
the technological quality of dyeing.
We have reconstructed the means of obtaining a given colour and making it pure - more vivid for red, yellow,
green, blue, brown, black and white fibres from 14 textile samples. It appears that the applied method can be
effectively used for solving historical and culturological problems. We have also established that even soft
water cleaning may affect colour characteristics of the fibres dyed with madder.

Several theories on the date of arrival of the gold of Sudan to the North of Africa were developed based on the
Middle Ages literary sources.
Using 12 MeV proton activation analysis (PAA) and LA-ICP-MS we were able to show that the first gold
struck in Ifriqyia under the Ummayyads had the same characteristics as Byzantine gold. Under the Aghlabids
there was a change of the gold supply (characterised by high Ga and very low platinum group elements (PGE)
contents).
Under the Fatimids another gold supply seems to appear in the Ifriqyia and in the Maghrib mints (lower Ga and
higher PGE concentrations). This dynasty conquered the North of Africa in the 9th and 10th century and the
Egypt and the Syria in the 10th century. Also in the 10th century they shared with the Spanish dynasties the
Eastern and Western gold routes of Africa. We showed that after this separation the same gold (which is
different from all the others) was struck in Al-Andalous and in Sidjilmasa.
Does the Aghlabid gold come from Sudan or from other African sources ? Where does the Fatimid gold comes
from ? Are we able to distinguish the Sudanese gold from the gold of Nubia, Red Sea, ... ? Are we able to
approach the Muslim gold provenance problem in the Orient ?
In order to understand the routes of gold, mainly under the Fatimids, coins struck during the 9th and 10th
century in Misr and in Syria were analysed by PAA and LA-ICP-MS to follow, among others, the PGE and the
Ga concentrations. Nuggets and samples from African excavations have also been considered when possible.

It is under Darius I (522-486 BC) that the several Near East reigns of the Achaemenidae kings were organised
and enlarged, forming an Empire from the Indus to the Aegean Sea and from Syr-Daria to the Persian Gulf and
the first Nile cataract. In 334-330 BC all this Persian Empire was conquered by Alexander king of Macedonia.
In this Empire all the commercial transactions were made using gold and silver. It is so under Darius I that we
assisted to the creation of the first silver (sicle) and gold (darique) coins struck in the Persian Empire. However,
after its conquest by Alexandre the Great and even after his death (332 BC) staters of Alexander and (his father)
Philip type (struck all over the Greek World) are also struck in the Persian mints (like, for example, in
Babylon). In fact the stater was used all over the Mediteranean basin; we must notice that the first Gallish coin
was a reproduction of the Philip stater.
Coins have always been struck in known mints (particular mint marks) during certain periods. The
determination of their composition indicates the changes on gold and silver sources in time. Using 12 MeV
proton activation analysis (PAA) and ICP-MS associated with laser ablation (LA) we determined the major,
minor and trace elements of coins struck in the mints of Persia, Greece, Egypt, ... in order to follow the
manufacture technologies and characterise the gold and silver minerals of these empires.
We present here the first results on the origin of several European, Near East and African precious metals used
from the 5th to the 3rd century BC.

The study of colouring agents in glass finds from the glass workshop of Diósjenő, castles of Visegrád and Buda
is the starting point of a co-operation project on glass analysis between the Centre Ernest Babelon in Orleans
(France) and the Department of Electrostatic Accelerators of the Institute of Nuclear Research (ATOMKI) of
the Hungarian Academy of Sciences in Debrecen (Hungary). Glass samples spread in date between the 14th and
the 17th centuries from these archaeological sites were studied by the Centre Ernest Babelon using LA-ICP-MS
and by the ATOMKI using (micro)-PIXE-PIGE methods. These preliminary results allowed to discriminate
between the soda-lime glasses (importation from Venice) and the potash-lime glasses (made locally). The sodalime glasses are dated from the 14th to the 16th century and in this group we find some bottles, cups and
bracelets from the Palace, Buda Castle and Lower Castle. In the potash-lime group we find mainly 15th and
16th century glasses which are often heavily corroded due to their potassic composition. In this group we find
mainly glass windows from the Palace and Buda Castle and one cup from the Lower Castle.
During the first part of the project we have mainly focused on the cobalt blue glasses. Our aim was to extend
to Central Europe the systematic study of the Orleans group on the origin of cobalt blue pigments in French
glass from the 13th to the 18th centuries. This study will allow the characterisation of the provenance of cobalt
blue pigments used by glass craftsmen in Hungary in this period. Their former study — based on French
objects found in medieval glass workshops, cathedrals and excavations — has shown for the first time that at
least four different types of cobalt ores have been used during this period. For three of them the provenance are
the mining districts of Freiberg and Schneeberg in Germany as it was shown on the base of geochemical
evidence as well as studies of ancient texts. In the last group we find all the cobalt blue glasses made by the use
of ancient Roman tessare. Different chemical association characterise these ores. For the German ores we can
cite the Co-Zn-Pb-In association, the Co-Ni-Mo association and the Co-As-Ni-Bi-Mo-W-U one.
The period of use of these ores is also well established and ore determination can be used, in some cases, as a
dating method. For example, one of the studied glasses, a glass window from Buda Castle dated from the 16th
century is certainly older than supposed and the analytical results allow us to date this glass from the 14th-15th
centuries. A systematic study of the trace elements, inclusions and local heterogeneity in other type of colouring
agents like copper, and also in colourless glasses would lead us to the better understanding of used medieval
glass manufacturing technology.

The aim of the project is, for the first time, to identify first generation migrants amongst archaeological
populations of the Pacific. In order to decide whether any human individual was a migrant to a particular island
and the direction of any migration, archaeologists have previously relied on a combination of stylistic and
linguistic patterns together with oral tradition. This project pioneers the use of Thermal Ionisation Mass
Spectrometry (TIMS) in the study of the movement of human populations across the Pacific, focusing on the
problems associated with so-called Polynesian Outlier populations. Measurements have been made on the
radiogenic isotopes of strontium and lead within the enamel layers of archaeologically-derived human dental
remains. By comparison between these measurements and the database of geological measurements made on
Polynesian Islands, it is possible to comment directly on the mobility of prehistoric island populations.
Of the three geo-cultural groups defined by Domeny de Rienzi, (Dumont-D'Urville 1832), the most cohesive
and perhaps the most appropriate grouping, is that of the ‘distinct race’ of Polynesia (Thomas 1989). These
peoples inhabit the islands of the Pacific within the near-triangle formed by Hawaii, Rapanui (Easter Island) and
Aotearoa (NewZealand). The similarity of physical appearance and social customs across the region allow for
the unambiguous identification of these people to geographic location. It is generally accepted that Polynesians
settled their islands and started to become a distinct group after 3200 BP on the islands of Fiji, Tonga and
Samoa. Their ancestors had travelled from Island Southeast Asia or Melanesia in the West (Smith 1995).
The Polynesian Outliers fall outside of the triangle formed by the Polynesian islands, but these island societies,
eighteen in all, speak Polynesian languages. They have been variously considered as either relic populations left
behind after their colonising friends and relatives moved east, or as representing a return west after most of the
eastern Pacific islands had been settled. Recent studies suggest rather more complex histories, including cultural
replacement, and highlight the need to consider each island individually rather than as a group (Bayard 1976,
Kirch 1984, Davidson 1992). No matter what the case is for individual `Outliers', evidence is emerging from the
middle of the second millennium AD for a major rise in Polynesian influence west of the `triangle' (Spriggs
1993). Some of the strongest evidence for this comes from the islands of Vanuatu, where burials (e.g. Granger
1982) and social systems (Spriggs 1986) are recognised as having Polynesian traits.
For archaeologists the frustration has been in the inability to identify whether this influence was due to actual
migration of Polynesian communities into the islands, or through cultural transmission requiring contact rather
than relocation of people. A third, but less likely possibility is independent development of traits similar to
Polynesian due to a shared ancestry (Spriggs 1993). Archaeologists have recovered a number of human burials
75

in Vanuatu and the Solomons that have been said to represent the original Polynesian migrants to these islands.
Result will be presented that provide a rigorous test for these claims.

Instrumental Neutron Activation Analysis and Eastern Terra Sigillata-II Pottery Revisited
113. Instrumental Neutron Activation Analysis and Eastern Terra Sigillata
- II. Pottery Revisited
Jan Gunneweg*, Márta Balla**
*Institute of Archaeology, Hebrew University, Jerusalem 91905, Israel
**Institute of Nuclear Techniques, Technical University of Budapest, H-1521 Budapest, Hungary
At the Mediterranean harbor town of Caesarea Maritima in Israel built by King Herod, hundreds of remains of
Terra Sigillata-II vessels and pottery fragments of the Early Roman period (1st c. BC-AD 2nd c.) have come to
light in recent excavations. This pottery is well stratified and can be well dated. Stylistic similar ware belonging
to a much later period, Byzantine, was found in another area at Caesarea.
Roman Terra Sigillata wares may be considered as one of the more important indicators of trade items because
they are easily distinguishable and readily available. It was, therefore thought useful to trace them to the
manufacture site(s) in order to establish trade routes and/or inter-regional relations between Caesarea and
remote lands.
Samples of 12 different types of this ware (Hayes' Sigillata B/1-2 ware) were submitted to Instrumental Neutron
Activation Analysis at the Nuclear Reactor situated in the Institute of Nuclear Nuclear Techniques at University
of Budapest in a collaboration program with the Hebrew University of Jerusalem in order to learn the
provenience of the Sigillata wares.
Uni- as well as multivariate statistical analysis programs were employed to find the most likely chemical match
for the Sigillatas and purported centers of pottery production in the Eastern Mediterranean.
This study showed that ETS-II is a conglomerate of various forms which has a unique chemical composition
and which the archaeologist can easily distinguish by eye from other Sigillatas on the basis of its physical
properties.
The much later Byzantine version of this ware, similar in "look" is of some importance because it was shown
that the same pottery manufacture center continued to produce its output over a much longer period of time than
was previously thought.
114. Instrumental Neutron Activation Analysis Used to Search Whether
Late Bronze Cyprus was able to Imitate Greek Mainland Mycenaean IIIa-b
Wares

Mycenaean IIIA-B pottery has been manufactured in the mainland of Greece during the Late Bronze Period. It
was exported to various regions in the Mediterranean basin. Among these regions is the island of Cyprus. It has
76
Archaeometry '98, Budapest
been suggested that Cyprus made its local imitation of Mycenaean pottery, stylistically indistinguishable from
the Greek imported specimens.
Our objective was to see whether Mycenaean pottery found in Cyprus originated in Greece, or that Cyprus had
been able to manufacture its own. For that purpose, samples of Mycenaean pottery found at Cyprus were
subjected to Instrumental Neutron Activation Analysis at the Lawrence Berkeley National Laboratory and in the
Hebrew University of Jerusalem to obtain a chemical composition of the wares, in order to show convincingly
whether Cyprus had been able to reproduce this style of pottery.
INAA has satisfactorily proved to distinguish chemical compositions on the basis of 5 major and 25 trace
elements, constituting the "chemical fingerprint" of a ceramic which is assumed to be characteristic for each
source on earth from which clay was taken.
Uni- as well as multivariate statistical analyses were employed to separate and group the INAA data and to
find a chemical match with purported pottery manufacturing centers.
The different chemical compositions at several regions in Cyprus, among which specifically Eastern Cyprus,
suggest that there was an import of Mycenaean pottery from the main Argolid manufacture centers, whereas
later, the local Cypriote Mycenaean pottery production superseded the imported version.
The importance of this study shows that the Cypriote clays gave the local potters the possibility to imitate
Mycenaean IIIA-B wares since certain clays in Cyprus are of a highly similar "look" when fired into a ceramic.
Furthermore, there was a search for a better chronology to be obtained from other Cypriote local wares in
whose context the Mycenaean imitations had been found.
115. Chemical and Nutritional Analysis of Ancient Food Remains from
Hungary/Central Europe
Ferenc Gyulai
Archaeological Institute of the Hungarian Academy of Sciences Budapest
The analysis of food remains poses a great challenge. This work requires simultaneous familiarity with botany
and chemistry. In the analysis of food remains, additional opportunities are offered by chemical analyses.
Results of such investigations shed light on the kind of food recovered, its ingredients and additives, nutritional
value as well as the mode of preparation.
Modern analytical chemistry has made the analysis of the main components and trace elements in food remains
possible.
Due to the previously mentioned moderate carbonization caused by charring, only a limited group of
compounds may be expected to survive.
Nevertheless, results have contributed significant information on food consumption and subsistence culture of
prehistoric people. Food remains are rarely encountered during the excavation of sites even cemeteries and
settlements where food is clearly a major cultural component. The identification of these finds contributes to
reconstruction of ancient ways of life and gastronomic history.
Under the climatic conditions prevalent in the Carpathian Basin, food remains, when found, are usually
preserved in a carbonized form, probably as a result of exposure to relatively mild heat in an anaerobic or at
least oxygen poor environment.
An increasing number of archaeological excavations have been accompanied by scientific analyses during the
past few decades. As a result, prehistoric food remains have also been recovered. Remains of carbonized bread
were found following the water-sieving of samples gathered on the floor level of burnt Ottomány (Middle
Bronze Age) culture houses at the tell settlement of Túrkeve-Terehalom.
During study of the inside of another sherd from the Copper Age site of Zalaszentbalázs - Szőlőhegyi mező a
small brownish-blackish spot of typical burnt food remains was discovered. The shape, color and thickness of
this spot, on the other hand, is very similar to analogous remains found at lake dwellings in Switzerland and
Southern Germany and to what was identified as simple flour soup.
77
Archaeometry '98, Budapest
Carbonized food remains recovered from a Tumulus (Late Bronze Age) culture refuse pit at the site of
Balatonmagyaród-Hídvégpuszta. Macroscopical and microscopocal analysis, in addition to the instrumental
analyses all indicated that remains of Bronze Age strawberry shortcake were here found.
During the course of excavations at Keszthely - Fenékpuszta in 1980 a 60 cm thick, ashy layer was found when
a pit dated to the Celtic Period was excavated. The using methods all lead to the conclusion that the grayishblack ashy layer, rich in fish bones, were the remains of a fish soup.
116. The Analysis of Brass Samples from the Ball and Warminster sites in
southern Ontario, Canada

The Ball (circa. 1616 - circa. 1635 A.D.) and Warminster (circa. 1625 - circa. 1649 A.D.) sites are located 0.5
km apart in southern Ontario. The chemistries of 214 brass samples from the Ball site split into three major
groupings: low tin (>0.1%); medium tin (0.7-2.3%); high tin (2.7-6.3%). Each of these groupings are subdividable into tighter chemical sub-groups, based on their trace elemental contents, forming more than a dozen
sub-groups. As expected from the proximity of the two sites, most of the chemistries of the 100 brass samples
from Warminster match the Ball sub-groups, confirming that there was major interaction between the peoples at
each village. Both sites contain both red and yellow brasses. There is little evidence that specific brass
chemistry sub-groupings appear at only one site lending credence to the assumption that the brass distributions
represent the slow overlapping transition in occupation from Ball to Warminster.

Excavation and survey during the 1996 and 1997 field seasons has shown that there at least two components
widely separated in time at the Birimi site in the Northern Region of Ghana. The Kintampo component dates to
between 3000 and 4000 B.P. and the Middle Stone Age (MSA) component is estimated to date to 30 to 40,000
B.P.
During both the Kintampo and MSA occupations siliceous mudstone was used as a lithic raw material. Artifacts
from the two occupations can be distinguished on the basis of lithic production technology as well as degree of
patination. A possible raw material location has been located about 25 km from the site. INAA is used to
examine the similarity between the artifacts and the siliceous mudstone from the raw material location. It is also
used to examine the chemistry of the artifacts from the two components and to address the question of whether
the same raw material resource was being used during different occupations of the site.
118. Deformation of burnt structures and archaeomagnetic error

A surprising feature of compilations of archaeomagnetic results is the dispersion in the data points. Apart from
the uncertainty in the age, given by the archaeologist and accepted as such, the reliability of the magnetic
measurements must also be questioned. This is despite laboratory tests designed to eliminate poor quality
magnetic data.
78
Archaeometry '98, Budapest
Various sources of error have been investigated over the years, including magnetic refraction, "kiln-wall fallout" and magnetic anisotropy. Little attention has been given to possible movement due to subsidence or
pressure from overburden. The deformation of a hearth or oven is difficult to assess as these structures could
have been deformed by high temperatures whilst functioning in antiquity.
The recent discovery in the Rhone valley of a series of flat hearths dating from the late Bronze age (11th
century B.C.) has enabled this to be tested. The site of Laprade, between Orange and Montélimar, was one of
many recent rescue excavations carried out by AFAN along the future Valence to Marseille TGV line.
The habitat yielded three hearths, one of which was markedly dome-shaped, and these were the subject of an
archaeomagnetic study. The latter hearth gives a poorer archaeomagnetic result than the others, but this is
dramatically improved if the individual samples are "bedding corrected" into a horizontal position. Clearly the
deformation occurred after the hearth was abandoned probably by subsidence of the poorly fired edges.
This result shows that archaeomagnetic analysis of apparently deformed structures should include a
consideration of a tectonic correction.

Outside

We know the explosion into the work place of available and relatively inexpensive "high tech" science in
Archaeology over the past decade is transforming how we analyze and view the past. It is also transforming
how we do business. An increasingly larger segment of archaeometric and geoarcheology training and
application, for example, is aimed at an interested leisure public anxious to learn and do technological
applications in unravelling history and to pay for this opportunity. This paper will focus on the role and value of
archeometry in the growing market place of citizen participation in historic and ecological conservation and
eco-tourism.

Strabo tells in his "Geography" that the two harbours in antique Alexandria were separated by an "embankment
called the Heptastadium. The embankment forms a bridge extending from the mainland to the western portion
of the island (of Pharos) and leaves open only two passages ... which are bridged over". Alluvium deposits, on
which lies a large part of the city of Alexandria, have completely masked the traces of this embankment and its
position in the large existing isthmus was, till now, entirely conjectural.
New studies have been undertaken since 1995 in order to establish a valid position of this significant feature of
the antique city. This was done in co-operation between our team (Département de Géophysique Appliquée,
Université de Paris 6 and C.N.R.S., Garchy), the Centre de Recherches Alexandrines (I.F.A.O., Cairo) and a
colleague from the Helwan Observatory.
Several investigations were conducted in different ways: ancient documents and maps, old streets network,
levelling survey, local information, metrology and various geophysical methods which could be worked out in
the unfavourable (damp and salted ground) of the city, i.e. radar, electro-magnetic conductivity, electrostatic
resistivity and seismics.
79
Archaeometry '98, Budapest
Despite the fact that the Heptastadium definitely does not appear as a geophysical marker, several original data
concerning the structure of the isthmus could be gathered (existence of a resistant nucleus with sharp edges,
contribution of a primitive islet to sedimentation, probable position of a passage, ...). Finally a new strong
hypothesis for the position of the Heptastadium, consistent with the well-known street network of Alexandria,
can now be ascertained.
121. Amphora sherds dating from the Middle to Late Roman Empire
Darren J. Hillegonds, M. E. Lipschutz
Purdue University, Department of Chemistry
We have begun a study of amphora sherds dating from the middle to late Roman Empire. The samples are from
the Roman port town of Leptiminus, near modern Lamta, in the Sahel region of central Tunisia. They are
primarily derived from surface survey, and represent a cross-section of the common rim types extant at the site.
Approximately 50 samples have been analyzed via INAA, with the resulting data used as selection criteria for
carbon isotope analysis, utilizing accelerator-based radiocarbon and stable isotope mass spectrometry.
Great quantities of Tunisian amphorae have been found all over the western empire, providing a tremendous
opportunity to explore trade in the ancient world. Central Tunisian amphorae have been extensively studied
topologically, but until the present study there has been no direct dating evidence for any of the middle or late
Roman amphora forms at Leptiminus. We intend to combine INAA data with carbon isotope analysis in order
to see how groupings assigned via trace elemental composition vary in time and carbon isotopic characteristics.
Preliminary results show agreement between presumed and measured manufacture dates. The stable isotope
analysis shows a 10 per mille range in δ13C values, which indicates that while the carbon extracted from the
sample is contemporary to manufacture, it was derived from various sources. Groupings assigned on the basis
of trace elemental concentrations are reflected in the radiocarbon data, while the stable isotope data shows no
correlation with assigned elemental groupings.
122. Late Neolithic Ceramic Exchange Networks: New evidence from
Northern Greece

House, West Street, Sheffield S1 4ET, UK.
The organisation of ceramic production and the extent to which households, and even communities, competed
in the exchange of ceramics is of prime importance in investigating the development of society and economy in
the Neolithic. Analytical studies which illuminate the technology of production and especially the provenance
of early pottery groups, enable us to trace the distribution of different components of the ceramics assemblage,
both within settlements and over long distances.
This paper summarises the results of a three year study of the 'Dimini' phase ceramics (early fifth millennium
BC) from the large settlement at Makrygialos, in Northern Greece. A programme of petrographic analysis was
conducted on 300 samples chosen from this extensive site. 150 samples of typologically similar vessels were
also analysed from neighbouring sites in Central Macedonia, as well as Dimini in Thessaly.
The analytical programme has characterised the technology of different ware groups found within this
chronological phase, enhancing our understanding of both utilitarian and high quality ceramics. Distinctive
petrographic fabrics demonstrate extensive exchange of fine ware bowls and other non-utilitarian ceramics
some of which appear to have been produced in the Plain of Thessaly, a distance of c.125 km. Such an
extensive movement of different classes of pottery over long distances at this early time demonstrates an
unexpected complexity in ceramic economy, previously only thought to pertain to comparatively rare materials
such as obsidian. Ceramic analysis is therefore shown to be integral to a new understanding of economy and
social stratification in the Late Neolithic.

Anthropological and botanical evidence presently available suggest that the Tyrolean Iceman („Ötzi“) has had
its origin in the Vinschgau valley in South Tyrol. In a attempt to test this hypothesis we analysed the trace
element and isotopic composition of skull bone fragments from pre-industrial North and South Tyrol together
with two bone fragments from the Iceman. The Tyrolean bone material from 83 individuals from 19 different
villages located on 5 different geological backgrounds was taken from the „Tappeiner collection“ at the
National History Museum Vienna. Originally the skulls were collected from ossuaries in Tyrol at the end of the
last century. We sampled soil, water and stream-sediment in order to trace the geochemical fingerprint
(„isotopic and trace-elemental“) obtained by the bones from local nutrition during the years before death or by
possible contamination during burial.
The area encompassing North and South Tyrol has large geochemical compositional contrasts between
Limestone’s, both in the North and South, and the Central Gneiss zone in the middle. The skulls coming either
from limestone (87Sr/86Sr = 0.709 + 0.001) or gneiss areas show large Sr-isotopic differences of 87Sr/86Sr =
0.709 + 0.001 and 87Sr/86Sr = 0.712-0.732 (range), respectively. The bone fragments from the Iceman have a
87
Sr/86Sr = 0.7182 ± 0.0005 which is clearly within the values of the gneiss area. The gneiss area however
encompasses both the Vinschgau, south, and the Oetztal, north of the last resting place of the Iceman. There are
systematic differences in the trace element composition (e.g. Li, Mg, Sr, Mo, As, Ga, Cu, Ag, and Pb) of the
skulls between these two valleys. In our presentation we will present statistical analysis of ratios of these traceelements which allow us to determine the most likely region of origin for the Iceman on the basis of his bone
(geo)chemistry.

You might be interested in the symbol of Archaeometry '98 Symposium and how it relates to the subject.
The conference symbol is a copper age depot find from Szeged-Szillér, containing a heavily used prehistoric
artisan's kit: a hammer-adze, different chisels and awl. This attractive kit was published by Ferencz Pulszky,
former director of the Hungarian National Museum, distinguished archaeologist and politician of the last
century. Pulszky published the basic monograph on Hungarian Copper Age - which is one of the rare instances
when tools made of native copper are of real importance. This period of historical significance was established
on the basis of the chemical analysis of the metals, also quoted in the same monograph by the author. The
Szeged-Szillér depot finds therefore is symbolising several aspects of our conference - archaeology, analyses,
technology and an appreciation of the past.
The find assemblage featured in several archaeometrical analyses in the past. Also, it is included in on-going
comprehensive studies on early copper industry. Our studies are focused on this tool kit specially, from the
respect of composition, provenance and technology.

We should present our complex (petrological and archaeological) researches on the stone-materials of
Százhalombatta. In the fortification Ildikó Poroszlai have been excavated for 1989 to 1993. She opened three
sections, and she found the bequest of the Bronze Age People (Nagyrév culture from Szigetszentmiklós phase
to Vatya culture to the Koszider period): houses, streets etc.
Among the available finds of the Bronze Age tell-settlements studied, high amount of rubbed or chipped flint
implements, millstones, weights, moulds, stone axes, hooks and other microliths and stone implements used for
manufacturing and building work have been turned up. In the archaeological part we made statistical,
typological and microwear investigations.
In the part of petrological the stone findings about 435 samples were studied by the unconventional techniques
of geological, geochemical material tests.
Among the millstones, besides the Carbonitic granites, varieties of Miocene andesite from the Visegrád
mountains were identified, as well as sandstones and fine grained conglomerate have also been found.
The most characteristic materials of stone axes were the above mentioned andesites, but serpentinitised
metadolerits (Picrite Formation at Budakeszi), as well as some siliceous shale and quartzite were also used.
The materials of chipped stones are mainly chert and hornstone, which can be found both in the Buda and
Gerecse mountains.
The results of analysis have proved, that the stone implements originated from the neighbouring district within a
distance 50 km from the Eastern part of Central Massive of Transdanubian region in Hungary.
The identification the places of origin has indicated that the most probable migration area of the manufacturers
was the Dunazug Mountain Range and its immediate vicinity.

During field surveys and studies performed during last decades, concentrated on several tens archaeological
sites spread over the whole state territory, several thousands of polished stony artefacts were collected. Among
three hundreds of artefacts studied by means of thin sections, except of widespread greenschists, amphibolites,
alkali basalts, andesites, blueschists, antigorite serpentinites and others, there were documented also peculiar
rock-types.
From the site Nitriansky Hrádok axe made from eclogite was described. As eclogites are not known from the
Western Carpathian territory, the provenience of this raw material type should be located to the Bohemian
Massif.
In the western part of the Slovak Republic on several sites spinel-hornblende-anthophyllite (nephritoide) schists
were studied by the use of electron microprobe in detail. The presence of green, Al-rich spinel, represents the
most interesting aspect of the provenience of this rock-type in central Europe. No such rocks are described yet.
Consultation with several colleagues from abroad prove this statement.
From the Sobotiste (near town Myjava - western Slovakia) axe made from jade (jadeite) was picked up in fields.
So its exact position is not known. Emerald-green rock is very fine-grained with granoblastic fabric. Studies in
detail are in progress.
Site Sarisské Micha’lany (eastern Slovakia) supplied several artefacts made from pelocarbonates (mixed rock
composed of clay minerals and carbonates). This raw material represents typical local rock-type of the
Paleogene strata in wider environment.

The site of Mendes, Egypt (Tel el-Rub'a) is located approximately 90 miles north of Cairo, in the Nile delta.
The site is characterized by the remains of several economic activities, including glass making, the production
of lime plaster, ceramic firing and metallurgical work. Waste material, in the form of slag, is produced in
addition to these finished products. A combination of Instrumental Neutron Activation Analysis (INAA), X-ray
Fluorescence (XRF) and thin section visual microscopy was used in order to identify the activity that produced
the slag at Kom el Adhem. The glass making activities which appear to date to a late occupation of the site
(Hellenistic-Roman), represented by the slag, comprise one element of the local economy. The analysis of slag,
in conjunction with other work, such as pottery analysis can help delineate the economic importance of Mendes;
i.e. better understand the economy of the site and its role as a harbour town.

As prosecution of a work focused on the microchemical study of iron smelting slags from an early Middle Ages
site found near Peveragno (Cuneo, Piemonte, north-western Italy), the characterisation of lead, iron and bronze
artefacts, such as weapons, home life objects etc. has been carried out. The archaeological excavation, started in
1993., evidenced the presence of an inhabited place located on a terraced area obtained with a noteworthy rock
levelling actions which caused the partial destruction of a village dating back to V-VI. century B.C. The more
recent human presence was attributed to a peopled settling dating back from III. to VI century A.C. From the
examination of the archaeological findings, there is no clear evidence of a metallurgical activity until V. century
AD. From this time to the VI. century AD at Peveragno intense metallurgical activities were carried out as
evidenced by the remains of furnaces with a noticeable amounts of slags and iron artefacts spread all over the
site.
Among the iron objects, one sample attracted the attention of the researchers for the presence of a surviving
copper plating on both the surfaces of an iron sheet. It is worth noting that even though the copper plating on
iron was undertaken from the earliest use of iron, continuing through Roman and medieval times, the copper
plated iron objects are quite rare and, to our best knowledge, the sample found at Peveragno is the first found in
Italy. The object under study is quite flat, irregular shaped with the following dimensions 10 by 5 cm and 1 mm
thick. The microchemical structure was studied by means of SEM + EDS and then, on the base of the
microanalytical results, several experiments are carrying out in order to ascertain the copper layer is
characterised by a thickness ranging from 100 to 200 micron, and it must be underlined that the copper is
continuos on one side of the iron artefacts with a complex microchemical structure quite similar to that observed
in the so called Ramo Secco bars and in the Aes Rude. Indeed, the presence of iron island dispersed in the
copper layer was evidenced as in these latter materials characterised by iron-rich alpha spheroids (20-40
micron.) where are dispersed very small copper particles. On the contrary, the opposite copper layer is highly
defective and is characterised by an entirely different microchemical structure with a very thin interdiffusion
layer between iron and copper with a scarce presence of the iron rich () phases. On the base on these results, it
can be ruled out a dipping technique and the first results of the copper plating experiments suggest a more
sophisticated plating technique.

130. Determination of the iron ore source exploited for early iron smelting
at Tell Afis (north-western Syria) through microchemical studies

At Tell Afis (north-western Syria), during a stratigraphically related archaeological excavation, a large group of
iron artefacts and iron smelting and smithing slags have been found. These materials are dating back from 1000
BC to 800 BC. The evidence for such an important technological breakthrough in this area, puts forward the
question about the iron ore provenance. In order to gain a further insight into the development of the early iron
metallurgy in this region and to locate the geographical sources of the iron ores exploited at that time, the iron
ore outcrops of the north-western Syria have been sampled (Kurd Dagh mountains, Syrian Kurdistan). It is
worth noting that historical sources indicate that this area classic Döliche "ubi ferrum nascitur", is supported to
be located there.
The iron ores found in the Kurd Dagh mountains, in particular at Kerry and Alamdar, have been found mainly
composed of hematite, whose content ranges from 37 to 73%, anatase with a small amount of arizonite and
rutile. These iron ores have been subjected to micro chemical characterizations and to smelting processes
carried out adopting experimental conditions similar, as soon as possible, to those used in an antique furnace.
The attention has been focused on the micro chemical aspects involved during the smelting process and on the
chemical composition of the slags that result from the process. The microchemical and microstructural studies
have been carried out by means of the combined use of X-ray photoelectron spectroscopy (SA-XPS), small area
X-ray induced Auger electron spectroscopy (SA-XAES), scanning electron microscopy (SEM) + energy
dispersive spectroscopy (EDS), X-ray diffraction (XRD) and differential thermal analysis (DTA) + thermal
gravimetry (TG). The micro chemical information have been compared with those obtained from the study of
the archaeological iron smelting slags and from the inclusions entrapped in the iron metallurgy products could
be proposed. Indeed, the presence of TiO2 -rich phases have been found in the archaeological materials as well
as in the iron ores and in the modern smelting slags.
131. Lead anchors and ingots from Is Piscinas (Montevecchio mine basin,
south-western Sardinia, Italy)
G.M. Ingo*, R. Falciani, G. Chiozzini, G. Bultrini, M. Gucciardi, T. Agus, R. Ruggeri
*Consiglio Nazionale delle Ricerche, Istituto di Chimica dei Materiali, CP 10, 00016 Monterotondo Stazione, Roma, Italy
During a series of surveys along the coast of the Montevecchio mine basin, several Phoenician, Punic and
Roman anchors from shipwrecks have been found at Is Piscinias. It is worth noting that some of these
unfortunate ships are characterised by the presence of charges of lead ingots and further, other lead ingots have
been found scattered along the coast. 12 Roman lead anchors of the 28 identified and some lead ingots have
been retrieved from the sea and their chemical composition and microchemical structure have been studied.
Some lead ingots are very similar in shape to the parallelepiped form found so frequently in the Mediterranean
basin. They have an upper dimension of 34 by 10 cm, a base of about 37 by 15 cm with a weight of about 35
kg. The inscription on these ingots is IMP CAES HADR AUG and therefore, they have been manufactured
during the time of the Emperor Hadrian (AD 117-138). Other lead ingots are characterised by a slightly
different form and very similar to the Roman late Republican ingots found also in Sardinia at Mal di Ventre
(first half of the 1st century BC). Other ingots have a very different form and unfortunately, nor marks and signs
have observed on them, neither other materials have been found, that allow to precisely date the shipwreck.
Only some of the smaller lead ingots and lead slabs are decorated with parallel notches, but these signs are not
able to indicate the date or the people that have manufactured them. Concerning the form of these latter lead
ingots, they are characterized by different shape, plano-convex and quite rectangular shaped slabs weighting 1
to 18 kg. The chemical composition of the lead ingots have shown that the tin content is ranging from 0.3 wt. %
to 0.85 wt. %, zinc from 0.02 to 0.81%, antimonium from 0.30 to 0.80 %, silver copper, manganese, iron and
bismuth are lower than 0.4 %. The microchemical structure of the lead ingots is characterized by the presence of
high copper tin particles whose diameter is ranging from 1 to 4 micron. In order to localise the metal ore
resources exploited for producing the lead ingots and anchors, lead isotope analysis has been carried out for
these metal artefacts to compare with data of lead ore deposits of the Mediterranean basin. With this aim in
mind, the most important lead deposits of Sardinia have been sampled and lead isotope ratios were determined.
85
Archaeometry '98, Budapest
From the comparison between the lead isotope ratios for the lead ores and the lead ingots and anchors it is
possible to identify two main metal sources, that are some Spain lead mines and the Montevecchio basin,
respectively. In particular, concerning this latter Sardinian lead ore source, the results show that is has been
exploited for producing the lead ingots manufactured during the time of the Emperor Hadrian.
132. Processing Fishes with Obsidian Tools: A Description of the
Experimental Microwear
Maria Rosa Iovino
Via F Mauceri 21, 96100 Siracusa, Sicily, Italy
The exploitation of fish, during Mesolithic and Neolithic period, also for a ever increasing nautical competence,
was very important for people but often, if we have fish remains in an archaeological context, it is difficult to
understand how people exploited this natural food resource. More even, in several sites near the sea fish bones
not always are found for different reasons: it could depends on behaviour or it could depends on pH soil nature.
Functional analysis can attempts to identify these lost data.
Few functional studies1 have addressed the nature of the microwear resulting from processing fish with
obsidian tools.
Making a reference to a well preserved Mesolithic-Neolithic fishing site (Uzzo's Cave, Trapani, Sicily;
Franchthi's Cave, Argolide, Greece) we have conducted experimental activities to scaling and butchering a lot
of different fishes (Thunnus, Epinephelus, Sparus aurata, Diplodus sargus, Dentex dentex, Mugil cephalus and
Scorpaena scrofa). This case study attempted to observe the differences in microwear formation depending from
the different kind of fish and from different quantity of fish worked. From this experimental work results that
on obsidian implements it will be possible to recognize, very well, butchering fish. Scaling fishes reserves more
problems, in fact not always this activity produces a well developed trace; but when it happens we could have a
good collection comparison to identify the kind and the quantity of fish processed.

Iron Age deposits in Serbia

Zavod za zastitu spomenika kulture, YU-34000 KRAGUJEVAC, Krag. oktobra 184
Results of quantitative and statistical analyses of 101 depots from Serbia from the period between Late Bronze
Age - Early Iron Age will be discussed . In these depots, 2965 metal objects were found. We divided them into
46 different sorts (weapons, tools, instruments, utensils, garment...). Quantitative analyse of objects give to us
some precise conclusion about the nature of depots, i.e. about cult or prophanic character. Among the 2965
objects, nearly 70% are bracelets, 50% celts (axes), 30 sickles, lances, needles, buttons... But, the other kind of
objects are present with less of 20%. The most numerous depots are those containing only one type of object
and among them most frequently depots with bracelets. It is also evident that depots are more numerous in the
period of Late Bronze Age / Hallstatt A1 and toward to the Hallstatt 2/Hallstatt C number is obviously less.
Judging by damage of some tools we can recognise a cult character of certain depots.

Chemical analyses of ancient glasses show compositional groupings based primarily upon the type of alkali
used in their manufacture. However, the final glass composition is dependent not only upon the nature of the
alkali and its constituent salts, but also its manipulation through mixing, purification and melting. Therefore an
analytical study of the nature of the raw materials used in glass manufacture, through to the production of
experimentally produced glasses, may indicate the factors behind the final compositions. These include how
composition is influenced by initial selection, by technological modification through ashing, solubility and
volatilisation, and by the choice of glass recipe. This paper summarises the first results of a project which
addresses the problems of working back from the chemical composition of Medieval glasses to the raw
materials. The work focuses on composition and subsequent behaviour of glass making, alkali raw materials
used in Medieval Northern Europe. To date, there are a number of significant results. The analyses of a number
of different organic alkalis has been undertaken by energy dispersive X-ray spectrometry, X-ray diffraction and
qualitative wet chemical techniques, to ascertain their constituent salts. These analyses have then been used to
predict the final glass composition and tested against glasses produced under controlled laboratory conditions to
a variety of different recipes. This project strengthens the scientific study of archaeological glasses and the use
of glass making raw materials, as chemical composition forms the very basis for our interpretation of glassmaking practices and their place in early societies.

The introduction of stable isotope analysis using carbon (13C/12C) and nitrogen (15N/14N) revolutionised
palaeodietary research in the 1970s. This technique has been used to analyse both the collagen and apatite
preserved in ancient skeletal remains and has been successful in assessing the consumption of protein vs.
carbohydrates, C3 vs. C4 terrestrial resources and marine vs. terrestrial resources of ancient populations. The
discovery that cholesterol is preserved in archaeological remains raised questions as to whether dietary
information could also be derived from its isotopic signature (Evershed et al., 1995). Cholesterol is a single
compound which can be unambiguously characterised, therefore ensuring its isotopic integrity. Preliminary
research has shown that the dietary signal derived from cholesterol is different from that derived from collagen
and apatite, and so its use in conjunction with these existing methods should give a fuller insight into palaeodiet.
Cholesterol can be separated, characterised and its δ13C value measured by using gas chromatography (GC), gas
chromatography-mass spectrometry (GC-MS) and isotope ratio monitoring-gas chromatography mass
spectrometry (irm-GCMS) (Stott and Evershed, 1996; Stott et al., 1997). Studies to date have demonstrated that
the δ13C value of cholesterol is almost homogenous within one skeletal type and highly consistent between
different skeletal members. It has also been used successfully to distinguish subtle dietary differences between
an English inland (Medieval, Abingdon Vineyard, Oxfordshire) and a coastal population (Saxon-Medieval,
Barton-on-Humber, N. Lincolnshire) (Stott et al., in prep.).
Current research in our laboratory is concentrating on determining the effects of differing nutritional inputs,
metabolism and turnover rate on the isotopic composition of bone cholesterol. Holtzmann albino rats were
raised on a variety of isotopically controlled diets consisting of differing combinations and proportions of C3, C4
and marine protein, and C3 and C4 energy components. Bulk δ13C values of the diet, bone collagen, apatite, hair
and flesh of these samples have already been measured in a previous study (Ambrose and Norr, 1993). The aim
of this work is to measure the δ13C content of the rats tissue cholesterol and individual fatty acids as a function
of each different diet with a view to determining how and which specific biochemical fraction (protein and/or
energy) present in their formulated diets most influences their lipid isotopic composition. Comparisons of the
cholesterol δ13C values obtained from studies of this type with those measured on cholesterol recovered from
ancient human bone should allow us to make more accurate interpretations as to the dietary preferences of past
populations.

The continually growing field of pottery provenance studies is beginning to present problems integrating
databases derived from different laboratories and different analytical techniques although some labs have
already taken the initiative to normalise their databases (Glasscock 1992). We are, therefore, pleased to
announce the development of a certified multielemental reference material specifically for use by laboratories
carrying out such compositional characterisation studies. Developed from an 80 kg sample of Late Iron Age
pottery from a site in the Free State Province, South Africa, this reference material will carry a certificate by the
South African Bureau of Standards guaranteeing that its preparation conformed to international standards.
Sample preparation (milling, blending and homogeneity checking) has been carried out by Mintek and is
currently being sent to a number of international laboratories for analysis. The results of these determinations
will be statistically integrated into certified values which can then be used with confidence for comparative
purposes.
It is recommended that all laboratories undertaking ceramic provenance analyses should regularly run
CERAMIC-1 as an aid for normalising data from different runs and between different laboratories. In addition,
a protocol should also be established between participating laboratories to govern usage and methods of
reporting data.

138. Tiffany or Loetz ? Identification of Art Nouveau Iridescent Glass
Artefacts

Art Nouveau iridescent glass has been highly estimated for its splendid, rainbow colour gleam. Iridescence
itself is an interference effect occurring, whenever a reflecting material is coated by a very thin layer with a
refractive index different from that of the bulk.
L.C. Tiffany was the first one to grant a patent for manufacturing glass with iridescent surfaces in 1881
followed by several centres in Europe, where the highest quality was achieved by J. Loetz Wwe. from
Klostermuehle in Bohemia. After the Loetz-Patent in 1898 an intensive production of iridescent glass artefacts
with exceptional quality started. Although influenced by objects of Tiffany Loetz artefacts were not the result of
an imitation but rather of a parallel development due to alternative technological approaches.
In a project of Austrian research institutions with the Museum of Applied Arts Vienna a "recognition"
procedure based on non-destructive analytical techniques supplemented with efficient experimental data
processing, which allows quick and reliable identification of Art Nouveau iridescent glass provenience, was
developed. More than 400 glass fragments and samples provided with the kind agreement of the Museum of
Applied Arts in Vienna, the New York Historical Society, the Passauer Glasmuseum in Germany as well as
private collectors have been analysed by FTIR (Fourier Transform Infrared Spectrometry) and XRF (X-ray
Fluorescence Analysis) in a non-destructive way. Small glass splinters taken from special fragments could also
be investigated by SEM/EDX (Scanning Electron Microscopy with Energy Dispersive X-ray Microanalysis)
after embedding in resin. Although this method is not entirely non-destructive its application enables a better
understanding of the chemical composition of the bulk glass and the iridescent layer.
The clusters obtained by the statistical evaluation of the FTIR spectra could be proved by XRF as well as by
SEM/EDX. In general, the chemical composition of the bulk glass used by Tiffany differs profoundly from
Loetz glass. Additionally, differences in the elements present in the iridescent surface layer could be detected
due to the different technologies used for the production of the iridescent glass artefacts by Tiffany and Loetz.

The site lies in the valley between the Sopron hillside and the Rust mountain chain, on a low plateau formed by
three rivers – the Zeisel-, the Ikva- and the Liget stream –, between 215-221 m above sea level. A surface of
20,000 square meters was excavated, which revealed a settlement with evidence of several phases of
development and a nearby cemetery (Jerem 1981). The settlement was in the path of the ancient European trade
route known as Amber Route. This excellent position explains why finds range in date from the Copper Age to
the late Middle Ages, and also why there are traces of various stylistic influences. The golden era of this
settlement can be dated from the sixth to the first century BC on the basis of items found in the cemetery, as is
confirmed by radiocarbon dating (Jerem 1984; Jerem et al. 1984-85).
Charcoal samples were collected from graves of Urnfield culture, end of Hallstatt and early La Tène period, in
addition to remains of bonfire, wooden grave-post or just remains of the nearby vegetation, and also from
structures of coeval settlements, as rafter, joist, remains of fire-places, furnaces, kilns, etc., in order to find

botanical evidence concerning the natural arboreal vegetation, the different uses of members of this vegetation
in architecture, in manufacturing, funerary practices and everyday life. Thus we can draw conclusions on the
effects of man on its natural environment and how this selection can influence the vegetation. We can also make
suggestions on the vegetational-climatological events. The applied methods in identification are stereo- and
compound- microscopical investigations with the use of different tree-anatomical atlases (Schweingruber 1978).
In some cases we have carried out derivatographic analyses so as to find out what the origins of the charcoal
can be, i. e. could it be from the nearby fire spot, or it is just a remain of a burnt or of a buried house, or just of
the buried vegetation. So we can understand more precisely the events that could have affected the culture, or
the life at the time. The basis of these suggestions is the separability of different charcoal types on the basis of
the temperature they burnt. Although, botanical investigations have been carried out at this site, but they gave
suggestions mainly on the cultivated vegetation (Badal et al. 1994; Rudner et al. 1997).
Results are unique in Hungary, as such a great area with the numerous material was not worked out for the
development, composition and uses of arboreal vegetation from the Iron Age. It is also unique for Central
Europe as well as for the previous and subsequent time periods.

State of research of the technologies of prehitoric cultures will be examined, beginning with Lepenski Vir and
Starcevo, till to La Téne period in the Central Balkans, with the special on the Danube region.
During last decades magy excavations of the important prehitoric sites in the South Pannonian plain
/Vojvodina/ have been carried out by different domestic and foreign institutions. The excevations were often of
a large size and long duration /Gomolava, Gradina Bosut, Zidovar, Rudna Glava, Vinca, Selevac, Divostin,
Blagotin/.
Published separately for every single site, the analytical results have never been observed in common. A variety
of analytical techniques were used, comprised all categories of relevant archaeological finds.
It would be useful to examine briefly present analytical results, with the intention to obtain first picture of the
interaction between Archaeometry and prehistoric archaeology of the area.

Quartz rich lithic materials were widely used in the manufacture of stone artifacts by the Palaeo-Indian cultures
in the Great Lakes region of North America. The Early Palaeo-Indians (ca. 12,000 - 10,000 YBP) used fine
grained chert, silicified quartz arenite, orthoquartzite and some quartzite, while the Late Palaeo-Indian Plano
culture (ca. 10,000 - 7,500 YBP) commonly used coarser grained materials, including quartzites, silicious
quartz arenites and sandstones from bedrock quarry sources. As many of these quartzites and sandstones are
visually similar, samples from several major quarry sources including the Lorrain, Bar River and Mesnard
Formations, and the Agibik and Hixton quartzite quarries, were examined using both destructive and nondestructive techniques. Multivariate analysis of chemical data from X-ray fluorescence (XRF), Instrumental
neutron activation analysis (INAA), and ICP-MS provides clear separation of several of these potential sources.
While these methods are useful in identifying source materials they may involve partial destruction of samples,
even in small quantities. The use of cathodoluminescence (CL) microscopy offer an additional non-destructive
method which has no lasting effect on the artifact sample. Samples from Hixton quartzite can be clearly
differentiated from older sandstones as the luminescence characteristics of the quartz grains, the early
chalcedonic rim cements, and the late pore fill chert each have distinct luminescence characteristics.
142. Colluvial sediments near archaeological sites as a key to the past
landscape evolution under human impact - a geoarchaeological case study
from the Kraichgau-Hills in Southern Germany

Kernphysik, Saupfercheckweg 1, D-69117 Heidelberg
In the loess covered Kraichgau-Hills in Southern Germany man has settled ever since Neolithic times. During
that time the landscape has undergone enormous changes documented in cut soil profiles in areas prone to
erosion and alluvial fillings in the depressions. Geoarchaeological studies in the vicinity of archaeological
excavation sites shall help to answer the question, whether these changes are mainly the result of human impact
or rather climatic variations. The colluvial and alluvial sediments represent an important archive for the
reconstruction of the past landscape evolution and the correlation of the remnants of archaeological settlements
with their time-equivalent sediments is of key importance. Therefore apart from archaeological and
palaeoecological investigations well resolved time records for these sediment types are necessary. Recently
achieved progress in the method of optically stimulated luminescence (OSL) makes it a powerful dating-tool to
close the chronometric gaps for sediment layers free of archaeological finds or organic material, even for
colluvial sediments with only short transportation distance. Infrared stimulated optically luminescence (IROSL) is considered the appropriate method to date the mainly fine grained loess derivates rich in feldspar.
The investigations are carried out in the study area of Bauerbach between an archaeological site with Neolithic
and iron age settlement remnants on a hill top and an archaeological site with remnants of Roman buildings in
the alluvial sediments of the river Kraichbach. Field studies reveal relief levelling with erosive lowering of
~1.5m on the hill top during the last 2.5 ka years and colluvial accumulation on the adjacent hill foot of ~5m
during a yet unknown time span.
First results of the geoarchaeological investigations and their possible implications for the human impact on the
past landscape evolution of the early settled Kraichgau-Hills will be presented at the meeting.
143. Determination of the Palaeolithic-Settlements’ position on the territory
of Serbia
Zvonimir Kaluderovic
Institut Archéologique, 11000. Beograd.
Palaeolithic period is the most unexplored prehistoric epoch in Serbia. Up to the eighties of this century, only
two Palaeolithic sites, discovered by chance and already partly destroyed, were systematically explored. During
the last decencies, thanks to the thematic field prospecting, more ten, mostly cave settlements were discovered.
Parallel to the field research, a model of the Palaeolithic settlement was founded on the territory of the great
ecological and geomorphologic diversity, in Serbia, i.e. the Central Balkan region.
91
Archaeometry '98, Budapest
Meanwhile, some regularities were noticed in this process, which could be valuable in discovering new sites,
reducing the chance factor. This model reconstructs the optimal conditions for setting an area or a site in
Palaeolithic period. Also, the elements of recent relief, pointing the Palaeolithic settlements were noticed. One
of the most important climatic elements, during the Ice age, influencing the choice of the settlement, was the
glacial and snow boundary at the definite height above sea level.
It is possible to determinate the optimal height above sea level of the Palaeolithic settlements by analysis of the
glacial traces in recent relief of Serbia. Distinguishing the definite height above sea level and comparing it to
other relief characteristics of Serbia, like existence of 1500 recorded caves and abrades, the way of discovering
new Palaeolithic sites was made considerably easier.

Following successful attempts to establish that the chemistries of turquoise blue and white glass trade beads
change over time, a preliminary study was begun to compare royal (cobalt) blue glass trade beads from early
17th century sites in southern Ontario with beads from a glass bead manufacturing house in Amsterdam. The
bulk chemistries of these beads mirror their fine state of preservation. They are mixed alkali (mainly soda) lime - silica beads with calcium contents usually above 4-5%. Their cobalt contents vary over a factor of six,
and some were opacified with up to 4% tin. The arsenic/cobalt atomic ratio of ÷2 fits with the possible source
of cobalt as a cobalt-arsenic ore (of common name smaltite) that was found in the Harz Mountains of Eastern
Germany, a source not too far from either Amsterdam or Venice, both known glass trade bead making centres
of the period.

Our knowledge on the conservation techniques used in the Old Kingdom of ancient Egypt is limited. In general
mummification is observed after simple drying of the body. To improve this process embalming was
increasingly performed from the Middle Kingdom onwards. The tomb of Idu II, the chairman of the pine wood
office (2150+/- 50 BC) was discovered in 1914 at Gizah and its content was brought to the Pelizaeus Museum
at Hildesheim. The mummy (Inv. No. 2639) essentially consisted of an unwrapped skeleton, the head was
bandaged. It was soaked immediately after recovery with paraffin.
Extracts of a clavicle fragment were subjected to GC- and GC/MS-analyses and revealed a wealth of wood tar
compounds including the antiseptic cedrol and gujacol. Acidified methanolic bone extracts yielded
dehydroabietic acid and its oxidized forms. Further support of the suggested conservation of the skeleton was
expected from sodium analyses. A 12-fold higher sodium content was seen by atomic emission spectrometry
compared to sodium analyses of bones from modern autopsies. The embalming proved to be beneficial for the
intactness of bone alkaline phosphatase. Clavicle fragments were employed to isolate the enzyme. During gel
chromatography the elution profile was essentially the same to that observed for the extraction of a modern
bone sample. The enzymic activity was allocated in either M (r) = 230+/- 30 kDa. The enzymic activity was
improved after affinity chromatography where the specific activity rose to 200 mU/mg, some 20% of the
activity obtained with a contemporary enzyme.
92
Archaeometry '98, Budapest
Proof of the unequivocal human origin of the ancient alkaline phosphatase was challenged in a specific ELISA
using a monoclonal antibody directed to the human bone enzyme. There was an immunoreactivity of 23%
93

compared to that of the enzyme obtained from modern autopsy. Furthermore, no microbial contamination of the
bones was detectable.

Carbonate microfacies analysis is a sensitive method in identifying the geological age and depositional
environment of sedimentary rocks (limestone, dolomite, chert, flint, etc.). The combined analysis of rock texture
and fossil content, associated with a detailed knowledge of regional geology, makes possible to assign
archaeological materials to precise locations, even to quarries.
The Palaeolithic tools of Bicske (Transdanubain Range, Hungary) were made of a fine-grained limestone,
deposited in a 10 million years old Middle Miocene (Sarmatian) reef. We found the origin in an abandoned
quarry at Páty, ca. 10 km away from the archaeological locality.
A Late Mediaeval statue found in the Buda Castle (Budapest, Hungary) is made of Late Tertiary limestone, rich
in fossils. By identifying the components and the depositional environment we suggest a relatively small area
within the Pannonian Basin as source of the stone.
Stone material both for tools and for statues have been carefully selected by their masters for resistance of wear
and weathering. If the rock contains fossils, the inexpensive method of microfacies analysis provides good
results in identifying the source of the material.
147. Finite Element Analysis for Failure Prediction of Archaeological
Pottery

Greece.
Prediction of function of archaeological pottery has been a long-standing subject of discussion, as it is affected
by many parameters, not always interpretable in a common sense. Mechanical behaviour is one of those
parameters which have attracted a lot of attention and therefore its accurate determination is essential.
In this paper we present a quantitative model that was developed, based on the Finite Element Analysis (FEA)
approach, for predicting the failure of vessels under almost any possible loading conditions, by taking into
account the shape. The vessel is divided into a large number of virtual elements, on which the strains, under any
type of loading, is calculated by the parametric solution of a large number of equations. The input needed for
the analysis are the Young’s modulus and the Poison’s ratio of the material as well as the geometric
characteristics of the vessel and the loading mode.
In order to evaluate the efficiency of the FEA approach, a series of ceramic pots were manufactured using a
calcareous clay and different sizes and volume fractions of non-plastic inclusions. TRS, toughness and Young’s
modulus of the ceramic material were determined using standard techniques. The maximum strain experienced
by the pots was then calculated by FEA, under different loading modes and loads. The actual pots were finally
subjected to mechanical loading, where the load at failure was found to be within 10-20% of the calculated
value. The results indicate, therefore, that the FEA method can be used to assess the failure behaviour of
94
Archaeometry '98, Budapest
ceramic vessels with sufficient accuracy. The model has also been applied to archaeological pottery with a view
towards predicting their mechanical behaviour.

A representative group of 500 selected brass and copper coins, all been found in the Tiber River, Rome, have
been chosen for analysis. For the first time, sampling of such a large amount of Roman coin, dating to the reigns
of the emperors Augustus to Claudius (27 BC to 54 AD), was possible ever. The concerning coins are filed and
stored at the Museo Nazionale Romano at Rome. Drilling into the coin's thin side yielded filings, which were
analyzed by electron microprobe (wavelength dispersive) for chemical composition. To the fore of our
investigation was to determine a presumable quantitative shift of trace elements in chronological order during
this time period. With the help of the analyses we strove for a better relative classification of some specific coin
types and the clarification of the relative sequence of the emissions. In our presentation we will report about the
first approach towards these goals of research. In the longer term of the project, we also wish to discuss the ratio
between products of the official mint at Rome to either those of a supposed auxiliary mint or uncontrolled
(illegal) imitations.

Instrumental Neutron Activation Analysis (INAA) was carried out on 52 samples recovered from the presumed
Pastoral Neolithic sites of Il Lokeridede and Jarigole which are located in the Sibiloi National Park on the
Koobi Fora Formation on the East shore of Lake Turkana near the Northern Kenyan borders with Ethiopia and
the Sudan. The elemental data obtained from the SLOWPOKE Reactor Facility [University of Toronto], can be
separated into two Groups (A & B). Group A samples represent both sites while group B samples come only
from Jarigole. Group A samples suggest that sherd material recovered from these two sites may have come from
a similar clay source. Since each of the sites contain samples of pottery ware that appear both physically and
chemically similar, site contemporaneity may be inferred. A radiocarbon date obtained on charcoal from the
IsoTrace Facility [University of Toronto] in connection with this project confirms the Pastoral Neolithic age
(2910 - 2575 BC) for the site of Il Lokeridede. This is the first AMS date obtained from samples from the
Koobi Fora Region. It is also the first date for any site in the Jarigole Mortuary Tradition.
150. The Invesitagion of Prehistoric Birch pitch Find by GC and GC/MS
Johann Koller, Ursula Baumer
Doerner-Institut, Barer Strasse 29, 80799, Munich, Germany
The tar obtained by smouldering birch bark represents the most important sealing and gluing material of past
times. Its various uses can be traced back far into the prehistoric epoch of mankind.
95
Archaeometry '98, Budapest
Birch bark contains a concentrated form of the triterpenoid betulin which, next to lupeol may be considered a
characteristic extractive of birch bark. Hence, the lupane derivatives betulin and lupeol are bio-markers which
reveal the biological origin of archaeological pitches carbonised at low temperatures. While birch tar or the
pitches formed thereof in the ageing process contain both betulin (lupendiol) and lupeol, the relative
percentages of these substances depend greatly on the way the smouldering process had been carried out. In GC
analyses only the gas chromatograms of birch tars obtained by gentle methods (smouldering temperature below
350 °C) show characteristic peak profiles, with a dominant betulin peak.
There are changes in the relative portions of the triterpenoid lupane derivatives as well as in the components
themselves whenever birch tar had been produced at excessive temperatures (above 350 °C). Betulin, above all,
is either reduced or absent altogether. The resultant peak profile of the birch tar shows considerable variations
from the expected pattern and in this case is characterised by degradation and conversion products. Betulin and
lupeol are degraded to give lupadienol and lupadien respectively, with a concomitant setting free of water. The
bio-markers are thus replaced by degradation-markers which reveal the extent to which the pitch had been
exposed to heat.
Generally, the role of betulin as a bio-marker in the identification of birch pitch is overrated, in particular in the
case of pitch finds exposed to greater than normal heat either during production or in the course of their being
used. Regardless of site and age of the prehistoric finds, both kinds of birch pitches were found, i. e. they either
contained or lacked betulin.

Expert system are computer programs that contain knowledge base, inference engine and user interface.
Knowledge base consists of formalized knowledge, and partially, of intuition employed by an expert in his
reasoning about particular problem. When this knowledge is acquired an expert system user can pose questions,
while inference engine brings up conclusions that are presented in a multimedial manner through user interface.
It is especially significant that an expert system should be capable to explain the way it reached answers, so that
inferred conclusions could be confirmed, and a mode of reasoning could be illustrated.
Applications of an expert system depends on the contents of its knowledge base. We suggest that the
archaeological knowledge is suitable for formalization, and that it is possible to produce useful expert systems
for archaeology.
We represent an actual expert system called PANDORA through several examples, as well as the experiences
acquired during its development. In our opinion PANDORA can be used as a consultant of explorers, as well as
an education means by which an expert work could be represented to students.
152. Mapping of the archaeological facts
Kovalevskaia V.
Institute of Archaeology RAS, Dm Ulyanova 19 117036 Moscow, Russia
In pre-revolutionary Russian and international archaeology, interest in the systematization of materials was very
closely interconnected and its streamlining in a time-space continuum was very significant. The 60s in our
country marked the beginning of the mathematical analysis of the basis of source studies: namely at this time
the question was placed of the necessity of mathematization, the introduction of objective criteria for the
resolution of questions of similarity and difference, the creation of a generally accepted scientific language and
rules of description, analysis and interpretation (V.B. Kovalevskaia (Deopick) 1961, 1965, I.S. Kamenetsky
1965, B.I. Marshak 1965, G.A. Fyodorov-Davydov 1965, Ya.A. Sher 1970, D.V. Deopick 1970). It's natural
that in archaeology the temporal and territorial affixation of artifacts, monuments, and archeological cultures
vary, the level of their complexity, heterogeneity, the rate of evolution of their components, and so forth, that is
all the parameters in their endless variety. But the model and approaches are unified enough so that one general
96
Archaeometry '98, Budapest
procedure of investigation can be used for different material, taking into account all the possible variation of the
applied methods. Time and space are a basic notions in archaeology while the definition and superimposition of
distribution areas were hitherto the main techniques of spatial analysis in traditional archaeology. The
introduction of computational genogeographic mapping, elaborated by prof. Ju. Rychkov, to archaeological
materials has greatly enhanced the possibilities of archaeological researches. With the use of the continuous
interpolation function (spline-interpolation, average weight interpolation) it became possible to create
quantitative models for the distribution of a number of leading forms of mass archaeological materials and
compare them. Early Iranian migrations, Hun invasions, "great migrations" of antic and early medieval time
have been investigated with the aid of computational programs GGMAG, Datstat, Mapstat. The method allows
one to create cartographic patterns of the distribution of the main types of artefacts throughout the archeological
cultures under consideration (center/periphery, "diversity-in-unity"). In conjunction with historical,
anthropological and genetic materials, a generalised maps show the movement of several groups of peoples in
Europe (first mil. B.C. - first mil. A.D.) by aid of archaeological material.
153. Geophysical Survey and its Verification on Archaeological Sites in
Bohemia

The most intensive and systematic co-operation between geophysics and archaeology including another nondestructive methods has been carried out in Bohemia since the 1990s when started the rapid increase of
landscape changes and importance of rescue archaeological excavations. Geophysical methods were in the last
years used not only for preliminary archaeological prospection of sites but some of them were used also in time
of open excavation or for detailed survey of previous studied or excavated sites. The examples presented in this
report shows comparison of results of magnetometry and archaeology or efficient use of combination of both
methods on various types of archaeological sites. An example of systematic survey of hill-fort Cimburk by
Bylany in Central Bohemia showed that by gradient magnetometric survey of area near the edge of previous
excavated place we could identify continuing of different types of Eneolithic, Hallstatt and Early Mediaeval
fortification. An example of detailed survey of North Bohemian glass-working High Mediaeval site Kyjov
demonstrate that by different types and amplitudes of positive magnetic anomalies we can identify glassfurnances, glass-waste heaps and other features before archaeological excavations. Another example from North
Bohemia shows application of detailed survey of prehistoric rectangular tomb near Cernoucek where various
amplitudes of intensity of magnetic field separate dark soil filling inside of ditch and stony filling of central
grave by massive neovolcanic blocks. Interesting results brought magnetometric survey of area near Central
Bohemian Vinor where two very similar ditches documented during previous rescue archaeological excavations
of pipe-line in distance 55m creates a Neolithic circular enclosure.

region of Varna (Northeastern Bulgaria) were additionally investigated.
The analysis of IR-spectra and comparison with reference spectra of amber from Baltic region (succinite),
Switzerland and Austria (plaffeite) proved:
- the archaeological amber from West Thracia (West Rhodopes and Vardar river), and the majority of Roman
amber 813 samples) have Baltic origin.
- all other investigated finds are not succinite

155. Raw Material Sources and Ceramic Production in LBA Central
Macedonia, Greece: A Comparative Analysis of Handmade and Wheelmade Pottery by Thin Section Petrography

During the second half of the second millennium, two ceramic traditions, technologically and stylistically
distinct, co-exist in Central Macedonia, Northern Greece. One relates to the manufacture of plain domestic, and
some decorated, handmade wares and has a long history in the area. The other comprises a newcomer and its
products, mainly wheel-made decorated table ware, appears with growing frequency after the 15th century BC
and follows closely the Mycenaean style.
The present project aims to shed some light on the complex picture of pottery production in the area, focusing
on the study of the ceramic assemblage from the site of Toumba Thessalonikis. Comprising a detailed
typological and technological study combined with the thin section petrographic analysis of 300 pottery samples
and the systematic research on the local clay sources aims to characterise the raw materials used and investigate
their provenance, understand the technological processes and the organisation of ceramic production and,
finally, relate them to the functional and typological characteristics of the pottery.
Three major "local" groups and some minor, not distinctively "local" ones, have been identified among the
handmade vessels, on the basis of mineralogical composition and manufacturing technology. This distinction
partly coincides with the main pottery functional groups: pithoi, cooking pots and table ware. Referring to the
wheel-made pottery, despite limitations imposed by its technological characteristics and the fine quality its
fabrics, macroscopic study and petrographic analysis have observed considerable variability in the materials
used. The relationship of this variability to provenance, date, typological and technological differences is
discussed.
The variable degree of internal homogeneity and standardisation within the various groups in terms of each
potting tradition, seems to reflect different degrees of craft specialisation, indicating that different types of
pottery were produced under different modes of production organisation, even within the same geographical
area.

Objectives
In 1996 a Roman cemetery (1st - end of 4th century) was uncovered near Hegyeshalom (north-west Hungary).
Excavations were directed by András Figler, Mosonmagyaróvár Museum. Among the finds there were several
bronze and silver brooches, exact composition of which had to be determined. Based on the PGAA
measurements, archaeologists hope to get useful information about the findings (e.g. different manufacturing
processes, different dates of origin). The lack of alternative non-destructive analytical methods emphasises the
importance of PGAA.
Method and results
24 brooches were examined (both early and late types. Two of them made of silver, the rest made of bronze.
The same part of the samples were irradiated for 1000 seconds. The sample chamber was not evacuated.
98
Archaeometry '98, Budapest
The main alloy components were identified by their prompt-gamma rays, originated from nuclear reaction. The
Cu-, Zn- and Sn-ratios were determined with k0-method.
Three groups of bronze samples can be distinguished. Most of the samples contain 92-98 (10 % Cu and 2-8 (1
% Zn. The second group of samples contains also 4-6 (1 % Sn, and the third one contains Cu, Zn, and Sn.
We were also able to detect some trace-elements, like Mg, P, Cd and several rare-earth elements, which
possibly originate from the soil, contaminating the surface. Further analysis of trace-elements may give more
useful information.
157. Towards a Radiocarbon Chronology of the Romanian Prehistory
Attila László
"Al. I. Cuza" University, Iasi, Romania
Viewed, at the beginning, with doubt by archaeologists, starting with the 70's the radiocarbon dating gradually
gains in importance also in the Romanian prehistory. For the time being, we have more than 200 radiocarbon
dates, obtained from various European or American laboratories, Romania being one of the few European
countries without a radiocarbon dating facility. Unfortunately, these dates unequally cover the various
prehistoric periods and cultural areas. Thus, the almost 80 14C dates for the Palaeolithic and Epipalaeolithic
regards exclusively the regions situated east or south of the Carpathians. Concerning the Neolithic and
Eneolithic ages , with approximately 100 radiocarbon dates, we have the same situation: the Transylvanian
cultures dispose of no more than few dates. The other about 20 14C dates refer to the so called transition period
from the Eneolithic to the Bronze Age, and, to a smaller extent, to some of the Bronze Age cultures.
In the last decade, as regards the post-Palaeolithic civilisations, besides conventional 14C dating, the usage of
calibrated data was initiated too, working especially with the calibration program of M. Stuiver - P. Reimer.
The paper proposes a discussion of the radiocarbon dates regarding Romanian prehistory (Middle Palaeolithic Bronze Age, ca 50000 BP-3100 BP/1435-1313 BC) in the context of the south-east European prehistoric
chronology.

The copal resin has been widely used in Mesoamerica since Prehispanic time as a key element in ritual and
domestic activities. Numerous historic and ethnographic References describe that the copal resin was employed
not only in the ritual context, but also in the preparation of varnish and adhesives. However, the presence of
copal residues in archaeological materials has been scarcely studied because of several methodological
problems.
In this paper we present a method to identifying the copal resin from ancient objects by solvent extraction and
gas chromatography/mass spectrometry (GC/MS). A method is described here that use a shorter extraction time
and whose resulting yields are favourably compare with other methods. The method was applied both modern
copal resin and Mexican archaeological materials such as copal figurines and ceramics. The results show that
this method should be a useful tool for artifact-use determination.
159. Structural studies on the metallic artifacts of Phrygian period
Ercanli, Levent
PK 146, Maltepe, Ankara Turkey

Archaeometry '98, Budapest
The Phrygian metallic artifacts obtained from the excavations and tumuli in the vicinity of Ankara were initially
examined from a purely archaeological point of view. Recently however, some of the metal findings were
subjected to study through the application of physical and chemical analysis. The results have led to a reexamination of original conclusions drawn from the archaeological evidence.
In this study, we present some of the results which have been obtained through metallurgical analysis such as
optical and scanning electron microscopy. Both techniques were used to reveal detailed structural analysis of
artifacts which will give the production technologies of these objects. Also X-ray energy dispersive analyser
was used to obtain microchemical analysis of the objects.
A characteristic feature of the external corrosion layer was the formation of a cuprite layer covered by a scale of
malachite. From analytical evidence, the corrosion layer is practically devoid of tin. In the surface corrosion of
tin bronze, copper is thus selectively attacked resulting in the formation of cuprite. As corrosion proceeded, the
copper oxide was transformed from the outside into basic copper carbonate (malachite) through the action of
CO2 and H2O present in the environment.
Most of the pieces investigated exhibit a recrystallized microstructure with annealing twins. This suggest that in
processing of these artifacts, the deformation (hammering) of the starting material was followed by an annealing
treatment above 550 °C.
The numerous precipitates and inclusions which occur in the metallic core were apparently already present in
the starting material in the form of impurities.
160. Semifinished products for glass-making used in the Antiquity and the
Middle Ages
Julia A. Likhter
Center of Archaeological Research, Pyatnitskaya Str. 19 113095 Moscow Russia
Written sources describing the Ancient glass-making are well known. But there are no answers to some
questions: the structure and organisation of craft, the types of workshops. One of such questions refers to
existence of workshops with an incomplete production cycle. Having no description of working methods used
by craftsmen we have the results of their work - the artefacts they produced. An artefacts is a valuable source of
information about its maker's know-how, and about the organisation.
From this point of view a great number of glass beads, vessels, armrings and fingerrings were investigated. We
can connect same of them with different semifinished products - tubes, rods, halfspheric cakes.
Working with them characterises workshops of different levels. Insertion of glass sherds in non-glass artefacts
is the first stage of working with the new material. It was the production of barbarian craftsmen. Next stage working with simple semifinished products as cakes and rods. This is the first step in mastering the glassmaking craft. Probably this refers to craftsmen, which were included in the sphere of influence of the Roman
Empire. Working with tubes needs much wider knowledge in glass-making. Craftsmen having such knowledge
were probably connected with classical regions of glass-making.
We can suppose also where semifinished products themselves were made. Mosaic strips came from Egypt,
tubes from East Mediterranean and Northern Mesopotamian. Rods and cakes may be connected with these
centres, but also with Rome, its European provinces, and afterwards with Byzantium as Rome's heir.

The detailed study of archaeological activity areas is now commonly carried out through advanced chemical and
physical analysis. These techniques are designed to detect soil properties which have been enriched or altered
by human activity. Soil color is a common descriptive property used to characterize and differentiate
archaeological soils, but which lacks a clear relationship to the underlying chemical and physical composition.

Archaeometry '98, Budapest
The visual (and subjective) determination of observed color by comparison with the Munsell Soil Color Charts
is subject to substantial errors due to several psychophysical and physical factors. Another limiting factor is that
Munsell data derived from systematic sampling is not readily converted into quantitative data for spatial
visualization. Soil color can be characterized by its spectral reflectance curve, and then converted into
tristimulus values (CIE Lab) in a perceptually uniform color space. Small differences in soil color can then be
used to identify and study differences in compositional properties and cross correlated with electrical and
magnetic geophysical data. This analytical methodology will be illustrated through the analysis of the lime
plaster floors from the post-classic period in the Hall of the Eagle Warriors, Templo Mayor of MexicoTenochtitlan.

Medieval Silver Coins by Energy Dispersive X-Ray Fluorescence Analysis

Increasing trade at the beginning of the 12th century AD in Europe implied new currencies with a wide range of
validity. One of these new legal tenders in the area of Carinthia, a Southern part of Austria, was the Friesacher
Pfennig. The first silver coins were struck by archbishop Konrad I. v. Abensberg (1106-1147) in the town of
Friesach. Caused by its big financial success the area of circulation had spread from Carinthia to North-Italy,
over Croatia and Hungary up to Slovakia. The big demand for this new currency yielded to a big number of
mints and even copies were produced during this period.
Coins of the early period, which are very rare and of a high value, have no marks or punches, by which
numismatists could classify the coin's mint. Therefore, non-destructive analysis by energy dispersive X-ray
fluorescence analysis was carried out. The aim of these investigations was to set up a library of the chemical
compositions of the alloys used for the production by the various mints. The silver coins, which were coated
with a layer of wax for conservation reasons, were cleaned with white spirit and ethanol in an ultrasonic bath
prior to analysis. The major elements silver and copper have been quantified by using silver-copper-standards,
whereas the trace elements such as Fe, Au, Pb, Bi, and Hg were determined by their X-ray intensities. As most
of the coins have been found in soil, where they have been buried for hundreds of years, leaching effects
occurred and caused big problems during the interpretation of the results. However, calculating the ratios of AgKa/Ag-L intensities decisions could be made, whether the coins were depleted especially on Cu on their
surfaces or not. For the interpretation of the data multivariate statistical methods like cluster and factor analysis
were carried out. Cluster diagrams and dendrograms enabled a clear and definite interpretation of the data.
The results showed that nearly each mint used its own technology or at least its silver ore for the production of
the silver alloys. By comparing the data of unknown coins with the analytical results of objects of known origin
it was possible to assign about 80% of these uncertain coins to one of five possible mints.
163. An industry in crisis? Changes in bronze composition bear the end of
the Hungarian Bronze Age

* National Museum Copenhagen, Marknesvej 26 2840 Holbe Denmark
**Max-Planck Institut für Kernphysik, Heidelberg
Changes in metal compositions at a late stage of the Central European Bronze Age are examined with a view to
looking for trends in composition at the Jungbronzezeit/Spatbronzezeit transition (close before 1000 BC.) on the
basis of a new series of 186 X-ray fluorescence analyses made at the Max Planck Institute. The objects are from
the Hungarian National Museum and Nyíregyháza Museum. Comparison with the published Stuttgart analyses
from the immediately foregoing period reveals several developments suggesting that the bronze industry was
facing problems.
1. Tin was in shorter supply and a substantial proportion of the artefacts were suddenly of unalloyed copper.
Occasionally the absent tin was replaced by large quantities of lead.
101
Archaeometry '98, Budapest
2. The impurity patterns suggest a tendency to breakup of the system of monopolistic metal production and
supply that had prevailed since the Middle Bronze Age.
3. Some of the copper/bronze is very impure, with values of up to 11.7% arsenic, 13.3% nickel, 9% iron, etc.
Such extremes are unusual and suggest problems in controlling the metallurgical processes.
It may be added that the ingots, furnace bottoms, slabs, drips etc. have usually been assumed to be melted down
scrap metal, but as most were of unalloyed copper this is an error. They must show a hitherto unstudied
intermediate stage in processing.

This work represents the conclusion of a long term study on a group of prehistoric metalwork comprised of
exotic copper-based alloys from the Carpathian Basin, and most notably, Hungary. The project focuses on a
previously little-studied area of archaeometallurgy, that of antimony bronze: copper - antimony alloys first
discovered in the Hungarian archaeological record some 100 years ago. The current study considers known
manufacturing centres, distribution, physical metallurgy and postulated reasons for its existence. The work is
based on examination of a corpus of archaeological material in conjunction with a series of laboratory produced
alloys. A suite of techniques have been used to illicit information on this select group of material, including
optical metallography, Scanning Electron Microscopy, X-Ray Diffraction, X-Ray Fluorescence, Neutron
Activation Analysis and mechanical testing. Conclusions drawn from the examination of high antimony objects
(e.g. >1% wt. Sb) indicate that the properties of this material were known, understood and selected for during
the Late Bronze Age, and that the predominant reason for the presence of elevated levels of antimony was due
to its use as a colorant.

Radioisotope excitation X-ray fluorescence analysis has been used to determine the composition of antimony
bronze objects found near Velem in western Hungary. Earlier, the XRF technique with I-125 isotope source
proved to be useful for analysis of late Avar bronzes where the amount of antimony was low or negligible. The
problem of analysis of antimony with this method lies in the high spectral background caused by the
incoherently scattered TeKa exciting radiation. Especially at low Sb level a not carefully performed spectrum
evaluation procedure may lead to false results. Both the spectrum fitting method and the fundamental parameter
method of concentration calculation have been tested by the analysis of the set of reference materials produced
at the University of Bradford UK. The analyses of these samples have also been performed by a secondary
target X-ray tube excitation system, where the antimony peaks can be measured without affecting by disturbing
backgrounds. Acceptable agreement of the analytical results with the composition of ingots has been obtained.
The composition of Velem findings are also given.
166. Provenance studies at Neolithic to Bronze Age pottery ware from the
Castel Grande (Bellinzona, Ticino, Switzerland)

Archaeometry '98, Budapest
The pottery which was found in the Castel Grande during excavations by P. DONATI in the years 1980-1984
provides a unique possibility to look into Early Middle European history. A very exact typological seriation by
R. CARAZZETTI showed that the ware represents a complete sequence from the Early Neolithic period (~5300
B.C.) to the late Bronze Age (~1400 B.C.).This suggests a permanent settlement of the area around Bellinzona
for a period of about 4000 years and makes it possible to study the development of pottery technology and
changes in used raw materials.
For the provenance studies two different methods have been used.
The temper analysis was used to determine if the rock and mineral fragments in the sherds are of local origin.
To do this, petrographical methods such as polarisation microscopy with quantitative mineral analysis have
been used. The first results of these studies show a good correspondence between the rocks of the Castel
Grande(gneisses, coarse amphibolites) and the materials which were found in the ware.
Chemical mineral analysis for main and trace elements of some typical minerals like amphiboles, feldspars and
micas with the EMP (electron microprobe) and the SEM (scanning electron microscope) are used to verify this
results.
The second method was a geochemical analysis of the sherds, local clays and rocks by XRF (X-ray fluorescence
analysis) which was used to compare the ware of the different periods and the supposed local raw materials.

In north-western Alaska chert artifacts are commonly the only surviving prehistoric relics. In this part of eastern
Beringia chert sourcing is crucial for determining the routes of human expansion into the New World. We
introduce the geological-geochemical approach to chert sourcing and illustrate it with the results of prehistoric
chert sourcing in north-western Alaska.
The geochemical approach includes constructing a database of mineralogical and geochemical signatures of
outcrops that can be then be compared with signatures of any artifact. The method is based on the idea that both
the artifact and outcrop have identical geologic history: depositional environment, provenance and diagenesis,
that are characterized with unique geochemical and mineralogical signatures. Analytical techniques involve
instrumental neutron activation analysis for detection of trace element and electron microprobe analysis
combined with X-ray diffraction for identification of mineral inclusions.
Four prehistoric chert quarries were identified in the western Brooks Range by comparison of 12 chert varieties
sampled from 9 outcrops with 289 artifacts from 55 prehistoric sites (representing all known in the area
prehistoric traditions dated from 10000 BP. to recent). Maps of distribution patterns of cherts mined in the
western Brook Range and found as artifacts in north-western Alaska prehistoric sites delineate prehistoric group
contacts and travel routes in the westernmost part of eastern Beringia. They show: 1/ direction and distance of
transportation from to quarry for each chert variety, 2/ during which prehistoric culture each variety was mined
and distributed, 3/ what chert varieties were preferred by different prehistoric groups.
The geological-geochemical approach to chert sourcing is generally applicable.
168. Provenance of White Marble with EPR Spectroscopy: Further
Developments

EPR spectroscopy has been proved to be a powerful tool for marble characterisation and provenance
investigation since it was first applied in marble samples, in the early 80's. An extended databank has been
created in the Laboratory of Archaeometry during the last ten years, with the EPR parameters for the most
important ancient quarrying sites: Penteli, Hymettus, Naxos, Paros, Thassos Aliki, Ephessus, Afrodisias,
103
Archaeometry '98, Budapest
Proconnesus. The results of an attempt to discriminate between these quarrying regions are presented in this
work.
The advantage of EPR spectroscopy over other analytical techniques, is that more than two parameters can be
used for discriminating between different quarries. Except for Mn2+ concentration in the calcitic and dolomitic
lattice, EPR gives many other parameters characterising the lattice structure and the presence of impurities.
In combination with EPR spectroscopy the Maximum Grain Size (MGS), determined easily with an optical
microscope, proves very useful for quarry discrimination.
The method which is developed for provenance determination is based on a stepwise approach. A first
discrimination is obtained using the Maximum Grain Size and the Mn2+ concentration of the samples.
Overlapping areas occur between Naxos Melanes and Naxos Apollonas, Paros and Proconnesus and Paros and
Hymettus quarries. A second discrimination stage follows, where overlapping areas are eliminated or at least
decreased for the problematic quarries. Naxos Melanes and Naxos Apollonas are clearly discriminated using
linear combinations of Maximum Grain Size, Mn2+ concentration and the intensities of the peaks at g=14.25 and
2.0044. Another successful discrimination is obtained between Hymettus and Paros, using a combination of
Maximum Grain Size, Mn2+ concentration and the intensities of the peaks at g=1.9998 and 2.0044. The results
are not so promising for the case of Paros and Proconnesus since most parameters overlap to a great extent. The
famous Lychnites marble of Paros, quarried underground is however clearly distinguished.
169. A Technological Investigation of 12th Century Mosaic Icon tesserae
from the Mount Athos, Greece

**Direction of Conservation of Antiquities, Ministry of Culture, Dioskouron 4, 105 55 Athens, Greece
A sequence of tesserae from two mosaic icons depicting St. George and St. Demitrios were investigated. The
icons are kept in the Monastery of Xenofondas on Mount Athos at Halikidiki, Greece and are assumed to have
been made in the 12th century AD.
The tesserae have a range of different colours such as, green, sky-blue, navy-blue, purple, black, red, brown,
pink, yellowish and white. Also, there are tesserae with gold and silver colours. All different coloured tesserae
were studied using, optical microscopy and scanning electron microscopy with energy dispersive microanalysis
both at fractured and polished sections.
The results indicate that all the pieces apart of those with pink, yellowish and white colours are made of glass.
The non-glass tesserae seem to be made of natural stones, like limestone or magnesium ores but they need
further investigation for a full characterisation. The glass tesserae can be divided into two groups: 1) the lead
glass ones, which have sky-blue and green colours, and whose colours are due to ions of Cu and Sn. The
relative variation in the concentration of these two ions give the colour changes between light blue and green. 2)
the non-lead glass ones, whose colours are dark-blue, black, purple and red with black striations are basically
sodium glass. The dark-blue colour is due to Cobalt, the black is based on Mn-Fe minerals, and the purple is
based on Fe-minerals as well as Mn-minerals, the intense red is a Cu based colour but the black striations are
rich in Mn-Fe minerals. The gold and silver tesserae are made in a rather clear or slightly tinted glass by using
gold and silver sheets of about 2 μm thickness and of very pure quality. The silver and gold sheet is covered by
another layer of glass for translucency.
The work continues with more SEM analyses and selected XRD in order to clarify certain remaining questions.

Pharaonic faience is familiar to many by its crude shape, thick walls, and deep turquoise blue color. Its
manufacturing technique has well been established. However, stylistic and technological changes took place
104
Archaeometry '98, Budapest
with Egyptian faience produced in the Ptolemaic period (300 BC-30 BC). Ptolemaic faience is known to have
been produced in the Delta region of lower Egypt, and has unusual features which distinguish it from pharaonic
faience made in the earlier periods. These characteristics include: refined shape, thin walls, two toned glazes in
contrasting colors, and detailed low relief surface decorations arranged in friezes. Very few faience samples of
this period have been analyzed and their methods of manufacture have not yet been completely studied. The aim
of this study was to characterize the materials and methods of manufacture of a group of this type of faience in
the Walters Art Gallery. A total of twenty two fragments and vessels were studied. A number of analytical
techniques were employed: stereomicroscopy, X-radiography, Xeroradiography, X-ray
fluorescence
spectroscopy, and scanning electron microscopy-energy dispersive spectrometry. The research results aided in
the identification of body type and glazes used during production, and the explanation of fabrication
techniques.
171. The Petrology of Iranian Safavid Ceramics
R. B. Mason, L. Golombek
Near East and Asian Civilizations, Royal Ontario Museum, 100 Queen's Park, Toronto, M5S 2C6, CANADA
During the Safavid period (1501-1732 AD) Iran saw the last of the great periods of ceramic production in the
Islamic world. Wares were predominantly influenced by Chinese imports, particularly during the production of
the "Kraak" wares widely traded from China in the seventeenth and early eighteenth century. Other important
types included wares decorated with the traditional Islamic metallic overglaze lustre-paint, and polychrome
underglaze-painted wares only distantly related to Chinese influence.
This is one of the last of the great periods of production of pottery in the Islamic world for which knowledge of
the sites of production is not based on hard scientific evidence. Petrological studies of earlier wares of the
Islamic world generally indicate very few highly specialised production centres for pottery of the highest quality
(Mason 1995, 1996). This study is aimed at defining the characteristics of the Safavid wares, and eventually
linking these characteristics to specific production centres.
Analysis of the available Safavid wares has produced four distinct petrographically-defined fabrics
(petrofabrics) which generally relate to discrete stylistic groups. All are stonepastes, and so the criteria for
characterising these quartz-rich ceramics has been applied (Mason 1995). None of the groups are identical to
petrofabric groups defined for production centres identified in studies of earlier wares. No kiln evidence has
been included in the samples, but there is historical evidence of production at a number of sites which can be
related to the spatial distribution of the petrofabric groups. Hence two of the groups are tentatively attributed to
Kerman and Mashhad.

172. Beads from the North Caucasian Klin-Yar-III. cemetery (the 5th-8th
cc. AD.). A chemical-technological analysis
Anna Mastykova
The Rescue Archaeology Dept. Institute of Archaeology, RAS, Moscow, Russia
The sites of the Kislodovsk hollow are of great importance for the study of North Caucasian archaeology.
Among them the so-called Klin-Yar-III. cemetery stands out. The finds recovered from this site enable one to
study a number of issues pertaining not only to the Kislodovsk area but to the whole of the North Caucasus. The
present paper deals with the use of such a category of the archaeological record as excavated beads for the
periodization of the site in question and for a more accurate dating of funerary complexes.
We have examined glass, jet, amber and carnelian beads recovered from 10 catacombs of the Klin-Yar-III.
cemetery. Their morphological analysis has shown that a given time-span can be invariably associated with a
certain technology of glass-making and a certain ratio of glass and stone beads.
A quantitative spectral analysis has shown the presence of the following types of alkaline glass:
105
Archaeometry '98, Budapest
a/ Si-Na(K)-Ca(Mg) being the main type
b/ Si-Na-Ca
Compounds of copper, manganese, iron and cobalt turn out to have been used for staining.
The study enables us to surmise that the glass beads under investigation are of Near-Eastern origin and their
influx to the North Caucasus had been relatively stable, though in the mid-late 6th c. AD. then in the mid-late
7th c. Ad and in the first half of the 8th c. AD. new types of imported beads replaced the older ones. This fact
can be accounted for by the establishment of new trading links indicative of changes in the economic priorities.
173. Strangers in a Strange Land? Renaissance Glass-making in
Amsterdam
W. Patrick McCray
Dept. of Materials Science and Eng. College of Engineering, University of Arizona, Tucson, AZ 85721, USA
Based on archaeological excavations and archival material, glass was primarily a luxury item before about 1575
in Amsterdam. Within the next 50 years there was a shift with respect to the appearance of glass in different
levels of society due to the changing role of Amsterdam in the world-economy. In the late 16th century, there
are archival records which record the presence of Italian glass-makers at the first known glasshouses in
Amsterdam. Eventually, it and other Dutch workshops employed many Italian workers including émigrés from
Venice to make facon de Venise glass.
This work examines the transfer of glass-making technology from Italy to Amsterdam. There are many different
sources of information that can be used to understand glass-making technology-written sources, pictorial
representations, and studies of the glass itself. This paper integrates this information to provide a fuller picture
of glass as it was made and used in Amsterdam.
Glass samples from several late 16th and early 17th century sites in Amsterdam were examined and analyzed.
Chemical analyses were carried out with a variety of techniques including SEM-EDS, WDS, and ICP-AES.
These results will be compared with analyses of Venetian glass from the same time period. In this manner, the
adaptation of Italian/Venetian glass-making technology to local Dutch tastes, within the limitations of the
available raw materials, will be examined. It will be shown that émigré glass-makers adjusted remarkably well
to their new working circumstances in terms of making a glass that was aesthetically unique yet compositionally
similar to that produced in Italy.
174. The complexity of copper mineral acqusition in the Aegean, Third
Millenium BC.
Veronica McGeehan
The Open University, Eldon House, Newcastle upon Tyne NE3 3PW, UK
The objective of this paper is to analyse further the complex nature of copper mineral acquisition and
exploitation in the Aegean during the Third Millennium BC. Particular emphasis will be given to the
implications for the Helladic metal industry.
The initial problem which motivated this ongoing study was the need to identify which copper sources were
exploited by the EBA mainland Greek industry in order to assess whether or not it developed autonomously.
In this paper, new data which helps us assess the copper sources available to, and in, the Aegean region is made
available through an up to date evaluation of the latest geological data, lead isotope results, chemical analyses
and typological data for mainland Greece, west Anatolia and the Aegean.
The results serve to further enhance our understanding of the nature of copper acquisition, the extent of trade
and exchange and the impact this had on the development of mainland Greek metallurgy in the third millennium
BC.

Hungary

West Hungary, especially the middle part of Transdanubia, the surroundings of the lake Balaton is one of the
best investigated territory of Hungary from palynological and archaeological point of view.
In this work we collected the published pollen data of the last 50 years completed with very new analysis dated
by C-14 method.
Our aim was
- to detect the changes in the pollen diagram caused by the human activity: forest clearance, animal husbandry,
plant cultivation
- to observe the first occurrence of anthropogenic indicators (cereals and ruderals), the changes their quantity
and quality compared with the cultural landscape development from the Neolithic Period until the Middle Ages.
- to compare the changes in the pollen diagrams with the settlement structure (number and character of the
settlements) of the different archaeological periods.
- to compare the changes of the AP and NAP ratio and of the components of the pollen spectra comparable to
different stages of the land-use history.
This paper is a part of a long term research, the first attempt to demonstrate by the pollen analytical record the
development both of settlement and of land-use techniques in Hungary.
176. Estimating Age at Immigration: A Theoretical Model Using Strontium
Isotope Ratios and Differential Bone Remodelling Rates in Various Skeletal
Elements
William D. Middleton,T. Douglas Price
Laboratory for Archaeological Chemistry, University of Wisconsin-Madison, 1180 Observatory Drive, Madison Wi 53706
The use of strontium isotope ratios in calcified human tissues has become a powerful tool for identifying
prehistoric residential mobility. Because tooth enamel forms during childhood and remains unchanged, while
bone remodels throughout an individual's life, a difference in the 87Sr/86Sr ratio between tooth enamel and bone
indicates a change of residence. Different skeletal elements, however, remodel at different rates throughout an
individual's life span. After migration, skeletal elements will vary in their isotopic composition proportionate to
the rate of bone turnover. These differences should make it possible to estimate the age at which an individual
migrated. This was tested by computer simulation, modelling the effect of differential bone turnover on the
isotopic composition in four skeletal elements (anterior and posterior iliac crest, rib, and mid-shaft femur). Two
sets of 2000 simulated individuals, who moved and died at different ages, were generated. The first set was used
to calculate a discriminant function for predicting the age at time of move, which was tested on the second set.
The actual versus predicted age at time of move was correctly identified in 95% of the cases. The simulation,
while still untested against empirical data, suggests an exciting new direction for the use of strontium isotope
ratios in archaeometry.

Forty glass fragments were studied by scientific techniques of investigations. Most samples were fragments of
chalices, lamps and window glass with colour ranging from blue to blue-green, green and yellow-green; other
samples represented opaque decorative inlays coloured white, light-blue and red. The fragments, dated to the
seventh century AD, had been found in the course of archaeological excavations carried out in the Crypta Balbi
in Rome; their study aimed at obtaining information on the level of technological knowledge left in Rome and
the regions trading with Rome after the fall of the western Roman Empire.
The composition of the fragments was obtained by ICP atomic emission spectroscopy, determining 22 elements,
including major, minor and trace elements. In addition, reflectance spectroscopy was used to collect information
on the presence of colouring agents, and X-ray powder diffraction to investigate the presence of opacifiers in
the opaque inlays.
All the samples resulted to be soda-lime glasses, with low contents of potassium and magnesium; this would
point to the use of a natural deposit of soda, rather than plant ash, as a source of flux. Cluster analysis and
principal component analysis performed on the analytical data further indicated that several batches had been
used to obtain the studied objects; this would result from the use of different raw ingredients or their mixing in
different ratios, indicating various provenances or a technological differentiation within these glasses.
Iron(II) and iron(III) ions were found as the main colouring agents in the blue-green, green and yellow-green
fragments, whose actual colour depends on the total iron to manganese ratio; total concentrations indicate
deliberate addition of the two elements in about half the samples. Cobalt(II) was the main colourant in the blue
glasses.
Copper was found as the colouring agent in the red and the light-blue opaque fragments; X-ray diffractograms
suggest the presence of elemental copper rather than copper(I) oxide as the opacifier, besides colourant, in the
red sample, and of calcium antimonate in the white and light-blue fragments. No evidence was gained on the
use of tin compounds as opacifiers. However, the level of tin in the copper rich fragments suggests the
introduction of the colouring agent through a copper alloy.
178. The Contribution of Colour Measurement in Studying Provenance
and Technology of Ancient Pottery
Piero Mirti*, Patrizia Davit*, Enzo Ferrara**
*Dipartimento di Chimica analitica, Universitŕ di Torino, Italy
**Istituto Elettrotecnico Nazionale “Galileo Ferraris”, Torino, Italy
Colour measurement may be used to study provenance and technology of ancient pottery. In fact, colour coordinates of fired clays change with temperature, time and atmosphere of firing. This may allow to assess firing
temperatures of ceramic materials fired under oxidant conditions, as the colour of refired sherds may not change
until the equivalent temperature of firing (Te) has been exceeded. In addition, colour change after having
surpassed Te depends on the clay used and may aid in tracing back provenance.
The method, previously tested on clay samples, was first used to study firing conditions of red gloss ware
(Roman terra sigillata) from north-western Italy. Here, different temperatures of firing in the range 800-1000 °C
were evaluated for wares of different provenance (Gaul, north and central Italy) and different quality; the
obtained Te were in agreement with those inferred by X-ray diffraction.
Subsequently, colour measurement was used in the study of transport amphorae and black gloss ware
(Campanian pottery) from ancient Calabria (southern Italy). Firing temperatures of about 600-700 °C were most
frequently inferred for transport amphorae; this enabled to follow colour change with temperature in an upper
range up to 1100 °C. It was found that amphorae of suspected local production could exhibit different
behaviours, in agreement with the information provided by the chemical composition, which suggests grouping
in different classes.
Colour graphs were more difficult to interpret in the case of Campanian pottery. However, an interesting result
was obtained for sherds of Campana A, which displayed a similar behaviour. This would point to the use of the
same clay and to a standardised working procedure, as was probably the case for pottery of this kind produced
in the Naples region.

Samian ware from Argonne has to be considered as a real 'guide fossil' in the knowledge of Late Roman time in
North Gaul. This ceramic actually spread the market with a somewhat monopoly in Gaul. Its main diffusion
area is located between the Seine and Rhin rivers from their springs to the sea. Moreover, a wider diffusion,
even though more restricted, also occurred from the French Pyrenees to Hungary (Balaton Lake), and even in
Ireland. Beside Argonne, other late Samian ware productions are also reported in Gaul, but their diffusion was
less important. Furthermore, other local related productions known as Dérivées de terre sigillée, have been
excavated in the Paris Basin and in the NW of Gaul.
The sampling of the research gathers wares from three workshops in Argonne, Domecy-sur-Cure workshop
(Burgundy), Rues-des-Vignes workshop (NW of Gaul) in connection with three other groups of this area:
Tournai, Bavay and Arras. Potsherds from Meuse valley settlements (Maastricht, Huy and Verdun) are also
included.
The recognition of each of these productions without any confusion is a crucial archaeological problem which
has to be coped by the means of mineralogy (thin sections, XRD) and chemical data (XRF) used for statistics.
Our research points out the own features of each production and estimates likely origin of settlement sherds.
Furthermore, microprobe analyses leads us to understand technological aspects of these wares pointing out the
refractory nature of the clays used for the surface finish and the body which is, moreover, non-calcareous. This
explains the bad quality of these ceramics.

Chemical analysis of pottery is a well method to achieve a classification according to production methods in
pottery workshops and provenance which in independent of archaeological classification parameters. As long as
the ancient potters did not change their production procedure with respect to chemical composition, all pieces of
such a production series will show the same elemental concentration profile and can be recognized by it.
As part of a project "Pottery production and distribution of Late Bronze Age (LBA) settlements of Greece and
the Aegean ' further 200 neutron activation analyses (NAA) of LBA pottery from Boeotia have been added to
our databank of already more than 2000 samples from different regions of Greece. The new samples stem
mainly from Thebes and Orchomenos. Multivariate statistical grouping of the data reveals several hitherto
unknown reference groups separable from groups of other regions of Greece and Crete. The results of the
samples from 10 Linear B inscribed jars found at Thebes and formerly analysed by emission spectroscopy
(OES) are of special interest. They form a statistically well defined group different from all the other groups
known to us, but can be assigned to an unpublished reference group of pottery from Chania, Western Crete, in
the LBA Perlman - Asaro databank of Greek Bronze Age pottery. The final results of the chemical classification
and the archaeological implications will be presented.

Previous INAA of 122 Cu/Co tinted blue glass trade beads from Ashuapmuchuan, combined with their
archaeological site locations, led to two main hypotheses*:
1) From a comparison with the elemental compositions obtained for beads from sites in Ontario and Québec,
these beads pertain to the late seventeenth century.
2) The sharp split into two chemical groups according to their elemental characteristics corresponds to the split
observed between the beads of one of the chemical groups being spread over a surface as opposed to the beads
of the other group that were found tightly packed together. The matching of the elemental groupings with the
archaeological locations suggested that the group of beads that was spread widely corresponds to the blue beads
of the decorative pattern sewn to a bag while the beads that were tightly packed together consisted of loose
beads in the bottom of that bag. Together with these blue beads were found 344 European white glass beads.
INAA of all these latter beads allows us to test both the hypothesis of the temporal assignment as well as that of
the anthropological interpretation of these beads as pertaining to a decorative pattern of a bag, itself containing
loose beads. Given a strong agreement of the results obtained for the white beads with those previously
obtained for the blue beads, this study results in a strong case of reconstruction of an ethnoarchaeological
behaviour pertaining to the field of cultural aesthetics, such an endeavour being among the most difficult to
attain in archaeology.

Slag-like material from a mound of uncertain origin near the town of Toranagallu, Karnataka, India was
analyzed with the purpose of determining its origin. The experimentally obtained temperature that was attained
in the vitrified sample exceeds those obtainable in open fire conditions. Analytical results suggest that the
material represents residue from a glass making operation. This result defines one use of the mound, but leaves
open the possibility that a range of other activities may have contributed to the mound's development.

The subject of our study were stone tools mainly from the Lengyel culture. The samples were obtained from the
Wosinszky Mór Museum, Szekszárd, Hungary.
The axes were found at the following localities: Lengyel, Mórágy, Dúzs, Szabaton, Tengelic, Nagydorog,
Szekszárd. Our main goal was to characterize and describe the raw material of the stone tools and to determine
the assumed origination place. We made detailed macroscopic and petrographic description on 21 axes.

The raw material of the instruments is very variable, among them there can be found magmatic, metamorphic
and sedimentary rocks such as basalt, andesite, hornfels and different types of limestones. Additional
investigation methods include powder diffraction analysis, neutron activation analysis, microprobe analysis and
optical emission spectrography. By the agency of these methods we try to localise the origin of the raw material.
Prehistoric men did not possess any means of communication or transport so long travels were hard for them if
not impossible.
According to our investigations we believe that the major part of the used material is confined to the AlpCarpathian region.

The amino acid (AA) composition of corals aged between 1 and 250 years, was analysed by ion exchange
column chromatography. It was established that the concentration (g AA/100 g sample) of all AAs decreased
with age; the greatest decrease was observed in those AAs which are particularly sensitive to environmental
influences (Thr, Ser, Cys, Met, Tyr, Lys, Arg). The concentration of His, Asp, Glu, Pro, Gly, Ala, Val and Phe
decreased with age, but the decrease in concentration of Ile and Leu was very small. These two amino acids are
the least sensitive to environmental influences. In the protein of the coral (g AA/100 g protein) it may be
asserted that the highest decrease can be observed in Thr, Ser and Tyr, which are very sensitive, and which
decompose very easily. The decrease was also significant in the case of Met and Cys, the two sulphurcontaining amino acids, which can be explained by the oxidation or conversion to other amino acids, or
decomposition. The decrease was very slight in the case of Asp, Pro and Arg, and there were no changes in the
concentration of Glu, Gly, Ala, Val, Phe and His in the course of 250 years. These AAs are not sensitive to
environmental influences. There was a minor increase in the concentration of Ile and Leu during this time,
which was surprising, but may be explained by the decomposition of other AAs, which caused relatively higher
amounts of these two AAs in the protein. Plotting the concentration of the AAs as a function of time, calibration
curves were obtained, which are useful for the age estimation of a coral sample of unknown age.

In this study bulk compositional data on a group of Iznik ceramics is reported. Samples are selected from the
materials excavated in 'Iznik Kiln Excavation' courses. The glaze, slip and body characteristics and the
microstructures of the sherds are determined by optical and SEM work.
Slip painted and Miletus ware of Iznik ceramics are made from red earthenware clays and some lead rich
inclusions are detected in their bodes. No trace of tin is detected in their alkali-lead type glaze layer.
The Iznik whiteware bodies are consist of ground quartz and a glassy matrix that bonds the angular quartz
particles together. The glassy phase contains variable amounts of lead oxide. The glaze is of the lead- alkali type
and have dissolved tin oxide in it.

Iron Age

Institute of Archaeology RAS, Dm Ulianova Str. 19, 117036 Moscow Russia
The greater part of the region between the Caspian and the Aral Seas is occupied by two plateaux, Usturt and
Mangyshlak. Until recently this strategically important zone which connects the South Ural region and the Front
Asia stayed practically uninvestigated by scholars. However during 1980-1990s numerous funeral and cult sites
which date back to the 2nd half of the 1st millennium B.C. have been found there by Russian and Kazakh
archaeological expeditions. Archaeological and paleoanthropological data which were obtained allows us to
make the first conclusions about ethnical and cultural peculiarities of the Aral and Caspian region population
during the Scytho-Sarmatian epoch. The characteristics of the burial constructions, funeral goods and
"Sarmatian signs" are the most significant features of the Sarmato-Sako-Massgetae' s circle of cultures. But the
round cult constructions and stone anthropomorphic statues which were discovered in the Usturt sanctuaries are
the very interesting and unique objects.
The results of anthropological and osteological researches are important to solve the problem of ethnic origin of
the region population. Three skulls from the burial sites of this époque were investigated in the Laboratory for
112

anthropological reconstruction of the Institute of Ethnology and Anthropology of RAS. Male skull (age 20-24)
from the burial dated III.-II. cc. B.C. in the cult construction of the sanctuary Teren is large, dolichran at the
limit of mesocran, the face is high and wide, nose protrudes considerably. Female skull (age 40-50) from the
grave near Sarykamys village dated I.c. B.C. - I.c. A.C. is characterized as large, mezocran, middle high, the
face part is wide, low, flat, mesoghnat. Male skull (age 55-60) from the Dykyl-tas cemetery dated II-III. cc.
A.C. is mesocran at the limit of brachicran, the face is high and wide at every level, some flat at the upper part,
altitude and the angle of nose protruziaon are great.
Three plastic sculptural portraits were reconstructed on the above mentioned skulls using the method of facial
restoration at the basis of skull enriched by the soft facial tissues thickness dates, obtained by the ultrasonic
technique on alive persons.
The restorated faces are characterized as europeoid with some mongoloid mixture which increases to our days.
The representatives of studied East Caspian nomadic population more close to Sarmatians of Ural region and
South Siberia than to East Aral region synchronic groups. That marks certain ethnogenetic contacts between the
populations of the mentioned regions at the end of the 1st millennium B.C.

Analysis of Anatolian copper and bronze artifacts show a wide range of minor metallic elements. Field research,
examination of mines, orestuff and smelting debris along with experimental smelts in the laboratory
demonstrate that polymetallic ores were smelted to win copper at widespread sites in Anatolia, using a one-step
smelting technique on predominantly sulphide orestuff, followed by refining. Archaeometallurgical material
recovered from the Merzifon region located in North central Turkey yielded results indicative of utilization of
polymetallic ores in the production of copper. The tradition of exploitation of polymetallic ores extends back in
to the Late Chalcolithic Period as is evident from a large number of such ores recovered from the Arslantepe
excavation at Malatya. Similarly an ore sample from Pre Uruk HacÝnebi stretches the technology to
Southeastern Turkey. Furnace design and smelting technology were critical to the success of smelting
polymetallic ores. Application of extensive refining methods on the impure copper to obtain workable copper
would also eliminate the critical arsenic which must be reincorporated into the copper at a later stage, for an
arsenical bronze. Investigations by AA and SEM/EDS support the conclusions drawn from field evidence. The
indications are that copper was sourced in Anatolia, using smelting technology radically different from that
employed at more Southern sites in the Middle East.

The medieval blue glazed building tiles from some 13th century Selcuk period monuments have been studied.
These monuments are the Beysehir-Kubadabad Small Palace, Sivas Gok Medrese and Tokat Gok Medrese.
Sample collected from these monuments have been analysed for raw materials properties and technological
characteristics.
The study started with the visual analyses and the analyses of the basic physical properties of the tiles. Detailed
analyses of the samples have been done by optical microscopy, scanning electron microscopy with energy
dispersive analyzer and X-ray diffraction analyses.
Visual and microscopic observation showed that the bigger glazed tiles were prepared first, and then cut to
desired shapes to form mosaic tiles.
The tiles are porous, the percent porosity values being 42 to 46. Bulk densities of the tile bodies are in the range
of 1.48-1.60 gr./cm3.
113
Archaeometry '98, Budapest
Combined interpretation of X-ray powder diffraction analyses and microscopic examination of thin sections
reveal the presence of pyroxene, feldspar and quartz as the dominant minerals of the tile bodies.
The analyses show that the glazes have been directly applied without using a slip layer. The glazes have quite
uniform thickness of 150 microns. The composition of the glaze layer is heterogeneous containing minerals rich
in lead or tin, in the glaze matrix.
Heterogeneous nature of the glaze structure and its mineral content have been discussed with reference to X-ray
diffraction analyses and scanning electron microscopic analyses coupled with energy dispersive unit.
Firing temperature of the tiles has been estimated to be around 800 C by considering the mineral composition of
the bodies and their low degree of vitrification observed by the scanning microscope.
189. Some results of study of Cucuteni-Tripolye decoration techniques

Moscow State University Dept. of Archaeology, 23-4-185 Bashilovskaya St., 103287 Moscow, Russia
Present research deals with both relief and painted ornaments of Cucuteni-Tripolye culture in CarpathianDnieper region and changes of decoration techniques in the beginning of middle period of this culture (36503300 BC in uncalibrated dates).
According to the observations wooden sticks or tube bones were used for application of incised decoration and
the implements with a flat terminal - for fluted ornaments. The main tendency in the developing of incised
decoration during early and middle periods of Tripolye was revealed in changes of surface condition: dry
(leather-hard) in early period and more plastic later.
Important innovation in ceramics decoration was the origin of polycolour painted ornaments. The researches on
paintings were provided by laboratory of physical and chemical methods of State Institute of Conservation in
Moscow (N. Podvigina, S. Pisareva, V. Kireeva, A. Levshtein, E. Malachevskaya, N. Travkina). In 1992-93 82
samples from 19 sites of Cucuteni-Tripolye culture were investigated. The technology of paintings looks
reasonably complex. For paintings were used: red pigment of iron oxides and hydroxides, white - kaolin, black compositions on the basis of a iron and manganese. The preparation of dyes was made o the basis of organic
binding - proteins or carbohydrates. They were applied on a surface of vessels after firing. Paintings were
covered with coating of wax or varnish.
As well as changes of ornaments the firing technology was also developed from reduction to oxidize firing.
Such innovations in pottery technology can be interpreted as a reflection of ethnocultural changes.
190. Provenance studies of prehistoric flint from the Gargano mines

Given the peculiarity of the flint mine discovered in the Defensola area , near Vieste (its size and the presence
of artifacts such as working tools, pottery, bone chisels and stone oil lamps) the number of mines in the
Gargano to be analysed has increased in order to try to chemically separate each mine.
The characterization of different mines is the main aim of our study, the ultimate goal being the discovery of the
chemical fingerprint of each type of flint which can be used to recognize the distribution of flint tools in the
Tavoliere Neolithic and Bronze Age sites.
Chemical analysis was performed with a ICP- AES. A total of 13 elements were investigated 13. Factorial
analysis (main component) reduced these elements to 9 (Al, Ba, Ca, Cr, Fe, Mg, K, Li, Ti) for the subsequent
discriminant analysis. This statistical method allowed the separation between the mines and attribution of some
artifacts.
This work represents the first attempt in Italy to distinguish different flint groups by means of chemical
analysis.
114
Archaeometry '98, Budapest
The spatial and the chronological distribution of flint will allow us to build a model about the flint movements
in the area and to find out exactly how far one type of flint travelled. It is clear that the archeological
implications of this research work involve the structure of prehistoric society and its relationship with the
territory.

analysis. For the treatment of analytical data the cluster analysis has been used. The resulting data become a
basis for objective archeological examination of the mineral fillings and further materials and for the

Structural and morphological changes occurring in individual components of ancient human teeth vary with
increasing burial time, hence providing an ideal chance for investigating the interstadial between diagenesis and
fossilization.
Among the main aims of the study was to define the elements which could be considered as indicators of the
interactions between skeletal dental elements and the environment and create the frame for further research.
Another aim was to investigate the diagenetic processes and even the beginning of fossilization of the material
under study.
The analysed material consists of ancient teeth (Sample) of the Middle Helladic Period from the area of Delphi,
dry modern teeth (Control I), teeth extracted recently (Control II), and soil from the excavation area.
The main methods followed were :
.Morphological study under the Optical Microscope and the Scanning Electron Microscope
.EDX Analysis
.ESR Spectroscopy (EPR)
.XRD analysis
The existing results show that:
- Molar ratio Ca/P in the Sample is steady in the dentine and it hasn't been affected by diagenetic processes,
while the corresponding ratio in the outer surface of the root and the root canal, is dramatically increased, an
indication that these areas of the ancient teeth are the areas from where the diagenetic processes start.
- The homogeneity and durability of the structure of cementum and dentine are remarkable, as well as the
resistance of these two components to contamination by soluble minerals, or earthy admixtures.

Fission Track studies for U-microdistribution in different dental components as well as NAA for trace element
concentration have finally enabled better assessment of the extent of diagenesis in human teeth, buried for some
millennia.

Experiments using reconstructed projectile points on modern shafts and employing a modern bow to create a
"best of all worlds" condition are discussed. The experiments entail the use of a ballistics pendulum and high

Large sea transport jars are evidence of commercial traffic in ancient times. Chemical analysis using
Instrumental Neutron Activation Analysis (INAA) is carried out on Basket Handle Jars (BHJs) from the
archaeological site of Mendes in the North-eastern Delta of Egypt. The Chemical analyses of BHJs shows that
they probably derive from Nile alluvium and Western Delta clays. When these data are compared with control
groups from Rhodes, Cyprus and Syro-Palestine, they give negative results. These observations lead to the
rejection of the Hypothesis that BHJs found at Mendes are imports from non-Egyptian Eastern Mediterranean
clay sources. Based on geochemical, historical and archaeological evidence, a new hypothesis may be
formulated for testing: BHJs found at Mendes were manufactured from clay sources located in the vicinity of
present day Alexandria.
195. Preliminary Geoarchaeological Report: Tel Kedwa, Sinai, Egypt
L. A. Pavlish, D. B. Redford
University of Toronto
A preliminary geoarchaeological survey was carried out at the site of Tel Kedwa during the 1997 field season.
This survey had two major objectives:
1.) ascertain the depth of cultural remains on the site; and,
2.) measure relative elevations on the site and in the surrounding environs to calibrate the depth measurements
for the excavation crews.
To accomplish these objectives a grid was set up using the inner corner of the north-west fortification wall.
Measurements show that the transcendental beach to the south of the site is at an elevation of approximately 1
metre above sea level; and, that the transient lake bottom sediments are 10 to 20 cm below that of the beach in
elevation. This lake bottom effectively separates Tel Kedwa from its rather better known neighbour to the south
(two kilometers) Tel el Her or Migdol.
Sixty-three 10 cm diameter auger holes were dug with the objective of ascertaining water table depth, wall
depths, sand foundation platform depths, moat locations and depths in addition to the spatially varying depth of
cultural remains. Thirty-nine of the auger holes were dug along the 300 metre East-West grid line at 0N
providing a reasonable cross-section through the site.
The 2.5 metre contour line describes a roughly rectilinear pattern that is angled at approximately 45 degrees
with respect to the foundation complex representing the unbuilt fort. These results suggest that at least one
earlier architectural manifestation at this site had a very different alignment. The two burn layers present at the
site are consistent with such findings and probably date to the destructions of 587 and 525 BC.

Stone projectile points hafted on modern arrow shafts were shot into the left side of two white-tailed deer
carcasses. The bow used in the experiment was calibrated using both a ballistic pendulum and high-speed
photography. A 66 cm draw on the bow was used for the experimental shots, and it produced a range of
velocities of between 35 meters and 42 meters per second. The bone damage done to the scapulae and the ribs
was recorded. Bone and stone broke with forces of between 300 and 1000 lbs [1.3 x 105 nt and 4.4 x 105 nt].
The bones were cleaned and the damage was photographically catalogued. The observed damage to the whitetailed deer bones may provide a useful frame of reference for the interpretation of similar damage recovered
from an archaeological context and insights into ancient hunting technologies.

Qualitative experiments are carried out on frozen animal femurs in an attempt to establish whether or not bone
fracturing properties vary with the degree of freezing. Fracturing of samples cooled to -196 oC, -40 oC, -25 oC,
0 oC and room temperature (20 oC) is accomplished using a simple two-support beam configuration and a
hammer. All sample specimens are broken by hammer with the exception of the -196 oC degree samples which
are easily broken by hand. Although all bone samples fracture in approximately the same way, the ease of
fracturing increases with decrease in temperature. The -40 oC samples are found to be capable of flaking in a
manner analogous to that of cryptocrystalline materials. In addition, the -40 oC and -25 oC samples exhibit two
fracture types: one which cuts across bone grain structure and one that follows bone grain structure boundaries.
The uniform fracturing qualities are postulated to be the result of bone architecture which remains basically
unaltered by cooling. It is suggested that the freezing of water in the bone is responsible for the increased ease
of bone fracture.
198. The Heating Issue in Ancient Technologies
L. A. Pavlish
Archaeometry Laboratory, Isotrace, University of Toronto, Toronto, Canada
The issue of whether or not prehistoric peoples employed heat treatment of chert and flint as an integral part of
their lithic tool production technology is a matter that has long been debated. While previous
thermoluminescence (TL) investigations of the heating phenomenon concentrate for the most part on finished
artifacts, this study investigates the TL stored in a number of artifacts representing a particular stage in a
manufacturing sequence. While the single analysis approach will not provide the information necessary to
identify purposeful heating, multiple samples (40-100) may provide this information. The examination of Arctic
cores indicates that partial heating was taking place, but does not confirm that it need have been purposeful. The
transition between two blade-flake cultures of Algeria is examined to ascertain whether or not the change in
technology may have been facilitated in part through the agency of purposeful heating. The results suggest that
heating was not a factor in the technology's transition. Finally, the bifacial retouch flakes from a Late
Palaeoindian context are examined and compared with geological source material. Accidental heating does not
explain satisfactorily the fact that the overwhelming majority of the flakes appear to have been heated. One can
conclude that chert heating in this context was purposeful. These results are consistent with the heating model
that is presented and the underlying philosophical principles upon which the model is constructed. The
methodology developed for this work and the implications derived from the resultant data are combined with
other appended archaeological experiments and are discussed. The overall conclusion reached through this
work is that the heating issue will always have to be addressed on a case-by-case basis, and the conceptual tools
employed to make the decisions will be phenomenological in their make-up.

A recirculating laboratory flume was used to study the sorting and relative transport of stone and bone
materials. Fifty-one flume runs were conducted with Froude Numbers between 0.06 and 1.71. Bone and stone
movement was plotted as a function of their rate of movement in centimetres per second (cm/sec) with respect
to their individual mobility numbers (U*).
Low, transition and upper energy flow regimes show a clear separation in the rate of movement of bone and
stone. Settling velocity and drag coefficients are calculated for the material. These results have implications for
understanding distributions of artifactual material on some archaeological sites, and may provide a key to
interpreting the potential for movement on others. Results are applied to field problems.

Glazed ceramics production was one of the most important industries developed during Islamic period in the
Iberian Peninsula. Among the different centres who were making pottery at that time, Saragossa was one of the
most important in the 11th century, in view of the significant group of kilns and quality and quantity of the
objects found in this town: thousands of ceramic objects (jars, large plates, cooking pots, oil lamps, etc.), both
non-glazed and glazed, and also potter's tools, associated with ten kilns.
A complete study of the different types of decorated (monochrome-glazed, two colours-glazed, cuerda seca, tinglazed, etc.) and non-decorated ceramics was carried out, including glazes and bodies, by chemical analysis,
Optical and Scanning Electron Microscopy, in order to know main characteristics and technology of this
ceramic manufacture.
In this case, chemical characterization of coloured glazes by Scanning Electron Microscopy is presented. In
several types of decoration high-lead glazes were used, with different features, chemical composition and
colouring elements. These transparent glazes had some special characteristics in relation to tin-opacified glazes,
produced in these workshops as well.

We have continued our earlier studies on the production and distribution of copper in the south-east European
Chalcolitic by having analysed some 300 metal objects and some 70 copper ore samples from Bulgaria. Trace
element concentrations and lead isotope ratios were determined as in a previous study in Serbia. The combined
data lead to the following major conclusions:
- In contrast to previous assumptions, it seems that the majority of the Chalcolithic copper artefacts are not
made of native copper but of smelted copper
- A considerable fraction (28 out of 192) of the Late Chalcolithic artefacts match ores from Ai Bunar in all
parameters determined. Since among the ore deposits of the Balkans studied so far, the geochemical
characteristics of Ai Bunar are unique, a positive assignment of these artefacts to this ore deposit with
119
Archaeometry '98, Budapest
contemporary mining evidence would appear to be well justified. It is noteworthy that some of the objects
whose metal is assigned to Ai Bunar derive from Plocnik in Serbia.
- Another major group of artefacts resemble those from Serbia that we have previously related to the ore deposit
of Majdanpek. Since most artefacts with such chemical and isotope fingerprints derive from western Bulgaria
this assignment gains support. However, some such objects also have been found along the Lower Danube
suggesting transport of this material towards the Black Sea. Trading of shells in the opposite direction has since
long been proposed on the basis of carbon and oxygen isotope measurements.
- There is still not a single artefact among the suite of some 400 objects from the Balkans attributable to the
Chalcolithic mine of Rudna Glava.

Materials from the archeological place of Alamito, Catamarca, Argentine North West, obtained under A. R.
Gonzlez and V. A. Nuez Regueiro' s direction have been studied. These materials allow to characterize the
most ancient metallurgical culture of the Argentine North West, now considered as a cultural facies named
Condorhuasi-Alamito. It belonged to the formative or earlier period and it was radiocarbonically dated between
200 and 400 AD The task of this work is to determine the obtaining processes, elaboration and transformation
of copper alloys. It was in this place that manufactures, mineral, fluxes, crucibles, hammers, pottery tubes
considered "huairas" or Indian vertical ovens have been found. Quality and quantitative analysis have been
carried out using physical and chemical methods (estereomicroscopy, optical micrography, scanning electronic
microscopy, Edax electronic microwave, X-ray and microhardness determinations). It was determined that all
the cases were copper-lead alloys obtained from a partial fusion of cupriferous ore rich in lead , followed by a
severe plastic deformation of purification and mechanical working by several metallurgical techniques as lateral
hammering, repoussé and stretched applying multiple cold deformation treatments followed by recrystallization
heating. Through this process flat sheets and circular section beams were obtained from quadrangular section
beams.
203. Authenticating Ancient Marble Monuments with Thermoluminescence

Crystal lattice defects on the surface of marble can be produced or annealed by mechanical treatment and
natural irradiation such as sunlight, soil radioactivity and cosmic radiation. The application of
Thermoluminescence (TL) is found particularly useful for a detailed study of such defects providing an
essential step for developing a methodology for authenticating marble objects.
Exposure to sunlight reduces the intensity of the TL peaks to a certain low level. The bleaching rates were
studied on polished and powdered marble samples of different origin and fabrics, and it was found that they
have similar behavior. The reduction of TL peaks decreases with depth on samples exposed to sunlight for
various time intervals. The combined dependence of TL intensity on time of exposure and depth from the
surface was studied, on ancient pieces, continuously exposed to sunlight since antiquity and modern pieces
recently exposed. An equation-model, describing the phenomenon was found. In particular, the model was
tested in three cases of marble objects of known age from 10 to 1000 years old and found to have a very good
approach to dating. This model could be modified to give us information on the exposure time of a marble
monument and its history (burial-exposure to sunlight cycles).
Another potential application of the technique would be to authenticate or date buried objects. Soil radioactivity
and cosmic radiation refill the electron traps that have been emptied by sunlight. A first attempt to date a
sample buried since antiquity, was made. The resulting age is close to the archaeological one. Detailed study to
investigate the potential of this technique for dating buried marble pieces is under way.

**Archaeological Institute of the HAS
The Archaeological Park, as the first open air experimental archaeological museum in Hungary, represents a
unique approach toward reconstructing the past.
Százhalombatta is very rich in archaeological sites and remains of which the most important ones are: a Bonze
Age tell-settlement, an Iron Age earthwork with a huge rampart, an Iron Age tumulus cemetery covering 50
hectars, a Roman military fort and its vicus militaris, etc.
The park is situated in the southernmost part of the Hallstatt tumulus cemetery in an area of 6 hectars. The five
best-preserved tumuli can be found here. One of them, tumulus No. 115 - excavated by Ms. Ágnes Holport - is
unique in Europe because the wooden structure of the burial chamber has survived for 2700 years in its original
form. It was decided to conserve and reconstruct the prehistoric grave in situ. The interior construction and the
exterior presentation of the tumulus reconstruction reflect the original situation.
The tumulus reconstruction is divided by a fence from the so-called "living area", where reconstructions of
houses from the Bronze- and Iron Age are being erected. The work began here in 1996, when two houses, some
hearths and fire places were built and a prehistoric seed planting experiment started. Bronze casting, pottery
making and firing took place together with the use of prehistoric tools.
In 1997, our work enlarged into environmental reconstruction. Our aim is to present the natural and cultural
landscape of the Middle Bronze Age and Iron Age. Our present day climate is very similar to the subatlantic
climate of both prehistoric periods. This means that oak forests advanced at the expense of beech. The replanted
vegetation will thus be representative of the Bronze and Iron Age landscape.
The park is going to be a centre for experimental archaeology and education. The goal is not only to create a
place for tourists but also an area where everything is authentic and constructed on the basis of the
archaeological evidence. This will be a place where we will be able to present prehistoric lifestyles, handicrafts
and agriculture. Archaeologists will be able to carry out various experiments as well as test their ideas and
hypotheses derived from the results of different excavations and empirical observations.
205. Strontium Isotopes and the Bell Beaker Period: Evidence of
Residential Mobility

email tdprice@facstaff.wisc.edu
One of the more important questions in European prehistory deals with the migration of prehistoric groups.
Until recently evidence for such movement was largely based artifacts. A new archaeometric technique,
utilizing strontium isotope ratios in human skeletal material, provides a means for assessing residential changes
directly. Bone, which remodels at a known rate, has a 87Sr/86Sr ratio that reflects the geology of the residence
before death; tooth enamel, which does not remodel, has a ratio reflecting the geology of the place of birth. In
this case study, 66 skeletons from the Bell Beaker period in southern Bavaria were analyzed. Significant
differences between 87Sr/86Sr in bone and tooth enamel indicate that at least 25% of these individuals changed
residence during their lifetime. The overall direction of the migration, according to archaeological finds from
the area, was toward the south-west. A relative surplus of migrating females and two cases of evidence for
migration in children argue for the movement of small groups; exogamy might explain the higher numbers of
immigrating females. This new method has great potential for resolving questions on migration, colonization,
and residence change in the past.
206. Technical Aspects on Greek Mirrors from Southern Italy

Archaeometry '98, Budapest
A number of bronze mirrors are known from Greek colonies in Southern Italy. The present paper deals with
mirrors from the Greek colonial site of Metaponto. Looking at the technical aspects on the manufacturing
technique of these mirrors, certain facts become obvious. First, the mirrors all have a disk which is slightly
convex-concave. Some of them have a decorated 'front' side and a handle, some of them are just plain disks with
or without handles, and lastly some are thick disks with concentrical circles on one side.
From the 5th century B.C. a number of large and elaborate bronze mirrors occur in mainly female burials. All of
them have more or less the shape of a frying pan, with a high upraised rim on the concave, 'back' side of the
disk. Here it is suggested that the often rough finish on the 'back' side originally was covered with a layer of tin
giving an attractive and completely smooth surface. Another type of mirror turned up in burials from the late 4th
to 3rd centuries B.C. These mirrors were called 'pocket' mirrors due to their miniature form, and are small and
plain with no decoration, just around 5 cm in diameter. They are probably cast and thereafter forged and beaten.
Some of these mirrors show a very hard corrosion, which may be traces of tin-plating. On some of them the
reflecting surface is more or less preserved. Different hypotheses about the tinning technique have been
suggested:
1) the tin was poured upon the cold bronze surface in a thin layer to give a more useful reflection, or
2) a possible hot-tin coating, a manufacturing technique consisting of heating the disks, thus melting tin directly
on the surface to be treated.
Tin, with a rapid diffusion into the bronze surface, formed a thin coating of bronze alloy with a high content of
tin and a silvery-white color, and with a very hard surface. Here it is suggested that the concave, 'back' side of
the mirror was poured almost full with hot tin, creating a perfect plane mirror surface of a silvery (white)
appearance, as seen on the vase-paintings. To test this idea small amounts of dirt and dust were mechanically
removed from both surfaces of two of the mirrors and analyzed by Studsvik Material AB in Sweden. The
analyses (BEI - backscatter electron image and SEI - secondary electron image) indicate that tin is present and
give a clear picture of the amount of tin on the concave side.

area of Cherkass region of Ukraine.
Alongside with craft production of potters and smiths with Pastyrske fortified settlement there is the splendid
collection of various ornaments from colour and noble metals, and also finds of jeweller tools. The study of
these materials has allowed for the first time to recreate process of manufacture silver of bracelets with hollow

Pastyrske fortified settlement has Danube sources. The foreman from Pastyrske were remigrations from Danube
region whence a part of the Slavs was compelled move after arrival there Bulgarians in 680 AD. The Slavic
handicraftsmen have brought in Average Dnieper region advanced provincial Byzantine technology. They are
not only copied the Danube prototypes but also creatively developed them.

A successful magnetic measuring in the environment of the city is hardly realizable. There is a strong
electromagnetic noise in a board frequency band. The noise sources are for example the electricity in city
traffic, the spark ignition of the cars, the industrial and civil electrivity consumption and radiocommunication.
Spreaded iron objects are the source of the noise in field domain.

We present some methods of collection of the base data, in the case of different noisiness. Software preprocessing steps developed for these cases can be of help to noise reduction. Stochastic (for example Wiener
type) filter as well as the deterministic one are used with good results for reducing the noise in field domain.
The illustration is based on real survey data.

Microfossils, the mineralised remains of various groups of single-celled marine and non-marine plants and
animals, are a common and distinctive component of archaeological ceramics. The frequent occurrence of these
minute structures in pottery of different periods and from varying geographical locations has often been noted,
but only limited attention has been paid to their potential as a means of characterising and grouping ceramics.
After a brief review of previous work, this paper discusses the results of a project which has examined the
potentials and limitations of the application of all groups of microfossils to archaeological ceramics. It details
the way in which the highly specialised discipline of micropalaeontology might be applied to a variety of
archaeological problems.
Case studies from the Southern Aegean are used to demonstrate how such techniques may be used to either
confirm or question ceramic groups made by other methods, to investigate the mixing of clays, and how
micropalaeontology may be useful in provenance studies. Its sourcing capability is considered on two levels:
that of suggesting specific clay sources exploited near to known production centres and in distinguishing
ceramic exchange over long distances.
The limitations of these techniques revolve around the difficulty of studying microfossils in thin sections, their
ability to survive in a variety of firing conditions and the occurrence of similar aged sediments over large areas,
such as on Crete. Micropalaeontological techniques and especially nannopalaeontology are shown to have
potential in answering closely formulated archaeological questions, when combined with other techniques of
ceramic analysis.
211. Chemical investigations of organic materials preserved in Neolithic
ceramic vessels from lake-dwellings (Chalain lake, Jura, France)

At the lake-dwellings of Chalain the majority of the ceramic vessels are characterised by the presence of
extensive charred surface residues which provide clear evidence for their functional role. These carbonised
residues and the organic materials absorbed in the porous fabrics have been chemically investigated in order to
123
Archaeometry '98, Budapest
identify the commodities processed in the vessels (Horgen and Clairvaux cultures, respectively 3200-3100 BC
and 3040-2950 BC, solar years).
Gas chromatography (GC) and GC/mass spectrometry (GC/MS) analyses of the solvent soluble fraction
revealed the presence of high quantities of lipid. The pattern of the different homologous compounds (free fatty
acids, mono-, di- and triacylglycerols) is characteristic of the presence of animal fats in all the vessels
investigated. Detailed assignments of odd carbon numbered fatty acids, close study of triacylglycerol
distributions and the results of δ13C measurements of the major fatty acids from the neutral fraction (GCcombustion-isotope ratio-mass spectrometry analyses) provided evidence for the use of ruminant fats. One
vessel, characterised by a more complex GC profile, is thought to have contained beeswax as it has already been
reported in association with other archaeological vessels (Charters et al., 1995).
Protein markers such as indole, pyrrole and diketopiperazine derivatives have been identified by pyrolysis-GC
(Py-GC) and Py-GC/MS, highlighting the preservation of proteinaceous materials in the vessels.
Comparison of these data with the information recorded from faunal remains (Arbogast, 1997), are of great
importance for the understanding of procurement, management and wide use of animal fats during Final
Neolithic at the Chalain lake-dwellings.

212. A Late Neolithic Production Site For Axe Flakes Near Kottenheim, Kr.
Mayen-Koblenz, Germany
K. Rehn
Oppelner Strasse 17, 53119 Bonn Germany
Volcanic rock such as pumice, lava and basalt are predominant for the area of the Middle-Rhine and the eastern
part of the Eifel. They are still part of mining- industry of present Germany. The Prehistoric people, however,
used this raw material, too.
In between the villages of Mayen and Kottenheim, is the torrent of lava of the „Bellberg” with the so called
„Winnfeld”. Four ground- plans of prehistoric huts, averaging 3x3.5 meters in size, where excavated here by the
Provincial Museum of Bonn in 1916. Two of Which overlapped each other, so that they obviously did not exist
at the same time. According to the ceramic finds, all four huts can be dated to the late- Neolithic.
The rock made artifacts from the site deserve special attention. Approximately 80 pieces allow the assumption
that axe flakes were produced on a larger scale here. Rough- outs, blanks, flakes and waste material reflect all
stages of manufacture from the raw material to the finished product.
Hammerstones(quartz) served as universal tools. They were being used to carve rough-outs. By secondary
flaking, blanks with distinct edge and neck portions where then produced. The hammerstones were also used to
give the blanks a regular scarred surface by picking. A final shaping followed by grinding and polishing. For
the letter special sandstones (Bundsandstein) were being used, which had to be imported to this place.
Mostly the axe flakes were made of quartzite, which is available in the area. There are no indications of quarry
activities. In any case rubble was selected.
213. Prehistoric tin metallurgy in the Bohemian/Saxon Erzgebirge

*Deutsches Bergbau-Museum Bochum,
Saechsisches Landesamt für Archaeologie, Dresden
The search for tin resources is a long-standing issue in Bronze Age archaeometallurgy, but only during the
recent past, increasing scientific evidence appeared for early tin metallurgy. The Erzgebirge is among the major
potential tin sources of antiquity in Europe, with evidence for tin mining well into the Middle Ages, and a
124
Archaeometry '98, Budapest
suspiciously rich Bronze Age culture. A recent survey program in this area produced a couple of finds related to
tin metallurgy. These range from slagged furnace material to crucible fragments with repeated layers of tindominated dross. The furnace fragment indicates smelting of mixed copper-tin ores, using predominantly tin
mineral, forming a fayalitic slag. The crucibles contain much more tin oxide than copper oxides, and residual
intermetallic phases from the tin-rich end of the copper-tin system. In one case, the melting vessel was used at
least four times for similar successive operations. The finds will be presented in detail and the analytical results
(optical microscopy, microprobe analysis, chemical analysis) interpreted in view of their archaeological
background and early tin metallurgy in general. The discussion will include comparative material from a Middle
Bronze Age site in the Alps. Due to the survey character of the archaeological program, the finds studied so far
are from different sites. Therefore, the interpretation can be done only on a preliminary level. The clear
evidence for tin metallurgy in the Erzgebirge region and in particular the identification of tin smelting, however,
appears as a highly promising incentive for further field work here.
214. The development of analytical cupellation in the Middle Ages
Th. Rehren*, K. Eckstein**
*Deutsches Bergbau-Museum Bochum,
**TU Bergakademie Freiberg
From the Renaissance onwards, we have plenty of physical and documentary evidence for the use of
cupellation as an analytical tool for noble metal determinations. The roots of this technique are evidently the full
scale cupellation of argentiferous lead, used from the Bronze Age onwards. The origins of cupellation as an
analytical tool, that is for the treatment of a sample representing the total, are still unclear. This development
most probably took place during the Middle Ages. The presentation will include microscopic and analytical data
from two extremely well preserved Central European finds, dated to the 11th and 14th century AD, which
illustrate the change from the full scale procedure to the small size, analytical process. This reduction in size
goes along with the development of the bone-ash cupel as a free standing vessel, as opposed to the traditional
cupellation hearth build into the ground. Then, these data will be put into relation to better known early Modern
Period material from Austria, allowing to establish different recipes for the making of cupels. Additionally,
relevant written sources will be cited to illustrate the background of this development that ultimately leads to the
establishing of analytical chemistry as a merger of metallurgical fire assay and alchemical experimental
practice.
215. Reconstructing Human Diet in the Neolithic of North-West Europe
using Bone Stable Isotopes
Mike Richards, R.E.M. Hedges
Research Laboratory for Archaeology and the History of Art, 6 Keble Road, Oxford, OX1 3QJ, U.K.
The Neolithic of North-West Europe is a period of great social upheaval. Along with new innovations like
pottery and monumental architecture, there is the first use of domesticated plants and animals. However, the
artifactual evidence for subsistence during this important period of prehistory is inconclusive, and there are
questions about how rapidly the change in diet occurred, and even what form Neolithic subsistence took. Bone
stable isotope analysis can provide us with new information about subsistence that may help to fill in the gaps
left by the archaeology. We will report on a large scale study of human bone stable isotopes from a number of
Neolithic sites, mostly in Britain, which shed new light on the nature of Neolithic subsistence, and by
implication, Neolithic society.

Holocene Period

This paper forms part of a preliminary study focused on the determination of feeding habits on two human
samples and four different mammal species recollected during a field trip on the valley of Chalco on the state of
125
Archaeometry '98, Budapest
Oaxaca, Mexico. Another objective was to find its relation with the process of fossilization in order to
complement the studies made in sight to establish a tentative chronology of those found on archeological and
paleontological recollections. This work forms part of an agreement made with the Musée de L'Homme from
Paris, France.
The first human sample (SFI001-I) and those animal (SFI008-III) were found in a sotomonte on the Mixteca
sierra, Oaxaca, close to a village with the name of San Felipe Ixtapa. This region presents three levels of
settlement clearly established, even though some are altered by rockslides. The levels are, from the most recent
to the oldest, from the Colonial period, Prehispanic (postclasic and preclasic) and from the Pleistocene Holocene transition (confirmed by lithic material).
The SFI001-I sample belongs to a female subject of about 45 years old found on a burial made with basaltic
rock flagstones. The mammal remains belonged to a bison, coyote and deer.
The second human sample (LCH045-I) belongs to a male of about 22 years old found on the surroundings from
Chalco ex-lake, Mexico state. He was found near the surface and is associated to some sherds.
The studies were made using a thermic absorption dispositive PEKIN ELDER MOD 370 with the right kind of
lamp used on each case in order to make an interpolation of curves for the each metal.
The results on the content of Ca, Ba, Pb, Cd, Zn and Mg on every sample does not show any insight about their
feeding habits; however, since there is no relation in the way the samples were found, it cannot be stabilised
one. A palynological study is required in order to shed more light about it. Nevertheless the studies gave some
interesting lectures, especially on sample SFI001-I as it is the contamination by volcanism which can modify
the studies about migration routes.
217. Large Scale Paleoecology Using Opal Phytolith Analysis in Small Scale
Sites
Irwin Rovner
North Carolina State University Raleigh, NC, 27695-8107,USA, (IRV@worldnet.att.net)
Recent developments in plant opal phytolith analysis provide many new avenues of archaeobotanic and
paleoecological data in a broad variety of contexts. Several recent phytoliths-studies in small Late Pleistocene
and Holocene sites generated patterns of data that cast the potential application of phytolith analysis in a new
light. Phytolith data is not merely a redundant or impoverished substitute for pollen data. The sites studied
were small scale causing very little impact on the natural ecology. Yet, small scale microenvironmental change
caused by human activity invited phytolith evidence for large scale climate change. Such evidence not readily
available in the pollen record in terms of identified flora, level of floristic scale and many rather more subtle
ethnobotanic activities exposing aspects of the local environment and human activity within it. This occurred in
a forest zone where pollen data is expected to be strong and phytolith data, normally considered applicable to
paleo environments dominated by grasses, is thought to be weak. Phytolith data contributes significant data that
is independent, and often unique. Results both enhance and are enhanced by parallel studies of pollen or,
indeed, any method of paleoenvironmental analysis and interpretation.

Modern organic archaeometry, at least modern archaeometrical tar analysis, literally began with the
investigation of residues found on ships [1, 2]. Pine tar origin was confirmed for samples found on or in ships
from antiquity [3, 4], the Middle Ages [1,5], and the 18th century [6]. Research on Norwegian tars from ships is
quite rare [5,7]. However, there are some recent investigations on tar production and application in Norway
[8].Cultural context. Organic material from two mediaeval Norwegian ships, one mediaeval and one Viking
age, was analysed. These are the Sjoevollen ship (1210 AD, [9]) and the Gokstad ship (895 AD, [10]),now held
at the Viking Ship Museum in Oslo. Research objectives. Main objective is the identification or the
126
Archaeometry '98, Budapest
characterization of the organic material. Additionally, a comparison of these samples and the results reported by
other groups is performed. Analytical techniques. Samples were analyzed using gas chromatography and
combined gas chromatography / mass spectrometry. Results significance. Both historical samples are pine tars,
which is confirmed by the similarity of their compound pattern to that of authentic pine tar. A comparison of
results of the analyses of recently kiln-produced pine tars with results of other investigations shows significant
differences for most of the tars analyzed so far including the Sjoevollen sample on the one hand, and the
Gokstad tar on the other. These differences are discussed in more detail referring to the compound patterns. It is
argued that the so-called Stockholm tar is not restricted to Stockholm respectively Sweden. This kind of tar
probably was manufactured all over Sweden, Norway, and Finland as well. As for the Gokstad sample, the first
chemical analysis of a Norwegian Viking age tar is presented.

219. On Casting Mould of the Northern-East Balkan Eneolithic
Natalja Ryndina
Archaeological Department, Moscow State University,119899 Moscow,Russia
The most impressive Eneolithic metal objects come from the sites within the area of Gumelnitsa, Varna, VincaPloenic, Cucuteni-Tripolje and Tiszapolgar-Bodrogkeresztur cultures in SE Europe dated to the IV millennium
BC. Now there are over 4000 objects in the collection and among them nearly 1500 are large tools of striking
function (axe-adzes, axe-hammers, adze-chisels etc.). In spite of huge concentrations of large cast items in the
Balkan-Carpathian region, Eneolithic casting moulds are still practically unknown. Discussion on what these
moulds might have been made of and their construction is still among the matters of top interest for
archaeologists. 242 samples obtained from Bulgarian museum collections have been investigated in the
metallographical laboratory of the Archaeological Department of Moscow State University. They were
extracted from metal objects found on the sites of Gumelnitsa and Varna cultures located in the Northern
Balkans. Thorough microstuctural and micro X-ray spectral analysis revealed the fact that casting moulds would
be often made of graphite. Graphite dissolves in the outer layers of copper castings enriched with oxygen. As
carbon diffuses into copper, copper-oxygen reaction starts, which, because of the slow kinetics of the process,
occurs only on the surface between the casting mould and metal. As a result a deoxidized zone is being formed.
Similar zones were observed in microstructures of a variety of objects: axe-hammers of Vidra, Codor, CokaVarna types, adze-chisels of Gumelnitsa and Salkuta types. Graphite stands temperatures up to 2500[C in the

Tafí valley is an intermontane valley located at Tucumán in the Northwest Argentina that typifies Holocene
environmental evolution.
From the archaeological point of view, it was determined that the most important occupation was during
Formative period (300 BC to 800 AC). They were identified many different kind of prehispanic constructions,
most of them destined to agricultural works (they are some of the most earlier structures purpose-built to this
works in Northwest Argentina). after this period the valley was practical abandoned by unknown reasons
according to previous studies. Towards the moment some typical features were identified but environmental
processes or sites evolution were never studied.
On this paper we used environmental data from nearest areas together with archaeological digs, photo
interpretation and radiocarbon data from agricultural structures presents on the valley.
Our results are very significant, we determined an edaphic sequence composed by three cycles. One of them
(the central one) was intensively cultivated and it present some outstanding features of soil degradation
(absence of phosphorous, present on the other edaphic cycles) and erosion (absence of A horizons) probably a
product of agricultural practice but influenced by a regional environmental aridisation process.
This is an important approach to the understanding of the poblacional dynamic of the valley that according to
previous studies was practically abandoned after this period.
221. Qualitative and quantitative analysis of silver coins struck under the

**Hungarian National Museum, Budapest
Energy - Dispersive X - Ray Fluorescence technique was applied for analysis of silver coins to determine the
elemental composition in a fast and non-destructive way. The non-destructivity of the analysis is very important
when it is not possible to destroy the structure of the ancient, precious coins.
In this present work we have developed a quantitative method for samples with different size and geometry.
This method was employed for coins with two components, Ag and Cu, where the content of the trace elements
is under 0,1 %. All the coins and standards were exposed to an annular 1-125 source: the X - ray radiation was
collected by a Si(Li) detector with associated electronics and a multichannel analyser which was coupled to a
computer.
The usefulness of the method has been confirmed by analysing certificate silver alloys. The agreement between
the measured and true values is good. The precision that is indicated by the relative standard deviation (RSD %)
is under +- 4 %.
Silver coins were analysed from the collection of the Hungarian National Museum and the Hungarian National
Bank, struck in Hungary during the reign of Mathias (1458-1490) and Nicholas Újlaky, king of Bosnia (14641476).
Before the far reaching monetary reform of Mathias in 1467, the fineness and the weight of the silver coins
fluctuated year by year and the written sources are very sporadic. After 1467 the standard of coinage officially
remained the same, but the analysis indicates that it is not sure. We are in the same situation with the denars of
Újlaky, who struck his coins as the king of Bosnia, the same type as Mathias did.
In our poster we present the concentration values of the main components and a list of trace elements,
comparing the results of the EDXRF analysis with the data of contemporary written sources.

The geophysical mapping of the Neolithic Settlement of Kantou-Koufovounos, in Cyprus, was conducted as
part of the continuing archaeological research program in the specific area. The goals of the project included the
mapping of the shallow depth architectural remains of the site in order to assess the limits of the settlement and
plan the future excavations of the site. Magnetic surveying was successfully applied, together with soil
resistivity prospecting. Both techniques resulted to a number of features that have been correlated to the
existence of architectural features. The electromagnetic survey (EM38) encountered various problems related to
the balancing of the instrument due to the extreme high temperatures, the high resistivity of the shallow bedrock
and the lack of contact with the surface due to the dense vegetation islets and bedrock outcrops that were
scattered in the area. The magnetic susceptibility maps, covering an area with existing architectural relics,
resulted to a detail mapping of their inner details, in close correlation to the other techniques.
Subsequent excavations in the following year revealed a number of architectural features which were located by
the use of geophysical prospection techniques. The geophysical maps indicate that the site extends in the north
and east directions with no evidence of a surrounding defensive structure. Further geophysical work is planned
to map the relics on the slope of the hill. The final product will consist of the superposition of the excavated
regions on the geophysical maps to provide a tool for the management and preservation of the site and its
environmental settings.

The island of Amorgos has become the target of micro-scale geophysical prospecting and macro-scale satellite
remote sensing investigations. The goal of the project was the formulation of a general strategy for applying a
wide spectrum of remote sensing techniques and integrating the corresponding results to the general framework
of archaeological research.
The geophysical survey was conducted in two remote areas, accessible only by foot, a coastal Roman site and a
hilly site dated from the Early Cycladic period. Magnetic and soil resistance surveys were carried out at the
particular sites for mapping the subsurface relics. A systematic surface survey was applied on the same grids.
The correlation of the geophysical maps and the surface sherd concentration has drawn specific results about the
boundaries of the E.C. site. Geophysical surveying was also able to detect architectural remains of the Roman
site, most of which are either covered completely by alluvium deposits, or are submerged within the sea due to
the past seismic activity.
Aerial photographs were used for creating the aerial mosaic of the wider region. The geophysical grids were
registered to the aerial images and both layers were superimposed on the DEM of the region. Two Landsat TM
images were combined to produce the satellite mosaic of the whole island. Processing of the different bands
was used for creating a number of thematic maps. The satellite image was also superimposed on the DEM of
the whole island and other layers such as the digitized geological maps were added for producing a GIS.
Digitization processes and Sub-centimetre accuracy Global Positioning Systems were used specifically for the
registration of the known archaeological sites and Ground Truthing procedures of the environmental and
cultural variables. Supervised classification techniques have been used for modelling the settlement patterns of
the island.

The island of Amorgos has been used as a pilot study for the application of large and small scale investigations
of the archaeological sites of Greece, proposing a model of archaeological site assessment and the creation of an
electronic archaeological and monument record through the use of Geographic Information Systems.

For the last 4 years, a coalition of European researchers is studying the archaeological site of Itanos (E. Crete,
Greece) from various archaeological, environmental and geophysical aspects. The program, supervised by the
Institute of Mediterranean Studies and the French School of Archaeological Sciences, has integrated a number
of techniques for accessing the archaeological and environmental parameters of the wider archaeological region.
The purpose of the geophysical survey was to map the buried archaeological relics, including remnants of
buildings, streets and walls in the extended area of the archaeological site. Furthermore, the site has been used
for testing a number of high resolution conventional and non-conventional techniques.
Seismic refraction and reflection techniques were used for detecting the ancient port of the site and mapping the
bedrock of the area which is covered by alluvium deposits. The ancient port was also the target of GPR and
electrical tomography prospecting, which encountered serious problems due to the shallow depth of the water
table.
The results of the geophysical, topography and archaeological survey are superimposed on the aerial mosaic of
the region. The general assessment of archaeological sites is proceeded through the use of Landsat and SPOT
imagery (the last of which has been re-sampled to 5m accuracy, through pixel-mixing techniques). Subcentimeter accuracy Global Positioning Systems were used specifically for the above registration of
archaeological, environmental and geophysical features.
The archaeological site of Itanos has been developed to an actual remote sensing lab, where different
approaches are applied in order to maximize the information context of the site.

In a project funded by the Austrian research fund (FWF), on identification and characterization of local pottery
production sites in Southern Italy, various pottery products from different cities of Magna Grecia were studied
using the combination of thin section and heavy mineral analyses and comparing them with their local clay raw
materials.
Samples from the following sites were included in this study: Puteoli, Surrentum, Poseidonia, Hipponion, Velia,
Rhegion, Locri, Caulonia, Croton, Sibari, Messina, Naxos. This project was performed in addition to an
archeometric study of the archaic pottery of Velia.
The information from this study are used as an aid to improve the identification of the provenance of possible
import ceramics at Velia and especially to get a better understanding of the origin of the various transport
amphorae found at Velia.
131
Archaeometry '98, Budapest
For this project mainly common ware and bricks, where a domestic production could be assumed, have been
used. Subordinate samples of amphorae and fine wares were also available. Potential clay deposits and rawmaterials were collected near the archaeological sites and studied. Additionally some quality tests with selected
raw-material samples were performed (various clay preparations, burning at variable burning temperatures,
etc.).
The results of this study show that a combination of thin section and heavy mineral analyses enables
identification and characterisation of local pottery production in most of the studied sites. In many cases the
clay raw materials used for the pottery could be directly linked with the collected samples. Results from
significant examples and analyses are presented.
Typically in almost all studies cases more one local raw material was used simultaneously. This should be kept
in mind especially during interpretations of chemical analyses (especially for provenance analyses of common
ware).
Furthermore, it is necessary to do a direct study from and around the archaeological sites. Geological literature
is often only of very limited value in characterising pottery raw materials. Proper mineralogical information in
literature on potential clay deposits and their natural impurities are very scarce and should always be checked by
reference samples. Using volcanic material as an argument for provenance information, especially if based on
published geological information only, sometimes could be very misleading.
226. Diagenetic processes in fossil wood ash deposits in Kebara and
Hayonim Caves (Israel)

Postfach 103980 69029 Heidelberg Germany
A series of ash-derived sediments of Mousterian age in Kebara and Hayonim caves (Israel) was studied for their
mineral composition and postburial alteration processes (diagenesis). The mineral composition of experimental
and fossil ashes was determined by means of Fourier Transform Infrared Spectroscopy (FTIR), X-ray
diffraction techniques, Scanning Electron Microscopy linked with an Energy Dispersive X-ray Analytical
System (SEM-EDAX), Electron Probe Microanalytical techniques, and by Optical Microscopy. Modern plant
ashes as well as extraordinarily well preserved fossil ash consist predominantly of calcite. In addition, fresh ash
and very well preserved fossil ash contain about 3 vol. % siliceous aggregates which are by far less soluble than
the ash calcite. In the course of diagnoses ash may undergo a continuous change in composition. By percolating
phosphate bearing solutions the initially dominant calcite component may be dissolved or replaced by a
sequence of secondary phosphate minerals (appetite, montgomeryite, taranakite, crandallite, leucophosphate).
Consequently, during diagenesis the ash becomes enriched in the more stable siliceous aggregates and
undergoes a reduction in volume of 20 to 50 times.
The archaeological implications of these investigations are:
a/ Areas with well preserved sediment context are reflected by calcitic or apatitic ash deposits.
b/ The presence of siliceous aggregates in these cave sediments in indicative of the original presence of ash
deposits in those areas in which ash lenses are no more recognizable.
c/ The volume reduction caused by diagenetic alterations in ash deposits may result in vertical displacement of
the enclosed lithics.
d/ In both caves the ash diagenesis is connected to increases in potassium content of the sediments. Due to
alterations in the content of radioactive K(40) the representativity of environmental gamma-dosimetry is not
ascertained. Consequently, TL-dating of burnt lithics enclosed in diagenetically altered sediments is problematic
and the lithics should be sampled from unaltered calcitic or slightly altered calcitic to apatitic hearths.

Archaeometry '98, Budapest
With geological studies of Neolithic stone tools we can obtain many pieces of archaeological information such
as sites of Neolithic workshops and trade-routes. Parallel to the studies of the tools it is necessary to investigate
the potential raw materials, too. Unfortunately, the provenance of some rock types can be determined only with
rough estimations, sometimes it is not possible at all. Such rock types are for example the sedimentary rocks. It
is a consequence of the relative small variability and great distribution of these rocks. Concerning tools made of
metamorphic and igneous rocks the determination of the provenance can be more exact.
Investigation of tools and potential raw materials begins with studying the macroscopic features. From these
results we can not draw far-reaching conclusions, because the surface of the tools may be altered considerably
by the persistent burial near the surface. More details can be obtained by studying thin sections of the tools. If
the mineral composition and textural features of the supposed raw material are very similar to those of the stone
tool, it is probable that they are of the same origin.
Decisive evidence can be given by the analysis of microelements and mineral chemistry. We use the following
analytical methods: NAA, microanalysis, X-ray diffraction. Should the data obtained from the analysis of the
tool and the supposed raw material correspond even at this level, the provenance of the stone tool is in all
probability found.
Using the above outlined method we investigate 18 stone tools of the Zengővárkony findings owned by the
Janus Pannonius Museum, Pécs.

**Aquincum Museum, Szentendrei ut 139, 1031 Budapest, Hungary
Roman pottery production in Aquincum and in other parts of modern Budapest is well known from excavations
of various kiln sites. Selected finds from those were used for a chemical study to get some answers on questions
of Roman pottery and lamp production in Pannonia. How many distinguishable raw materials were used in
Aquincum to produce coarse wares, fine wares and lamps? Are moulds, also those with stamps of names known
from other sites, all made locally? From finds of moulds it is evident that Firmalampen, the most common type
of Roman lamps in Pannonia and in the northern Roman provinces after the middle of the 1st century AD,
were made in Aquincum but for the imported Firmalampen it is not known how many and which lamp-making
centres play a significant role and, also, if lamp-makers in Aquincum produced for large scale export. Analyses
of 80 samples from Aquincum by WD-XRF are compared to analysed pottery and lamps from Intercisa,
Poetovio and Carnuntum and used to demonstrate the possibilities and limits of chemical analysis for
provenancing.

An increasing number of instrumental analytical techniques has been applied for studying the material
composition of objects of art and archaeology. Among these techniques X-ray fluorescence analysis (XRF)
using x- or g-ray for the excitation have gained growing interest. A major advantage of such systems is their
non-destructive applicability, which means that no sample material has to be gained from the object for the
examination. However, a big disadvantage is that such systems described in the literature have used a x- or gray beam of several millimetres or even centimetres in diameter and the characteristic radiation of the elements
with low atomic numbers (Na - S) is absorbed due to the fact that these instruments are air-path systems.
A new spectrometer was designed for pixel-by-pixel analysis along lines or within selected areas. The technical
details of this instrument are already described in the literature [1-3]. It consists of a spectroscopic X-ray tube of
max. 60 kV/2.8 kW and an energy dispersive Si/Li-detector and enables both the analysis of points selected
133
Archaeometry '98, Budapest
prior to analysis as well as the imaging of the elemental distributions along lines or within selected areas.
Several collimators and a shutter unit define an effective beam diameter of 1 mm and below. X-ray tube,
detector and laser pointing device for selecting the points of analysis are mounted on a platform, which can be
moved by 3 DC-motors in horizontal and vertical direction in front of the object as well as towards or away
from the artefact. Optically encoded glass scales with a resolution of 10 mm are employed for the determination
of the exact position of the tube/detector assembly.
Additionally, a He-flush system was developed in order to solve the problem of absorption of the characteristic
X-ray radiation of the elements Na - S. This project was carried out within the frame of the COST G1-Action
"Application of Ion Beam Analysis in Art and Archaeology" supported by the European Union. Examples for
the identification of pigments such as blue ultramarine (Na, Al, Si, S, Ca, Fe) or cobalt blue (Co-glass) as well
as objects made of glass and ceramics are presented.

230. IMMACO: Improvement of Means of Measurements on
Archaeological Copper Alloys for Characterization and Conservation
within a European Research Project
Manfred Schreiner
Institute of Analytical Chemistry, Vienna University of Technology, Getreidemarkt 9, A-1060 Vienna/Austria
During the last decades an increasing number of instrumental analytical methods has been applied for studying
metallic archaeological artefacts. Within these techniques spectroscopic methods have provided a great number
of elemental analyses of such artefacts and have enabled a statistical evaluation of the data as well as a
correlation of the chemical composition of the objects with the raw materials used for their manufacturing.
However, due to the lack of reference materials, especially with regard to the elemental composition of
archaeological copper alloys, a comparison of the results published in the literature and any historical
interpretation is rather difficult. Therefore, an international co-operation has been built up in order to make reliable tools for scientists working in the field of archaeology and conservation. These tools are:
- Certified Reference Materials (CRMs) for the calibration of bulk elemental analysis of ternary and quaternary
copper alloys,
- an analytical practice guide for the use of energy dispersive x-ray fluorescence analysis for the study of the
bulk composition of archaeological metallic artefacts,
- an analytical practice guide for the study of the surface of artefacts in cases where the investigation should be
non-destructive,
- assessment of the limits of the correlation between outer (corroded surface) and inner (bulk) composition,
- improvement and optimization of the electrochemical methods available for monitoring the corrosion
behavior.

Porolissensium in Dacia
Florin Scurtu
Geological Survey Romania, Str. Sibiu Nr. 10, bl OS1, ap. 138, 77317 Bucharest 66 Romania
The old Porolissium was a piece of the long chain of forts built up by the Romans along the north limes of the
Roman empire.
The ruins of the fort show that it was about 300 m long and about 200 m wide. About 5000-7000 soldiers stayed
permanently in the fort. At a small distance of the fort walls a Roman amphitheatre was found.
Around the military fort a civil settlement of about 20,000 inhabitants (Forni, 1976) was built up during the
time. Few (5-6) buildings were found by the archaeological works east of the fort, but no trace of buildings is
visible in the area geophysically studied by us, south of the fort.
The walls of the aedificia are built essentially in blocks of andesite (magnetic susceptibility of about 2000
μuCGS). The electrical resistivity of the sediments of Quaternary age is of about 20 ohmmeters, much less than
that of underlying sandstones and conglomerats.
In a first step a magnetic survey in a very dense grid was used in order to check the possibilities of the method.
The results obtained in a small area of 20 m by about 90 m showed that the method works very well, walls and
rooms being clearly represented in the image (see the figure), after all the geophysical corrections (diurnal
variation, geographical variation and geological variation) and the needed mathematical filtering were applied.
In a second step, a larger area, of about 2.2 Ha, was studied using the same methodology. The results are
spectacular: a Roman road of about 7 m wide and 150 m long (including its change of direction at 90o), a lot of
buildings between 6 m by 6 m and 40 m by 40 m in dimensions, streets, fountains and platforms of monuments
appear very clearly on the old town left by the Romans 17 centuries ago. The resistivity measurements (most of
them vertical electrical soundings) show that the people living there could have the necessary groundwater
under their feet.

**Israel Antiquities Authority, P.O. Box 586, Jerusalem 91004, Israel.
Recent excavations at Ashkelon - Afridar Areas E, G and H have revealed numerous remains of metallurgical
activity. The occupational remains uncovered in these excavation areas have been dated by the excavators to a
very early stage of the Early Bronze period (EB Ia).
In order to reconstruct the ancient metallurgical technology at the site, to define the provenance of the copper
and to assess the skill of the ancient craftsmen, the chemical, isotopic and mineralogical composition, as well as
the metallographic structure of slags, prills and metal artifacts was determined and analyzed. ICP-AES, ICPMS, XRD and SEM-EDS were used for these analyses.
From our present research, it is clear that there are no significant changes both in the composition of slags and
production technology of metal between the Chalcolithic and the EB I periods. The chemical and mineralogical
composition and isotope ratios of slags and pure copper objects point to Feinan region as source of the ore. The
raw (black) copper has been delivered from Feinan region. Objects made of pure copper were produced at the
135
Archaeometry '98, Budapest
site. The technology at EB I Ashkelon - Afridar included use of open casting, the possible use of the "lost-wax"
casting technique, hot and cold forging and annealing. The small dagger/amulet made of arsenical copper and
two plates (convex and tube) made of leaded copper were probably imported to the site.

It has been shown that European white glass trade beads in north-eastern North America start the 17th century
with beads opacified by tin, finish the 17th century with antimony opacification and end the 18th century with
arsenic opacified beads. In an attempt to define more closely the transition from tin-rich to antimony-rich white
beads, we analyzed an additional 129 white glass beads from a number of archaeological sites in western New
York State that covered the 17th century. Chemical analysis shows that the arrival of antimony-white glass
trade beads occurs at about 1650 C.E.
234. The calculation of the iron production based on the chemical balance
between ore and slags.
Serneels, Vincent
Centre d'Analyse Minérale, Earth Sciences Department, University of Lausanne, Switzerland.
The early medieval bloomery of Boécourt - Les Boulies (Jura / Switzerland) has been excavated in 1989
(Eschenlohr and Serneels 1991). The mineralogical and chemical study of the metallurgical wastes leads to the
development of a method for the calculation of the iron production based on bulk chemical analyses (mainly
XRF). In this case very accurate data were available, due to the good preservation of the archaeological remains
and the particular chemical composition of the ore.
This method has been applied, with more or less success, to several other examples based on archaeological,
experimental and ethnographical data. Results, sources of error and related problems are discussed. In areas
where ancient slag-heaps are preserved, this method is a very useful tool to quantify the iron production and
understand the importance of the iron industry.

In the last decade, the analysis of archaeological obsidian using wavelength and energy-dispersive X-ray
fluorescence spectrometry has become increasingly common. As in most cases where a relatively new
application is embraced by archaeologists and supplied by the physical sciences, the understanding between the
two groups is not necessarily very fluid. An emphasis by the physical scientists on the precision of the
measurement without an understanding of the silicic melt reactions that produced the glass is in opposition to
the ignorance many archaeologists possess in understanding either instrumental precision or accuracy in
assigning an artifact to source. This lack of mutual understanding presents a number of problems for both
136

archaeometrists and archaeologists, and can undermine the use of this important analytical method in the service
of interpreting issues of exchange, group interaction and raw material procurement. Using data from the
Berkeley XRF lab and obsidian from the American Southwest, these issues will be explored, and solutions
proposed in the hope of bridging the gap between the archaeometrist and archaeologist.
236. The experimental study of the tools on the fragments of the pottery

The fragments of the vessels with the traces of the re-using were determined in course of investigation of the
pottery of the settlements Eneolithic-Early Bronze Age of the Middle Trans-Urals. The majority of such
instruments had the working traces on the edges in form of the linear features, polish, rounding. Prof. G.F.
Korobkova investigated the similar scrapers for a wood and a hide processing in collections of Eneolithic sites
of the Middle Asia and Caucasus. The series of the experiments was made for determination of the functions of
the tools from the Urals monuments. The use-wear analysis of the experimental and the archaeological
implements was made through the stereo microscope. The magnification up to 100(x) was used. The fragments
of the pottery were not effective for the scraping dry or fresh wood. The good result was attained for the
production of the grooves and cavities after the scorching of the wood. Probably, the main part of the
archaeological tools was connected with the hide-processing. The best results were achieved for the scraping a
hide dried a little (the worked-material was placed on a soft ground or a thigh) and for the hair-removing. The
fragments of the pottery were used as the grinder for the metal tools. Besides, the ceramics implements are
effective for scaling of a fish. Probably, the using of the tools on the fragments of the pottery saved time and
labour for the raw material extraction. The releasing industrial potential could be directed in the more important
branches of a economy.

Dating flint artifacts by electron spin resonance (ESR) should be possible if the artifact was heated during
manufacture, annealing any signal accumulated over geological time. It has been previously reported (Skinner
and Rudolph, 1996), based on several New World flint types, that heat-treatment of flint does not anneal the
signal completely. The investigation has been extended to Old World material, which also exhibits a residual
signal after heating that would affect the accuracy and precision of reported ages. In this paper we present
evidence that the residual signal is probably due to the presence of an amorphous silica component in the flint
matrix, which appears to carry an E' signal that is difficult to anneal completely. We also have found one type of
flint which does not have a significant amorphous component, and in which the E' ESR signal does reduce
essentially to zero on heating. We conclude that X-ray analysis may prove to be a useful screening test to
determine if ESR dating with the E' signal is likely to be problematic.

A great deal of scholarly studies have been devoted to the integration of the Alans into the North Caucasian
population, the formation and evolution of their settlements, culture and daily life . Yet, subsistence patterns of
Alanian settlements, particularly those of highland exploitation, have evaded the attention of researchers.

The exploration of the elevated areas along the Alikonovka river valley in the Kislodovsk hollow has shown
that mountain slopes were habitually turned into arable land through their artificial terracing. Before the joint
pedagogical-archaeological expeditions of 1995-1997 the terraced mountain slopes had never been subjected to
scientific examination, and the local geologists believed them to be swarded terraced outcrops of the armouring
layers of sand- and limestone.
Man-made terraces were levelled or slightly concave stepped shelves ca. 10-30 m wide and 20-300 m long. The
dirt for terracing was either brought from another slope or cut from the upper part of the same slope and
patterned into steps further down the hill. In the area under investigation one could encounter from one to seven
man-made terraces on a single slope.
The study of the terraced soil morphology and its comparison with that of standard virgin soils enabled us to
establish their artificial origin implied by the following traits:
a/ the thickness of modern humic horizons varies considerably within the levelled terraces areas, increasing
away from the overlying slope,
b/ the medium area as well as that transitional into the underlying slope often display buried horizons,
c/ the borderlines between the soil horizons within the terraces including their edges are frequently both clearcut and rectilinear, while those of virgin non-terraced soils on hill slopes are indistinct and wavy,
d/ in the upper soil horizons and on the surface of buried soil profiles one often encounters fragments of pottery,
e/ edges of certain terraces are either reinforced with stones or show traces of reinforcing constructions.
The slopes of the northern and western aspects were most meticulously ameliorated and cultivated owing to
their greater natural humidity, which was especially urgent under the arid conditions of the period in question.
The variety of terrace patterns and their wide distribution in the North Caucasus enable one to postulate the
existence of an original well-developed tradition of terrace agriculture among the Alanian tribes.

The exceptional yield of lipid molecules absorbed in sherds of Iron Age date (Easingwold, North Yorkshire,
U.K.) offers a range of approaches to understand their origin, including:
- localised examination of sherd lipid content
- application of novel extraction regimes
- comprehensive lipid fractionation techniques (isolation of sterols, purification of acyl lipids, etc.)
- a survey of the survival of other biomolecules.
These techniques have been applied with the aim of examining patterns and processes of lipid absorption and
the contribution of soil organic matter, exterior soots and original contents to the extracted lipid. A series of
simulation experiments have been designed to test specific processes. These involved reconstruction of cooking
events using experimental pots hand made from authentic raw materials.
The results of this study contribute to a better understanding of the relationships between absorbed organic
matter and archaeological ceramics. Clarification of some of these processes may guide future interpretation of
the often complex mixtures of lipids that survive in archaeological pottery.
240. Statistical Analysis Concerning the Determination of Some Probably
Measuring Units Utilised in the Ancient Dacian Buildings (1st c. B.C.-1st. c.
A.D.) in the Orastie Mountains (Romania)
Florin Stanescu*, Alexandru Sonoc**
138
Archaeometry '98, Budapest
The great civilizations of the Antiquity knew and used different measuring units and building modules, among
some length units like the Sumerian -Babilonian cubit (0,4953 m) on the Greek-Roman cubit ("cubitus"
=0,4436 m). The first part of the work is a presentation of the most known ancient measuring units, especially
of them which were utilised in the constructions of the of the temples and sanctuaries. There are presented ,
afterwards, some elements of the Dacian civilisation in the research area of this paper, a territory which is
situated in the region of the Dacian Kingdom's capital, Sarmisegetuza Regia, in the Orastie Mountains
(Southern Carpathians, Romania), as well as some evident Greek influences. The try to determine some length
units used by the ancient builders of the Dacian fortresses and sanctuaries - either North- Mediteranean, or
Central or West- European units didn't lead to the expected results. Therefore, the authors tried to proof the
existence of some length units and buildings modules at the Dacians. Mathematically the existence of an
length element which could be a common divisor for an ~ensemble, which is formated by an as much big
number of routes (lengths) of sanctuaries' interiors, doesn't solve the problem. It is obviously that a such
common divisor exists for every possible lengths’ ensembles-from the Antiquity to today. As a result , the
author's research method consists of a selection of the components of lengths’ ensembles, principally on the
existence criterion of a pillar demarcation, of the exactly division (without rest), as well as on the existence of
a signification for the wanted module. It was determined a length unity or building of 0,436 m, used probably in
the building of the Great Round Sanctuary, of the Little round Sanctuary, of the Small Rectangular Sanctuary,
as well of the as "The Andesite Sun" known sundial-altar. This size , respectively 0,436m, has some properties
which recommends it as length modular unity:
1. It is the single common divisor for which the division quotient of the sanctuary's dimension at the module’s
length is equal with the number of the sanctuary's border pillar; otherwise said to each border pillars on the
sanctuary's length or circumference correspond an unity-module.
2. The division of a dimensions' series of another sanctuaries of the Dacian capital's sacred zone to the
calculated module gives however whole numbers, too.
3. The size of this length unity or building module is very nearly to the Greek -Roman cubit (0,436m-0,4436m
in our actual units). Current researches on another sanctuary of the Orastie Mountains’ region, at Costesti and
Fetele Albe, will confirm or infirm this hypothesis.
241. Interpretation of δ18O values in fossil animal bones as a function of
preservation of hydroxiapatite, species, environment and climate
E. Stephan
Institut für Mineralogie, Petrologie und Geochemie, Univ. Tübingen, Wilhelmstrasse 56 72074 Tuebingen, Germany
Oxygen isotope compositions of bone phosphate (hydroxiapatite) mainly depend on the δ18O values of the
drinking water (meteoric) of the animals. This in turn correlates with the mean annual temperature allowing
δ18O of both recent and fossil animal bones to be related to temperature.
X-ray diffraction measurements of Pleistocene herbivore bones from sites in Germany and France demonstrate,
that the state of preservation of hydroxiapatite influences the hydroxiapatite. The standard deviation of
hydroxiapatite of well preserved fossil reindeer bones is as low as that of fresh bones from recent populations.
The hydroxiapatite values of poor preserved horse bones originating from the same archaeological horizon have
more scatter, although the arithmetic means of the two species are almost the same. The higher variations in
hydroxiapatite appear to be caused by recrystallisation of the hydroxiapatite during diagenesis. Preservation of
the hydroxiapatite should thus be taken into consideration when interpreting hydroxiapatite in fossil bones.
Hydroxiapatite can also be influenced by the uptake of drinking water and/or dietary water with higher 18O
content compared to the meteoric water. The hydroxiapatite of Pleistocene animal bones are often higher than
expected, because hydroxiapatite values reflect not only the δ18O of the meteoric water, but also depend on the
humidity. Leaf-water as well as water from small puddles and ponds which have experienced significant
evaporation, is commonly enriched in 18O relative to the precipitation. Furthermore differences in the diet and
water sources horses and reindeers from one archaeological unit may also lead to differences in their
hydroxiapatite values.

242. Multi Element Analysis Of Uruk Ceramics - Provenance and
Distribution

Research is currently underway on a selection of fourth millennium BC Uruk and Uruk related ceramics from
North Syria to shed light on the Uruk phenomenon and its cumulative effect on the Upper Euphrates River
Valley area. The main aim is to distinguish locally made ceramics from those which might be imported from
other areas in North Syria or South Mesopotamia. Much of the evidence for this expansive transformation is
ceramic. Yet in Syria, studies of what is referred to as Uruk and Uruk related pottery have been limited to
stylistic considerations. Central to this project is the identification of the sources of the clay minerals used in the
manufacture of Uruk style ceramics. Then it should be possible to determine the chronology, spatial extent and
nature of Uruk expansion to the west and its interaction with local cultures.
Sites of different status have been chosen to assess whether there was a hierarchy of full-fledged colonies with
exclusive Uruk ceramics, enclaves with mixed ceramics and stations with discrete concentrations of Uruk
ceramics amongst essentially local traditions. Selected sites include, Jerablus-Tahtani, Jebel Aruda, Habuba
Kabira South, Sheikh Hassan and others. The sample set comprises several hundred examples of corresponding
styles from each site as well as clay samples when possible. Techniques applied included INAA, ICP-MS, XRF,
XRD and petrographic analysis. Also under consideration was a comparison of the techniques themselves and
the accuracy and efficiency of each was carefully assessed.
243. New approaches to the analysis of resin and oil residues from
Canaanite amphorae transported to Egypt in the Late Bronze Age

Canaanite amphorae, believed to have been manufactured in Syria/Palestine, were widely exported throughout
the Mediterranean and are important indicators of the trade in bulk commodities during the Late Bronze Age (c.
1500-1050 BC). Sherds analysed in this study are from Egypt (Tell el-Amarna and Memphis). Based on
inscriptions the likely compositions are fatty acids and triglycerides (oils), diterpenoids (pine, cedar and/or fir)
and triterpenoids (Pistacia spp) resins, as well as the gum-resins frankincense (Boswellia spp.) and myrrh
(Commiphora spp.).
This project applies innovative extraction and derivatization methodologies for the identification of
'archaeological-invisible' organic commodities. Protocols have been developed for the extraction of both visible
(ca. 1 mg) and ceramic-absorbed (ca. 0.1 g) residues. TMTFTH, (m-trifluoro-methylphenyl)
trimethylammonium hydroxide, a reagent for the hydrolysis and methylation of esters and methylation of
carboxylic acids, is compared to diazomethane and analysis without derivatization. In comparison to
conventional extraction these smaller sample sizes and fewer stages results in a less time-consuming
methodology which decreases the possibility of introducing laboratory contaminants, lends itself to multiple
sampling of individual sherds and increases the number of analyses.
Fatty acids from oils and triterpenes from Pistacia have been recovered in archaeological material. A
concentration gradient of absorbed organic matter through the ceramic matrix has been established, further
reducing the sample size needed for analysis. Samples from the dry Amarna site exhibit excellent preservation
whilst those from the wet-dry site of Memphis show little or no preservation, even for ceramic-absorbed
material. Products of degradation have also been investigated. A comparison is made between residues and the
ceramic fabric.
The contribution of molecular information to our understanding of the movement of oils and resins is producing
valuable new data.

244. The characterisation, by lead isotopes and trace elements, of the ore
deposits of Cyprus & Sardinia, and its bearing on the possibility of the lead
isotope provenancing of copper alloys
Z.A. Stos-Gale, N.H. Gale
Research Laboratory for Archaeology, University of Oxford.
Cyprus has long been held to have been a very important ancient source of copper for the whole of the eastern
Mediterranean world, from the Bronze Age down to Roman times. For the Bronze Age there was little or no
direct evidence for this belief; nevertheless Mediterranean and Aegean archaeologists held this belief with some
passion, rarely admitting any other copper ore source into the discussion. Since 1982, lead isotope analysis has
held out the hope that such questions can be answered by this field of archaeological science, and that it could
in particular solve the long standing problem of the source(s) of copper for the Late Bronze Age copper ox-hide
ingots. However, from 1992 to 1996 there has been much controversial discussion of lead isotope
provenancing, including one paper in 1995 which claimed that lead isotope provenancing was not possible,
even for the copper ox-hide ingots.
Amongst the arguments advanced in 1995, perhaps the most telling one was that the isotopically analysed
copper ox-hide ingots did not, as had been claimed by Stos-Gale & Gale in 1994, match the 'lead isotope field'
for Cypriot ores, even for ox-hide ingots excavated in Cyprus itself. A further argument was that the lead
isotope compositions of Cypriot ores could not be distinguished from those of Sardinian ores. Whatever the
truth of these arguments, the advent of new ideas about the metallogenesis of Cypriot ores made it clear that the
lead isotope compositions of Cypriot ores might well be more complex than the relative paucity of analysed ore
samples from Cyprus had yet revealed.
Here we present new analyses of Cypriot and Sardinian ores which are discussed, in ways not so far published,
in terms of the geology and geophysics of the ore deposits. The ore analyses, in combination with those of
relevant artefacts, are applied to a thorough discussion of a number of critical aspects of the fundamental
hypotheses which underlie the concept of lead isotope provenancing of metals, in an attempt further to clarify
matters which have received much recent discussion. Finally it will be shown that lead isotope analysis is
indeed a viable way to provenance the copper in prehistoric copper alloy objects, and that at last a solution is at
hand to the long-standing problem of the source of the copper used to make the LBA copper ox-hide ingots
which are found in many Mediterranean sites.

Approach using Individual Lipids

Extensive studies of pottery recovered from archaeological sites have resulted in empirically derived sequences
representing changes in pottery types or characteristics through time. Termed seriation, this process is widely
used as a system of relative dating. Absolute dates, used to fix points in chronologies, are often derived from
radiocarbon dating of associated finds at the excavation (e.g. bone, carbonised seeds) or by dendrochronology.
Accelerator mass spectrometry (AMS) C-14 dating is regarded as a routine technique in archaeology and is
applicable to a wide range of biogenic materials e.g. wood, shell, teeth, bone, seeds, charred organics, etc. One
of the major problems in radiocarbon dating arises from contamination of samples during burial by absorption
of exogenous carbon containing components from the burial environment. The problem of contamination may
be overcome by purification of the organics into components that can be directly linked to the sample itself e.g.
cellulose from wood, or collagen from bone. Accurate C-14 dating of archaeological pottery remains an
ongoing area of research to the archaeologist; the ideal method would be to date carbon deposits directly
associated with or incorporated within the pottery itself.
It is well established that a wide range of lipids are detectable in appreciable concentrations in unglazed
archaeological ceramics. These derive largely from the processing, procurement and storage of foodstuffs
during vessel usage. The porous nature of the ceramic allows entrapment and affords considerable protection to
otherwise readily degradable compounds (Evershed, 1993). Recently, AMS has been successfully applied to the
141
Archaeometry '98, Budapest
dating of individual lipids from sedimentary organic matter (Eglinton et al, 1996). We are currently applying a
similar approach to date individual lipids preserved in archaeological pottery. Lipids possess several important
properties that make them favourable candidates for radiocarbon analysis:
1) their structures, distributions and 13C content are can be well characterised;
2) contaminants can be readily detected using gas chromatography mass spectrometry (GC/MS);
3) their hydrophobicity makes them relatively immobile in the burial environment, and
4) they possess young ages at the time of deposition.
Using automated preparative gas chromatography (PCGC), individual lipids can be isolated from extracts in
high purity and in sufficient concentrations (>200 mg) for high precision AMS dating. In this paper we will
discuss the methodology of compound specific radiocarbon analysis and present results obtained from studies
142

undertaken towards confirming relative chronologies and establishing secure sequences for selected British
pottery using the single compound approach.

Basin at Late Glacial/Postglacial Transition

Reconstruction of past environment and society interactions is one of the most difficult problems for
archeologists and paleoenvironmentalists. According to the paleoecological data some global climatic and
environmental changes developed and they transformed the habitats of the different human populations and
chances for their economy from the Last Glacial to Postglacial time. The global climatic and environmental
changes can be also detected in paleoecological and geoarcheological sites in the Carpathian Basin. This region
(including Hungary) is an important intermediate zone between Balkan peninsula and the western, eastern and
northern parts of Europe thus it occupies an important geographical position for understanding the interaction of
population infiltration, spreading of cultures and settling process and environmental changes in Europe.
Quartergeological, quarterpaleontological and recent climatological data suggest the Carpathian Basin has been
situated at a meeting point of different ecological and climatological zones from the Pleistocene up to the
present. From this ecological/paleoecological sticking point it follows that a mosaic-like environment and some
area-separating paleoecological barriers developed in the Carpathian Basin during the Late Quaternary. The
paleoecological and geoarcheological data suggest that the ancient geographical distribution of plants, animals,
soil-types and cultures with economy-types could be modified and limited by factors of these
paleoenvironmental mosaics and paleoecological barriers. According to the paleoecological data the most
important paleoecological/ paleoclimatological barrier was formed in the central part of the Carpathian Basin.
This paleoclimatic/paleoecological change-line with the fluvial valleys could transform migration directions of
the game animal herds and hunters following them in the analysed region before the Neolitization process.
There seems to be a contact between this paleoenvironment-line and the settling process Early Neolithic people
in the Carpathian Basin. Based on soil base rock types and submediterranean climatic effects, we can state this
environment change-line could stop the spreading of the Early Neolithic people northwards, who had mainly
Mediterranean growing experiences, because it limited the breeding of Mediterranean type domestic animal and
cultivation of Mediterranean type crops. Thus this paleoenvironment change-line formed an agroecological
barrier for Early Neolithic Mediterranean base agrotechnic and economy in the Carpathian Basin.
247. Archaometallurgical investigation of the LBA bronze objects in the
Carpathian Basin
Géza Szabó
Szekszárd, Hungary
Archaeometallurgical studies of objects from Late Bronze Age Studies of the Urnfield Cultures resulted in
many reports dealing with the tool set and products of metal processing, and general problems of the
production of bronze articles, basically from historical, typological points of view. However there has been less
opportunity and less attention paid to the study and evaluation of bronze articles within an interdisciplinary
background. The paper is aimed at approaching the subject from this less studied aspect.
In addition to the existing research results, the new methods, used scarcely or not at all, in the Central European
archaeological practice, offer broader understanding of earlier data. For instance, during the investigation of the
material not only the composition (in percentage) but also the microstructure, the type of the appliances, the
way of their use, etc. were assessed together, and the solutions guessed on the basis of observations, were
modelled in a foundry workshop. Moreover they were tested in the experimental archaeological camps under
143
Archaeometry '98, Budapest
conditions essentially analogous to the original ones. For demonstrating the serviceability of articles, in addition
to the practical tests, hardness studies also were performed firstly in the domestic practice of Bronze Age
studies. An additional problem is the high tin content revealed in the investigations of the last decades,
considerably exceeding the European average. This fact renders more difficult the integration of the domestic
data into the international system of archaeometallurgical research.
The exact determination of alloying metals and impurities, and the hardness value, shows the level of a
particular workshop and its serviceability characteristics, thus allowing evaluation of technological
characteristics in cases where the traditional methods fail. All this could facilitate outlining particular
workshops and workshop regions and could contribute to the solution of historical and chronological problems,
as well.

of Late Bronze Age

Data of researches performed so far demonstrate that within the today’s country border natural geographical
factors necessary for bronze manufacturing were available in the Bronze Age. Among the geological factors the
native copper and its ores along with tin, antimony and lead ores were present as well. The archaeological data absence of considerable number of mining tools, absence of large waste rocks and ash heaps - prove that no
significant ore mining and metallurgy on industrial scale was developed in our country. A part of the
archaeological data, however, indicate, that in some areas for example in the Mátra Mountains we should take
into consideration the processing of native copper or even a smaller amount of ore.
Above the simplest loaf, tongue, and bar-shaped raw material pieces, in the domestic find sets one can find
pieces of particular forms and destinations. For archaeological investigation pieces with easily traceable
territorial occurrence (due to their ornaments for which special manufacturing knowledge was needed) are of
particular importance.
Along with the special raw-materials, the source and transportation route of stone materials used during the
process of bronze production can also be well-traced. These materials of the casting moulds display a great
variety.
Then the Upper Permian-Lower Triassic sandstone, which in all likelihood has a similar facies with the red beds
of the same age occurring in the Carpathian Basin as well. Rocks similar to this fine grained, well-workable
material used for making the casting moulds can also be found in Hungary in the western part of the Mecsek
Mountains and the Upplands near Lake Balaton and North and West Europa. They have always enjoyed a great
preference among the stone materials used for architectural and sculptural purposes since the Ancient Times.
Among the casting moulds there is one made from light-colored, thin bedded sandstone, which compared to the
other rocks was deposited later during the history of the earth in the Miocene or Pliocene eras. Rocks of this age
are very common in the Carpathian Basin.
One of the moulds has a very typical Miocene material: fossil-bearing calcitic tuff, which in all likelihood
comes from the Tokaj Mts. It can also easily be recognised that the sand used for thinning the clay in case of
the clay casting moulds also comes from domestic localities. The examined cannelura rock used in the foundries
were also made from rocks, which are present in the Carpathian Basin.
The stone axe found at the Bölcske island locality and which might have been used in the foundry as well has a
very peculiar stone material: garnet gneiss. The material of the polished stone also from this locality is a
typically. Alpine-type rock which also occurs in Burgenland: micaceous quarzite.

**Soprintendenza Archaeologica Della Lombardia, Italy
During the last years a research project for determining of the provenance of raw materials employed for the
manufacture of prehistoric polished and ground stone tools in Hungary was conducted by the writers. Actually
thanks to the kind permission of the excavator, namely Dr. János Makkay, we have investigated samples from
the Neolithic sites of Méhtelek-Nádas in NE Hungary, Endrőd 39, 119, Szarvas 8, 23 in the Great Hungarian
Plain and Bicske-Galagonyás in Transdanubia.
The aim of the research was both to determine and describe the raw materials from which the prehistoric tools
were made and to establish a possible source, for a better understanding of the prehistoric exchange system and
the raw material procurement pattern.
Up to now almost 50 samples have been analysed in thin section and a few with X-ray diffraction. Different raw
materials have been determined, however most of them can be grouped into two basic categories:
Resistant and hard, fine grained and metamorphic rocks, employed for cutting-edged tools (axes, adzes and
chisels) and hammerstones, such as greenschists, hornfels, basalt, amaphitic andesite.
Siliceous and sedimentary rocks such as fine grained sandstone, metasandstone, siliceous magmatite and
quartzite for grinding tools.
The original locality of the studied rocks could be identified quite exactly for some samples. For the others, a
possible source can be suggested, In some cases the rock is available not far from the sites, in the form either of
raw material outcrops or in secondary, alluvial deposits. In other cases, the identified rocks do not occur in the
surroundings of the sites, thus they might have been acquired through an exchange system or a long distance
procurement pattern.
This study revealed the existence of a wide network of stone procurement since the Early Neolithic period and
the good, although empirical, knowledge which the prehistoric populations had of the basic characteristics of
the rocks they needed for specific tools.

The analysis of faunal remains from Teotihuacan site (Mexico) is important because there is no comparable
method for determining the significance of animals to the Teotihuacan population. The amount of strontium,
calcium and zinc deposited in the body parts of the animal depends on the rate of Sr, Ca and Zn passage through
biological membranes, and on the amount of these elements in their diet.
Samples of archaeological animal bones from Teotihuacan site were analysed for zinc, strontium and calcium.
Diagenetic contamination from the burial soil were considered to remove anortite and calcite particles from the
bone structures. The elemental analysis and diagenetic contamination was carried out by X-ray fluorescence, Xray diffractometry and scanning electronic microscopy. Analysis of the archaeological animal bones indicate
that identification of diagenetic contamination is critical in order to obtain useful paleonutrition information.
The results of trace element analysis indicate that Sr/Ca and Zn/Ca ratios are different between carnivorous,
herbivorous, omnivores and domestical animals from the Teotihuacan valley.

Excavations of an early La Tène settlement (450 to 300 BC) in NW Switzerland brought to light about 20'000
sherds belonging to more than 1500 vessels. Analyses by Polarisation Microscopy, X-ray Fluorescence and Xray Powder Diffractometry were carried out in two phases on 50 sherds. First, 25 sherds were selected among
three macroscopically defined wares (fine, medium, coarse). A second lot of 25 sherds was selected on the basis
of macroscopical resemblance to the groups defined among the first lot by mineralogical-chemical criteria. Does
the macroscopical and the mineralogical-chemical classification of the second lot lead to the same subdivisions?
Could macroscopical analyses reliably complete the classification of all the 1500 vessels? The first survey
revealed the presence of one predominant group (n=19)showing sufficient similarities to clays sampled around
the site to suggest a local origin. Differences among these sherds mainly in the grain-size and frequency of
inclusions indicate several subgroups (variety of local clays). The six samples which are clearly not part of the
predominant group are characterized by a particular fabric type and/or a different chemical composition, each
quite distinct. The second series confirmed the predominance of wares produced with locally available raw
materials. The predominant group, as well as foreign samples were identified by macroscopical and
mineralogical-chemical methods likewise. For this “coarse" classification macroscopical fabric analyses proved
reliable and could be applied to the totality of vessels and thus supply the basis for a statistical evaluation.
However, subgroups determined in the sample by macroscopical fabric analyses differ from those determined
by mineralogical-chemical analyses. The extrapolation therefore was not carried further.
252. The Technology and Development of 12th Century Ad Islamic
Polychrome Ceramics

During the twelfth century AD two techniques of polychrome decoration of glazed ceramics were developed in
the Islamic world. In Syria potters began to paint under an alkali glaze using metal-oxide pigments. This was
the beginning of the "underglaze-painting" technique that was also used in Iran for bichrome wares, and would
later become the predominant decorative technique in the Islamic World and in China. In Iran potters began to
paint over a tin-opacified glaze, again using metal-oxide pigments. This technique is often called minai (Arabic
for "enamelled") or haft rang (Persian for "many-coloured"), and was traditionally considered to be a lowtemperature enamelling technique.
Examination of contemporary Syrian and Iranian underglaze-painted wares has shown that while the Syrian
polychrome wares represent the true underglaze pigment-painting technique, the Iranian wares are actually a
more conservative slip-painting technique. This establishes precedence for the Syrian wares, although
traditionally the reverse has been thought to be the case. It is hypothesized that the Syrian technique derived
from an earlier splash-painting technique in lead-alkali glazes known as laqabi ware.
Examination of the Iranian overglaze-painted wares appears to indicate that they are not typical lowtemperature enamels at all, but in fact would have a higher maturation temperature than that of the glazes. The
pigments are generally not matured, so may have been fired at a low temperature, but this means that it is not
easily related to contemporary and earlier glass-enamelling techniques. It is hypothesized that this is an
independently developed technique perhaps derived from the lustre-painting technique. The prohibitive costs
would make this a short-lived ceramic technology.

Recently, interest has been generated in the development of the earliest ceramic technologies in both the Old
and New World, producing a welcome influx of new ideas and explanatory models (e.g. Barnett and Hoopes
1995). In the case of Greece, Vitelli's influential work has proposed that pottery production was restricted and
specialised from its very introduction (Vitelli 1995): the opposite of that expected from a evolutionary
146
Archaeometry '98, Budapest
viewpoint. Such important issues may only be clarified by looking beyond relative ceramic chronologies and
simple models of change, to a detailed analysis of pottery production and consumption.
In this effort, analytical work on ceramics has a major role to play. This paper presents the first results of the
study of perhaps the earliest known pottery in Europe, that from the Early Neolithic (EN) of Knossos (mid
seventh millennium BC). The analytical programme includes thin section petrography and scanning electron
microscopy of ceramics chosen through macroscopic examination of fabric and form. The pottery assemblage
has been characterised in terms of its mineralogy, paste preparation and its decorative and firing technology.
From the results of this extensive analytical programme, new information has been produced on whether
production was specialised at this early stage, to what extent the technology was 'developed', whether different
production traditions existed within the assemblage and finally on the existence of imported vessels. With no
known earlier occupation in Crete, the rich EN sequence at Knossos provides an ideal opportunity for
archaeometric work to investigate the introduction and development of an influential technology.

threads

Textiles had been decorated with gold threads for several thousand years. Pure gold or gold alloys were
replaced by about the 13-14th centuries A.D. by gilt silver threads made in different ways. One and both side
gilt narrow, thin silver strips and gilt silver wires were the basic constituents of these metal threads.
Gilding was carried out by hammering thin gold leaves onto the surface of a silver foil or the joint of the metals
was obtained by a soldering material. Mercury gilding and from the 19th century onward, galvanoplating were
also used. The determination of layer structure of the strips and wires can reveal the manufacturing technique
which is characteristic to the period of use.
The average width of the metal strips used in metal thread making is about 250-400 µm, their thickness is about
6-30 µm. The diameter of the wires varies between 50 and 100 µm . The width of the coatings rarely exceeds 2
µm.
From the early 90's attempts have been made for distinguishing the different metal coating techniques by
measuring the concentration of the different elements present in the metal - conducting a set of step by step
EPMA point analyses on the cross-section of the strip or wire, resulting in depth profiles. This method can
handle multicomponent and multilayer structures, but as the sample has to be embedded in a synthetic resin and
polished, problems of sampling and non-destructivity arise. Furthermore in the case of submicrometer coating
thickness the depth profiles reflects the lateral spread of exciting electron beam rather than the chemical
distribution of constituent concentrations.
These inconveniences can be avoided by utilising the fact, that the penetration of the exciting beam in the range
of the typical coating thickness. Analysing the gilt surface of the samples, decreasing the beam energy, the
apparent concentrations will be more and more characteristic to the composition of the layer. From the rate of
change of these concentration values the layer thickness can be deduced. In the case of pure layers the problem
can be treated using calibration curves, while the evaluation of multielement or graded layers requires a data
reduction program. As the method needs no special sample preparation, it is quick and non–destructive for the
sample.
In order to explore the possibilities and limitations of the methods gilt silver strips of metal thread samples taken
from textiles dated to the 15-20th centuries were analyzed and the results compared to those obtained by the
step by step analysis on the cross section.
It was found, that in the case of layer thickness greater than 1 µm (e.g. some 15th century Italian threads) line
profiling should be used, while the energy dependent measurement is clearly superior for thin layers of pure Au

(e.g. 20th century galvanoplated threads) down to thickness of 10-20 nm, well under the spatial resolution of
conventional profiling.

255. Technical examinations of medieval ferrous metallurgical finds found
in Hungarian sites (8 - 13th cent. AD)
Béla Török
University of Miskolc
The study gives account of chemical, metallographic and mineralogical examination of iron ores, slags from
smelting furnace and smithy workshop and furnace wall-fragment found in Hungarian sites of Medieval ironmaking. There is a connection with Dr. János Gömöri’s work (Museum of Sopron), who directed the most of
the excavations connected with the examined material, and put the samples at my disposal.
In the chemical examinations the samples were analysed by wet assay, X-ray fluorescent spectrometer,
gravimetric and spectrophotometric methods and LECO carbon-sulphur analyzer in the laboratories of the
Departure of Ferrous Metallurgy and the Departure of Analytical Chemistry of the University of Miskolc and at
METALCONTROL Kft. of Diósgyőr Steel Works. The samples also were examined by Scanning
electronmicroscope as a metallographic and by X-ray diffraction process as a mineralogical analysis at the
Departure of Physical Metallurgy and the Department of Mineralogy of the University of Miskolc.
The results afford help with gaining more knowledge of used technology and metallurgy of iron-making in that
ages. On the basis of the analysis some important conclusions can be drawn about characteristic of ores and the
different types of slags. The examinations often render help to typify the slags from metallurgical point of view
(smelting or forge slag; tap-slag or cinder etc.). This is one of the newest and richest collection of data from
examination of ferrous metallurgical finds from 8-13th century.

The examination of the sediments and chemical analyses of archaeological deposits provided useful data the
identification of cultural activities. Analyses of culturally modified sediments, using control profiles for
comparison, were applied to over 350 samples. The archaeological context integrated by domestic, ritual and
mortuary features, shoed successive cultural occupations that initiate during the terminal Classic period (700900 AD.) at the Teotihuacan site in Mexico. The application of particle size and chemical analyses - carbonates,
pH, phosphates, and color-helped to infer distinct types of activities within each occupation. Techniques were
incorporated to the archaeological methodology to form a solid corpus for the correlation with other
archaeological materials.

The relative potential of major, minor and trace elements in terms of their discriminative power amongst Cretan
Bronze Age pottery fabrics is examined in the present study. Seventy-two pottery samples were analysed from
three wares with calcareous fabrics (Vasiliki Ware, Grey Ware and Dark-on-Light Ware). They were
characterised and classified typologically and then by thin section petrography. The mineralogy of their nonplastic component is distinctive enough to allow confident ascription of provenance. In an exercise to further
evaluate the most effective mode of chemical discrimination within Crete, the same samples were then analysed
by instrumental neutron activation analysis. Statistical evaluation of the trace element data has revealed the
existence of three major chemical groups, each dominated by samples from a particular geographical region on
the island; the Mesara Plain, the South Coast and the Mirabello Bay area. However, the regional discrimination
from trace element data is not free form overlaps. This appears to be because the base clay of all three fabrics
consists of Neogene marls and the inclusions that discriminate the material petrographically do not seem to
affect significantly the trace element concentrations. As it became evident that the effect of Ca in the
discriminations is of importance, further analysis of the pottery samples for the determination of the major
elements was carried out by X-ray fluorescence. The results are compared with those by INAA and the
statistical analysis of the two subsets (major/minor elements and minor/trace elements) of variables are
presented.

In 1986 and 1987 a team of Turkish-French archaeologists launched a joint project of a systematic survey on
Hellenistic workshops of Knidos in the south-west corner of Turkey. The survey aimed to study the scale and
methods of production, as well as its spatial characteristics. It was decided to undertake an intensive survey to
examine various types of artifacts on the surface by unit of grids.
In order to detect disturbance effects of the spatial patterning, spatial autocorrelation on the type of analysis had
been tested employing quadrant methods for diagnostic types of potsherds. It was found that certain types of
artifacts occur in positive association that greatly effected by locational preferences of ceramic production
process through Hellenistic epoch.

Pozzolanic characteristics of the mortars used in a stone masonry structure have been studied to understand their
technological and durability characteristics. The stone masonry structure is a waterside palace built in Seljuk
Period (12th and 13th centuries) situated an Beysehir-Konya and known as Kubadabad Palace. It was first
excavated in 1965, extensive excavations have started 1980 and continued to the present.
Authentic mortars collected from the palace walls constructed at different periods have been analyzed for their
basic physical and mechanical properties as well as for their compositions.
Physical properties have been determined by RILEM Standard Test Methods and mechanical properties by
ISRM - Point Load Tests. The pozzolanic properties of the lime as a binder, the properties of the binder and
aggregate interface within the mortar, and, the mortar's interface with the building stone have been studied by
optical microscopy, Scanning Electron Microscopy (SEM) together with Energy Dispersive X-ray Analyzer
(EDAX), X-ray Diffraction Analysis (XRD) and Fourier Transform Infrared Spectroscopy (FTIR).
The mortars are porous, and their percent porosity values are in the range of 30 to 47. The bulk densities of
these mortars are in the range of 1.40 - 1.76 gr/cm3. Their uniaxial compressive strengths can be estimated to be
around 20 Mpa. Pozzolanic properties of the mortars have been established by the fillers based on the several
types of calcium and aluminium silicates observed in the binder and in the binder-aggregate interface and
mortar-stone interface, and the overall durability and compatibility characteristics of the mortar in relation to the
stone masonry.

260. The Origins and Dispersal of Maize Agriculture: A Review and
Critical Assessment of the Isotopic Evidence
Robert H. Tykot
University of South Florida
The application of stable isotope analysis of human skeletal remains to reconstructing ancient diet has now been
in practice for two decades. Initial studies focused on interpreting carbon isotope ratios, which primarily reflect
differences between C3 and C4 plants in human food chains, through the analysis of bone collagen. In the
Americas, the typical application has been documenting the dietary importance of maize, generally the only
significant C4 crop exploited by Native Americans. Most research efforts now also include the measurement of
nitrogen isotope ratios, which are ultimately dependent on how plants obtain their nitrogen(by symbiotic
bacterial fixation or from soil nitrates) but are also affected by rainfall and other local conditions. The combined
analysis of both carbon and nitrogen isotopes is especially critical for sorting out the consumption of marine
foods in areas where C4 crops such as maize also were available. It is also necessary to establish the isotopic
values for both marine and riverine/lacustrine resources on a local basis in order to interpret properly the human
bone isotope data. Most recently, it has been established that collagen carbon and nitrogen is derived primarily
from the protein portion of the diet, while bone apatite/tooth enamel carbon appears to be derived from all
dietary components. Since maize contains only 10% protein, small contributions of meat or seafood to Native
American diets would dominate the isotopic signal in bone collagen, thus requiring the analysis of both bone
collagen and apatite (or tooth enamel)to reconstruct ancient diet. In this paper, a critical synthesis of the isotopic
data accumulated in the last two decades for Native American diets will be presented, based on evidence from
countries including the United States, Canada, Mexico, the Caribbean, Belize, Honduras, Guatemala, Panama,
Venezuela, Ecuador, Peru and Argentina, and including isotopic data from the author's own as yet unpublished
research. In combination with traditional faunal, botanical, palynological and other data (e.g. pottery residues,
phytoliths) relevant to prehistoric maize use, a chronological and spatial model of the origins of maize
agriculture and its dispersal throughout the Americas will be formulated. Specific pathways of maize dispersal,
as well as diverse local patterns of consumption, will be presented. Lastly, areas for future research which will
explicitly test these hypotheses will be suggested.

For years, the composition of ceramic bodies were kept secret even among the representatives of the same
culture, probably, due to the technological competition. Therefore, it was not achieved to are producible data for
the ancient ceramic materials, and the questions on the origins of the different technologies are still discussed.
Furthermore, due to the complexity of the fundamental chemistry and physics of ceramic raw materials, the
structural changes which occur during the production process carry uncertainties, and thus "try and cut" method
is still valid in the ceramic technology. Consequently, studies done on the ancient ceramic artifacts give
valuable information for today ceramic technology.
In the present study, a multi disciplinary program of research on Iznik ceramics which refer to Ottoman tiles and
fritwares from 16th century A.D. were carried out. Iznik tiles were the main decorative elements of ceramics.
Firstly, a typological study of the pottery based on the excavation records, forms and motif assemblages and the
architectural investigation of construction assemblages and the full stylistic analysis of decorative variety of
tiles from dated monuments were done and the interdisciplinary data-base were planned.
The mineralogical composition of a sample of eighteen ceramic body was determined by XRD powder
technique. The result showed that the samples consisted mainly of quartz and admixture minerals such as
calcite, feldspar and a lesser amount of clay. Major and the minor elements of ceramic body and glaze were
determined by wet chemical analysis and Atomic Absorption technique.
The textural structure, glassy phase, size, shape and orientation of aggregates and particles as well as mineral
nature of ceramics were examined with petrographical analysis by observation of thin sections with SEM. The
150
Archaeometry '98, Budapest
bulk chemical compositions of glaze and body were determined in-situ energy dispersive X-ray analysis (EDA)
with SEM.
By using this combination of techniques, results show that Iznik pottery contains quartz-frit bodies, quartz-frit
slip, lead-soda glazes and underglaze decoration. The main specific elements of the decorative colours are
copper and iron. The greenish-blue and the reddish-brown colours are governed by these elements depending on
the glaze formula, kiln atmosphere and firing temperature. Manganese also contribute to brown colour and
chromium give the black outline of the decoration.
262. Origin of the Rosette-Stamped Royal Storage Jars from Ancient Judah
Joseph Yellin, Jane Cahill
The Hebrew University of Jerusalem
Excavations undertaken throughout the last century in southern Israel have produced more than 250 ceramic jar
handles bearing rosette stamp seal impressions. All of the well stratified rosette stamped vessels derive from
destruction levels marking the end of the Iron Age I confirming Aharoni's (1979: 400) idea that they succeeded
chronologically the lmlk stamp vessels of the 8th century BCE. Nevertheless, preliminary results from the
gamma-ray spectrometry following neutron capture (neutron activation analysis) performed on more than 90
rosette stamped vessels suggests that the rosette jars were manufactured from the same clays used a century
earlier to produce the lmlk stamped vessels. The neutron activation analysis performed on the rosette stamped
vessels both supplements the results of a similar study conducted more than a decade ago on lmlk - stamped
vessels (Mommsen, Perlman, and Yellin 1984: 89 - 113), and demonstrates a previously unrecognized
continuity in the ceramic industries of Judah during the 8th and 7th centuries BCE.

263. Evaluation of ancient diet: Dietary tracing by stable isotope analysis of
consumer tissues

The reconstruction of past human diets through isotopic analysis of archaeological human skeletons has been
successfully used for nearly two decades in tracking the adoption of C4 cultigens into C3 biomes, e.g. the origin
and spread of maize agriculture in the Americas. Contradictions between isotope data and other evidence
suggest that the relationship between the dietary importance of maize and the carbon isotope ratios of consumer
bone collagen (or hair, muscle, etc.) is not linear, as the initial model (the "scrambled egg" model) proposed.
Recent experiments with rats showed consumer apatite to reflect whole diet, rather than only energy
components, and consumer collagen to be dominated by, but not entirely formed from, dietary protein, thus
demonstrating the failing of the other model, the "Routing" model. A correct model requires an appreciation of
biochemistry.
In order to provide basic metabolic information for future archaeological interpretations of human diets,
experimental diets in this study have also been designed to simulate the introduction of maize to C3 biomes in
the Americas. We measured natural stable isotope ratios in the tissues (bone, muscle, hair) of pigs (large
omnivores with the same essential amino acids as humans) in order to study the biochemical routing from
dietary components to consumer tissues. We raised pigs on 13 different diets, using foods that are naturally
labelled with stable carbon and/or nitrogen isotopes. Their diets are designed to identify the dietary components
used in the synthesis of pig protein tissues, particularly where more than one protein source (animal and/or
plant) is available, and also to determine whether dietary carbon is averaged during the formation of mineral
bone carbonate. The full set of results on our first generation of pigs will be presented. Requirements in a new
biochemically informed model will be discussed. Final results will make it possible to interpret isotopic dietary
signatures in archaeological human skeletons with much greater accuracy in all global regions.

Problem of Discrimination between Parian and Proconnesian Marble

Laboratory of Archaeometry, NCSR "Demokritos", 153 10 Ag. Paraskevi , Attiki, Greece
The complex of Katapoliani Church, consisting of the central basilica devoted to Virgin Mary, the chapel of
Aghios Nikolaos, and the Baptestrerion which is said, according to the tradition, to be an imperial donation, is
dated to the middle sixth century AD.
Eighteen marble samples were taken from specific architectural elements from Katapoliani church such as
collumns, capitals, collumn bases and the kiborion. Archaeologists believe that some of them are made in
Proconnesian marble.
Marble samples were analyzed with the technics of Electron Paramagnetic Resonance Spectroscopy (EPR) and
optical microscopy. Characterisation, grouping and tracing of the possible provenance were the purposes of the
study. At the same time new Proconnesian and Parian geological samples of grey and white with grey striations
marble were added to the marble data bank of the Archaeometry Laboratory, NCSR "Demokritos", in order to
extend the range of material available for comparison.
The problem of discriminating between Parian and Proconnesian marble is well known to specialists in the
field and is still difficult even after the application of several scientific techniques.
Applying various combinations of parameters we were able to assign the provenance for ten pieces of
Katapoliani. The rest were unresolved leaving still both options open for future research.
265. Chemical Characterisation of Frankincense and Pine Resins from

Frankincense is the best known of the aromatic gum resins being used throughout the world as incense in
religious ceremonies. A wide range of ingredients may have been used by the ancient incense-maker and such
materials would have been important trading products in the region of Syria and Mesopotamia1. The earliest
archaeological evidence for the burning of incense comes from the Old Kingdom in Ancient Egypt, where
spoon-shaped incense burners with long handles have been found, however, in no case has chemical evidence
been provided for the exact resin which was burned.
We provide here the first chemical evidence for frankincense in the archaeological record obtained from the site
of the major frontier settlement of Qasr Ibrîm, Egyptian Nubia. The material came from levels associated with
the Post-Meroitic occupation of the site (c. 400 - 700 AD). The samples were recovered during sieving of the
room fills of a house.
The resins were characterised by a combination of gas chromatography (GC) and mass spectrometric (MS)
techniques, employing both solvent solubilisation and derivatisation, and pyrolysis techniques. The data
obtained show the presence of pentacyclic triterpenoid components that can be definitively linked to
frankincense. Especially characteristic are the α- and β-boswellic acids and the corresponding O-acetyl
derivatives that dominate the GC chromatograms. These data were supported by the detection of 24-nor-oleana3,12-diene and 24-nor-ursa-3,12-diene dominating the Curie-point (610°C) pyrolysates of the extracted
residues. The boswellic acids are characteristic of the fresh aromatic gum resins from trees of the genus
Boswellia. Other pieces pf amorphous resin recovered from the same excavations at Qasr Ibrîm were shown to
comprise tricyclic diterpenoid acids, including isopimaric acid, abietic acid and dehydroabietic acids, which
clearly indicate Pinaceous resin. Resins of this type, and their derivatives, have been reported previously at
archaeological sites, particularly as surface deposits in transport amphorae. The finding of two types of resin at
the same location in the Post-Meroitic house points to their use together in incense burning.

The identification of the pigments used in a manuscript can reveal important information for art historians,
conservators and restorers. One of the topics where pigment analysis can be helpful is the assignment to
different workshops of manuscripts of one collection. This was the case with the collection of Rafael de
Mercatellis (Flanders, late 15th - beginning 16th century). The colours of several paragraph-marks, running
titles, initials and illustrations in margin on different pages of different books where examined. These precious
works where sampled by a virtually non-destructive microsampling method. A combination of Ramanmicroscopy and Total Reflection X-Ray fluorescence (TXRF) made it possible to reconstruct the palettes used
in the manuscripts. Pigment characterization by two different techniques on the same small sample (less than 1
µg) was possible because of the high sensitivity of the methods used. Raman-microscopy is a fast and easy
method for the examination of the grains of the pigment, while TXRF leads to a more quantitative description of
the elemental composition of the samples. This delivers a good basis for the identification of the workshops of
the different manuscripts. This can lead to a new vision on the relationships between the manuscripts of the
Mercatellis collection.

The identification of ancient proteins found on different archaeological materials offers a new approach to
understanding the past. One of the proteins that can be detected and identified is haemoglobin. This presentation
will show the results of the biochemical and immunological analysis that we have developed in a experimental
model applied on a ceramic sculpture found at the "Templo Mayor", in Mexico City. This ceramic figure
represents the Mexican God of the Death: Miclantecutli, that was covered with blood in ritual ceremonies, as is
apparent in the Magliabechi Codex. The objective of our research is not determine the presence of the
haemoglobin on this piece, but try to identify whether this haemoglobin is human or not.

The movements of Mesoamerican Mexican populations through the Mexican territory have been motivated by
different natural and social causes.
The results of archaeological research show similar cultural characteristics between Teotihuacan and Tula
populations which are represented clearly by Coyotlatelco and some Mzapan ceramics (Epiclassic occupation).
This fact suggest that both populations could belong to the same genetic group in this Epiclassic occupation.
The objective of this work was to compare if the genetic frequencies of these populations are in agreement with
historical sources.

Hidalgo, México. The aDNA was amplified and hybridized for 5 genes as Amplitype Kit of Perkin Elmer
manual indicates.
Comparative analysis if genetic frequencies of these populations show differences in 3 of the 5 genes tested,
giving a probe of the genetic flow in those times.
269. Method of formalized comparative petrological analysis of ancient
ceramic and is application to the Greek amphora studies
S. Y. Vnukov
Institute of Archaeology, Dept. of Rescue Archeology Russian Academy of Sciences, Moscow Russia
The method of comparative petrological analysis of pottery was elaborated to group the samples applying
statistical criteria to clay composition of ceramic. It can be summarised in a formalised petrological description
of the samples using several indices. The quantitative data relating to these indices were estimated using a fourpoint system. A data matrix was compiled on the basis of this formalised description of the mineral
composition. Using this data matrix different coefficients of similarity between each pair of samples may be
then calculated. The results of the pair-based comparison were examined by hierarchical agglomerative
clustering and the group average clustering methods.
The general aim of the studies was to distinguish the petrological groups of classical ceramic and to determine
production centres of some amphorae types. 280 pottery samples from the main amphora production centres of
the Black Sea region and from some Aegean centres were used for the studies. They are dated from the 4th
century BC till the 3rd century AD. Both control samples from stamped amphorae and tiles of known centres
for References and samples of unknown origin were examined. It allowed to distinguish the petrological groups,
to connect these groups with morphological types of the vessels and with the certain amphorae's production
centres. Interesting data on the clay composition and technology of the samples were also obtained.

The copper mine on the Great Orme, north Wales, UK, has one of the largest and best preserved sequences of
Bronze Age workings in Europe. There is considerable evidence for the extraction of copper at this site, but few
traces of the subsequent stages in the copper production sequence (ore processing, smelting and metal working)
have been identified. If the nature of the exploitation at this mine during the second millennium BC is to be
conceptualised in greater detail, these sites of related activity must be found.
Copper mineralisation on the Orme is restricted to an area near the summit; therefore the identification of
elevated copper concentrations in other areas can indicate the debris of mining-related activity. A portable Xray Fluorescence Spectrometer was used to measure the copper concentration of soil deposits sampled at two
locations, Ffynnon Rhufeinig and Ffynnon Gaseg, identified by excavation (Wager 1997), topographic and
reconnaissance geophysical survey as potential copper ore processing sites. Analysis was carried out rapidly,
effectively and economically in the field.
The results demonstrate that portable field XRF is a highly effective tool for the identification of copper ore
processing sites on the Orme and at other locations with a similar detectable metal anomalies, particularly when
used together with topographic and geophysical surveying techniques.

The archaeological site La Cadena is situated near Quevedo in the northern Guayas basin in Ecuador. This area
which is part of the coastal plain is archaeologically still little known.
The La Cadena site consists of several mounds, so-called tolas. Within these layered mounds and in ground
between them artifacts, most commonly ceramic sherds and obsidian flakes, occur. The area around the site is
built up by fluvial sediments of the Estero Chollo and Estero Pise.
In order to contribute to the chronology of the archaeological layers as well to understand the function of the
mounds, luminescence dating was applied to ceramic sherds and sediments. The sherds were taken during the
excavation of two of the tolas and a test ditch in-between. Thermoluminescence dating was applied to the finegrain and quartz fractions of the potsherds. The TL dates range from the middle of the first century BC up to the
late first century AD. The chronological significance of these results will be discussed. Infrared stimulated
luminescence dating was applied to the fine-grain fraction of silty deposits from three profiles in the fluvial
sediments. The IRSL age data render basic information for the geoarchaeology of the site.

The aspartic acid racemization reaction has been used to date organic remains for over 20 years. However, the
validity of racemization dating has been questioned, probably due to some spectacular dates generated in the
70's. The most notable example was the dating of California palaeoindian skeletons (Bada et al., 1974)., which
suggested that humans had migrated into North America during the Upper Pleistocene (50-60k).
We believe that the problems with this method are caused by a lack of understanding of the underlying
mechanisms of the racemization reaction. We are examining the in vivo racemization of human dentine proteins
as a model for the post-mortem degradation processes in bones and teeth. The tooth acts as a unique
"temperature-controlled oven" in which to look at the diagenesis of proteins. The mechanisms of protein
degradation in metabolically isolated dentine are complex. Deamidation and isomerization reactions will occur
in addition to epimerization.
The D/L ratio of aspartic acid in dentine has been measured using Gas Chromatography. Artefacts caused by
inappropriate sample preparation and the role which various factors play in the rate of epimerization in dentine
have been investigated. Gaining a better understanding of the kinetics and optimising the experimental
procedures for analysing dentine will serve to improve the accuracy and reliability of the technique, which may
then be applied to dating and age at death determinations with more confidence.

The ancient black egg-shell pottery is a kind of very precious relics. It was made at the Longshan Culture period
(4300-4800 B. C.) in China. It is unimaginable that ancient people handle high technique very skilfully.
One sherd of black egg-shell pottery was measured by use of XRD, SEM, Raman spectrum, EDS and HREM.
A lot of graphite was found in the sherd by XRD and Raman spectrum. There are many fibre in the SEM photo.
EDS points out that the element of the fibre is Carbon. It probably is the earliest Carbon fibre. This discovery is
very interesting and of benefit to further researching how to make the black egg-shell pottery.

A lot of pottery Zun with big mouth at the Neolithic Age in China were found in Yushishi site of Mengcheng
city, Anhui Province, and Zhoujiazhuang and Dazhujiacun sites of Ju county, Shandong Province. There are
same engraved designs of "sun, moon and mountain " on the surfaces of pottery Zun with big mouth from
above-mentioned sites. It suggests there is some cultural relationship between above-mentioned two areas. It is
necessary to research on the provenance of pottery excavated from above-mentioned sites for exploring their
relationship.
11 sherds of Zun with big mouth in which 6 come from Yushishi site, 1 is from Zhoujiazhuang site, and 4
belong to Dazhujiacun site, were measured by using ICP and petrographic methods. The results show that the
petrographic compositions of above-mentioned two areas are very similar and their trace element data have
some overlap, but their petrographic structures exhibit obvious different features. The feature of pottery Zun
from Mengceng city has no or weak directional structure, but the sherds from Ju county have clear directional
structure. It seems that these pottery Zun was made from local soil, and the same engraved designs were only
related to the cultural custom or religious belief on Dawenkou areas.
This work is beneficial to research further on the source and stream of pottery Zun with big mouth at the
Neolithic age.

Black mirrors occupy an important position in the Chinese bronze cultural relics. According to the appearance
and the surface structure, they can be classified as two sorts: Heiqigu and common black mirrors (CBM).
Almost all of Heiqigu mirrors made during between Spring-Autumn and the Northern and Southern Dynasty,
and almost all of CBM appeared after Tang Dynasty. Tang Dynasty is an obvious line made known that there
are different preparing techniques for Heiqigu and CBM. Calculated result according to 2 theta/alpha film
diffraction on the surface of black mirrors and topography of SEM shows that there is outer part of surface
about 8.5 micron deep, which is only composed of SnO2. It suggested that the outer part of black mirror surface
came mainly from treatment with rich tin materials.
It is interesting that the grain size of SnO2 in the black mirror surface is about 5 nanom measured by SAXS and
lattice images of HREM. The Raman spectra reflects heavy lattice distortion in SnO2 particles. Ultrafine SnO2
films on the bronze substrate have been prepared by a improved sol-gel procedure and erosion of different
alkaline solutions. It was discussed for relation between the thickness and quality of the film and its preparing
procedure.

276. The identification of pigments in medieval manuscripts by Ramanmicroscopy

Instituut voor Nucleaire Wetenschappen, Proeftuinstraat 86, 9000 Gent, Belgium
The identification of pigments in old manuscripts, paintings, textiles etc. is from art historical interest, provides
restorers with important information and can help in detecting forgeries. Raman-microscopy is ideally suited for
these purposes.
The technique delivers vibrational spectra which can be considered as a fingerprint of the substance
investigated. Use is made of a low power laser beam, that is focused on the sample of the pigment layer or in
situ on the artefact itself.
Raman-microscopy (1) offers a number of unique features: Use can be made of microsamples ( < 1 g) that can
be taken without any visible damage to the artefact. Individual microscopic pigment grains can be analysed, no
special sample pre-treatment is required and the analysis is non destructive, thus can be used in a multi-method
approach. In this work the same micrograins were also analysed with total reflecting x-ray analysis and electron
microscopy, yielding a maximum of information from a minimum amount of sample. Mixtures can be
investigated easily, because it is possible to see the different micrometer-small particles under the microscope.
Thus it is possible to determine the composition of the sample semi-quantitatively. The latter information allows
for example to distinguish different artists based on the palette they used, a feature which is of great
significance in the study of manuscripts. In this work the use of the technique is demonstrated for the analysis of
a medieval manuscript (Brevarium Mayer van den Bergh, approx. 1480).
Nearly all coloured pigments from the manuscript could be identified by Raman-microscopy, and evidence was
found to support the thesis that different artists contributed to the illumination.

277. Antique Metalloenzymes

Ancient conservation techniques led to surprisingly well preserved large Mr biopolymers including nucleic
acids, carbohydrates and proteins. Apart from the exceedingly good conditions the molecular intactness should
likewise be reflected in the respective biological function of the examined component. It was attempted to
isolate both biochemically and immunologically active alkaline phosphatase from antique bone samples of
different archaeological sites and age. In particular specimen from pharaonic Egypt, bog finds, air drying and
seawater conservation being up to four thousand years of age were used.
Gel filtration, ion exchange and affinity chromatographies were employed to optimize the preparation of the
ancient enzyme resulting in a specific activity of up to 50 % to that of an enzyme from modern autopsy. The
possibility of microbial contamination was checked by employing specific monoclonal antibodies directed
against the human bone enzyme. Fortunately, ubiquitously present specified microorganism on the respective
ancient bones did not cross react with these antibodies while the ancient enzyme reacted with high specificity.
Alkaline phosphatase mimics could be excluded as in the presence of the inhibitors 1.10-phenanthroline and
homoarginine the enzyme activity was diminished. The presence of orthovanadate as a substrate analogon
aolished the catalytic function of the enzyme. Likewise heating to 100 C and replacement of Zinc(II) by
Cadmium(II) resulted in a dramatic loss of activity. In conclusion alkaline phosphatase appears to be a useful
marker enzyme in molecular archaeology.

Instrumental neutron activation of sixty-one copper-based metal samples from Mi'kmaq First Nations
archaeological sites at Northport, Pictou and Avonport in Nova Scotia show that all samples were of European
origin. There are two brass and one gun metal sample; all are of different trace element chemistries. The
remaining fifty-eight pieces of European copper displayed between six to thirteen different trace element
chemistries, implying that a minimum of this number of cooking pots was associated with the assemblage. Six
of the seven Northport copper samples match with different Pictou copper chemistries, linking the sites.
Since two Northport samples were from essentially whole pots, and since they match trace element groupings 1
and 2i, at least two pots of each of these chemistries must have arrived at Northport and Pictou. On the other
hand, the two copper samples from Avonport are chemically unique in this small collection, matching nothing
from Northport or Pictou.
279. Interpretation of black surface of ancient Chinese bronze mirrors

Ancient, beautifully-patterned Chines bronze mirrors which have shiny black surfaces and resist corrosion have
challenged archaeologists, curators, conservators and materials scientists for over sixty years. The major
archaeological/anthropological issue is: did craftsmen prepare the black surface to protect the underlying
bronze, or did it develop from burial in soil for 2000 years? Scientists have already formulated and proposed
answers to several relevant questions: What is the chemical composition of the black surface? (Mostly tin
dioxide). What is its microstructure? (Includes nanoscale tin dioxide particles). Why does it resist corrosion?
(Because of the oxide surface coating). Can it be replicated by laboratory experiments? (Yes, using, for
example, humic acid).
The present study had five goals: (1) to identify the specific minor compounds in the black coating using X-ray
diffraction software, (2) to confirm the presence of glassy matrix for particles by using transmission electron
microscopy and selected area electron diffraction, (4) to determine the elemental composition of not only the
mirror surface using Auger electron spectroscopy and SEM/EDS but also the patterned reverse side with some
soil particles still retained, (5) to repeat the XPS (ESCA) chemical analysis of the first few atomic layers, (6) to
determine what causes the black appearance.
A fragment of a typical Han Dynasty high-tin, black-surface, bronze mirror was analyzed using the above
techniques. Evidence of silica glass matrix was found, in which particles of many different phases are
embedded. In addition to the well-known bronze mirror near-surface compounds-cassiterite, cuprite and deltaphase, another compound developed from bronze was found: romarchite (SnO). Several others based on rocks
and minerals appeared in the glassy surface matrix: anorchite, tridymite, fayalite, rankinite, calc-flinta,
magnetite, cuprite and romarchite. The data collected from several techniques also confirmed that both front and
reverse mirror surfaces contain 7-8 atomic % iron. Since iron was removed from copper by successive smelting
processes when the mirrors were produced, its presence must be the result of soil adherence to the buried mirror
and diffusion into oxidizing surface. Cassiterite (tin oxide) containing iron impurity is known to be black, as is
the case with dozens of other minerals having Fe 2+. This argument and the presence of particles of
rock/mineral compounds embedded in the matrix combine to support the position that the black, oxidized
surface resulted from burial.

European copper-based metal kettles became an increasingly sought-after item in early European- Amerindian
fur trade transactions, with at least a small number of these vessels reaching Ontario Iroquoian groups by the
beginning of the seventeenth century. Portability may have contributed to their increased popularity.
Using accelerator mass spectrometry of precious metals, instrumental neutron activation analysis (INAA) of
trace elements and Pb isotopic studies, the objective was to establish broad copper-based metal types and to
assess the relative similarities and differences within the chemical sub-groups with respect to age, major, trace
and rare-earth elements and Pb isotopes.
Secondary goals included using the European copper and brass data to establish the distribution of different
chemistries around the site.
Eight hundred copper-based metal fragments, recovered from the Ball site in south-central Ontario, were subsampled at the Wilfrid Laurier University archaeology lab. A further sub-sample of four hundred and fifty items
from the Warminster site were obtained from the University of Toronto collections. A suite of samples from
each site were characterized and classified with the above-mentioned techniques. The data recovered show that
both indium-rich and indium-poor copper items were present on these sites, and that the brass samples,
examined also by electron microprobe analysis of polished shards, ranged in their zinc compositions from a few
percent to 30%. The seriation of the copper/brass ratio at these sites indicates that Ball is the earlier of the two
sites. Radiocarbon results on copper-preserved organics and thermoluminescence results from associated
pottery from these two sites are consistent with this interpretation. Pb results suggest that "Basque-like" copper
items from New Brunswick, Canada, approximately 1000 km to the northeast, are similar to artifacts from the
Ball site with respect to the geological formation ages of their parent deposit(s). The age appears to be
consistent with Swedish copper deposits thought to have been inactive from the fall of the Hanseatic League to
the time of the Reformation. This observation has implications for early New World historical trade and
population movements of Native groups.

Fresco pigments from a Byzantine church have been analyzed in an attempt to clarify painting phases within a
single building. The pigment samples were taken in 1994 with the permission of the Turkish Ministry of Culture
and the Aksaray Museum from the church known as Canli Kilise ("Bell Church") in central Turkey. The 11th
century church was constructed in three phases: 1/ the naos, 2/ the south narthex and the north narthex, and 3/
the parekklesion. All four spaces were decorated with frescoes, which are now in poor condition.
Our research objective was determine whether pigment analysis could confirm the relative chronology of
construction and decoration proposed by the archaeologist. Examination of the site suggested that the naos and
south narthex belong to the same phase of decoration (in other words, the naos may have been painted only
after the second construction phase). In addition, although the two parts of the narthex were constructed
simultaneously, they may not have been decorated at the same time. Finally, later repairs to some frescoes may
correspond to the original painting of other frescoes.
159
Archaeometry '98, Budapest
A program of analysis begun in 1995 has now been completed at the University of Illinois. XRD and SEM with
EDS were employed to characterize the mineral phases and major elements of red, green, and blue pigments
from all four parts of the church. The results indicate that different types of plaster were used in the naos and
south narthex (calcite, CaCO3) than in the rest of the building (gypsum, CaSO4 2H2O). Is this difference due to
accidental exposure to sulphur in the atmosphere, or is it due to a deliberate change in plaster materials by the
fresco painters? Also, the pigments do vary in composition between the older and newer parts of the building.
For example, the blue pigments show considerable variation, with the relatively rare ultramarine violet
(Na5HAl4Si6S4O24H2O) being present in the north narthex only, whereas copper-containing litidionite
(KNaCuSi4O10 and (CuNa2K2) Si3O7) is present in both the north narthex and the naos.
While the data may not support exactly the chronological sequence proposed, it is likely that the frescoes were
painted in several stages using different pigments.

St. (Cluj, Romania)

National History Museum of Transylvania, 2 C. Daicoviciu St. 3400 Cluj Napoca Romania
Noua culture is the last culture of the Bronze Age in Transylvania and makes the transition to the Hallstadt
period. The pottery belonging to Noua culture has a marked specificity: it is relatively poor in shape and
ornaments. As a result, up to now there has never been possible to create a complete typology of Noua pottery,
and in consequence, to structure this kind of pottery according to its periods of evolution. The almost total lack
of vertical stratigraphy in Noua settlements, has compelled us to look for alternative methods of classification.
The National History Museum of Transylvania has created the "Zeus" computer program designed to arrange
and classify the pottery in accordance with its essential characteristics. We experimented this procedure with the
pottery belonging to the biggest necropolis in Transylvania, the necropolis from Banatului St. in Cluj. All 50
graves were grouped in three series corresponding to three distinct periods in the existence of the necropolis.
The same computer program was also capable of classifying the graves in conformity with the anthropological
attributes of the dead. In this case four series of graves were determined, each representing specific properties
ascribed to the anthropological type.
283. Technical investigation of bricks from St Urban (13th century
Cistercian monastery, Lucerne, Switzerland): First Results of A Firing
Experiment
Sophie Wolf
Institute of Mineralogy and Petrography, University of Fribourg, Switzerland
The bricks from St Urban have been the focus of scientific enquiry for rather less than a decade. In 1995,
excavations at St. Urban monastery revealed 13th century bricks of extraordinary quality, design and size. The
majority of these red coloured bricks are 45 * 34 * 11 centimetres, making them extremely unusual building
materials. Firstly, the research focuses on the technical aspects of the manufacture of these bricks. As it seems
difficult to compare firing conditions in small electric kilns with production in the thirteenth century, a kiln was
built to imitate medieval brick making and firing. A firing experiment using this kiln was carried out in
September 1997.
During 10 days of firing the temperature distribution in the kiln was registered at 18 different positions. We also
measured the composition of the firing atmosphere by analysing 7 different gases (O2, CO2, CO, NO, NO2,
SO2, HC) as well as the gas temperature and velocity. To fire the kiln we used dry fir wood only. Maximum
temperatures reached about 1300 °C near the flue, and over 900 °C in the bricks.
Thin sections of the old and recent bricks were made in order to compare textures, grain size distribution and
quantity of the tempering material. The drying sensitivity and firing behaviour of the raw materials were also
studied. X-ray diffraction and Hg- porosimetry were used to analyse the mineralogical composition and porosity
as an indicator of the temperature gradient within the bricks. Finally, the characteristic values including water
absorption, compressive strength, bulk density were used to describe the technical and physical properties. The
comparison of the Cistercian bricks and their imitations allowed us to assess the production facilities and
conditions in the 13th century.

At present comparative lead isotope analyses of copper ores and artefacts is the only method available for
tracing the ore source of the copper used to make a prehistoric copper-alloy artefact (e.g. Gale and Stos-Gale
161
Archaeometry '98, Budapest
1989); chemical analyses are useless alone, but in special cases may strengthen an attribution made by lead
isotope analysis.
It has always been recognised that a more direct way to provenance copper might lie in using possible variations
of the isotopic composition of copper itself, but hitherto this possibility has not been investigated. Work will be
discussed which shows, by the difficult application of thermal ionisation mass spectrometry to copper, that
earlier work (Shields et al. 1965) reporting small differences in its isotopic composition in certain copper
minerals, though widely doubted, was in fact substantially correct. Applications to Bronze Age Mediterranean
artefacts which also show small isotopic variations will be examined. The confirmation of these effects using
much more precise ICPMS/magnetic sector multicollector mass spectrometric methods will be presented, and
an assessment given as to whether these effects may be used as an aid to provenancing, or whether the processes
of smelting, alloying, melting or fabrication make this impossible by changing the isotopic composition of
copper away from that in the relevant copper ores.

Fossil shells were collected from an Upper Pleistocene formation next to the Sanctuary of Hera at Perahora
(Central Greece). The hosting formation consists of marl limestone including significant fossil fauna. The
techniques of Thermo-luminescence (TL) and ESR were used.
The aim of this work is to test and compare the results of the dating and also to compare with the
biostratigraphic evolution during the Upper Pleistocene period in this area.
The samples which were to be dated using TL, were collected carefully with the appropriate precautions
(conditions of reduced day light). The shells found to be in aragonite form, by means of XRD, were rejected
and TL measurements were performed on the remaining of Ostrea edulis (Linnaeus 1758) shells (calcite form).
A new technique (foil technique) in TL dating was used, due to the advantages it offers in the estimation of the
palaeodose. Specifically, this technique permits the use of high heating rates which facilitate an increased TL
signal and also reduces significantly the spurious TL. For these reasons foil technique was the most suitable in
this case, as the samples had low sensitivity and thus gave signals very low to be measured by other means. This
was the first time the foil technique had been applied to calcite shells.
Fossil shells of the Glycymeris glycymeris (Linnaeus 1758) and Callista chione (Linnaeus 1758) were dated by
means of the ESR technique, using the datable signal at g=2.0033.
The results of both techniques are in close agreement and coincide with our knowledge of world climatic
changes during this period.

analysis (XRF) and physical characterisation (Hg-porosimetry) have permitted the establishment of three new
162
Archaeometry '98, Budapest
Reference groups. These groups have constituted the indispensable basis for the provenance and technological
study of stamped ceramics production from several sites (Lausanne-Vidy, Yverdon, Avenches, Martigny, Nyon,
Vindonissa).
The aim of this study is to define the geographical provenance of these products, to attribute them to the
workshops and to study craftsmen associations. Chemical data together with petrographic observations, phases
analysis and statistical elaboration, permit to understand and compare the characteristics of clays used by
different potters. Among all the sample (about 85) only 14 could be exactly attributed and permit to understand
potters' deplacements. The amounts of the sherds were not equal, as products of some craftsman are very rare.
Therefore, while some important and well-known potters (as Vepotalus, Villo, Faustus, Sabinus) could be
represented and studied by several analysis (from 7 up to 12) some others (Coius, Genialis, etc.) have been
studied only by few sherds (from 1 up to 6). Another aspect concerning some verification analysis have been
made on productions already analysed and known, as La Péniche and Florus group found in Martigny. They
confirm the equality of characteristics between Martigny group and Florus sherds and the presence of Iuvenis,
Pindarus, Iucundus potters in La Péniche workshop.
287. C-14 dating of the Mesolithic of East European forest zone (a critical
review)
Mickle G. Zhilin
Institute of Archaeology RAS, Dm. Ulyanov Street 19 117036 Moscow Russia
By now more than 100 C-14 dates are available from Mesolithic habitation sites and cemeteries, situated at the
territory of the forest zone of Eastern Europe, from Eastern Baltic countries to Urals and from Karelia to the
upper flow of the Dnieper, Oka and Don rivers. But various regions of this large territory are not equally
studied. More than 30 dates are known from the Eastern Baltic, about the same from Karelia and from Upper
Volga, about 10 from the Eastern Onega lake region. Only several dates are known from other parts.
The second problem is reliability of many dates, obtained at various laboratories, especially of those, produced
in the sixties and seventies. In many instances publications give no information about what material was dated.
Relationship of the dating and cultural layer is also not certain in many cases. Some recent, yet unpublished
dates from the author's excavations will also be introduced and discussed. The aim of the paper is to select
reliable dates of Mesolithic sites and cemeteries and to discuss the chronology of the Mesolithic of East
European forest zone, comparing the C-14 data with dates, achieved by other methods.
288. The Technical Arrangement of the Bath-houses in the Golden Horde
and its Genesis
E.D. Zilivinskaya
Moscow State Institute of Archaeology, Russia
The culture of the Golden Horde, one of the largest states which arose as a result of Mongol conquests,
represents a specific symbiosis of the nomad way of life and developed urbanism. More than 100 cities which
were founded by the Golden Horde khans in the second half of 13th - first half of 14th A.C. possessed all the
features and institutes of a typical medieval town. One of such features were public bath-houses; apart from
their hygienic functions they also served as a specific ``clubs'' for different social levels. Rich farmsteads
included also private bath-houses.
Nowadays more then 20 such structures were excavated in the Golden Horde cities. Independently of the
planing and external decoration all the Golden Horde bath-houses had the similar technical arrangement. All of
them had a sub-flour heating. To warm the floor in the bath-rooms, the system of heat conducting channels was
built beneath. For this purpose the surface was carefully levelled, upon it small pillars (of 70-90 cm high) were
erected and upon these the floor slabs were mounted. Hot air came to the sub-floor space through magistral
channels from the fire chamber situated in the opposite to the entrance side of the building. The same fire
chamber served also for heating the water. The water was supplied to the bath-rooms through ceramic pipes. In
order to reduce the heat loss bath-houses were sank into the ground and had massive walls. Such an
arrangement of heating was first applied in Ancient Rome. Later it was used in Byzantium; with Arab
conquests it came to the Orient and got the further specific development there. Oriental bath-houses (hammam)
163
Archaeometry '98, Budapest
differ from Roman ones considerably in functions, planning and the structure of rooms. At the same time in the
Middle Ages the bath-houses of the Roman tradition co-existed with the Oriental ones. In the Golden Horde
cities both the two types of the bath-houses were found. The choice of the bath-house planning was usually
determined by several (social etc.) factors.

290. Archaeometrical method in the study of the nautical signalization on
Roman Limes in the Iron-Gate area.
Radmila Zotovic, Sofija Petkovic
Institut Archéologique, 11000. Beograd.
The Limes on Danube in the Iron-Gate gorge was founded during the Roman conquest of the Central Balkan
region. The construction of the road and fortifications with permanent garrison along the Danube was
completed in the last quarter of the 1st century A.D. This was confirmed by two stone Tablets of Tiberius from
33-34 A.D. and Claudius from 46. A.D. found at Gospodin Vir. Several phases of the construction were the
following up to the renovation of Justinian I. in the 6th century A.D.
The function of the fortifications in the Iron Gate’s section of Limes could be observed in the military - strategic
scope, but also from the economical point of view. We could presume that these fortresses on Danube had the
important merchant communication and provided the overcoming of the natural obstacles on this way.
The Iron Gate is consisted of the series of gorges at the Danube, section from Golubac to Karataš. It has nearly
vertical slopes, over 800 m high in some places, intersected by small river’s valleys linking the Danube bank
with the inland of Upper Moesia.
The great density of the Roman fortifications in the Iron Gate gorge is obvious at the first glance. Thirty
fortresses were recorded by archaeological research, up to now, between Golubac (Cuppae) and Karataš
(Diana), at the right bank of Danube. The average distance between these fortifications is about 5 km in the airline. In the Upper Gorge (Gornja Klisura), from Gospodin Vir up to Donji Milanovac (Taliata) the
concentration of the Roman strongholds in even greater.
The position of the fortifications in the Iron Gate described, provided the facility of communication among the
garrisons, by optical signalization at the first place. The signals could have been sent by natural or artificial light
sources, amplified with the system of mirrors. Meanwhile, some of the fortifications were separated by cliffs,
which made an optical barrier. The fortresses on the left bank of Danube, as well as the ships with military crew
controlling the navigation, could have been the transmitter of these signals.
The methods we used were: 1. the analysis of the possibilities of the optical signalization and 2. the statistical
analysis of distances and density of the fortifications on the Danube section in question.
The fortifications on the Roman Limes in the Iron Gate, according to the results of this analysis, had at least
three functions:
164
Archaeometry '98, Budapest
1. to ensure the Frontier
2. to control the navigation on Danube in the Iron Gate and
3. as nautical stations for signalization, providing the safe sailing in the Iron Gate gorge.

The source of amorphous organic substances surviving on Mesolithic artefacts or as isolated aggregates (often
with human tooth impressions) has long been sought. Indeed investigation of such materials from Scandinavian
bog sites dates back to the nineteenth century. More recently, the application of new analytical approaches
offers a unique opportunity to study for the first time, a large number of samples. Whereas substances such as
birch bark tar, conifer wood tar and beeswax have been identified in European Neolithic contexts, comparative
studies of Mesolithic material have until now been minimal.
To this end we report results from a project funded by the British Academy, focusing on the characterization of
natural products of Mesolithic date in northern Europe. Material from Star Carr, Yorkshire, and a number of
Scandinavian sites including Ageröd V, Sweden, Barmose, Denmark, and Huseby Klev, Sweden has been
studied. These samples date from the early Maglemose to the Ertebolle period. In addition an early example of a
Neolithic adhesive from the Sweet Track (Somerset Levels) has been analysed.
The techniques used include gas chromatography and gas chromatography/mass spectrometry. The manufacture
and characterization of modern reference materials is also being carried out. Identification of these samples
allows consideration of the use of specific natural resources throughout the Mesolithic. Questions relating to
possible social and medicinal functions of tars and resins as well as their technological functions are also being
addressed.
292. Technology and organization of Inka pottery production: neutron
activation analysis and Mössbauer spectroscopy studies

In the Andean Inka empire (ca. 1400-1532 A.D.) skilled artisans were relocated to provincial administrative
centers to produce goods for the state. During recent fieldwork at two Inka centers on the North Coast of Peru,
archaeologists discovered a series of state pottery workshops. Inka, local, and hybrid styles of pottery were
manufactured using a variety of techniques. In addition, molds, firing pits, and unfired pottery were also found.
Research at these sites provides the unique opportunity to document manufacturing techniques and to examine
how production decisions might have been directed by the state.
Archaeometric analyses focus on reconstructing the technology and organization of production. Thin section
and neutron activation analysis in combination with Moessbauer spectroscopy examine raw material selection
and firing technology. Both sherds and pieces of unfired pottery were
analyzed. Results indicate that local
and Inka style vessels did not significantly differ in raw materials. However, large Inka jars used to serve beer
at major state festivals were fired using a nonlocal (Inka) technique. Likewise, molds used to manufacture these
politically important jars are highly standardized in composition, suggesting state-directed decisionmaking.
Results of the archaeometric study contribute to an understanding of the Inka political economy and illustrate
the importance of locating and examining manufacturing locations.

The survey presented here took place on the NE slopes of Taurus Mountains at 1500-2000 m above sea level, in
the actual districts of Hadim and Bozkir (Konya, Turkey), ancient Rough Cilicia or Northern Isauria, covering
an area of about 400 km2 .
During the excavation and cleaning operations done by the Konya Museum in the ancient site of Astra, which is
situated within the borders of this region, were found large amounts of minerals, metals, slags and fragments of
a furnace. This work gave us the opportunity to start a research in an area lacking of archaeometallurgical
surveys.
The geological setting of the region reveals that it was very reach in lead, zinc and iron ores, and possibly used
for ancient metal production since some slag deposit and ancient mining galleries were found by geologists. In
the seventies some mining companies tried to produce metals following a primitive method, but Ottoman
archives from the 19th century attest the effective production of lead as well as silver and gold.
On the basis of these informations we started our survey with the following goals:
1. - to localize ancient sites and areas of mining and metal production,
2. - to record the evidences of metallurgical activities (mining galleries, deposits of slags, furnaces, crucibles,
etc.),
3. - to collect and analyze samples to get more information about:
a - the mining activities and metal production steps.
b - the cultural context,
c - the chronological framework,
4. - to restore the ancient mining life, the circulation and uses of minerals and metals.
During few weeks in the summers of 1994 and 1996, we were able to localize at least fifteen ancient sites
mostly unrecorded and possibly dating from roman period, and to limit four main sections by mining galleries
and metal preparation-production areas. Twenty of the metallurgical samples (metals, slags and minerals) and
two of the wood samples submitted to laboratory analyses gave information useful for a preliminary
reconstruction of the archaeometallurgical and chronological framework. The results obtained after this short
term work encouraged us to carry on our research.
294. Study of black layer on ancient Chinese bronzes
Quanyu Wang, John Merkel
Institute of Archaeology, UCL, Gordon Square 31-34, London WC1H 0PY
A large number of bronze objects were unearthed from the nobility tombs of the Jin State, one of the vast states
during 1027-450B.C. at Qucun site, Shanxi, China from 1992 to 1994. Bronze fragments from the tombs are
examined by macroscopic observation, metallographic observation, XRD analysis and SEM/microprobe
analysis. The most interest is that a black layer is present on the surface of the original metal for some of these
bronzes. The question has been raised: is the black layer intentional patination or natural corrosion product?
What was the technique if it was a intentional patination? How did it form if it was from the corrosion process.
This paper try to give a answer to this question.
