THE BEGINNINGS OF ISLAMIC STONEPASTE TECHNOLOGY*

A multidisciplinary programme of research on Islamic pottery has been focused on questions of the dating, provenance and technology of Islamic pottery. One particular question has been the development of stonepaste, a material made primarily of crushed quartz with added frit-glass and clay. The combination of the different approaches of this study has revealed early foundations for the technology in ninth-century AD Iraq, apparently originating in the clay ceramic rather than the ‘Egyptian faience’ tradition. Subsequent and final practice developed in tenth- and eleventh-century AD Egypt. This technology becomes the primary body for all fine Islamic ceramics.     

THE PROVENANCE AND TECHNOLOGY OF NEAR EASTERN GLASS: OXYGEN ISOTOPES BY LASER FLUORINATION AS A COMPLEMENT TO STRONTIUM*

The ability to make rapid measurements on small samples using laser fluorination enhances the potential of oxygen isotopes in the investigation of early inorganic materials and technologies. δ¹⁸O and ⁸⁷Sr/⁸⁶Sr values are presented for glass from two primary production sites, four secondary production sites and a consumer site in the Near East, dating from Late Antiquity to the medieval period. δ¹⁸O is in general slightly less effective than ⁸⁷Sr/⁸⁶Sr in discriminating between sources, as the spread of measured values from a single source is somewhat broader relative to the available range. However, while ⁸⁷Sr/⁸⁶Sr is derived predominantly from either the lime‐bearing fraction of the glass‐making sand or the plant ash used as a source of alkali, δ¹⁸O derives mainly from the silica. Thus the two measurements can provide complementary information. A comparison of δ¹⁸O for late Roman – Islamic glasses made on the coast of Syria–Palestine with those of previously analysed glasses from Roman Europe suggests that the European glasses are relatively enriched in ¹⁸O. This appears to contradict the view that most Roman glass was made using Levantine sand and possible interpretations are discussed.     

Behavioural and Taphonomic Patterning at Katanda 9: a Middle Stone Age Site, Kivu Province, Zaire

Katanda 9, an open air Middle Stone Age site, contains a dense vertically compressed accumulation of lithic and faunal remains. The physical state of these materials indicates prolonged surface exposure before burial and the site shares essential characteristics therefore with many Lower and Middle Stone Age and Lower and Middle Palaeolithic occurrences in Africa and Eurasia. An important goal of archaeological research is to determine what, if any, anthropogenic signature can be extracted from distributional data and this article utilizes Katanda 9 to suggest an approach to such spatial analysis. It employs a bottom-up, top-down strategy which works in sequential fashion first to determine and control for taphonomic bias and secondly to fit the resultant pattern to models of hominid behaviour. It proposes that questions be posed in nested hierarchical fashion and that probabilities of correctness be assessed. It concludes that the distribution of materials observed at Katanda is most consistent with a nuclear family pattern.     

ANALYTICAL INVESTIGATION OF ARCHAEOLOGICAL POWDERS FROM GÖLTEPE (TURKEY)*

Nine powder samples originating from the archaeometallurgical she in Göltepe, southern central Turkey, have been analysed. Bulk analyses, using X-ray fluorescence and X-ruy photoelectron spectroscopy, and single particle analyses, using electron probe X-ray microanalysis, were carried out. The analyses were focused on determining the inorganic elemental composition of the samples and the distribution of particle types in the nine powder samples. In addition, the powder samples were classified on the basis of their elemental composition using multivariate techniques. The objective of this study was to characterize the powder samples and to establish an association with archaeological data from the site     

THE PETROGRAPHY AND CHEMISTRY OF THIN‐WALLED WARE FROM AN HELLENISTIC– ROMAN SITE AT SEGESTA (SICILY)*

Samples of Roman thin‐walled ware from Segesta (northwestern Sicily), dating back to the early Imperial period, were studied by optical microscopy (OM) and Neutron Activation Analysis (NAA). Up to now, this class of Roman fine tableware has only occasionally been evaluated archaeometrically. Nevertheless, numerous production centres are believed to have been simultaneously active in the western Mediterranean area. Petrographic and chemical data seem to be in agreement with the archaeological hypothesis of local manufacture in Segesta for most of the analysed samples, through a comparison with kiln wasters and local raw materials. The effectiveness of thin‐section petrography for determining the provenance of such a tiny tempered class of pottery and the integrated use of two different grouping procedures (petrography and chemistry) were also tested.     

COOKING WARES IN ANCIENT SYRIA (FIRST TO 10TH CENTURIES ad): RECONSTRUCTING THE PRODUCTION CONTEXTS FROM THE CONSUMPTION SITES

This paper deals with Brittle Ware, a cooking ware product that appears to have been highly standardized and widely distributed in Syria during the Roman and the Byzantine periods. The study intends to determine the distribution of Brittle Ware through time and space, by combining typology and a thorough examination of the fabrics in the field, using binocular microscopy (n = 2807 diagnostic fragments). Based on the fabric groupings, petrological and chemical analyses were then undertaken. Resting on an archaeological background and several analytical methods, this paper aims at going beyond a limited provenance study, by characterizing the Brittle Ware production system and thus providing some insights into the economy of ancient Syria.     

A GEOARCHAEOLOGICAL STUDY OF THE ANCIENT QUARRIES OF SIDI GHEDAMSY ISLAND (MONASTIR,TUNISIA)

Amongst a large number of ancient quarries scattered along the North African coast, those at Sidi Ghedamsy (Monastir, Tunisia) have supplied building stones of Pliocene age. Two lithofacies have been distinguished in the quarry faces: (i) fine sandy limestone, which has been used in the construction of Roman and Arabic monuments; and (ii) porous and coarse limy sandstone, which is of bad quality for construction. Laboratory analysis results confirm that the exploitation of stone in antiquity was well focused on the levels containing the first type. This is confirmed by geotechnical tests, which show that the fine sandy limestone is harder and less porous than the coarse limy sandstone. Extraction of these stones began in the Roman period. The Romans exploited the quarries using steel tools that permitted the extraction of blocks from several levels. In the eighth century, Arabic quarry workers continued the stone extraction using the same technique, but they produced blocks of small and medium size. Statistical measurements have been done on the quarry faces and on the walls of the Ribat in order to understand the degree of conformity between the dimensions of the extracted blocks and those used for building, and ultimately to attempt to date the quarries and the construction of the Ribat.     

PETROGRAPHY AND PROVENANCE INTERPRETATION OF THE STONE MOULDS FOR BRONZE DAGGERS FROM THE GALDONG PREHISTORIC SITE, REPUBLIC OF KOREA*

This paper presents material characteristics and raw material provenance of the stone moulds for bronze slender daggers from Galdong. This type of bronze dagger is uniquely distributed in the Korean Peninsula and these stone moulds were the first to be found by excavation. The stone moulds were made of igneous hornblendite with course-grained holocrystalline textures. Based on petrological, mineralogical and geochemical characteristics, the original rock materials of the moulds were inferred to be derived from the Jangsu or Namwon areas which are about 50 km away from the excavation site. It is a notable achievement that this provenance study confirmed the domestic production of Korean-styled daggers.     

SELECTION AND HEATING OF COLOURING MATERIALS IN THE MOUSTERIAN LEVEL OF ES‐SKHUL (c. 100 000 YEARS BP,MOUNT CARMEL,ISRAEL)

The transformation of yellow goethite into red hematite by heating has long been assumed for Palaeolithic red artefacts excavated close to fireplaces. However, this transformation is extremely rare. Using SEM–FEG–EDX, PIXE–PIGE, TEM and μXRD, we characterized the mineralogical and chemical compositions of four microsamples of colouring materials from the Mousterian layer B in the es‐Skhul rock‐shelter, from about 100 kya ago. For some colouring materials, the Mousterian people of es‐Skhul chose to gather remote yellow lumps for heating. Their significant transport distance provides evidence of the possible high cultural value of these colouring materials for transformation into red pigments.     

NEW PETROGRAPHIC EVIDENCE PERTAINING TO CERAMIC PRODUCTION AND IMPORTATION AT THE OLMEC SITE OF SAN LORENZO*

This paper reports the results of petrographic analyses of 41 new pottery thin sections from San Lorenzo. The resulting compositional data provide an important new context for evaluating the disputed status of carved vessels previously identified as imports to the site. By comparing local and Oaxaca highlands pottery, the disputed vessels are shown to be (a) compositionally distinct from San Lorenzo pottery and (b) similar to highland pottery. San Lorenzo was not just an exporter but also an importer of pottery vessels, a finding relevant to consideration of San Lorenzo's role in the production and exchange of ceramics in Early Formative Mesoamerica.
