A Study Of The Firing Technique Of Pottery From Kaman‐Kalehöyük,Turkey, by Synchrotron Radiation‐Induced Fluorescence X‐Ray Absorption Near‐Edge Structure (Xanes) Analysis*

Fe K‐XANES spectra of a series of pottery sherds excavated from the archaeological site of Kaman‐Kalehöyük, Turkey, were measured to reveal the firing technique of the pottery. The analysis disclosed relationships among the chemical form of the iron, the firing conditions and the colour of the pottery. The pottery referred to as ‘Grey Ware’ found at this site was classified into two groups according to the chemical form of the iron. Also, it was revealed that the Iron Age pottery referred to as ‘Cream Ware’ was produced first under reducing conditions, and then fired under oxidizing conditions.     

PROVENANCING OF LIGHTWEIGHT VOLCANIC STONES USED IN ANCIENT ROMAN CONCRETE VAULTING: EVIDENCE FROM TURKEY AND TUNISIA

The mastery of the use of lightweight rocks in concrete as a means of controlling the thrusts of large‐scale vaults was among the most important contributions of the Roman builders to the development of vaulted architecture. The string of volcanoes along the Tyrrhenian coast of Italy produced a variety of lightweight rocks, which allowed the builders in Rome to develop highly sophisticated ways of manipulating form and mass to create stable structures. The use of lighter rocks in vaults and heavier in foundations occurs from the mid‐first century bc in Rome, but the systematic use of imported lightweight rocks only began in the early second century ad under Trajan ( Lancaster 2005 , 59–64). Soon thereafter, the technique of using lightweight stones to build large vaults spread throughout the empire, usually to areas that had a local source of lightweight volcanic material. However, there was also a seaborne trade in lightweight rocks to areas that did not have local sources of such material. The intention of our analysis is to determine as precisely as possible the provenance of the lightweight stones used in vaulting of two areas of the Mediterranean, modern Turkey (ancient Cilicia) and Tunisia (ancient Africa Proconsularis), and thus to provide a better understanding of the nature of this trade.     

The Source Provenance of Bronze Age and Roman pottery from Cyprus

Archaeological interpretations of ancient economies have been strengthened by chemical analyses of ceramics, which provide the clearest evidence for economic activity, and comprise both the objects of exchange and its means. Pottery is often manufactured from local materials, but its compositional diversity typically prevents significant patterns of resource utilization from being identified. Centrally located and positioned on traditional shipping routes, Cyprus maintained ties with and supplied a variety of distinctive ceramic products to the major commercial centres in the eastern Mediterranean throughout Antiquity. We analysed two Cypriot .ne wares and a variety of utilitarian pottery, as well as samples of extant Cypriot clays to determine source provenance. These chemical analyses provide an objective indication of the origins of ancient (Bronze Age and Roman) ceramics manufactured on Cyprus. The distribution of the probable clay sources and the links between pottery style and the material environment also afford a perspective on the spatial organization of large‐scale pottery production on the island. Compositional analysis provides the means to assemble geographies of pottery production and to unravel the interregional system of exchange that operated in Antiquity, but the ability to accomplish these tasks is predicated on systematic analyses of ceramic products and raw materials that are found far beyond the bounds of individual archaeological sites.     

Technology Transfer at the Periphery of the Mycenaean World: The Cases of Mycenaean Pottery Found in Central Macedonia (Greece) and the Plain of Sybaris (Italy)*

The study of technology transfer in pottery production to the periphery of the Mycenaean world has been addressed by considering two different areas, southern Italy and central Macedonia. Technological features such as ceramic paste, decoration and firing have been determined for different ceramic groups established according to provenance criteria. The studies of technology and provenance have been performed following an archaeometric approach, using neutron activation analysis, petrographic analysis, X‐ray diffraction and scanning electron microscopy. The results have revealed the existence of two different models. On the one hand, southern Italy seems to exhibit a more organized pottery production, which follows a Mycenaean‐like technology, while in central Macedonia production is probably more varied, being based in part on the technology of the local tradition.     

FOSSIL DIATOMS AND THEIR SIGNIFICANCE IN ARCHAEOLOGICAL RESEARCH

Summary. The relationship between environmental archaeology and diatom analysis, a well established technique in palaeoecology, is explored. The development of diatom analysis for palaeoenvironmental reconstruction is briefly considered and flow diagrams are presented to illustrate laboratory techniques. Examples of research in Mexico, North America, Britain and Europe are discussed to illustrate the potential of diatom analysis as a means of assessing human impact on the environment, notably lake water quality, and as a means of elucidating the palaeoenvironmental conditions under which archaeological sediments have accumulated. Consideration is also given to the role of diatom analysis in examining land/sea-level changes, especially those which may have affected prehistoric resource use, and to its significance in the reconstruction of local environments in and around archaeological sites. Finally, the potential of fossil diatoms for provenancing pottery is explored with particular reference to Dutch and Finnish examples.     

PINE RESINS AND POTTERY SEALING: ANALYSIS OF ABSORBED AND VISIBLE POTTERY RESIDUES FROM CENTRAL NEW YORK STATE*

Analysis was performed on absorbed and visible residues from 21 New York State prehistoric pottery sherds dating from 2905 ± 35 bp (Intcal04) (1256–998 cal bc ) to 425 ± 40 bp (Intcal04) (1417–1626 cal ad ). The use of pine resin was detected in 10 of 12 absorbed residue samples and 11 of 17 sherds subjected to visible residue analysis. It seems likely that the pots were resin‐sealed to make them more impermeable, constituting the first chemical evidence of extensive resin‐sealing in North America. A comparison of the results of absorbed and visible residues from eight of the sherds indicates that the two kinds of residue provide complementary evidence of vessel use.     

Commitment,Objectivity and Accountability to Communities: Priorities for 21st-Century Archaeology

Abstract

It is no longer possible to ignore the unprecedented levels of destruction resulting from development projects imposed by multinational corporations and governments. In this context, it is important to address the role archaeology and related professions, such as heritage management, play from the perspective both of the threat to physical heritage and our relationship with affected communities. This paper explores ways in which professionals can learn to work in a mutually accountable way with communities opposing destructive development, and together seek alternatives to development which threatens lives, livelihoods, culture, and environment. Case studies from the Boyne Valley and Tara in Ireland, Il?su dam in Turkey and the Oaxaca valley in Mexico, illustrate some of the issues. The implications of the growing privatization of professions, particularly for communities in the Third World whose poverty undermines their power to refuse even the most globally devastating developments, making it imperative that professionals look again at what we aim to accomplish and how much we are actually accomplishing it. As professionals we cannot afford to be ignorant of what communities want, need and are entitled to in order to develop and flourish. Archaeology and people's cultural roots are not separable from these questions.     

Melian obsidian in NW Turkey: Evidence for early Neolithic trade

Abstract

Archaeological investigations carried out at the Early Neolithic coastal site of Co?kuntepe in northwestern Turkey yielded an assemblage of 110 obsidian artifacts displaying the macroscopic characteristics of the well-known obsidian deposits on the Cycladic island of Melos. Analysis of three samples from this homogeneous obsidian assemblage using both X-Ray Fluorescence and Laser Ablation High Resolution Inductively Coupled Plasma Mass Spectrometry confirmed that these artifacts were derived from Melos. The presence of these Melian obsidian artifacts at Co?kuntepe, along with a few pieces with central Anatolian macroscopic characteristics, is intriguing because intensive production of tools made of local flint was also identified at the site through the analysis of surface scatters. This finding raises the question of the status of obsidian and associated procurement systems. The presence of obsidian can be also used to argue that certain coastal villages acted as nodes of exchange for Aegean seafarers at times in the late 7th millennium B.C.     

Technological Features of Roman Terra Sigillata from Gallic and Italian Centres of Production

Technological features of sherds of Roman terra sigillata were studied. The sherds analysed represented products of workshops which were most probably located in Gaul, central Italy, north-west Italy and the plain of the river Po. Equivalent firing temperatures were estimated by colour measurement, X-ray diffraction and thermal expansion measurement; in addition, the chemical and morphological features of the red sintered slips were investigated using scanning electron microscopy coupled with energy dispersive X-ray microanalysis. The combined results suggest that, relative to northern Italian products,terra sigillata from Gaul and central Italy was made by potters who were more successful in modifying slip composition and controlling firing temperature to obtain highly sintered slips. Northern Italian potters seem to have worked their clays less successfully and fired them at temperatures which were too low to overcome the limited presence of fluxes in the slip.     

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.

Black Gloss Pottery: Production Sites and Technology in Northern Etruria,Part II: Gloss Technology

The present study aims to understand the reasons for the visual differences of black gloss pottery found in northern Etruria. The results obtained by conventional (scanning electron microscope, electron microprobe) and synchrotron (X‐ray diffraction, X‐ray absorption spectroscopy) techniques indicate that the thickness, porosity or chemical composition of the different types of gloss cannot be used as the principal distinguishing factor. The size of quartz or feldspar crystals may well be a critical factor responsible for the matt effect in some samples, while the range of mixtures of iron compounds indicated by XRD and XAS could be the reason for differences in colour and reflectivity. The Fe L‐edge XAS results in particular show that a correlation does exist between the oxidation state characteristics and the visual appearance. The Si, Fe and Al contents seem to further discriminate the different types of gloss that have differing visual appearances.
