Portable EDXRF analysis of a mud brick necropolis enclosure: evidence of work organization,El Hibeh,Middle Egypt

The geochemical and sedimentological compositions of mud brick from a feature called the Square Enclosure in the eastern desert necropolis of the ancient town site of El Hibeh, Egypt, were investigated along with surface sediments from the local Nile floodplain for the purpose of establishing possible sources of the mud brick. Geochemical examination was undertaken with a portable EDXRF spectrometer; a field portable sedimentological laboratory was used to collect grain size, mineralogy, and strength analysis data. Results of the analyses produced evidence of work organization relating to the construction of the Square Enclosure. This discovery is the first archaeological evidence of work organization from the mud brick of ancient Egyptian structures and provides a valuable contribution to our knowledge of ancient Egyptian work organizational practices.     

A Clay source provenance survey in Northwest Alaska: Late Holocene ceramic production in the Arctic

Ceramic compositional analysis can contribute to the study of late Holocene Arctic hunter-gatherer social interaction through reconstruction of past ceramic distribution patterns. The results of an ethnographically informed clay source survey in Northwest Alaska are presented here. The survey provided contextual data on clay depositional environments, clay variability, and local environmental factors that influenced pre-contact clay availability. Geochemical analysis of clays and tempers clarified the location of ceramic production zones. Concurrence between survey results and ethnographic data highlights the persistence of clay knowledge despite post-contact absence of pottery making. This research demonstrates that ethnographically informed source survey can aid in interpreting ceramic geochemical data and yield important insights into pre-contact ceramic production processes.     

THE UTILIZATION OF TRACE CHEMICAL COMPOSITION TO CORRELATE BRITISH POST-MEDIEVAL POTTERY WITH EUROPEAN KILN SITE MATERIALS

This study uses X-ray fluorescent analysis to compare the trace chemical composition of seventeen pottery sherds excavated from sites in Britain with the trace analyses of twenty four sherds from continental sources. Results indicate that certain elements, notably zirconium, titanium, rubidium, and strontium show little variation within a particular sherd and are consistent among samples from the same source. Certain other elements appear to show wide variation which is possibly attributable to firing conditions, burial or is connected with the glaze. The comparisons of analyses indicate that nine of the seventeen British sherds can be closely correlated with particular continental sources. Tentative correlation is suggested for five sherds. The remaining three sherds clearly do not come from any of the sources investigated.     

A Late Roman ceramic production from Pompeii

The Via Lepanto site is one of the best examples showing how the Vesuvian region was partially reconstructed and earlier re-occupied after Vesuvius's eruption in the year 79 AD. The large amount of ceramic finds illustrates the typology in use in this area during the IV and V century AD. Analyses were focused on table and cooking ware productions. Archaeometric data were obtained using chemical and minero-petrographical methods (OM, XRD, XRF and SEM). Grain size measurements using Image Analyses on thin sections and a geochemical comparison with clayey deposits outcropping in the Campania region permitted the identification of the raw materials used for these pottery productions. XRD and SEM completed the data set, establishing the protocols used for pottery production in the Pompeii area during Late Roman period. The Via Lepanto site was part of an exchange network of markets with a periodic frequency, where locally produced and imported pottery was sold, indicating a flourishing network of exchanges spanning short, medium and long distances.     

Understanding ceramic variability: an archaeometrical interpretation of the Classical and Hellenistic ceramics at Düzen Tepe and Sagalassos (Southwest Turkey)

Within the aim of contributing to the artisanal craft history at Sagalassos (SW-Turkey), an archaeometric programme including thin section analysis, ICP-MS and multivariate statistics was developed to define the variability on a provenance and/or technological scale of the Classical/Hellenistic ceramic assemblage of Sagalassos and Düzen Tepe. The obtained data were used to evaluate the extent and variation of local pottery production. Petrographic and geochemical analysis as a grouping technique proves to be conditional for documenting the variation in ceramic wares present on both archaeological sites. Elemental evidence supports local production activities between Classical and Hellenistic times, documenting a deliberate change in treatment of raw materials during the Late Hellenistic period in function of ware groups.     

Potter’s Wheel in the Iron Age in Central Europe: Process or Product Innovation?

The use of a rotational device for forming ceramic objects represents a fundamental innovation in pottery technology. This work addresses aspects of the transmission of this technological innovation on the basis of technological and provenance analysis of Iron Age pottery in a selected region of Eastern Bohemia. The possible trajectories of the innovative process are approximated specifically through the polarities between product and process innovation and transmission of cultural traits in open and closed learning networks. Apart from standard methods of petrographic and geochemical analysis, this analysis employs innovative methodology for identification of pottery-forming techniques. The results indicate the effects of various mechanisms of cultural transmission which shaped the evolution of techniques in the Iron Age society. The technological changes can be explained by shifting accents on product and process performance characteristics in changing selective environments.     

The geochemical diversity of neogene clay deposits in Crete and its implications for provenance studies of Minoan pottery*

The determination of provenance probably forms the primary role of geochemical analyses in archaeological ceramic studies. In what has comprised a successful field of study, the ultimate basis for such research has been the comparison of pottery compositions with the geochemical diversity displayed by clay deposits within a given study area. Although such studies are now common, the understanding of chemical and mineralogical variability in ceramic raw materials has been somewhat neglected, with the dominance of assumptions rather than the actual analysis of clays. In this paper, a study is presented of Neogene clays in Crete (Greece), a clay type commonly used in ancient and modern pottery production. Sixty‐one samples were taken from 28 locations in the central and eastern parts of the island, to reveal both intra‐ and inter‐deposit variability. In one deposit chosen for multiple sampling, the 14 samples display great variability in the alkali elements, Fe and Co, and to a lesser extent in the REEs. Many of the geographically separate deposits differ from each other in chemical composition, with Eastern Cretan deposits showing higher REE concentrations and higher Th/Sc ratios, whereas Central Cretan deposits of younger geological stages are characterized by a lower Th/U ratio. Mineralogical analysis by XRD is used to explain aspects of the geochemical variability of the clays.     

Mineralogical analysis and provenancing of ancient ceramics using automated SEM-EDS analysis (QEMSCAN®): a pilot study on LB I pottery from Akrotiri,Thera

A wide range of existing mineralogical and geochemical methodologies such as optical microscopy, X-ray diffraction, manual scanning electron microscopy, ICP-MS and INAA have been utilised in the analysis of ancient ceramics, in attempts to elucidate patterns of regional trade and interaction. However, advances in automated scanning electron microscopy with linked energy dispersive spectrometers (SEM-EDS) have created the potential to offer a seamless combination of textural and mineralogical data based on the acquisition of energy dispersive spectra that has so far been unattainable with existing techniques. In this pilot study on pottery from the Cycladic Bronze Age site of Akrotiri (Thera), we have quantified the mineralogy of the ceramics based on automated SEM-EDS using QEMSCAN^® technology and imaged the textures of the ceramics through compositional mapping. Thirteen samples were analysed and, based upon the automated analysis, four groups of ceramic compositions are defined. These data are consistent with, but also refine, previous traditional petrographic examination of the ceramic samples, and enable the likely provenance of the raw materials used in the ceramic manufacture to be identified. This technique allows the acquisition of fully quantitative data, not only for the larger inclusions within the ceramics but also for the typically finer-grained groundmass/matrix, whilst also providing the overall texture of the ceramic.     

The Santa María pottery of El Bolsón valley (Catamarca,Argentina): Compositional characterization and implications on the elaboration processes,ca. 1000–1600 ce

The results obtained from the multi-analytic compositional characterization of ceramic pastes and paints of the Santa María style, from the El Bolsón valley (Belén Department, Catamarca Province, Argentina), are presented here. This pottery style had a wide regional distribution in Northwestern Argentina between ca. 1000 and1600 ce and is characterized by its complex iconography painted in black, cream and red. The analyses show that the containers correspond to the technical tradition of using grog temper and suggest that its manufacture involved a double firing process. This reveals a new practice for the time.     

Composition of white paste inlay on the pottery from sites of the 10th–8th centuries bce in the northern Pontic region

For the first time, the mineralogical–geochemical compositions of the white paste inlay found on vessels from sites (10th–8th centuries bce ) in the northern Pontic region are investigated. Samples of the white paste on vessels from settlements, burials of sedentary groups and graves of early nomads were analysed by means of scanning electron microscopy with energy-dispersive X-ray spectrometry (SEM-EDX) and X-ray diffraction (XRD) methods. Between the 10th and eighth centuries bce , various innovations occurred in the working area. Iron processing technology and the manufacture of iron products also appeared. Other innovations were changes in the manufacturing technology of ceramics. A high-quality, polished/burnished surface and ornaments with white paste inlay are characteristic of this pottery. When collating white paste mixtures of different European sites, similarities in the preparation of white paste recipes for vessels from the Balkan and northern Pontic regions are evident. During the Early Iron Age, further changes in the manufacture of the white paste were discovered in the northern Pontic region, namely the application of high-temperature firing to obtain more resistant synthesized material such as calcium alumosilicates and silicates (wollastonite). The development of iron metallurgy in this period could provide a basis for the elaboration of new techniques in ceramic manufacture.     

Roman pottery production in Civitas Tungrorum,central Belgium,during the first–third centuries ce

Aspects of Roman pottery production at the workshops of Kontich, Tienen, Rumst, Grobbendonk and Clavier-Vervoz in the Civitas Tungrorum of central Belgium are explored. A total of 150 wasters from five sites were studied macroscopically, as well as via a combination of thin-section petrography, geochemistry and scanning electron microscopy, in order to gain insights into ceramic technology and aspects of the organization of production. Particular emphasis was given to the individual technological sequences and shared strategies of raw material selection, paste preparation and firing employed at the five adjacent sites. The integration of petrographic and geochemical data permitted the establishment of compositional reference groups for the Roman kiln sites of Civitas Tungrorum, which can be used to track their products within the surrounding landscape.     

Ceramics, Ethnohistory, and Ethnography: Locating Meaning in Southern African Iron Age Ceramic Assemblages

For ceramics to be relevant in the Southern African Iron Age, archaeologists must broaden their theoretical base to include social and other contexts when interpreting material culture items such as pottery. Pottery remains critical in understanding cultural dynamics in the region for the past two millennia, but current usage is narrow in scope. Using ethnohistorical data and archaeological examples from South Africa and Zimbabwe, we argue that pottery provides valuable information on the region's Iron Age, if archaeologists address the social meaning of ceramic assemblages. Ceramic production among rural communities provides the basis on which a wide range of social issues are discussed and used to critique pottery recovered from archaeology. Ethnography suggests that ceramic assemblages are context specific, and archaeologists are cautioned against making generic statements on the basis of similarities of vessel shape and decoration motif.     

Ceramic form and function in the Neolithic Gulf. A view from Bahra 1

This paper discusses the possible functions of ceramic vessels in the Neolithic Gulf, based on new data from the Ubaid-related settlement of Bahra 1 (Kuwait). Two pottery groups identified at the site—Ubaid Ware and Coarse Red Ware—are found in great numbers and variety of forms which provides grounds for a reconsideration of the role of pottery vessels in the societies of the Gulf. Analysis of this material reveals a more varied function of pottery vessels compared to that suggested in earlier studies. It was also possible to define the function of certain pottery vessels in more detail, both in their economic and social context.     

LEAD ISOTOPE ANALYSIS OF TANG SANCAI POTTERY GLAZES FROM GONGYI KILN,HENAN PROVINCE AND HUANGBAO KILN,SHAANXI PROVINCE

Through the use of MC–ICP–MS, this study analyses the lead isotope ratios of 19 Tang Sancai pottery glazes unearthed from the Gongyi and Huangbao kiln sites. According to their different lead isotope ratios, the two kilns can be grouped separately. The research also suggests that the Gongyi and Huangbao kilns are independent production centres of Tang Sancai in the Tang Dynasty. The data from the Huangbao kiln indicates that the lead in the glazes originates from the Northern China geochemical province, while the data from Gongyi kiln suggests its source as the Yangtze geochemical province. Furthermore, the results obtained for the Tang Sancai pottery indicate that the lead sources for glaze making of these two kilns were very consistent, which suggests that lead isotope analysis could be a helpful method to identify the kilns producing Tang Sancai artefacts.     

Investigating the production and distribution of plain ware pottery in the Samoan archipelago with laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS)

This paper presents a provenance study of 170 ceramic artifacts and 21 ceramic tiles from three islands in the Samoan archipelago using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS). Our analyses confirm that LA-ICP-MS can be used to differentiate between clay formations on a single island. We identify different distribution patterns for pottery recovered from lowland and highland sites on Tutuila Island. We also examine evidence for movement of pottery between islands, and find only limited evidence for such movement. Our findings suggest dynamic patterns of prehistoric interaction and site use that need to be evaluated with further data from across the archipelago.     

Ceramic Production in the Kur River Basin (Fars,Iran) During the Middle to Late Second Millennium bce: A Geochemical and Technological Characterization

A total of 119 middle to late second millennium bce pottery samples from six sites in the Kur River Basin (Fars, Iran) were examined to characterize these ceramics and reconstruct their manufacturing technology and the origin of the primary materials. For this, a combined study of handheld XRF and thin‐section petrography was performed. The geochemical signatures of these ceramics were defined and interpreted in their archaeological and geological framework, resulting in the determination of different production processes and clay types used for four ceramic wares (Middle Elamite, Qaleh, Shogha and Taimuran) and the identification of possible outcrops used for Shogha–Taimuran production.     

Investigating ancient technology and ceramic composition at Al-Khidr site (Failaka Island,Kuwait): Geochemical analyses of Bronze Age pottery by pXRF and thin-section petrographic analyses

Pottery assemblages from the site of Al-Khidr on Failaka Island, Kuwait, were analysed in order to reconstruct the chemical composition of Bronze Age wares and to build a mineralogical database of Bronze Age pottery dated from Failaka Periods 1–3B (2000–1650 BCE). A total of 145 ceramic sherds from Al-Khidr, as well as reference groups, were analysed by non-destructive portable X-ray fluorescence (pXRF) spectrometry. Preliminarily petrographic thin-section analysis was applied to four samples to reconstruct possible clay paste recipes and to identify raw materials. The results indicate that geochemical analyses can successfully distinguish subgroups within a typological category of ceramic assemblages. The results identified two subgroups within the Al-Khidr typological category: the Dilmun Barbar tradition and the Mesopotamian tradition. Future comparative compositional studies can be conducted to explore other aspects of craft specialisation, such as ceramic technological choices and possibly the influence of sociopolitical units.     

Pottery Use-Alteration as an Indicator of Socioeconomic Status: An Ethnoarchaeological Study of the Gamo of Ethiopia

The use of a pottery vessel leaves markers on the ceramic wall that can inform archaeologists how the vessel functioned in the past. At present, archaeologists have little information for understanding how use-alteration reflects the complex nature of ceramic function and socioeconomic status. I conducted a 2-year ethnoarchaeological research project among the Gamo people of southwestern Ethiopia, who continue to produce and use pottery on a daily basis. This research indicates that interior surface attrition occurs primarily on pottery vessels used in wealthy households because of fermentation processes from high-status foods. Thus, the Gamo example suggests that there is a relationship between ceramic use-alteration and household socioeconomic status.     

LAST ORDERS: CHOOSING POTTERY FOR FUNERALS IN ROMAN ESSEX

Summary.   This paper examines ceramic vessels from Roman-period funerary contexts in Essex. Using correspondence analysis, it charts changes in the choice of funerary pottery and isolates the elements in pottery assemblages that unite or differentiate sites. The paper finds that the status of sites can be distinguished on ceramic grounds, reflecting cultural differences in life. Jars and beakers are characteristic of settlement cemeteries, while cups are more typical of high-status burials. Flagons and samian ware are common between them. Underlying funerary traditions are rooted in continuity from the Late Iron Age, rather than post-conquest change. The study also suggests that funerary pottery was selected out of the supply intended for domestic use.     

Dealing for Dollars

Abstract

Archaeologists in the field and laboratory commonly record colors of pottery using Munsell or other standard codes. These data are seldom used for more than primary documentation of individual items or to summarize common colors of a defined type or ware. Despite the many factors affecting pottery color it is possible to use this information to investigate patterns of variation within ceramic traditions and between contemporary sites, and to establish the degree of standardization or quality control achieved by ancient potters. Significant trends can be identified in the range and proportional occurrence of colors on assemblages of Red Polished Ware, the common pottery of the Early and Middle Cypriot Bronze Age (ca. 2300–1650 B.C.). These have implications for establishing the degree of control exercised over the process of manufacture and are relevant to discussions of the context of pottery production technology transfer, and inter-site relationships.
