Woodland period ceramic provenance and the exchange of Swift Creek Complicated Stamped vessels in the southeastern United States

Results of instrumental neutron activation analysis (INAA) of Middle and Late Woodland pottery (n = 313) and clay (n = 22) samples from northeastern Florida and southeastern Georgia are presented. Assemblages in this region include Swift Creek Complicated Stamped pottery that preserves unique evidence of social interactions through the inimitable qualities of designs stamped into vessel surfaces. Archaeologists have proffered various hypotheses to explain movement of ceramic vessels or the carved wooden paddles used in the manufacture of these vessels. This study tests these hypotheses and indicates that nonlocal vessels, particularly complicated stamped ones, were deposited almost exclusively in mortuary contexts, a pattern that requires new explanations for the role of pottery in social interactions. These data are being integrated with a larger project that aims to reveal the social processes that were tied to the manufacture, use, and distribution of pottery.     

Identification of Pottery‐Forming Techniques using Quantitative Analysis of the Orientation of Inclusions and Voids in Thin Sections

The relationship between forming techniques and orientation of the components of ceramic materials in the context of pottery technology has long been recognized and used for identification of the techniques employed to create archaeological ceramics. The alignment of inclusions is usually characterized by qualitative categories or ordinal scales. This paper evaluates the potential of quantitative orientation analysis for identification of pottery‐forming techniques. A collection of experimental pottery formed using five forming techniques and combined techniques was analysed. The forming techniques were characterized by the intervals of the mean direction and the circular standard deviations of the orientation of the major axes of the ellipses equivalent to the objects representing random sections of inclusions and voids. The most informative criteria for the identification of pottery techniques are the circular standard deviation of the inclusion/void orientations in the core area of the vessel wall in a perpendicular thin section and the mean direction in a tangential section.     

Ceramic Production and Dietary Changes at Juffure,Gambia

This paper explores the connection between ceramic production and dietary changes immediately before, during, and through the decline of the Atlantic trade at Juffure on the Gambia River. The height of the Atlantic trade in the eighteenth century was a period of increased ceramic production and technical experimentation. Simultaneously, there is increase in the diversity of consumption evident in the faunal and botanical remains recovered. This diversity, in both ceramic manufacture and diet, all but disappears with the decline of the Atlantic trade on the river. It is argued that the greater variety observed in ceramic manufacture during the height of the Atlantic trade is related to social practices of display associated with food. This is accomplished through a comparison of everyday and special events composed of displays of food and wealth across ethnic boundaries. These are indicative of different traditions of consumption and discard rather than signaling ethnic differentiation.     

Imperial Expansion, Ethnic Change, and Ceramic Traditions in The Southern Chad Basin: A Terminal Nineteenth-Century Pottery Assemblage from Dikwa, Borno State, Nigeria

In the course of an archaeological project in the southern Chad Basin of Nigeria, excavations were conducted at several deeply stratified mound sites that date from the Late Neolithic to the Late Iron Age. As a way to complement the ceramic sequence obtained so far and to link it with today's pottery tradition, a small excavation was conducted at a site that dates to the turn of the nineteenth to the twentieth century A.D. A pottery assemblage was discovered that shows obvious links to today's tradition but notable breaks with those of the nineteenth century and earlier. This break in decoration style and technique is interpreted as an archaeologically visible expression of changing ethnic identity. This ethnic change and the associated spread of the ceramic tradition can be linked with the expansion of the sphere of power of the Kanem-Borno Empire into the area south of Lake Chad after the sixteenth century A.D.     

Statistical Analysis of Spatial Distribution of Ceramics from Late Bronze Age/Early Iron Age Sites in Southwestern Siberia

Results of the statistical analysis of spatial distribution of ceramics at Chicha-1, Zavialovo-5, and Linevo-1 indicate ethnic heterogeneity and the presence of native and immigrant ceramic traditions within separate sites and even within single dwellings. The arrangement of pottery inside residence structures follows certain regularities. All residents, however, were apparently involved in the same manufacture.     

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.     

Selected with care? – the technology of crucibles in late prehistoric Scotland. A petrographic and chemical assessment

Prehistoric crucibles and other metalworking ceramics are often described as highly specialised tools made from refractory materials, but little is known about regional trajectories and individual material developments. Hence, further analyses of materials from less studied regions are needed. The current study investigates the technological development of crucibles from late prehistoric Scotland and its relation to technological choices and specialisation. The examination, using ceramic petrography and Energy Dispersive X-Ray Spectroscopy, focuses on the selection of clays and additives for the manufacture of crucibles in contrast to moulds and pottery. It is demonstrated that the production of crucibles in the late prehistoric period predominantly used local resources. Late Bronze Age crucibles have a close relationship with other types of technical and domestic ceramics, while materials in the Iron Age indicate an increased material specialisation for the preparation of particular fabrics. This development is seen across Scotland and echoes trends seen in other areas of Europe, emphasising the role and importance of metallurgical and technological networks.     

Using portable energy dispersive X-ray fluorescence (EDXRF) analysis for on-site study of ceramic sherds at El Hibeh,Egypt

As part of its geoarchaeological research program, the El Hibeh Project of the University of California, Berkeley field-tested at the site of El Hibeh, northern Middle Egypt, the utility of a portable EDXRF unit for obtaining geochemical analyses of pottery suitable for provenance and other ceramic classification studies. When the geochemical ceramic data from the field test are combined with basic petrographic analysis for the pottery sample set, compelling results are generated. In particular, a triangular scattergram using elemental iron, strontium and rubidium data, in parts per million, provides excellent temporal and spatial separation of ceramic fabrics type, origin and date. The geochemical behavior of iron, strontium and rubidium is discussed in relation to geological source materials utilized for pottery manufacture.     

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.     

Fragments of a Hanging-Bowl from Bekesbourne,Kent, and Some Ornamental Problems

ENGLAND IN THE 9TH CENTURY witnessed a revolution in pottery production. For the first time since the Roman period, pottery was wheel-thrown and produced on a near industrial scale. Research into this ceramic revolution has focused on chronology and, in particular, whether the technology was introduced before Scandinavian settlement. Yet, little attention has been paid to technological choices made by the potters or how these choices were influenced by wider societal changes. This paper takes a holistic approach to production, employing a range of analytical techniques to reveal the production sequence followed by potters working at one of the new industries — Torksey (Lincolnshire). With new insights into raw material choices, processing procedures, vessel forming practices and firing regimes, the paper challenges long-standing assumptions about manufacturing practice and the spread of the potters’ wheel. Opening a window into the mind of the potter, this article offers a greater understanding of the mechanisms that facilitated the diffusion and ultimate success of this new technology.     

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.     

A late fourth‐ to early third‐millennium grave from Bahrain,c.3100–2600 BC

This article presents an exceptional burial that was excavated in 1986 by the National Museum of Bahrain. The presence of two ‘Jemdat Nasr’ style ceramic vessels in the grave makes it a unique testimony of occupation on Bahrain Island in the late fourth to mid‐third millennium BC. A local cooking vessel also uncovered from the grave represents the earliest local pottery production so far uncovered in Bahrain.     

Pottery Styles during the Early Jomon Period: Geochemical Perspectives on the Moroiso and Ukishima Pottery Styles

Energy‐dispersive X‐ray fluorescence (EDXRF) was used to determine the minor and trace element chemistry of 92 Early Jomon pottery sherds. The sherds came from four contemporary sites in the Kanto region and belong to either the Moroiso or Ukishima style of pottery. Principal components analysis (PCA) and discriminant analysis indicate that there are four major groups in the data set, which correspond to site location. Furthermore, for sites having both Moroiso and Ukishima pottery, the statistical tests indicate that both styles of pottery were made from the same or geochemically similar raw materials. This suggests that both styles were probably made at the same site, and indicates that if the different pottery styles are reflecting ethnic identity, then intermarriage between ethnic groups is occurring. Alternatively, the pottery styles could be reflecting some sort of social interaction between groups.     

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 PRODUCTION,PROVENANCE AND USE—A REVIEW*

The contribution of the physical sciences to the reconstruction of the production technology (i.e., processing of raw materials, forming, surface treatments and firing methods) for earthenwares, stonewares, porcelains and stonepaste bodies are summarized. The organization of production and the reasons for technological choice are considered. Provenance studies based on both chemical analysis and thin‐section petrography are discussed, with the investigation of Minoan and Mycenaean pottery being taken as the case study. The approaches to determining how pottery vessels were used in antiquity are outlined. Finally, future developments in ceramic studies are briefly considered.     

Ceramic Traditions and Cultural Identities: West‐Central France during the Late Neolithic II Period (c.3400–2900 cal. BC)

Pottery is generally used as the main basis for characterizing Neolithic cultural identities: archaeologists tend to define groups and cultures in time and space on the basis of typological classification. This paper proposes a different approach to the study of pottery that takes into account the various steps of the chaîne opératoire of manufacture, particularly the methods used to form and finish the pots, in order to characterize the cultural landscape of the Late Neolithic II period in west‐central France (3400?2900 BC). This cultural landscape has hitherto been poorly defined and subject to endless debate since the 1950s, largely because the pottery is fairly homogeneous in shape and is mostly undecorated. The technological study presented here, based on the examination of 23 ceramic assemblages and focusing on a variety of stages in the chaîne opératoire, has allowed the definition of three technical traditions. The main characteristics and diagnostic features of these traditions are outlined below, together with their interrelationships.     

Pottery politics: Late Classic Maya palace production at Motul de San José, Petén,Guatemala

Archeologists often rely heavily on stone monuments, architecture, settlement patterns, and written texts to reconstruct ancient political systems. In this paper we focus on the role of polychrome pottery as both a reflection of and critical component in the production of power relations. We present rare direct evidence of polychrome pottery production recovered from the Maya site of Motul de San José, the presumed Late Classic (ca. 600–900 AD) capital of the epigraphically-recognized Ik’ polity. Our contextual analysis of production debris and tools complement on-going polychrome vessel style and chemical analyses of Ik’ Style polychrome vessels to suggest that Motul de San José’s royal court was an important center in the manufacture of Ik’ Style polychrome pottery. These elaborate vessels indexed the political history, power, and networks of the Ik’ polity. By combining archeological, iconographic, and epigraphic data of polychrome pottery, we shed light on Motul de San José’s internal political-economic dynamics as well as its macro-political alliances and tensions with other polities.

An Investigation of Ceramic Forming Method Using Reverse Engineering Techniques: The Case of Oinochoai from Dion, Macedonia, Greece

A method for investigating the forming technique of ancient ceramic vessels is presented. The recording, analysis, and comparison of the vessels' metrical properties by means of computer tomography, three-dimensional laser scanning, and solid-modeling software enables the identification of the applied manufacturing methods. A finite elements method-based simulation of the developed deformations during the vessels' manufacture offers significant insight into the applied shaping procedures. By making possible the exact recording of both the internal and external form of the vessels as well as the simulation of the forming procedure, the method represents a marked improvement to hitherto applied methods based on radiography. The method is applied on two early iron age ceramic jugs (oinochoai) found as offerings in tombs in excavations in Dion, Greece.
