Ceramic Technology and Social Boundaries: Cultural Practices in Kalinga Clay Selection and Use

This study examines cultural sources of variation in ceramic compositional patterning in two pottery-making villages of the highland Philippines. In Dalupa, many potters are part-time specialists whereas in Dangtalan, women make pottery less frequently. Previous studies show that both pottery form and decoration correspond well with Kalinga social boundaries, but how do morphological and decorative patterning relate to compositional variability? Although researchers have made substantial advances in our understanding of natural and postdepositional sources of compositional variability, little is known about behavioral factors that affect chemical and mineralogical compositional patterning. This study examines cultural practices of clay selection and use in an ethnographic setting, and undertakes technical analyses to assess the relationship between behavior and material culture patterning. Our study identified paste differences between the clays and fired ceramics from Dangtalan and those from Dalupa. Findings from our compositional research thus parallel earlier morphological and stylistic studies, and illustrate multivariate differences in ceramics from these two Kalinga communities. This ethnoarchaeological and analytical project contributes, therefore, to understanding objective parameters within a behavioral context. It also provides an example of how a combined characterization approach, using chemical and petrographic techniques, can yield insights on intraregional variation at a finer scale of resolution than is often attempted.     

Forming and Shaping Pottery Boundaries in Contemporary South-Eastern Botswana

In southern African archaeology, the equation of pottery styles with archaeological ‘cultures’ and their attribution to the antecedents of contemporary ethnic groups has been a common practice for a long time. Ethnoarchaeological studies from other parts of Africa and beyond have shown that the matter is complex and that stylistic and technological boundaries in ceramic distributions can reflect different kinds of social boundaries under different circumstances. To expand on these findings and make them locally relevant, a large-scale ethnoarchaeological study of 41 potters in south-eastern Botswana aims for a better understanding of ceramic technological style and boundary relations. Here, we present and explain only the results concerning the boundaries in the forming and shaping stage of ceramic vessel manufacture. We conclude that learning networks explain the visible boundaries in the technological style of forming and shaping pots in south-eastern Botswana today; language and ethnic affiliation do not. Boundaries in the other stages in the operational sequence of pottery manufacture, such as clay sourcing and preparation, vessel surface treatment and decoration, firing and finishing, will be presented in a series of further publications.     

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.     

Breaking down ceramic variation: Testing models of white mountain redware design style development

Design styles on White Mountain Redware pottery from the American Southwest are analyzed, drawing on ethnoarchaeological work conducted among the Kalinga of northern Luzon, the Philippines, to establish a strong relationship between distinct social groups and ceramic decoration. From this base, regional production zones are identified for several White Mountain Redware design styles in eastern Arizona and western New Mexico. In addition, the temporal and spatial distribution of these styles is compared to expectations generated by three models of design style development, none of which is completely acceptable. An alternative explanation is proposed in which White Mountain Redware stylistic change is linked to the development of (1) symbolic association between design styles and regions or communities of production, (2) increasing exchange of pottery over longer distances and in larger numbers, and (3) part-time specialization in pottery production. These trends, in turn, are a likely consequence of population increase and aggregation into larger puebloan communities in which contradictory processes, such as economic interdependence and competitive interaction between settlements, may have emerged to disrupt the late prehistoric evolutionary tendency towards greater social complexity.     

The history of method and theory in the study of prehistoric puebloan pottery style in the American Southwest

The history of Americanist archaeology can be profitably approached through an examination of ceramic design studies in the puebloan region of the American Southwest. An intellectual tradition is represented throughout these studies, grounded in the assumption that ceramic design variation can be reflected, among other things, in prehistoric social groupings. Within this tradition, a number of differences in method, theory, and application can be distinguished, including (1) the classificatory systems employed, (2) the spatial and temporal scales at which ceramic design variation was studied, and (3) the potential functional role of stylistic attributes on pottery. The debates, both intellectual and social, surrounding the development of method and theory in the New Archaeology are clarified by this historical review, as are the transitions to Culture History and from the New Archaeology in the American Southwest.     

Symbols of Cultural Identity: A Case Study from Tanzania

Cultural expressions and their contexts of use among two groups of Maconde form a basis for a discussion of cultural reproduction and the fluidity of ethnic boundaries. The material presented here is based on ethnoarchaeological fieldwork in Tanzania and Mozambique. Two groups, one based in Tanzania and the other in Mozambique, both identify themselves as one group, although they use and display material culture quite differently. The arguments in the paper are concerned with understanding the highly dynamic character of ethnicity in these East African societies and an attempt to look at shifting ethnic boundaries among the groups in the Rovuma Basin, in particular, over the last centuries. Here symbols of cultural identity have been manipulated and reintroduced into new contexts, as cultures change and groups adjust to their social environment.     

Identifying pottery clay from rice fields: an example from southern Luzon,the Philippines

The general type of clay used by potters can often be identified from attributes of the finished ceramic vessel or sherd. This information is important for compositional and sourcing studies and may also shed light on the variables influencing clay choice such as social, economic, and landscape use patterns. Rice paddies are one type of clay source that are readily identifiable in archaeological ceramics. This paper describes rice paddy clays gathered during ethnoarchaeological studies of traditional potters in Paradijon, southern Luzon, the Philippines. We analyze the effects of clay processing and vessel manufacture on these clays and find that the most diagnostic attribute of paddy soils, the iron oxide mottling, is retained in finished vessels.     

Gendered Taskscapes: Food,Farming, and Craft Production in Banda,Ghana in the Eighteenth to Twenty-first Centuries

This article blends insights from gender, technology, and development studies with Ingold’s concept of taskscape to examine the interrelated nature of farming, food, and craft manufacture practices in Banda, Ghana during the last three centuries. We begin by comparing two ethnoarchaeological studies that were conducted separately by the authors, one that focused on food, and the other on ceramic production, preparation, and consumption. We use these data to analyze gendered taskscapes and how they have changed in recent decades with the introduction of new technologies and major economic and environmental shifts. Building on such insights, we analyze how taskscapes shifted in earlier centuries in Banda through archaeological remains of food and craft practice at the eighteenth- to twentieth-century site of Makala Kataa. Craft production cannot be fully understood without reference to food production, preparation, and consumption; thus, viewing these practices as interrelated tasks in a gendered taskscape yields insight into the rhythms of everyday life and highlights women’s often undervalued skills.     

Culinary Crafts and Foods in Southwestern Ethiopia: An Ethnoarchaeological Study of Gamo Groundstones and Pottery

Few ethnoarchaeological studies have combined the production and use of groundstones and pottery as indicators of household variation in subsistence and socioeconomics. This ethnoarchaeological study explores how the Gamo people who live in southwestern Ethiopia interact with their culinary tools of pottery and groundstones. One of the unique cultural features of the Gamo is their strict caste system, which forces artisans such as potters and groundstone makers into a full-time specialization. This paper uses a chaîne opératoire analysis regarding groundstone and pottery production and then addresses their use by drawing from household studies from three Gamo communities. The analysis discusses the role that social hierarchy can have on cooking and craft variation within households. Thus, these artisans bring to life crafts that give the Gamo tools to create their daily subsistence, and these tools and foods allow us to explore two key archaeological issues: subsistence and socioeconomic variation of people’s households.     

Recent ceramic analysis: 1. Function,style, and origins

The recent literature on ceramic analysis, which has grown dramatically over the last 8 years, is reviewed in two articles. In this first article attention focuses on studies of function and use, stylistic analyses, and pottery origins. Functional analysis has been the most rapidly expanding segment of the field, particularly experimental, ethnoarchaeological, and residue analysis approaches. Stylistic analyses seem to be in a lull, following increasing dissatisfaction with information theory approaches. Questions of pottery origins are enjoying renewed interest and are briefly surveyed here. The second of the two articles will survey compositional investigations, pottery production, and approaches to ceramic theory. Both reviews close with observations on current directions in ceramic studies.     

Ceramic style analysis in archaeology and ethnoarchaeology: Bridging the analytical gap

A refitting study with a sample of sherds from Broken K Pueblo indicates that at least some of the “patterning” in the assemblage identified by Hill (1970, Anthropological Papers of the University of Arizona 18) results from unrecognized whole vessels and large conjoinable sherds. It is argued that contemporary stylistic analyses are based on many of the same analytical methods employed in the Broken K study and that research findings of ethnoarchaeology are rarely applied in the analysis of prehistoric ceramics. Despite archaeologists' increasing awareness of formation processes, spurred by ethnoarchaeological research, analytic methods that identify and take into account the effects of these processes on archaeological ceramic assemblages are underdeveloped. Suggestions are offered to resolve this problem, for both archaeological and ethnoarchaeological ceramic analysis, that may permit archaeologists to discover in prehistoric assemblages the same types of relationships identified in systemic assemblages.     

Ethnoarchaeology and the Organization of Lithic Technology

Although the modern production and use of stone tools is rare, ethnoarchaeological research on this subject has provided important perspectives on methodological approaches to archaeological lithic analysis. Recent ethnoarchaeological research on lithics frequently takes the form of “cautionary tales,” warning against the primacy of functional variables most commonly invoked by lithic analysts. I argue that lithic ethnoarchaeology would benefit from a comparative organizational framework for explaining variation in patterns of stone tool use that takes into account the predictability and redundancy of the location and timing of technological activities. Understanding the underlying causes of modern patterns of stone tool use, in turn, offers a framework for exploring sources of lithic technological variation in the archaeological record. I also argue that technological analytical perspectives, such as the cha?ne opératoire and sequence of reduction approaches, can benefit from the insights gained through lithic ethnoarchaeological research, helping us define important analytical concepts and identify appropriate units of analysis.     

Measuring reduction in stone tools: an ethnoarchaeological study of Gamo hidescrapers from Ethiopia

Stone tools were knapped, not built. This truism means that tools were reduced from larger pieces in the production process. But many tools were further reduced in use, to repair damage or as edges dulled. Reduction reduced size (trivially), but also changed the proportions among tools' elements or dimensions. Such allometric variation (change in proportion as a function of change in size) is useful to estimate the degree of reduction that tools experienced. Reduction itself is a measure of curation, a theoretical concept of great interest in lithic studies and Paleolithic archaeology. To determine the reduction that archaeological tools experienced, we must compare their size and proportions at first use to the same properties at discard that we directly measure. By now many size estimates can be made from discarded tools. Some are experimentally tested but few are validated using direct ethnoarchaeological controls. We validate two allometric reduction measures—ratios of plan area to thickness and of an estimate of original to discarded volume—against direct measures of use and reduction in ethnographic Gamo hidescrapers from Ethiopia.     

Compositional characterization of Etruscan earthen architecture and ceramic production

This study presents the results of new research into Etruscan technology for earthen architecture as well as ceramic production in the upper Tiber Valley in central Italy, using as a case study the Etruscan settlement of Col di Marzo (Perugia). It determines the compositional differences of the raw material employed as building material and for ceramic production by X-ray powder diffraction (XRD), thermogravimetric analysis and differential thermal analysis (TG-DTG), Fourier-transform infrared analysis (FTIR) and geotechnical analyses. The research also advances the knowledge of ceramic manufacturing technology, with a focus on impasto production, at Col di Marzo between the fifth and mid-third centuries bce and the surrounding territory on the left bank of the River Tiber. The compositional analysis of building material compared with the ceramics provides answers to questions related to their sourcing and deepens the understanding of the exploitation of natural resources .     

Changing perceptions of West Africa's past: Archaeological research since 1988

Archaeological research since 1988 in West Africa has focused almost exclusively on the period since 10,000 B.P. Significant advances have been made in our understanding of the Late Stone Age in the Sahara and Savanna zones, the advent of metallurgy and subsequent changes in metal technology, and the comparative trajectories of complex societies in different regions. Increasingly, data are being recovered that fail to conform to earlier Eurocentric assumptions emphasizing linear, progressive change through a series of evolutionary ages and stages. The search for new, more appropriate models for interpreting West Africa's past has infused the discipline with great theoretical vitality. Both ethnoarchaeological studies and traditional archaeological research programs in West Africa are contributing substantially to the articulation of new theoretical frameworks for African archaeology and potentially for the discipline as a whole.     

Ancient beer and modern brewers: Ethnoarchaeological observations of chicha production in two regions of the North Coast of Peru

Archaeological studies of alcohol have tended to focus on consumption while production, particularly of beer, has been more difficult to recognize and interpret. The ethnoarchaeological study of modern maize beer or chicha production on Peru’s north coast provides information on (1) production steps and their material correlates, (2) labor and raw material inputs at different scales and possible labor bottlenecks, and (3) variation in technology and organization that is linked to contexts of consumption and cultural differences through time across the Andes. Because of this variation, the ethnoarchaeological observations reported here should not be directly projected onto the past, but rather should serve as points of comparison with the archaeological record.     

Marginalized Potters and Ceramic Compositional Groups: Neutron Activation Analysis of Contemporary Pottery from Tigray,Northern Highland Ethiopia

The study presents the results of neutron activation analysis (NAA) of contemporary pottery from Tigray Regional State, northern highland Ethiopia. This is the first regional-scale study of ceramic composition of Tigray’s pottery and is part of an ethnoarchaeological study of the material and social contexts of pottery production and consumption in Tigray’s Eastern (Misraqawi), Central (Mehakelegnaw), and North-western (Semien Mi’irabawi) zones. The analysis identifies clear compositional groups with strong regional patterns, an encouraging result for the use of NAA to study Tigray’s ancient pottery trade. Significantly, the study further contributes to discussions of how mutually constituted social identities of potters and consumers affect compositional patterning in the distribution of pottery in market networks.     

Mobile Humanity: The Delocalization of Anthropological Research

Anthropological research in recent decades has become increasingly multi-sited, envisioning the local as an iteration of world-systemic processes, and following the movement of people, things and ideas across the typical boundaries of sites. This review essay examines four edited volumes concerned with such mobility and dislocation. The cultural anthropological volumes engage with the strengths and perceived weaknesses of multi-sited ethnography, the advantages of following people and themes across space, and the definition of sites by topic rather than by place. The archaeological collections move beyond typologies that have constrained archaeological investigations of movement through the study of the material practices that constituted social landscapes of mobile and settled peoples. Although the reviewed volumes offer important methodological distinctions and theoretical engagements, all four provide numerous ethnographic and ethnoarchaeological views of the delocalization of anthropological research, including claims for the utility of collaborative partnerships, the following of paths across space and time, and the reconsideration of the fixity and centrality of contemporary, historic and prehistoric places.     

Ceramic Technology of the <Emphasis Type="Italic">Asurini do Xingu,Brazil</Emphasis>: An Ethnoarchaeological Study of Artifact Variability

This article presents some of the results of ethnoarchaeological research on ceramic technology I have conducted among the Asurini do Xingu, an Amazonian indigenous population inhabiting a village in the margins of the Xingu River, Pará, Brazil. Based on collected data, presented throughout the article, I discuss the reasons behind the formal, quantitative, spatial and relational variability of the Asurini ceramic vessels. This work will demonstrate that these distinct dimensions of variability are related to the potters’ technological choices during the vessels’ production process, the ceramic teaching-learning structure, and the type, frequency, method and context of use of the same vessels. I try to make clear the different practical and symbolic aspects that may influence the production, use, reuse, storage and discard processes of the vessels. Furthermore, I compare the Asurini context with other ethnographic contexts and try to distinguish regularities that may serve as interpretative references to the study of archaeological ceramic assemblages.

Beyond the buildings: Formation processes of ancient Maya houselots and methods for the study of non-architectural space

The success of activity areas research in domestic contexts has highlighted the need for archaeologists working in the tropics to explore both indoor and outdoor spaces. The preservation of houselot boundaries at ancient Chunchucmil, Yucatán, Mexico, provides an ideal environment to explore methods for the investigation of broad spaces beyond buildings, to test ethnoarchaeological models of activity areas and refuse disposal, and to demonstrate the importance of open spaces to understanding ancient economic organization. The results of methodological experiments reported in this paper favor the use of systematic subsurface sampling (as opposed to surface collections) for characterizing specific uses of space around houses. Formation processes dictate that soil chemistry, paleoethnobotany, and other laboratory techniques should supplement excavations. Our explorations of three houselots suggest that ethnoarchaeological models of the use of space in contemporary houselots serve as successful templates for interpreting the use of space in ancient times. Post-abandonment deposition within houselots, however, can confuse these interpretations. This paper therefore reports a new ethnoarchaeological study that helps illuminate the nature of post-abandonment discard. After resolving critical issues of methodology and formation processes, this paper assesses the economic contribution of houselot activities. Given Chunchucmil’s agricultural marginality, such home economics played an important role in the subsistence needs of this urban center.
