Revisiting the Exploitable Threshold Model: 14th century resource procurement and landscape dynamics on Perry Mesa,Arizona

Abstract

This study presents a revision of Dean E. Arnold’s (1985, 1993) Exploitable Threshold Model, which attempts to explain the selection of raw materials for pottery production. Arnold’s model posits that potters’ preferences for materials are largely determined by the linear distance to individual resources. We argue, however, that potters’ choices are, at least in part, determined by spatial relationships among the necessary resources rather than the distances to them. This study of 14th century pottery production on Perry Mesa, Arizona demonstrates that potters selected materials based on the co-occurrence of readily available sources of temper, clay, and fuel. Lack of water and fuel sources on the mesa top compelled local residents to eschew the use of readily available basaltic sands to temper their plainware pottery. Instead, Perry Mesa potters selected granitic sands from the river valley nearly 300 vertical meters below their settlements.     

Variability of Ceramic Production and Consumption on the Greek Mainland During the Middle Stages of the Late Bronze Age: The Waterpots from the Menelaion,Sparta

The article examines pottery groups manufactured in non‐Mycenaean traditions from the site of the Menelaion in Laconia (southern Peloponnese, Greece) during the middle stages of the Late Bronze Age. Pottery traditions are first defined using macroscopic study of surface and break features. Two distinct handmade traditions, and another one employing the wheel but with some links to traditional handmade pottery manufactured on the island of Aegina, were recognized and subjected to petrographic analysis. Its results confirmed that potters’ choices regarding clay preparation were different in the case of each identified tradition, being most distinct for the largest group of handmade undecorated water jars. The study highlights survival of pottery traditions with roots in the Middle Helladic period well into the Late Bronze Age, a fact that has not received appropriate attention in the scholarly discourse. It captures the very last stage of their existence, as just a few decades later the production and consumption are entirely dominated by Mycenaean pottery.     

古代指纹与陶工年龄分析——以二里头遗址出土陶器资料为例

古代陶器上常常保留着当时陶工的指纹痕迹,而现代指纹学的研究成果表明,指纹形态与年龄阶段存在着一定的对应关系。故本文通过引入现代指纹学的研究成果,对二里头遗址出土陶器上的指纹痕迹进行采集、观察、测量,试图在此基础上识别与探讨当时陶器生产者的年龄状况以及可能存在的"未成年"陶工。本文的分析结果显示,二里头遗址二里头时期陶器生产者的年龄构成可能较为多样,而且当时的"未成年人"很可能已经参与到陶器生产过程中,并且根据目前的指纹标本推测,他们或许主要从事辅助性工作。     

A case for lead-glaze experimentation by late eighteenth-century Catawba using portable X-ray Fluorescence (pXRF)

ABSTRACT

Recent research has demonstrated that Catawba ceramic practices changed abruptly and dramatically after 1759 following a devastating smallpox epidemic and subsequent community relocation. Pottery from the historically documented Catawba town of Old Town and others indicate potters adopted new techniques and styles as they adjusted to new economic and social conditions, including copying European vessel forms, experimenting with new ceramic paste recipes, and utilizing new decorative motifs. The identification of four lead-glazed sherds on otherwise Catawba-looking pale-bodied paste raises the possibility that Catawba potters may have also experimented with lead glazing. This paper presents the results of an elemental analysis of nearly 70 ceramic samples using pXRF and multivariate statistical techniques to identify patterns of production within pale-bodied colonowares. The results indicate that the glazed pottery fragments were made with elementally similar clay used by Catawbas in the Twelvemile Creek locality. I argue that in addition to modifying nearly every aspect of their ceramic repertoire, at least one Catawba potter experimented with lead glazing, providing further insights into the emergent Catawba pottery trade.     

Testing technological practices: neutron activation analysis of neolithic ceramics from Valencia,Spain

Using instrumental neutron activation analysis (INAA) of prehistoric pottery, daub, and modern clay samples from Valencia, Spain, we tested expectations on changes in raw material use with socio-economic shifts during the Neolithic (ca. 5600–2800 BC). Elemental analysis identified three distinctive clay source groups used by Neolithic potters. Contrary to expectations, a shift in raw material use was identified between the Early and Middle Neolithic despite general similarities in technological practices. In the Late Neolithic, pottery production became more specialized, but potters used the same range of clay sources documented earlier. This study illustrates the utility of INAA for testing hypotheses of prehistoric craft production.     

Notice of the Annual Meeting,at Norwich

Excavations took place in 1969, in advance of housing development, on the site of a fourth-century Roman pottery workshop, two adjacent kilns, a well, a large pit and two burials. The workshop contained internal features linked with pottery production, including possible emplacements for potters' wheels. Two kilns, each constructed differently, were producing grey and colour-coated wares. A large pit was used for rubbish. A well, square in plan, was associated with the workshop and must have provided water for the potters. Of particular interest was a complete millstone, which appears to have been used as a flywheel fixed to a potter's wheel. Pottery production at the site may have continued into the early part of the fifth century and as such is one of the last known production centres of the Roman Nene valley pottery industry. The site is significant in that it probably represents a near complete and typical industrial pottery production unit within a major pottery production area of the province and represents an important aspect of the late Roman economy.     

Non-destructive fabric analysis of prehistoric pottery using high-resolution X-ray microtomography: a pilot study on the late Mesolithic to Neolithic site Hamburg-Boberg

The characterisation of prehistoric pottery fragments presents a quite complex task. In provenance studies, petrographic and chemical analyses of the ceramic materials are employed to investigate potential production areas in respect to the geolocial background. Moreover, also the production technology of the firing process, as well as the forming techniques used by the prehistoric potters are of great interest. Their investigation is most often accompanied by a destructive preparation of the samples. In this paper, we want to present high-resolution X-ray microtomography (μ-CT), a non-destructive and non-invasive method, as a supplementary research tool in the study of prehistoric pottery.     

Chemical and Petrographic Analysis of Pre‐Hispanic Pottery from the Southern Abaucán Valley,Catamarca, Argentina

Neutron activation (NAA) and petrographic analyses were carried out on Late and Inca Period pottery from 15 archaeological sites and several clay samples in the southern Abaucán Valley, Catamarca, Argentina. The results from the NAA and petrographic analyses provide new data concerning local versus non‐local pottery production and vessel exchange for these two pre‐Hispanic cultural periods. The chemical data demonstrate the use of different clay sources over time until the Inca appearance in the region, when a more structured and controlled production is observed. Petrographic analyses show a similar change in the ceramic paste recipes used by ancient potters.     

Meaning in the making: The potter’s wheel at Phylakopi,Melos (Greece)

It is now commonly accepted that technology is, to its very core, a social product through which we can explore cultural choices. This cultural dimension of technology will be examined with reference to the introduction and use of the potter’s wheel at Phylakopi on Melos (Greece) during the Late Bronze Age. At this site, the co-existence of two different manufacturing techniques was so deeply embedded that, despite the presence of hybrid vessels, many aspects of the pottery production had become linked to either a local (hand-built) or Minoanising (wheel-thrown) tradition. It will be argued that the traditional hand-building technique was associated with individual and rooted facets of the Melian identity (such as kinship, social class, or gender). Reasons for the initial stimulus for adoption of the potter’s wheel are considered to lie in its potential for competitive social practice through association with exotic, symbolically laden technologies, craft products and consumption rituals. The gradual application of the technology to ever more complex vessels, on the other hand, corresponds to the apprenticeship sequence outlined by Roux and Corbetta and may indicate an incomplete learning process or a certain lack of practice opportunities among local potters.     

Whose development? The dilemma of rural artisan women in southwestern Ethiopia

This article examines the socio-economic situation of pottery-making households in southwestern Ethiopia. In this region, pottery production lies exclusively within the women's domain, and taboos and restrictions surrounding the practice prohibit male involvement. Potters are marginalized, banned from land ownership and sometimes form endogamous castes. Ethiopian development policy and the perception of indigenous pottery technology as ‘unproductive’ have threatened the continuity of the tradition and the livelihood of rural potters. Meanwhile, foreign-made plastic and enamel products are gradually replacing indigenous pottery.     

POTS, HOUSES AND METAL: TECHNOLOGICAL RELATIONS AT THE BRONZE AGE TELL AT SZÁZHALOMBATTA, HUNGARY

Summary.   At the Bronze Age tell of Százhalombatta, Hungary, techniques used for making pottery echo those used in other media. Pottery and architecture have a close relationship. Not only were both made of clay, but methods of making pots echo those used for building. Similarly, pottery and metalwork share common themes and technologies for working with clay and bronze. Since choices made by potters are not solely confined to the environment, raw materials and tools, but are also socially and culturally defined, by implication the transfer of know-how must be situated within social networks between people. This paper considers how the identification of technical relationships between different media at Százhalombatta can be used to explore social relations in Bronze Age society, thereby suggesting relationships that work on both technical and social levels.     

CLAY RESOURCES AND TECHNICAL CHOICES FOR NEOLITHIC POTTERY (CHALAIN,JURA, FRANCE): CHEMICAL,MINERALOGICAL AND GRAIN‐SIZE ANALYSES*

Many authors have considered pottery manufacturing constraints and sociocultural elements as factors in change in past civilizations over time. The main issue of this research is to better understand the reasons for changes, or choices, in pottery raw materials. The very precise and detailed stratigraphy and cultural succession of occupations is based on dendrochronological data from the lake‐dwelling sites of Chalain (Jura, France). Petrographic, palaeontological and chemical analyses were used to determine the nature and origins of the raw materials used by the Neolithic potters. Stratigraphy and dendrochronological data were used to reconstruct in detail the evolution dynamics of fabric changes. Several raw material sources were identified for many of the pottery groups. Each of them was sampled for qualitative experimental tests of pottery forming. The experimental results show a high variability between the sediments tested. This variability was quantitatively estimated by XRF, XRD, the Rietveld method, calcium carbonate quantification and laser grain‐size analyses of matrices, indirect measures of plasticity. These analytical results allow a better understanding of the differences observed in the experimental tests. On the basis of these experimental and analytical results, changing parameters such as pottery manufacturing constraints, mineralogical characteristics of raw materials and sociocultural factors are considered. In conclusion, all the social and technical parameters, in each archaeological context, must be taken into account for a better understanding of the changes occurring throughout the chronological sequence.     

LEAD ISOTOPE ANALYSES OF ISLAMIC POTTERY GLAZES FROM FUSTAT,EGYPT*

Lead isotope analyses have been undertaken on a group of Islamic lead‐glazed pottery artefacts from Fustat, Egypt, spanning the period from the eighth to the 14th century ad , that had previously been the subject of a comprehensive typological, chronological, petrographic and technological study. Comparison of the lead isotope ratios for the glazes with those for lead ores from Egypt, Iran, Tunisia, Anatolia, Greece, Sardinia and Spain provided information on the possible sources of the lead used in the production of the glazes. The results show that the lead used in glaze production by the Islamic potters at Fustat was most probably obtained from distant ore sources in Iran or Tunisia, Sardinia, Spain and the Taurus Mountains. Different ore sources were favoured in different periods and, to a limited extent, for different types of pottery, but at no time did the Fustat potters use the potentially more accessible Egyptian ore sources.     

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.     

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.     

The process,location, and history of Hohokam Buff ware production: some experimental and analytical results

A distinctive red-on-buff pottery, found throughout central and southern Arizona, is a hallmark of prehistoric Hohokam culture. To manufacture it, Hohokam potters used a complicated recipe and controls for firing to chemically manipulate their clay and produce a light-colored fabric on which to paint their red designs. In this study, firing experiments and ceramic analysis are used in conjunction with excavation evidence to evaluate competing ideas about the buff ware manufacturing process, investigate where the pots were made, and model the developmental history of red-on-buff production.     

Pottery production on Rishiri Island,Japan: perspectives from X‐ray fluorescence studies

Energy‐dispersive X‐ray fluorescence (EDXRF) was used to determine the minor and trace element composition of 54 sherds of pottery dating from the Final Jomon to Okhotsk periods. The majority of the sherds came from Rishiri Island, Japan. Principal component (PC) scores were calculated using the log transformed concentration values, and groups were sought in the PC scores using kernel density estimates (KDEs). Two main groups were found in the data; linear and quadratic discriminant analysis classified both groups successfully. Significant differences in the concentrations of Cu, Fe, K, Nb, Pb, Rb, Th and Zr were found to exist between the two groups. The lack of correspondence between chronological ware types and geochemical groups implies that the same raw materials and paste recipes were in use during the Epi‐Jomon and Okhotsk eras on Rishiri Island. One possiblity is that the Epi‐Jomon and Okhotsk potters used the same clays and tempers, since no other alternatives were available. Alternatively, the Okhotsk potters could have adopted the same paste recipes as the Epi‐Jomon potters, or the Okhotsk pottery tradition could be descended from the Epi‐Jomon pottery tradition.     

TESTING ASSUMPTIONS OF NEUTRON ACTIVATION ANALYSIS: COMMUNITIES,WORKSHOPS AND PASTE PREPARATION IN YUCATAN,MEXICO*

Contemporary pottery and raw materials (N= 170) from three workshops in Ticul, Yucatán, were analysed by neutron activation to test the hypothesis that individual workshops that used their own clay sources could be identified by their pottery. Although the data failed to confirm the hypothesis, the results reinforced previous conclusions about the relationship of local communities of potters to the chemical patterning of pottery made in these communities.     

Pottery Production, Distribution, and Consumption—The Contribution of the Physical Sciences

The study of the life cycle of pottery, from the selection of raw materials and the production stage through distribution and use to ultimate discard, can make a valuable contribution to archaeological research. The aim of the present paper is to provide a summary and critical assessment of the particular contribution of the physical sciences to the reconstruction and interpretation of this life cycle, in large part through the presentation of selected case studies. The topics covered include the reconstruction of the technology used in pottery production, through a combination of microscopy, radiography, and chemical analysis; the investigation of the extent of craft specialization and the organization of pottery production; the reconstruction of pottery distribution from its production center, using thin-section petrography and chemical analysis, and the interpretation of these data in terms of exchange and trade; the reconstruction of the consumption stage or uses to which pottery was put, from the study of surface wear, organic residues, and performance characteristics; and a discussion of the reasons for the introduction of pottery and for the different technological choices made in pottery production. Throughout, the importance of considering the overall environmental, technological, economic, sociopolitical, cultural–ideological and historical context in which the pottery was produced, distributed, and consumed is emphasized. The paper is concerned, almost-exclusively, with unglazed earthenware spanning prehistory through to circa 1500 AD.     

DUNG BY PREFERENCE: THE CHOICE OF FUEL AS AN EXAMPLE OF HOW ANDEAN POTTERY PRODUCTION IS EMBEDDED WITHIN WIDER TECHNICAL,SOCIAL, AND ECONOMIC PRACTICES*

A discussion of how Andean potters acquire and use their fuels is used to demonstrate the ‘embedded’nature of ceramic technology. The most common choice of fuel in the highlands of Peru and Bolivia is animal dung (mainly cow, sheep, and llama). This technological choice is related to wider social and economic practices (particularly in relation to animal husbandry) which has further repercussions that affect other technologies (such as agriculture practices). Such a succession of interrelated activities is not unique to pottery; it is fundamental to all technologies and should be considered within archaeological analysis.
