Touchstones: some aspects of their nomenclature,petrography and provenance

Touchstones are pieces of fine-grained black stone which are used for assaying gold by comparing the colour of streaks made on the surface by alloys of known composition with the colour of the streak from an object of unknown composition. The technique has been in use since at least the 6th century BC.The petrographic aspects of the identification of touchstones are reviewed and 42 historical touchstones or museum specimens of similar looking stone are described, most of them including the results of petrographic examination.The results show that touchstones usually consist of sedimentary rock types, of which the most frequently occurring ones are tuffs, cherts and siltstones.     

Petrodatabase: an on-line database for thin section ceramic petrography

This paper presents an on-line database for the petrographic analysis of pottery and other ceramic artefacts (www.petrodatabase.com). It outlines how the system can be used by the archaeological community and anticipates its potential for greater comparability in thin section ceramic petrography.     

Modeling Late Copper Age demographics on the Great Hungarian Plain using ceramic petrography

Ceramic petrography can be an effective method for studying demographic shifts and the possibility of migration into a region. This is based on the principle that ceramic manufacturing technology is resistant to change over time, while form and decoration can change quickly even in times of demographic continuity. As such, sudden shifts in raw material preparation and methods of pottery manufacture may be indicative of the arrival of new people in a region. The manufacturing characteristics indicative of such a demographic change are observable and measurable microscopically. Petrography was used to describe and measure paste characteristics of 114 Middle Copper Age, Late Copper Age, Early Bronze Age, and Middle Bronze Age sherds from the Körös region of the Great Hungarian Plain to determine if changes in manufacturing techniques accompanied changes in ceramic form and decoration at the beginning of the Late Copper Age Baden period (ca. cal. 3500 B.C.). A comparison of the petrographic results from the cultural phases showed that little manufacturing and technology change occurred during the time period covered by the study. Migration of new people into the region is therefore not supported, and changes in ceramic form and decoration associated with the Late Copper Age occurred during an extended period of demographic continuity.     

Advances in Ceramic Ethnoarchaeology

Ceramic ethnoarchaeology has developed considerably since Kramer's (Kramer, 1985, Annual Review of Anthropology 14: 77–102) review. More sophisticated readings of social theory and analyses that consider multiple variables and levels of variability have led to better understandings of social boundaries. Perceptions of ceramic change are becoming increasingly sophisticated, thanks to more long-term projects as well as research that takes advantage of new opportunities, including historic collections and nontraditional settings. The newly developing ethnoarchaeology is contributing to general anthropological understandings of material culture and society.     

The Faragola Ceramic Collection: Ceramic Production,Consumption and Exchange in Seventh‐Century Apulia

A collection of 30 ceramic samples, 16 of coarse wares and 14 of fine painted wares, have been investigated by optical microscopy, scanning electron microscopy, inductively coupled plasma optical emission spectrometry, inductively coupled plasma mass spectrometry and neutron activation analysis. Further samples of clayey sediments, both locally outcropping and found within the settling tank, have been submitted to the same analytical techniques for comparison with the ceramic collection. The results demonstrated that local clayey sediments were used as received for the production of coarse wares. The same raw materials were sieved and/or refined by decantation for the production of fine painted wares, which, in fact, provided results that were perfectly comparable with those for the clayey raw materials found within the settling tank. The Faragola productions were distinguished from the neighbouring Apulian productions according to petrographic features (the presence of leucite‐bearing volcanic rocks and Mn‐rich wads) and their bulk chemical composition.     

Coupling lead isotope analysis and petrography to characterize fabrics of storage and trade containers from Hala Sultan Tekke (Cyprus)*

Lead isotopes, thin‐ and sherd‐section analyses are coupled on pottery‐vessel fragments excavated from the Late Bronze Age site of Hala Sultan Tekke (south‐east Cyprus) and representing fabrics used for the production of storage and trade containers. The fabrics of the sherds are first described according to general macroscopic observations. Based on the different fabrics identified, a petrographic analysis is carried out on thin sections and compared to lead isotope results on the same samples. This study shows that a specific fabric corresponds to a specific lead isotopic composition and proposes different sources for the various groups of associated sherds/fabrics. It also demonstrates the compatibility and complementarity of petrography and lead isotopes within pottery provenance study.     

Current Issues in Ceramic Ethnoarchaeology

The last decade has seen a surge in ceramic ethnoarchaeological studies worldwide, covering such important topics as ceramic production, technological change, ceramic use and distribution, and social boundaries. Some of the most exciting new Americanist research helps archaeologists refine models of ceramic production. Increasing numbers of non-Americanist studies use a technology and culture framework to examine manufacturing variability, the dynamics of cultural transmission between generations, and the articulation between ceramic technology and social boundaries. This review summarizes these recent trends, places current ethnoarchaeological research in its theoretical contexts, and looks to the future of research in a dynamic landscape in which ceramic production systems are undergoing rapid change. Many varieties of research currently now fall under the rubric of ceramic ethnoarchaeology, and Americanist archaeologist are encouraged to look beyond their own regionalist and theoretical paradigms to consult this wider literature.

Ceramic production and provenience at Gordion, Central Anatolia

Phrygian Gordion was the political center of an influential Iron Age polity that extended across west central Anatolia during the first half of the 1st millennium BC. Though the borders of this polity remain vague a characteristic of the Phrygian “footprint” is the distribution of highly distinctive ceramics. The extent to which Gordion potters were the originators of these wares remains uncertain. In this paper we use Neutron Activation Analysis (NAA) to establish the local signature of predominantly Iron Age ceramics for this site by combining samples from several decades of excavation with an extensive regional sediment sequence. We also compare previous NAA work at Gordion to suggest that the formative stages of the Phrygian state appears to have involved a more extensive network of non-local specialist producers than previously thought.     

Residential Mobility and Ceramic Exchange: Ethnography and Archaeological Implications

After the appearance of agriculture and subsequent increasing population densities and agricultural intensification, some mobile hunters, foragers, and part-time horticulturalists often obtained ceramic vessels from nearby villages. Mobile groups are firmly embedded within regional patterns of interaction and exchange. Certain regional interaction patterns encourage use of vessels made by a sedentary neighbor, and the factors that would discourage it are less significant than previously believed. The vessels made by neighboring agriculturalists may often be as well suited to the tasks and settlement pattern of mobile groups as vessels made by the mobile groups themselves. Given the probable frequency with which mobile groups discarded ceramics made by a neighboring group, archaeologists should consider this scenario when interpreting ceramic frequencies in remote small sites, where some ceramics may be far from the villages in which they were apparently made. Using an archaeological case study from the Western Papaguería of the US Southwest, I propose using vessel techno-function, along with other data, to place individual sites within a broader settlement system. The settlement system, rather than diagnostic ceramic types, may be most useful for assigning these sites to particular cultural traditions and for understanding patterns of landscape use.     

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.

Determining the provenance of black limestone artifacts using petrography,isotopes and EPR techniques: the case of the monument of Bocco

This paper investigates the provenance of the black limestone of the monument known as Bocco, named after the king of Mauretania who presented Silla with this work as a sign of his submission to the power of Rome. A multi-method approach, comprising petrographic observations, carbon and oxygen isotope composition and electron paramagnetic resonance (EPR) spectra characteristics, was used for this purpose. The monument is part of a reconstruction of a rectangular base (approx. 8 × 2 m) which is likely to have served as the base for a bronze statuary group and is currently composed of six blocks of limestone whose exterior is engraved with a fine frieze. The results of the different analyses were compared with the data of a published database of the most important black limestone quarries exploited during Roman times in the Mediterranean area. The petrographic and physico-chemical parameters did not prove to be very effective in determining the provenance of the black limestone of Bocco; the isotopes result even raised some uncertainty as to whether all six blocks came from the same quarry, though this doubt was dispelled by the EPR data and, above all, by the evident petrographic similarity between them. Differences in the isotopic composition of the various blocks may be due to an in situ rock alteration process caused by interaction with an aqueous fluid. It was, however, impossible to determine with certainty the origin of the material of the stone artifact using the database available; it is possible that the black limestone of Bocco came from an ancient quarry that is likely to be located in north western Africa but has not yet been uncovered. An alternative hypothesis, according to which the limestone used for the monument of Bocco came from the ancient quarry of Ain el Ksir, one of the Tunisian quarries present in the database, is also discussed.     

Ceramic Petrology and the Study of Anglo-Saxon and Later Medieval Ceramics

Abstract

A SURVEY of archaeological ceramic thin sections held by institutions and individuals in the United Kingdom was undertaken in the early 1990s by the City of Lincoln Archaeology Unit and funded by English Heritage. Over 6,000 thin sections of Anglo-Saxon or medieval date (or reports on their analysis) were located. For the Middle to Late Anglo-Saxon and the post-Conquest Periods, these studies have confirmed that pottery production was carried out in a limited number of centres and that most pottery, including handmade coarsewares, was therefore produced for trade. The distances over which pottery was carried vary from period to period but were actually as high or higher in the Middle to Late Anglo-Saxon Period as in the 13th to 14h centuries. However, for the Early Anglo-Saxon Period (and the Middle Anglo-Saxon Period outside of eastern England) the evidence of ceramic petrology is equivocal and requires more study. These 6,000–odd thin sections represent a resource which could be used for various future studies, some of which are discussed here, and as an aid to their further use a database containing information on the sampled ceramics, their location and publications of their analyses will be published online through Internet Archaeology.
