A preliminary study of ceramic pastes in the copper age pottery production of the Rome area

This paper presents the preliminary results of an analytical study on domestic pottery samples originating from the Copper Age sites of Casetta Mistici, Tor Pagnotta, Osteria del Curato-Via Cinquefrondi, Torre della Chiesaccia and Valle dei Morti, all of which are located in the Rome area (Latium, Italy). The aim of this research is to define the compositional features of the ceramic pastes and to reconstruct the main technological choices characterising pottery production in these contexts. The importance of these archaeological sites lies in their geographic position, being located in an area bounded by the Tiber and Aniene rivers and the Colli Albani volcano, and in their stratigraphic sequence, spanning from the mid-fourth to the end of the third millennium bc. This research, based on a petrographic and chemical investigation of pottery samples, led to the distinction of eight petrographic groups that reflect specific choices in pottery production. Moreover, the analytical results provide indications about the prehistoric pottery production of the Rome area in relation to the ceramic recipes used, the pastes that were obtained and their sourcing areas.     

Building Forcello: Etruscan wattle-and-daub technique in the Po Plain (Bagnolo San Vito,Mantua, northern Italy)

The study analyses through an interdisciplinary approach the wattle-and-daub building technique used on the Po Plain of northern Italy, focusing on the archaeological evidence from the Etruscan site of Forcello, near Bagnolo San Vito (Mantua) (540–375 bce ). Wattle and daub is widespread across different times and periods, and is particularly common in regions such as the Po Plain, where stone sources for construction are not immediately available. Thanks to a combined archaeometric, geological and anthracological study, the paper provides new insights on a fifth-century bce building structure from Forcello. The findings reveal information on the life history of this feature, including its construction, maintenance and final destruction. The research also sheds a new light on the wattle-and-daub technique and on the interaction between people and the Po Plain Etruscan palaeoenvironment.     

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.     

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.     

1500 Years of Pottery: Neutron Activation Analysis of Northern Chilean Domestic Ceramics from Caleta Vitor and Clay Samples from Nearby Valley,Coast and Highland Contexts

This paper presents the findings arising from neutron activation analysis (NAA) of northern Chilean domestic ceramic samples from Caleta Vitor (n = 38) and clay samples (n = 15) from nearby valley, coast and highland contexts. This study presents the first NAA data set of ceramics spanning a temporal period of 1500 years (c.2000 to c.476 bp ) from the Vitor Valley as well as the first attempt to use NAA to characterize potential clay sources in the region. On the basis of this study, we argue that the majority of domestic ceramics from Caleta Vitor share compositional similarities with clay samples collected from nearby valleys, allowing us to infer that the Caleta Vitor populations primarily procured their clay for domestic ceramics from local sources throughout a 1500‐year period. Thus, despite the fact that there were inter‐regional interactions during this period that included the influence of powerful Andean polities, it would appear that domestic ceramics continued to be produced locally, and by implication it can be argued that such interactions did not substantially affect this sphere of material culture production. Further, the apparent continuities in domestic ceramic production allow us to reflect on local decision‐making processes throughout the cultural phases considered in this research.     

Temper mixture models and assessing ceramic complexity in the emerging Tarascan state

This study presents compositional data from ceramics drawn from surface survey and controlled excavations from three prehispanic sites within the relatively small Lake Pátzcuaro Basin, representing a ceramic sequence stretching nearly 1500 years, from the Preclassic to Late Postclassic Tarascan state (ca. 50 B.C.–1525 A.D.). Using neutron activation analysis, we identify compositional groups and model the importance of volcanic materials as temper in the construction of prehispanic ceramics by matching mathematical simulations of clay–ash mixes to the compositional groups. Rather than discreet clay resources and spatially circumscribed production, we argue for a broadly dispersed and highly varied organization of pre-Tarascan and Tarascan state ceramic production in which the potters' distribution and use of specific volcanic ashy additives, not clays, structured the organization of production.     

The Compositional study of ceramic samples from tombs dating to the Zhou Dynasty at Xiaoshan,Zhejiang Province (China)

Xiaoshan in Zhejiang Province was an important ceramic production area in ancient China. During recent years, local archaeologists have found a number of mound tombs dating to the Zhou Dynasty and the Spring and Autumn period. Many shards of stamped stoneware and proto‐porcelain have been unearthed from these tombs. In this paper, we report how we collected ceramic shards from tombs and samples from local ancient kilns as reference materials in order to clarify their relationship. We have used the energy‐dispersive X‐ray fluorescence technique to analyse the chemical composition of the ceramic samples. The results indicate that some of the tomb artefacts may be imported from other production areas. We infer that the other tomb samples were produced at local kilns, but due to production process–related compositional differences, there are small differences in chemical composition between different categories of samples.     

CHARACTERIZATION OF PLASTERS AND MORTARS AS A TOOL IN ARCHAEOLOGICAL STUDIES: THE CASE OF LARDIRAGO CASTLE IN PAVIA,NORTHERN ITALY*

Plasters and mortars from Lardirago Castle (Pavia, northern Italy) have been characterized by means of petrographical and chemical analyses in order to achieve technical and historical evidence of material production. The study focused on the oldest nucleus of the structure, where hidden plastered masonry has been discovered recently. Textural and compositional data of the binder and the aggregate fractions were collected by means of optical microscopy and electron microscopy coupled with microanalysis. These data permit the identification of building materials with similar technical and compositional characteristics, which can be related to different building phases.     

Khao Sam Kaeo – an archaeometallurgical crossroads for trans-asiatic technological traditions

Recent archaeological investigations at Khao Sam Kaeo, on the Upper Thai-Malay Peninsula, have furnished evidence for a mid/late 1st millennium BCE cultural exchange network stretching from the Indian subcontinent to Taiwan. Typological, compositional and technological study of Khao Sam Kaeo's copper-base artefacts has identified three distinct copper-alloy metallurgical traditions, with reasonable analogies in South Asian, Vietnamese, and Western Han material culture. Furthermore, analyses of technical ceramic and slag suggest that Khao Sam Kaeo metalworkers may have been using a cassiterite cementation process to produce high-tin bronze ingots for export or onsite casting/forging. Not only would this industry constitute the earliest evidence for the exploitation of Peninsula tin resources, but we also offer a speculative argument for the source of Khao Sam Kaeo's copper-base production technology.     

The iron age in Mediterranean France: Colonial encounters, entanglements, and transformations

During the last seven centuries of the first millennium BC, the indigenous societies of Mediterranean France underwent a series of gradual social and cultural transformations that are linked in complex ways to their encounter and increasing entanglement with the broader Mediterranean world. This article presents a synthesis of current knowledge of this issue and explores some of the main themes guiding research. New evidence concerning the alien colonial agents (Etruscan, Greek, Punic/Iberian, and Roman), and the contrasting nature of their presence and power in the region, is discussed, as is evidence concerning forms of indigenous engagement with colonial states and paths of social and cultural change. The consumption of alien goods (wine, ceramics) and the adoption of foreign techniques and practices (ceramic production methods, coinage, writing) are examined in terms of the locally situated logic of demand and the ramifications for entanglement and change. Transformations in settlements, ritual spaces, funerary practices, and the agrarian landscape are discussed.     

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.     

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.     

COMPARATIVE STUDY OF VARIOUS SAMPLES OF ETRUSCAN BUCCHERO BY X-RAY DIFFRACTION,X-RAY SPECTROMETRY,AND THERMOANALYSIS

In order to ascertain whether the technology of Etruscan bucchero was similar everywhere or showed local variation, a comparative study was carried out on 23 samples of bucchero from different sites. The use of carbon dust as a black pigment in this type of pottery was confirmed in all samples, while the hypothesis of the addition of MnO₂ as a colouring was disproved. Further information on the nature of the basic constituents of Etruscan bucchero was also provided.     

The Source Provenance of Bronze Age and Roman pottery from Cyprus

Archaeological interpretations of ancient economies have been strengthened by chemical analyses of ceramics, which provide the clearest evidence for economic activity, and comprise both the objects of exchange and its means. Pottery is often manufactured from local materials, but its compositional diversity typically prevents significant patterns of resource utilization from being identified. Centrally located and positioned on traditional shipping routes, Cyprus maintained ties with and supplied a variety of distinctive ceramic products to the major commercial centres in the eastern Mediterranean throughout Antiquity. We analysed two Cypriot .ne wares and a variety of utilitarian pottery, as well as samples of extant Cypriot clays to determine source provenance. These chemical analyses provide an objective indication of the origins of ancient (Bronze Age and Roman) ceramics manufactured on Cyprus. The distribution of the probable clay sources and the links between pottery style and the material environment also afford a perspective on the spatial organization of large‐scale pottery production on the island. Compositional analysis provides the means to assemble geographies of pottery production and to unravel the interregional system of exchange that operated in Antiquity, but the ability to accomplish these tasks is predicated on systematic analyses of ceramic products and raw materials that are found far beyond the bounds of individual archaeological sites.     

Phoenician–Punic amphorae in northern coastal Etruria: New evidence from Pisa (Italy)

This study outlines the circulation of Phoenician–Punic amphorae in northern coastal Etruria, with a particular focus on Pisa (Italy), where their presence has been attested since the mid-eighth century BCE. A set of specimens from Piazza del Duomo was analysed by minero-petrographic and geochemical techniques. The results were compared with literature data from Mediterranean production areas. The research allowed a better definition of the role of Etruscan Pisa in the frame of commercial and cultural routes in the Mediterranean, specifically in the Tyrrhenian area, also providing the opportunity to review the attestations of Phoenician–Punic amphora on a regional scale.     

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.     

Chemical characterisation of anthro-technosols from Bronze to Middle Age in Bologna (Italy)

The aim of this research was the understanding of a peculiarly expanded soil sequence in Bologna (i.e., Roman Bononia, Etruscan Felsina), one of the most important archaeological poles for Etruscan colonisation and settlement in northern Italy. The uppermost part of the chronological sequence dating from the Bronze Age up to medieval and modern times was analysed for the first time from geochemical and pedological viewpoints. The integration of archaeological, stratigraphical and pedological data supported by soil chemical analysis, a fundamental key for reconstructing a correct evolutionary sequence, made it possible to recognise seventeen buried Soil Units (ancient Technosols, Anthrosols and Cambisols) characterised by different kinds and degrees of intensity of anthropogenic influence. In some cases, the results show a relatively severe element concentration (Cu, Sn) mainly characterising the Iron Age (Etruscan and Villanovan) stratigraphic units, representing an ancient industrial pollution linked to local dispersal of melting activity dump products generated in near-site surrounding areas. Therefore, a comparison was possible between natural blank and anthropogenically polluted geochemical values for some local soils.     

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.     

New compositional data on ancient mortars from Hagia Sophia (Istanbul,Turkey)

This study shows the results of a multidisciplinary collaboration between the University of Calabria (Italy) and the National Autonomous University of Mexico (UNAM), about the compositional characterization of some mortars taken from Hagia Sophia in Istanbul (Turkey), one of the most important buildings in antiquity. Twenty samples of joint mortars were analysed by micro-chemical analyses (SEM-EDS), X-ray powder diffraction (XRPD), optical microscopy (OM) and transmission electron microscopy (TEM). The compositional study allowed us to define, with more detail, the construction phases of the fifth, sixth and tenth century. The petrographic analysis in thin section by optical microscopy showed four typologies of sands, used as aggregate, with specific compositional features. SEM-EDS analyses and TEM observations of the binder around the ceramic fragments of the aggregate showed the presence of different morphologies of single C-S-H compounds.     

Technology Transfer at the Periphery of the Mycenaean World: The Cases of Mycenaean Pottery Found in Central Macedonia (Greece) and the Plain of Sybaris (Italy)*

The study of technology transfer in pottery production to the periphery of the Mycenaean world has been addressed by considering two different areas, southern Italy and central Macedonia. Technological features such as ceramic paste, decoration and firing have been determined for different ceramic groups established according to provenance criteria. The studies of technology and provenance have been performed following an archaeometric approach, using neutron activation analysis, petrographic analysis, X‐ray diffraction and scanning electron microscopy. The results have revealed the existence of two different models. On the one hand, southern Italy seems to exhibit a more organized pottery production, which follows a Mycenaean‐like technology, while in central Macedonia production is probably more varied, being based in part on the technology of the local tradition.
