Ceramic traditions and technological choices revealed by early Iron Age vessels: the case of Vetulonia (southern Tuscany)

Early Iron Age pottery from central Italian regions has so far largely been studied with a particular emphasis on typological and stylistical features. However, an analytical approach to ancient ceramic technology can reveal a wealth of data on the know-how of early Iron Age central Italian craftspeople and their production choices. With this aim we conducted archaeometric analyses of forty vessels from one of the main protohistoric cemeteries of Vetulonia, coupled with geological surveys of the territory around the settlement and the collection of raw materials. The occurrence of a ceramic fabric marked by fragments of metasedimentary rocks, as opposed to a fabric tempered with flint fragments, indicates the existence of separate traditions, characterised by distinct processes and the addition of specific tempers, probably reflecting different technological practices. The significance of our findings is briefly discussed within the historical and social scenario of early Iron Age Vetulonia, at the dawn of urbanisation

'Seeing Shit': Assessing the Visibility of Dung Tempering in Ancient Pottery Using an Experimental Approach

Widespread ethnographic evidence exists for the addition of animal dung to clay during the process of ceramic production. However, conclusive evidence of dung tempering in archaeological ceramics is relatively rare. The aim of this study is to ascertain whether, and under which conditions, dung tempering of pottery is identifiable. To answer these questions, we assessed whether a combination of micro-particle analysis in loose sediment and thin-section petrography can reveal the addition of dung to the clay paste by focusing on faecal spherulites, ash pseudomorphs, phytoliths and coprophilous fungal spores. We analysed several series of experimentally produced ceramic briquettes tempered with different types of dung and dung ash, which were fired at a range of increasing temperatures. Our study shows that the identification of dung tempering represents a challenge, and it depends on a number of different factors, among others the original presence of dung markers in the dung used, the manufacturing process, the firing temperatures and the firing atmosphere. Overall, through a multidisciplinary approach, our work clarifies a variety of issues connected to the identification of dung in ancient pottery, highlighting the role of faecal spherulites as the most promising proxy

A compositional and technological reassessment of the function of potters’ marks on Early Bronze Age sherds from Tell el-‘Abd, Syria

A highly distinctive feature of the Early Bronze Age ceramic assemblage of the site of Tell el-‘Abd in northern Syria is the presence of large numbers of pots that were incised with a diverse range of symbols prior to firing. Several hypotheses have been proposed to explain the function of such ceramic “potters’ marks”. One is that they functioned as a signature or trademark used by potters or workshops to identify their work. Another possibility is that they were used for quality control or accounting purposes during manufacture. Alternatively, they may have signified vessels intended for specific customers, or the size or contents of the vessels. In the case of the Tell el-‘Abd potters’ marks, distinguishing between these possibilities has proven difficult based upon their macroscopic examination and archaeological context alone. The present research, therefore, attempts to shed further light on the function of the potters’ marks by studying the clay paste recipes of 33 ceramic samples using scientific methods. Thin section petrography, instrumental geochemistry and scanning electron microscopy have been used to characterise and classify sherds according to their raw materials and manufacturing technology. This has been compared to the type of potters’ mark and other archaeological information in order to test the hypotheses that the distinctive ceramic markings signified ceramics made at different production centres or distinguished between different artisans operating at the same workshop

Pottery technology at the dawn of metallurgy in the Vinča culture

This chapter summarises the macroscopic and microscopic analyses of pottery sherds from the sites of Belovode and Pločnik, presented in Chapters 14 and 31, and provides insight into different technological traits in order to aid reconstruction of pottery making recipes in these two Vinča culture communities. Using a multi- pronged scientific approach, we reconstructed routines of raw material acquisition and processing, techniques of forming and finishing vessels, firing conditions and organisational aspects of pottery production. The possible non-local production identified in this research is also considered in order to understand the dynamics that shaped pottery circulation in these prehistoric communities (e.g. Quinn et al. 2010). These results also contribute significantly to the previous technological studies carried out on Neolithic pottery from sites in the central Balkans (Figure 1) (e.g. Dammers et al. 2012; Kaiser 1984, 1989, 1990; Kaiser et al. 1986; Kreiter et al. 2009, 2011, 2013, 2017a, 2017b, 2019; Spataro 2014, 2017, 2018; Szakmány et al. 2019)

Pyrotechnological connections? Re-investigating the link between pottery firing technology and the origins of metallurgy in the Vinča Culture, Serbia

The present paper re-examines the purported relationship between Late Neolithic/Early Chalcolithic pottery firing technology and the world's earliest recorded copper metallurgy at two Serbian Vinča culture sites, Belovode and Pločnik (c. 5350 to 4600 BC). A total of eighty-eight well-dated sherds including dark-burnished and graphite-painted pottery that originate across this period have been analysed using a multi-pronged scientific approach in order to reconstruct the raw materials and firing conditions that were necessary for the production of these decorative styles. This is then compared to the pyrotechnological requirements and chronology of copper smelting in order to shed new light on the assumed, yet rarely investigated, hypothesis that advances in pottery firing technology in the late 6th and early 5th millennia BC Balkans were an important precursor for the emergence of metallurgy in this region at around 5000 BC. The results of this study and the recent literature indicate that the ability to exert sufficiently close control over the redox atmosphere in a two-step firing process necessary to produce graphite-painted pottery could indeed link these two crafts. However, graphite-painted pottery and metallurgy emerge at around the same time, both benefitting from the pre-existing experience with dark-burnished pottery and an increasing focus on aesthetics and exotic minerals. Thus, they appear as related technologies, but not as one being the precursor to the other

Early metallurgy in Sardinia: characterizing the evidence from Su Coddu

This paper contextualizes analyses of a collection of metal artifacts and ostensible metallurgical slag from the prehistoric settlement of Su Coddu in south-central Sardinia (ca. 3400–2850 BCE). To characterize the types of metals and associated alloys utilized by the earliest residents of Su Coddu, two pins and an unshaped lump of unknown composition were analyzed using portable XRF spectrometry. In addition to metal artifacts, a large quantity of putative slag was discovered at the site that is consistently cited as the earliest evidence of in situ smelting in prehistoric Sardinia. To reconstruct firing temperatures and characterize mineral phases, four samples of the overfired material were selected for thin section petrography and powder XRD analysis. The results of this study indicate that the two pins were made of copper while the unshaped lump was composed of pure lead, making it the earliest lead-based artifact on Sardinia. XRD and petrographic analyses of the fired “slags” reveal that these samples are unrelated to metallurgical smelting and are likely burnt wall coatings whose mineralogical phases correspond with unfired plasters also recovered from the site. These results in combination contribute towards understanding early metallurgical practices in Sardinia and are relevant in reconstructing the events that have shaped the life history of Su Coddu

Playing with fire: Exploring ceramic pyrotechnology in the Late Neolithic Balkans through an archaeometric and experimental approach

Addressing ceramic pyrotechnology plays a key role in understanding a wide range of cultural and social behaviours associated to pottery production. Firing is the process which transforms clay into ceramic, which is one of the most frequently preserved materials in the majority of Neolithic and later archaeological sites. Though firing temperatures and the functions of various pyrotechnological installations have been extensively investigated in archaeology, both have often been addressed separately. Most of our knowledge on firing structures and procedures in the Neolithic are still largely based on ethnoarchaeological evidence. To move forward, we need to consider all aspects involved in ancient pyrotechnology, together with use of additional investigative tools. This study aims to address Neolithic pottery firing from a diverse perspective that merges archaeometric analyses and experimental archaeology. To demonstrate the potential of this approach, we combined an archaeometric case study of pottery from the late Neolithic (5200–4800 BCE) from the site of Gradište-Iđjoš (Serbia) with experimental pit firings, likely one of the mostly frequently employed firing techniques used in prehistoric periods. Scientific analyses include X-ray powder diffraction (XRPD), scanning electron microscopy (SEM), and ceramic petrography. These methods were run on both archaeological materials and experimental reproductions. Additionally, a detailed program of firing temperature monitoring, integrated observations on atmospheric conditions, soaking time, and duration were recorded to contribute to the study. The experiments enabled us to collect results useful for our understanding of the pyrotechnological knowledge of Neolithic potters from a technological and social point of view. In addition, they demonstrated the potential of a dedicated methodological framework for studying pottery firing that can be applied to other chronological and cultural contexts

Four centuries of cooking wares at Priene: Tracing transformation in supply and trade patterns in western Asia minor (Turkey)

This paper presents the results of a diachronic and multidisciplinary investigation into the production and consumption of cooking ware in the ancient city of Priene (Turkey). Three major chronological horizons are considered, covering the fourth to the first century BCE: the late Classical/early Hellenistic period, the middle Hellenistic period, and the late Hellenistic/early Roman Imperial period. Following a thorough typological and macroscopic study of fabrics, an integrated analytical approach combining petrography and elemental analysis (wavelength dispersive X-ray fluorescence) was applied to investigate the main macroscopic types and fabrics that characterised cooking wares. Integration of the results from the typological study with the subsequent analyses of 90 representative samples has provided high-resolution insights into cooking ware production and consumption at Priene over the study period. In addition to tracing transformations in local and regional manufacture over time, the results show that cooking wares were imported to the city from several places and, moreover, at a scale at least equivalent to that for other categories of ceramic vessels at that time. Changes in the manufacturing technology of local and regional products and the origin of imports are discussed in the context of significant historical developments that took place in this region over the period covered by the study
