Trace levels of iridium in ancient silver artefacts can provide information on the sources of silver-bearing ores as well as the technologies used to extract silver. A geographically and chronologically disparate legacy dataset, comprised of Near Eastern objects from the Sasanian and Byzantine Empires (1st Millennium AD) and coins circulating around the Mediterranean in the mid-1st Millennium BC, shows that Ag-Au-Ir log-ratio plots can help identify silver derived from the same mining areas, as well as broadly differentiating between the ore types exploited. Combining trace element and lead isotope analyses through the Pb crustal age of the ore, further delimits interpretations on the compositions and locations of silver ore sources. Furthermore, it is shown that silver artefacts of Near Eastern origin have exceptionally high iridium levels, suggesting a unique silver-bearing ore source, potentially in the Taurus mountain range of southern Anatolia. The wide range of crustal ages identified for ancient Greek coins and Near Eastern objects suggest that the addition of exogenous lead as a silver collector during smelting was common practice in the Near East as early as 475BCE. The practice of mixing silver from different sources has also been identified by triangulating the log-ratio subcomposition plots, Pb crustal ages of the ore from which the silver derived and absolute values of trace levels of gold and iridium in silver artefacts.

Making the most of expert knowledge to analyse archaeological data: a case study on Parthian and Sasanian glazed pottery

Jonathan R. Wood, Michael Greenacre

Summary: Analyzing the chemical compositions of Parthian and Sasanian glazed pottery using statistical methods and expert knowledge can help identify the production practices of Mesopotamian glass and glaze producers. It was found that the silica sources used in later glazes were purer and more standardized. This suggests the possibility of undiscovered glass production centers associated with urbanization in southern Mesopotamia during the Parthian-Sasanian transition.

Technology, life histories and circulation of gold objects during the Middle Period (AD 400-1000): A perspective from the Atacama Desert, Chile

Maria Teresa Plaza Calonge, Valentina Figueroa Larre, Marcos Martinon-Torres

Summary: Studies of archaeological goldwork in the south-central Andes region have often focused on visually striking artefacts, ignoring the potential complexity and cultural significance of gold technology in the area. Using a life-history approach, this study examines gold and silver objects from northern Chile through chemical and microscopic analyses. The results reveal diverse compositions, techniques, and skill levels, suggesting that gold artefacts were imported from various areas in the south-central Andes and used in different ways, including small-scale production and modifying imported objects. This research highlights the significance of integrative approaches in understanding the cultural context and production methods of archaeological goldwork.

Other ways to examine the finances behind the birth of Classical Greece

Jonathan R. Wood

Summary: This article proposes that the birth of Classical Greece was influenced by the economically minded government under the Peisistratid tyrant Hippias. The introduction of new silver technology during the time of the Peisistratids allowed for the exploitation of silver-bearing lead ores, which financed the construction of a war navy. Against the backdrop of the threat of war with Persia and an imminent Spartan invasion, Greece adopted this labor-intensive silver technology, ultimately leading to the radical social experiment of Classical Greece.

Smelting copper in decorated pottery: communities of practice in the Niari Basin, Republic of the Congo, fifteenth-seventeenth centuries CE

Braden W. Cordivari, Nicolas Nikis, Marcos Martinon-Torres

Summary: This paper examines copper production in the Niari Basin, Republic of the Congo, from the mid-fifteenth to the mid-seventeenth centuries CE. Using various analytical methods, the study evaluates the microstructure and composition of slags and technical ceramics from sites associated with two different pottery traditions. The research finds that both sites used refractory domestic pottery as crucibles for copper smelting, and identifies a unique type of crucible in sub-Saharan Africa.

Refining silver at the castle: the rare case of a large early modern cupel from Middelburg-in-Flanders, Belgium

Lise Saussus, Yi-Ting Hsu, Maxime Poulain, Marcos Martinon-Torres, Nicolas Thomas, Wim De Clercq

Summary: Ash cupels were commonly used in small-scale refining of noble metals in early modern Europe. This study presents the analysis of a large cupel recovered from Middleburg Castle in Belgium and discusses its historical context and manufacturing methods. The cupel was made of bone ash mixed with another calcareous material and was likely used for refining heavily debased silver. Simple methods for investigating cupel manufacturing and metal refining, as well as evaluating cupellation performance in archaeological contexts, are illustrated.

A Multivariate Approach to Investigate Metallurgical Technology: The Case of the Chinese Ritual Bronzes

Jonathan R. Wood, Yaxiong Liu

Summary: Research into ancient Chinese metallurgy has progressed in recent years, but analyzing artifacts alone cannot reveal the relationship between technology and society. This study applies a multivariate approach and finds that copper and lead used in ancient Chinese bronzes were sourced from the same deposits rather than different regions.

Iron production in the Qin state during the late Warring States period: a cost-efficient technological system

Yaxiong Liu, Kunlong Chen, Marcos Martinon-Torres

Summary: This paper characterizes 43 iron artefacts from Qin civilian burials in the Guanzhong Plain, dating back to the late Warring States period, through metallography and slag inclusion analysis. By analyzing these results with previous data, correlations among artefact functions, materials, and manufacturing techniques are identified, suggesting the existence of a complex and cost-efficient technological system. The study argues that a cast iron-based iron production industry was established in the Qin state no later than the late Warring States period to meet civilian needs.

Archaeological science, globalisation, and local agency: gold in Great Zimbabwe

Jasmine Vieri, Shadreck Chirikure, Paul Lane, Marcos Martinon-Torres

Summary: Great Zimbabwe, from 1000 to 1600 CE, was known for its cultural innovations and involvement in trans-Africa and trans-Indian Ocean exchange. Recent excavations uncovered fragments of over a hundred gold processing vessels made of alumina-rich clays. These ceramics were used for refining and collecting gold at high temperatures, suggesting a significant role of local agency and gold consumption. The findings challenge simplified narratives of globalization and highlight the improvisation-laden production and consumption in homesteads throughout Great Zimbabwe's settlements.

Summary: Chemical treatment of skeletal remains can reduce overall DNA quality and quantity but has no significant impact on stable isotope ratio analysis. Examination of treated and untreated human remains through histological and stable isotope analysis reveals that treated remains exhibit better preservation compared to untreated remains. Stable isotope ratio analysis is viable for both treated and untreated remains, regardless of their origin.

Searching for traces of human activity in earthen floor sequences: high-resolution geoarchaeological analyses at an Early Iron Age village in Central Iberia

Laura Tome, Eneko Iriartec, Antonio Blanco-Gonzalez, Margarita Jambrina-Enriquez, Natalia Eguez, Antonio V. Herrera-Herrera, Carolina Mallola

Summary: This paper presents the outcomes of a microcontextual geoarchaeological study conducted on earthen dwellings from the Early Iron Age village of Cerro de San Vicente. The study employed soil micromorphology, lipid biomarker analysis, XRD, and XRF analyses to investigate various aspects of the dwellings, including construction materials, site formation processes, and daily life practices. The results have shed light on the construction layers, floor use, maintenance, repaving, periods of abandonment and decay, and the presence of lipid biomarkers associated with dwelling functionality. The study significantly contributes to our understanding of ancient construction practices and the utilization of domestic spaces during the Early Iron Age.
