This third volume in the series is devoted to presenting and interpreting the metallurgical evidence from Ban Chiang, northeast Thailand, in the broader regional context. Because the production of metal artifacts must engage numerous communities in order to acquire and process the raw materials and then create and distribute products, understanding metals in past societies requires a regional perspective. This is the first book to compile, summarize, and synthesize the English-language copper production and exchange evidence available so far from Thailand and Laos in a thorough and systematic manner. Chapters by Vincent C. Pigott and Thomas O. Pryce examine in detail the mining and smelting of copper in several sites, and the lead-isotope evidence for the sourcing of artifacts found in two of the consumption sites included in the study. Another chapter compiles the metal consumption evidence, including results of technical studies on prehistoric metals recovered from more than 35 sites excavated in central and northeast Thailand. This compilation demonstrates important regional variation in chaînes opératoires, allowing explication and synthesis of the technological traditions found in this region during prehistory. The review and compilation sheds new light on the social and economic context for the adoption and development of metallurgy in this part of the world. One key insight is that Thailand presents a case for a "community-driven bronze age," where the choices of peaceful local communities, not elites or centralized political entities, shaped how metal technological systems were implemented in this region. This fresh perspective on the role of metallurgy in ancient societies contributes to an expanded global understanding of how humans have engaged metal technologies, contributing to debunking the conventional paradigm that emphasized a top-down view and a standardized metallurgical sequence, a paradigm that has dominated archeometallurgical studies for the last century or more.

The emergence and adoption of metallurgy is one of the seminal topics of investigation in the history of archaeology, particularly in the history of archaeological research in Southeast Asia. The site of Ban Chiang, Thailand, is a central site in debates surrounding the chronology and significance of early metallurgy in the region. This book is the first in a series of four volumes that review the contributions of Ban Chiang and three related sites in northeast Thailand excavated by the Penn Museum to an understanding early metallurgy in Thailand. As the study of archaeometallurgy is a complex topic that draws on numerous technical and social science disciplines, this introductory volume presents in several chapters the background needed to assess the metal and related evidence presented in the subsequent volumes in this series. A history of perspectives on the role of metals in ancient societies generally and Southeast Asia, specifically, is provided. Other chapters debunk the conventional paradigm for understanding metals and society and provide current theoretical perspectives and new paradigms for the study of ancient metals. The geological basis for the presence and location of metal ore resources in the region is reviewed. The final chapter presents a technical overview of ways material properties of ancient metals may be studied. While providing a background to the study of metals at Ban Chiang, the volume also reviews, synthesizes, and repositions the method and theory for the study of archaeometallurgy generally.

The foundation of archaeometallurgy is the study of excavated assemblages of metals and related remains. This volume presents in detail how the metals and such remains as crucibles excavated from four sites in northeast Thailand have been studied to understand the place of metal objects and technology in the ancient past of this region. In addition to typological examination, hundreds of technical analyses reveal the technological capabilities, preferences, and styles of metal artifact manufacturers in this part of Thailand. Detailed examination of contexts of recovery of metal remains employing a "life history" approach indicates that metal objects in those societies were used primarily in daily life and, only occasionally, as grave goods. The most surprising find is that casting of copper-base artifacts to final form took place at all these village sites during the metal age period, indicating a decentralized final production stage that may prove to be unusual for metal age societies. These insights are made possible by applying the methods and theories introduced in the first volume of the suite of volumes that study the metal remains from Ban Chiang in regional contest.

Excavated in 2009, An Son, Long An Province, southern Vietnam has been dated to the second millennium BC, with evidence for neolithic occupation and burials. Very little is known about the neolithic period in southern Vietnam, and the routes and chronology for the appearance of cultivation, domestic animals, and ceramic and lithic technologies associated with sedentary settlements in mainland Southeast Asia are still debated. The ways in which the ceramic material culture at An Son conforms to the wider neolithic expression observed in Southeast Asia is investigated, and local and regional innovations are identified. The An Son ceramic assemblage is discussed in great detail to characterise the neolithic occupation, while considering the nature of craft production, manufacturing methods and the transference of traditions. Contextualising the neolithic in southern Vietnam is conducted through a comparative study of material culture between An Son and the sites of B?n Ðò, Bình ?a, Cù Lao Rùa, Cái V?n, C?u S?t, ?a Kai, ?ình Ông, L?c Giang, R?ch Lá, R?ch Núi and Su?i Linh, all in southern Vietnam. Another analysis is presented to contextualise An Son in the wider neolithic landscape of mainland Southeast Asia, between An Son and Ban Non Wat, early Ban Lum Khao, early Ban Chiang, early Non Nok Tha, Khok Charoen, Tha Kae, Khok Phanom Di, Nong Nor (phase 1), Samrong Sen, Laang Spean, Krek, Bàu Tró, Mán B?c and Xóm R?n. The aspects of material culture at An Son that appear to have ancestral links are considered in this research as well as local interaction spheres.
