Book excerpt: 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.
