The Technology of Large-Scale Zinc Production in Chongqing in Ming and Qing China (BAR International)

This book presents the analyses, technical interpretation and socio-economic contextualisation of the production remains of zinc distillation from three Ming sites in Fengdu and one Qing site in Shizhu, Chongqing, southwest China. Zinc ore, zinc metal, retorts and slag from these sites were analysed by OM, SEM-EDS, EPMA-WDS and XRD. Following on from a detailed technological reconstruction, some differences were found between the zinc distillation technologies in Fengdu and Shizhu, not only in technical efficiency but also in the organisation of production, which can be explained as adaptation of the zinc production for coinage to the different social, political and economic constraints affecting each group of sites. This book then contextualises and discusses the significance of Chinese zinc production with reference to coinage in Ming and Qing China, but also by comparing it to other brass- and zinc-making technologies in China, India and Europe, and by assessing the influence of Chinese zinc in the international maritime trade.
