Hailian Chen’s pioneering study presents the first comprehensive history of Chinese zinc—an essential base metal used to produce brass and coin and a global commodity—over the long eighteenth century. Zinc, she argues, played a far greater role in the Qing economy and in integrating China into an emerging global economy, than has previously been recognized. Using commodity chain analysis and exploring over 5,800 items of archival documents, Chen demonstrates how this metal was produced, transported, traded, and consumed by human agents. Situating the zinc story within the human-environment framework, this book covers a broad and interdisciplinary range of political economy, material culture, environment, technology, and society, which casts new light on our understanding of early modern China.
Sui-Wai Cheung’s study of the institutional history of copper coins in the Ming dynasty reveals how emperors and statesmen perceived and used the copper coins at their disposal. In this process, he uncovers the reality of the Sons of Heaven, showing that although Ming emperors seemed to have unlimited power, they could not afford the upkeep on their palace. In this revealing history of Ming China, Cheung argues that especially after the breakdown of the household registration system, the aim of the Ming coinage system was to create a new source of income in order to maintain the emperor's domain in Beijing.
