Sulfur Manufacturing at Hot Springs in Early Modern Chinese Borderlands

What is it about?

This article examines sulfur manufacturing and refining methods in the early modern Chinese borderlands in the context of global trade and tribute networks. The increasing demands for high-quality sulfur, crucial for gunpowder and mineral drugs, facilitated the further development of sulfur-production and -refining techniques. Constrained by limited local sulfur deposits, sulfur production in China proper relied primarily on domestic pyrite ores or pyritic nodules in coal mines, alongside imports from the Ryukyu Islands. This article focuses on case studies of various local practices in the natural sulfuric hot springs region of China’s borderlands, particularly in Yunnan and Taiwan from the sixteenth to the twentieth centuries. It examines alternative methods of sulfur manufacturing that utilized geothermal resources at hot springs for various local and regional military and medical demands in global contexts.
