Salt Production of Late Imperial China in the Upper Three Gorges Region: A Case Study of the Zhongjingba Site in Chongqing

Abstract

ABSTRACTThis article aims to improve the understanding of salt production in the upper Three Gorges region, based on archaeological investigation and excavation of salt-production sites in Yushan, Pengshui County, Chongqing. This article introduces the features of salt sources and the types and dates of the salt wells in Yushan, and investigates the local brine transportation and salt-making techniques. The Zhongjingba site is a large salt-making site with well-preserved remains of production and support facilities dating from the 18th and 19th centuries. Large numbers of evaporation furnaces, brine tanks, and working pits have been excavated and revealed a complete process of producing salt. Analysis of historical documents and the excavated remnants has allowed the reconstruction of the po lu yin zao salt-making process (which, in Chinese, means to splash brine onto the evaporation furnace), the first archaeological evidence of this technique; the management, output capacity, and sales area of the ancient salt production in Yushan are also discussed.
