A new perspective on vessels usage in the Yangshao culture: Were amphorae brine purification devices?

The jiandiping 尖底瓶 amphora is a distinctive pottery type of the Yangshao culture (5000 − 3000 BCE), predominantly found along the middle course of the Yellow River, with a significant concentration in the Wei River Valley. Despite its widespread presence, the function of this vessel has remained elusive in scholarly discourse. This article investigates the amphora’s spatial relationship to salt deposits and examines its physical characteristics, evaluating these aspects within the context of the Yangshao population’s lifestyle in the Wei River Valley. By incorporating evidence from Shang dynasty oracle bone inscriptions and various ethnoarchaeological studies, we propose a new interpretation of the jiandiping amphora as a tool for salt processing. This study prompts a reevaluation of Neolithic cultural and technological practices, highlighting the Yangshao society’s potential involvement in salt exploitation in the Wei River Valley.
