SHANGHAI, CHINA—A team of scientists led by Yu Li of Fudan University has conducted proton-induced X-ray emission analyses of pieces of proto-porcelain and fragments of impressed stoneware collected at the site of the Piaoshan kiln. The site is thought to date to China’s first dynasty, between 2070 and 1600 B.C. Samples from five other early kiln sites in the vicinity were also tested. They found that the samples from the six kiln sites each had distinct chemical profiles, which may indicate that the raw materials used to produce the pots had been procured locally. “The research clearly shows the relationship of inheritance of early Chinese proto-porcelain, and fills the large gaps in knowledge regarding the origin of Chinese proto-porcelain,” Yu Li said in a press release.
