Proto-porcelain is the primitive form of Chinese porcelain.The peak of proto-porcelain production occurred during the Spring and Autumn period.There was a transitional period around the time of Spring and Autumn during which the type and the technology gradually developed from Western Zhou Dynasty and contributed to the prosperity of Warring States Period.Based on a comprehensive systematic typological study on the proto-porcelain in the Spring and Autumn period of the Jiangnan region,this paper refined the chronology into three phases and six section.In the Early Spring and Autumn period,the types of artifacts are rich,complex and include diverse decorations.From the Middle Spring and Autumn period,the type and decoration tend to be simplified.In the Late Spring and Autumn period,plain cup bowls became dominant.However,since the second stage,the quality of the glaze has been significantly improved,which laid a solid technical foundation for the development of the proto-porcelain in the Warring States period.
