Porcelain is a kind of ceramics made from kaolin at high temperature. The earliest ceramics in China appeared in the Shang Dynasty (c.1600–1046 BCE). And the production of ceramics laid the foundation for the invention of porcelain. The history of Chinese porcelain can be traced back to the Han Dynasty (206 BC – 220 AD). In the Tang Dynasty, porcelain was divided into celadon and white porcelain. In the Song Dynasty, Jingdezhen was selected as the royal porcelain production centre and began to produce blue and white porcelain.
