China has a long history in porcelain, which developed from pottery making. The ceramic history can be traced back to the Neolithic age. Along with the development of ceramics,in the early period of the Shang dynasty (1783-1134 BC), the original green porcelain, or celadon, appeared.

Porcelain did not come easily. After several thousand years of hard work, the early potters accumulated rich experience in their craft. The earliest porcelain appeared in the slave societies of the Shang and Zhou dynasties.
