Pottery

Porcelain is made from a hard paste made of the clay kaolin and a feldspar called petuntse, which cements the vessel and seals any pores. China has become synonymous with high-quality porcelain. Most china pots comes from the city of Jingdezhen in China's Jiangxi province. Jingdezhen, under a variety of names, has been central to porcelain production in China since at least the early Han Dynasty.

The most noticeable difference between porcelain and the other pottery clays is that it "wets" very quickly (that is, added water has a noticeably greater effect on the plasticity for porcelain than other clays), and that it tends to continue to "move" longer than other clays, requiring experience in handling to attain optimum results. During medieval times in Europe, porcelain was very expensive and in high demand for its beauty. TLV mirrors also date from the Han dynasty.
