The kaolin confers plasticity on the paste and secures retention of form for the ware when exposed to the heat of the kiln, whilst the petuntse gives the translucency so characteristic of porcelain.
Kaolin is a hydrous aluminium silicate, having the formula HiA^SijOg, or AUSiaOr^H^, but in common clay this silicate is largely mixed with impurities.
The origin of kaolin may be traced to the alteration of certain aluminous silicates like feldspar, scapolite, beryl and topaz; but all large deposits of china-clay are due to the decomposition of feldspar, generally in granite, but sometimes in gneiss, pitchstone, andc.

 Kaolin Mining
Kaolin is one of several types of clay, and is commonly referred to as China Clay or Paper Clay.
Geologically, kaolin comes from decomposition of feldspar in soft, disintegrating granite, gneiss, and porphyritic rocks—granite rich in soda-feldspar yielding it in greatest abundance.
The term kaolin is derived from the Chinese word "Kau-ling", meaning high ridge, having reference to the locality from which the richest supplies were obtained.
