Porcelain is the most vitreous of the types of pottery and, when immersed in water, absorbs less than 1% by weight of water. When thin, porcelain will often be translucent. It is the strongest of all clay bodies, but also the most brittle. While it is possible to formulate a porcelain clay body that fires at low temperature, most are fired to 2200-2500 degrees Fahrenheit.

| porcelain |
A clay body which, when fired, becomes very mature and usually translucent. Porcelain is normally quite white and fires to a very smooth pleasant surface. Porcelain clays lack iron impurities and are ground to very fine particle sizes. Plastic porcelain clays tend to be shorter than their stoneware or earthenware counterparts. Porcelain casting slips achieve the whitest and most translucent results.
