Porcelain describes ceramics with a white body fired at a high temperature.
Hard-paste porcelain, also known as true porcelain, is fired at temperatures up to 1450ºC. It has a vitrified (glassy) appearance and is hard, strong and non-porous. It can be used to make very delicate objects which may be thin walled and translucent. The glaze on hard-paste porcelain is fused to the body by the high firing temperature. Exposed or broken edges can be very smooth and almost glassy in texture. Hard-paste porcelain is made from china stone and/or china clay (kaolin).
