What is Porcelain and How is it Made?
Porcelain is a type of ceramic material that is made from a combination of clay, feldspar, and quartz. The process of making porcelain involves mixing these materials together with water to create a workable paste, which is then shaped into the desired form. The shaped porcelain is then fired at a high temperature, typically between 1200 and 1400 degrees Celsius, to create a hard, non-porous, and translucent material.
