Various Kind of Clay

Clay is a material that elastic to form in damp condition and contains silica, aluminum, and water. It will change into ceramic after firing.
Based on firing finished products, there are three kinds of clay : earthenware, stoneware and porcelain.

Earthenware

Earthenware has maximum temperature for 900 Celcius degree and the fired products are pottery and terracotta. Pottery goes to pots, vessels and tableware, whereas terracotta goes to sculpture and relief. This clay mostly red in color after firing.

Stoneware

The temperature of stoneware clay can reach 1250 Celcius degree. The character of this clay after firing (become ceramics) is not easy for water to penetrate, that is why it is most use for industry. White and brown are the most common color.

Porcelain

Porcelain is not elastic and not easy to form, but the master can do it. It is white in color and translucent if the thickness is very thin. Porcelain has the highest in temperature, it can reach 1300 Celcius degree.
