The Main Difference Between Pottery and Porcelain.

Pottery and porcelain are two entirely different things. In short, Pottery is a clay calcined at low temperature, Porcelain is a clay fired at high temperature.

 

Raw material

Pottery: clay, the ordinary clay.

Porcelain: namely clay kaolin.

Pottery: About 800-900 degrees Celsius, generally not more than 1100 degrees Celsius.

Porcelain: 1200-1300 degrees, and some even up to 1400 degrees Celsius.

 

Porosity

Pottery: the porosity is about 12%-38%. The permeability is good and the texture is loose.

Porcelain: porosity of about 2%-8%, poor permeability, dense texture.

Pottery: modeling is generally simple, looks rough, primitive simplicity.

Porcelain: exquisite modelling, looks delicate, bright and clean, elegant.
