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.
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.
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.
Pottery: glazed or not glazed. The surface
is slightly thick, and the air permeability is good. The utility model can be
used for tiles, flower pots, tea cans, etc.
Porcelain: glaze in general. The surface is
smooth and easy to clean, so it is very suitable for tableware and floors.
