How To Distinguish Between Pottery And Porcelain?

Nov. 13, 2019

Pottery is a general term for pottery and porcelain. Simply put, a vessel made of clay and baked in a fire becomes pottery. Basically all early human civilizations made pottery. In the Han Dynasty, Chinese potters raised the temperature of their kilns and produced ware that was harder and finer than pottery.

The main components of porcelain and pottery are similar, both aluminum oxide and silicon dioxide. As everyone knows, sand is silicon dioxide. Sand is silicon dioxide. When you melt sand and then cool it, you have the glass. The difference between porcelain and pottery is that the temperature of the porcelain is high during firing, the raw material is completely melted, and the temperature of the pottery is low, only partially melted. In short, porcelain is more like glass than pottery.

1. Look. Porcelain is more lustrous than pottery. For light sources, thinner porcelain is translucent and pottery is opaque. Look at the place where the bottom foot has no glaze, the porcelain is delicate, and the pottery has a distinct graininess.

2. Touch. Porcelain feels smooth and delicate; pottery is a little rough.

3. Listen. If the bottom is flat, you have to pinch it with your thumb and forefinger to reduce the contact area as much as possible, and then hit the body with your fingernails. The sharp voice is porcelain, the low voice is pottery. Be careful! Whether it's porcelain or pottery, there are echoes when it's knocked. If it is very short, similar to the sound of knocking on a board, then this ceramic is likely to have hidden damage, which will crack when heated. Do not buy it
