Semia porțelanului este aproape de cea a porțelanului, dar mai are 3-5% absorbtia apei dupa ardere (portelan adevarat, absorbția de apă este mai jos 0.5%), deci performanța sa nu este la fel de bună ca cea a porțelanului, which is better than that of fine ceramics. Porcelain is a higher stage in the development of ceramics. It is characterized by complete sintering and vitrification of the body, so it is very dense, and has no permeability to liquid and gas.

The difference between pottery and porcelain lies in the difference of material soil and temperature. On the basis of the temperature of pottery making, adding fire and heating, pottery becomes porcelain. The firing temperature of pottery is 800-1000 Pânză simplă, and that of porcelain is 1300-1400 Pânză simplă. There are many kinds of ceramic products, the chemical composition between them. Mineral composition, physical properties, and manufacturing methods are often close to each other without obvious boundaries, but there are great differences [...]
