The blank of semi porcelain is close to that of porcelain, but it still has 3-5% water absorption after firing (true porcelain, water absorption is below 0.5%), so its performance is not as good as that of porcelain, 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.

La differenza tra ceramica e porcellana sta nella differenza del terreno materiale e della temperatura. Sulla base della temperatura di fabbricazione della ceramica, aggiungendo fuoco e riscaldamento, la ceramica diventa porcellana. La temperatura di cottura della ceramica è 800-1000 ℃, e quello di porcellana lo è 1300-1400 ℃. 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 [...]
