Underglaze color is a kind of porcelain glaze decoration, also known as "kiln color". Underglaze color is one of the main decorative means of ceramics. It uses pigments to draw various decorative patterns on the green body (i.e. semi-finished product) after molding and drying, and then applies white transparent glaze or other light colored glaze, which is fired at one time. After firing, the pattern is covered by a layer of transparent glaze film, and the surface is bright, soft, smooth, non protruding and crystal clear.
1. Good thermal stability
Under glaze ceramic tableware often needs to put some high-temperature food, and sometimes some frozen food. The sharp change of temperature will not lead to ceramic cracking, which is hundreds of times more than glass products. Because the heat conduction is slow, you won't feel very hot when you pick up the tableware.
2. Chemical stability
Acid and alkali resistance, not easy to react with food or water, which is the advantage of other metal tableware, such as stainless steel and iron. In addition, it is corrosion-resistant and does not rust.
3. Easy to clean
Because the surface of daily-use ceramics is smooth and easy to clean, many stains can be washed off with water.
4. Low water absorption
There are few ceramic holes, which can be sealed with a cover after storage to prevent water evaporation and reduce the invasion of external bacteria.
5. Colorful paintings.
Painted porcelain, or various flower faces, are very popular because they are beautiful and increase people's appetite.
