The ceramic white tire is a glazed porcelain that has been burned once but has not yet been baked.

Porcelain production process:

1: mud tire: the billet is subjected to grouting, or the billet is subjected to pressure filtration dewatering, mud-refining, and roll forming. The mud of the porcelain is first made, after 100 to 200 degrees of drying, after manual finishing. Glaze. The glaze is used in the form of glaze slurry. There are three ways to apply glaze: spray, pouring, dip, depending on the type of the device; after glazing, it needs to be dried again, and the drying temperature is generally 80-120 degrees. The glazed body is called a glaze.

2: White tire: The glaze tire is burned at about 1300 degrees, and the qualified product from the kiln is white tire. The white tire already has the function of using porcelain, and the rest is to decorate and decorate. It should be noted that some high-grade porcelains are first decaled, colored on the mud, and then burned, called the underglaze color; or after applying a layer of glaze, the applique is colored, and then the glaze is applied. For the glaze.

3: The decoration on the white tire is traditionally used for decaling or painting with finished flower paper. Then 800-900 degrees of roasted flowers, the finished product. Some high-end products have to be decorated once again. For example, the technique of sheet metal is to make some very convex decorations in the porcelain part, and finally to burn the third temperature at a lower temperature (500-600 degrees).

Underglaze color is painted on the dried mud tire (printing) and then applied to the surface glaze (transparent glaze or matt glaze) once, because the ceramic tire must be sintered, so the lowest firing temperature is also About 1200 degrees.

The glaze is divided into low temperature and high temperature, and the main factor for selecting the glaze is matching with the porcelain tire. Generally, the temperature of the tires is lower, and the glaze with a lower temperature is generally required. The bone china is also usually equipped with a low temperature glaze, and the ordinary high white porcelain needs a high temperature glaze. ,
