Chemical glaze water is dyed with industrial pigments and needs to be fired at low temperature with "oxidation flame" to become porcelain. Mineral glaze water takes the high-purity "iron element" in minerals as the coloring condition, and porcelain needs "reducing flame" high temperature firing. Mineral glaze water is a kind of glaze different from binary formula gray glaze and unitary formula soil glaze. It is a glaze made of many natural materials or simple synthetic materials.

Ru kiln fired by chemical glaze water has the characteristics of "simple process", "high yield" and "ultra-low cost", which makes porcelain fired by chemical glaze water have the conditions for profiteering.

Porcelain fired by mineral glaze water has the characteristics of "complex technology", "low yield" and "high cost", which makes porcelain fired by mineral glaze water have high firing difficulty and risk.

The same is as follows:

There are many kinds of glazes, which can be divided into lime glaze, feldspar glaze, lead glaze, zirconium glaze, boron glaze, lead-boron glaze, salt glaze and earth glaze. According to the appearance, it can be divided into transparent glaze, opaque glaze, colored glaze, crystalline glaze, Jinsha glaze, matte glaze and broken glaze. Coloured glaze has various colors, including red, yellow, blue, white, black, blue and white.

Part of the raw materials in the glaze are frit, which is called frit glaze when it is finely ground into glaze slurry. What doesn't need frit is raw glaze or raw glaze. According to the melting temperature, glazes can be divided into high-temperature glazes (>: 1250℃), medium-temperature glazes (1100 ~1250℃) and low-temperature glazes (

According to the conductivity, it can be divided into ordinary glaze and semiconductor glaze. Glaze paste is usually made of natural mineral raw materials (such as feldspar, calcite, Yingshi, talc, kaolin, etc.). ) and chemical raw materials are ground according to a certain proportion.
