What is high temperature porcelain?
High-temperature porcelain refers to porcelain that has been fired above 1200 degrees. Because the higher the temperature, the greater the crystal density of the glaze, the higher the strength of the porcelain surface, the less likely to be scratched, the color is “white” and the white is not yellow, and it has the reputation of “white as jade”. Compared with low-temperature porcelain, the differences between the two are as follows:
1. Temperature: The firing temperature of high-temperature porcelain is above 1200 degrees; the firing temperature of medium-temperature porcelain is 1000-1150 degrees; the firing temperature of low-temperature porcelain is 700-900 degrees.
2. Color and luster: high-temperature porcelain has fuller, finer, and brighter color; medium-low-temperature porcelain has a contrasting color with wood.
3. Hand feeling: high temperature porcelain is lubricated and delicate; medium and low temperature porcelain is slightly rough.
4. Sound: High-temperature porcelain is crisp and crisp; medium and low-temperature porcelain is relatively low stuffiness.
5. Texture: high-temperature porcelain is firmer in hardness; medium-low-temperature porcelain is more fragile.
6. Water absorption: The most significant difference between high-temperature ceramics and medium and low-temperature ceramics is the water absorption. The water absorption rate of medium and low temperature ceramics is high, and the water absorption rate of high temperature ceramics is less than 0.2%. The product is easy to clean and will not absorb peculiar smell, and will not cause glaze cracks and partial water leakage. The water absorption rate of medium and low temperature ceramics is much higher than this standard, and it is easy to enter sewage. It is not easy to clean and will give off an unpleasant odor. Over time, cracks and water leakage will occur.
