The kiln company talks about the precautions of ceramic kiln burning

The kiln company talks about the precautions of ceramic kiln burning:

1. Burning kilns and cold kilns are too fast and the porcelain is easy to crack;

2. Insufficient oxidation time, foaming may occur when the kiln is burned too fast;

3. When the firepower of the kiln is uneven, it is easy to deform;

4. When the temperature in the kiln is uneven and overfire, the porcelain pieces swell;

5. When the burning method and flame properties are suitable, the porcelain surface is easy to change color and produce stains;

6. The cold kiln is too slow, and the cross-section of porcelain is often rough;

7. It should be too heavy too long when burning the flame, otherwise it is easy to commit smoking defects;

8. When burning large and thick-walled products, it is necessary to pay attention to the slow temperature rise during the ignition and baking stage, the oxygen should be cleared through oxygen, and the cooling stage should be extended appropriately;

9. In addition to controlling the appropriate content of carbon monoxide and the appropriate timing of reduction and recovery when burning certain colored glaze products, attention should be paid to controlling the content of free oxygen;

10. In addition to controlling the proper heating and holding time, it is advisable to use oxidizing flame for firing crystalline glaze.
