What will happen if the ceramic is burnt too far?

Excessive firing defects of ceramics will make the porcelain body fragile and reduce its hardness.

1. Fragile porcelain body: Excessive firing will make the gas in the porcelain body expand, leading to problems such as cracking and cracking, while firing defects will increase the pores in the porcelain body, making the porcelain body fragile and difficult to bear external forces.

2. Hardness decrease: Excessive fire or firing defects will make the crystals in the porcelain blank rough and decrease the hardness of the porcelain blank.
