personalised ceramic mug
Excellent bone china is formed by adding a large amount of bovine bone powder with less impurities to the raw material with feldspar and scopole clay as the main raw material: because the raw material contains a large amount of bone powder, the clay becomes less viscous, Therefore, in the production process, special care must be taken in forming.
Firing
1. After forming and processing, it is sintered at the highest temperature of 1250 degrees. During the sintering process, the shrinkage of bone china is very large, so the finished product will shrink by 20% after kiln firing (generally porcelain shrinks by 7%), so the shape is easy to deform. The bowls must be placed on the special Kuang bowls for long-term cooking.
2. After that, the shape and size are checked. After grinding the surface, spray the glaze with a sprayer and enter the kiln to burn the glaze at 1150 degrees.
Coloring
The general coloring method is to paste transfer paper on the white finished product and fire it at 820 degrees.
