by:Two Eight     2021-08-28
manufacturing process 1. The ceramic tableware with excellent raw materials is formed by adding a large amount of bovine bone powder with less impurities to the raw materials with feldspar and scopole clay as the main raw materials: because the raw materials contain a large amount of bone powder, Makes the viscosity of the soil smaller, so in the production process, the forming and production need to be extra careful. 2. Firing ① After forming and processing, it is fired at the highest temperature of 1250 degrees Celsius. During the firing process, the shrinkage of ceramic tableware is very large, so the finished product will shrink by 20% after kiln firing, so the shape is easy to deform. Cook for a long time on the special Kuang bowl. ②Then, check the shape, curvature and size. After grinding the surface, spray the glaze with a sprayer and enter the kiln to burn the glaze at 1150 degrees Celsius. 3. Coloring The general coloring method is to paste transfer paper on the white finished product and burn it at 820 degrees Celsius. 4. Inspection All trips are strictly inspected, and qualified products will be sent to the next trip and made into finished products.
