Preparation of raw materials: take feldspar and guishi clay as the main raw materials, and add a large amount of beef bone powder with few impurities to the raw materials to make high-quality bone china.
Molding: The bone china cup is exquisite in material, fine in production and strict in standard. Its regularity, whiteness, transparency, thermal stability and other indicators all depend on its raw materials silicon oxide, aluminum oxide and calcium oxide. The higher the content of calcium oxide, when the content of bone powder reaches a certain proportion, the quality of porcelain will be greatly improved. , which is mainly reflected in the gloss of the container. However, if the content exceeds a certain proportion, the composition of the clay is relatively reduced, the porcelain becomes too soft, and the more difficult it is in the production process, so it is more precious.
Coloring: The usual coloring method is to place the transfer paper on the finished white texture and then fire it at 820°C.
Inspection: All trips are strictly inspected, qualified products are sent to the next trip, and then the package is shipped to the factory. Compared with ordinary porcelain cups, bone china cups not only have a beautiful and delicate appearance, but are well-deserved green and healthy ceramics.
