Ceramic Mug Group, The formation of bone china relies mainly on silicon oxide, aluminum oxide and calcium oxide, of which the higher the calcium oxide content, the better the color. In nature, there are not many sources of calcium oxide, so animal bone meal is chosen as the source of calcium oxide.
In fact, the so-called bone china is a bone china product made from the ashes of herbivorous animals (mainly Ca3(PO4)2) as raw material, mixed with high-quality kaolin, quartz and other auxiliary materials, and glazed and fired at 1280℃. Generally speaking, the raw material to add 25% of the bone powder can be called bone china, but today the world recognized the texture of the best bone china for 45% -51% of the content of bone powder, and to the cattle bone is good.
Its production process through to the grouting, mold pressing embryo, gypsum mold dehydration, as well as the initial firing, glaze firing, paste flower paper baking and other processes, the high temperature firing, become high whiteness, high transparency, fine porcelain porcelain. Bone china in the firing process, the degree of regularity, whiteness, transparency, thermal stability and other physical and chemical indicators are extremely high requirements, resulting in a high rate of scrap. Because of the material is exquisite, fine production, strict standards, so the value is higher than other kinds of porcelain.
Unique firing process and the addition of bone carbon, so that the impurities in the porcelain clay is eliminated, bone china appears more white, delicate, translucent, lightweight, very few defects, and thinner than the general porcelain, a special sense of cleanliness in the visual sense of the strength of higher than the general porcelain, is twice as much as the daily use of porcelain. The higher the content of bone meal, the clay content is relatively lower, in the production process, the easier it is to burn crack, in the molding requires higher technology, increasing the difficulty of firing, so it is more precious.
Some people have done this experiment, put 4 bone china cup pad in a Rolls-Royce under the wheels, these 4 crystalline cups can actually be competent to support the weight of the caravan!
High-grade porcelain and bone china similar to the shell porcelain and pearl porcelain, because the cost is too high almost no industrial production, so bone china is recognized as the world's most high-grade porcelain.
