The production process of bone china cup

The production process of bone china cups The so-called bone china is a ceramic product made from the bone ashes of herbivores, mixed with high-quality kaolin, quartz and other auxiliary materials, and fired at 1280 ℃. The formation of bone china mainly relies on silicon oxide, aluminum oxide and calcium oxide. The higher the content of calcium oxide, 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. Generally speaking, adding 25% of bone powder to the raw material can be called bone china, but the bone china with the best texture recognized in the world today has a bone powder content of 45%-51%, and bovine bone is the best one. The production process goes through the processes of grouting, mould pressing embryo, plaster mould dehydration, as well as initial firing, glazing firing, decal baking and other processes. After high temperature firing, it becomes a porcelain with high whiteness, high transparency and fine porcelain. During the firing process of bone china, its regularity, whiteness, transparency, thermal stability and other physical and chemical indicators are extremely high, so the rejection rate is very high. Due to the exquisite materials, fine production, and strict standards, the value is higher than other types of porcelain. The unique firing process and the addition of bone carbon eliminate the impurities in the porcelain white porcelin dinnerware clay. The bone china appears whiter, finer, transparent, lighter, less flawed, and thinner than ordinary porcelain. It has a special visual It has a sense of cleanliness, and its strength is higher than that of ordinary porcelain white porcelin dinnerware and twice that of daily-use porcelain. The higher the content of bone meal, the lower the composition of the clay, the easier it is to burn during the production process, and the higher the forming technology is required, which increases the difficulty of firing, so it is more precious.
