Bone China, also known as bone China, is a kind of porcelain made of animal bone charcoal, clay, timely and feldspar, which is sintered by high-temperature vegetarian firing and low-temperature grapefruit firing. It is an environmentally friendly green consumer product. The main components of ceramics are kaolin, clay, porcelain stone and porcelain clay. Compared with ceramics, bone China is whiter, more delicate, more transparent and lighter. Moreover, the thermal insulation effect of bone China is better than that of ceramics.
Bone China is whiter than ceramics, with better light transmittance, and looks brighter and more pure white as a whole. It's a little dark and a little green. Ordinary ceramics only need natural clay and mineral materials, while bone China needs to add no less than 25% bone powder on this basis, and cow bone powder is often used. Bone China is thinner than ceramics, its light transmittance is better than ceramics, and ceramics are almost opaque. Bone China is tough and wear-resistant, not easy to wear and break, and its hardness is twice that of ceramics, so generally speaking, bone China bowls are healthier than ceramic bowls.
