The formation of bone China mainly depends on silica, alumina 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.
Features:
1 Beauty of appearance: the porcelain is delicate and transparent, the shape is beautiful and generous, the color surface is moist and bright, and the flower surface is colorful.
High-grade: produced in Britain, it has long been a special porcelain for the British royal family and nobles. It is the only recognized high-grade porcelain species in the world, which has dual values of use and art, is a symbol of rights and status, and is known as the king of porcelain.
Health care products: the main choice for making bone China comes from animal bone charcoal, which will not contain excessive lead and cadmium in other porcelain products.
Process: secondary firing, complicated process, only produced in Britain, China, Japan, Germany, Russia and Thailand.
Extended data:
The new and old are:
The so-called new bone porcelain is essentially just a kind of white porcelain. By adding calcium oxide, a mineralizer similar to bone powder, to the porcelain blank, the firing temperature, deformation, water absorption and light transmittance of traditional porcelain are affected, and a new material with similar appearance quality to bone porcelain is formed. Although it seems to be as white and delicate as bone China, it is very different from bone China in essence and material.
Many businesses will deliberately omit the word "new". It seems that a set of bone China products can be done as long as 1000-2000 yuan, but buyers have bought new bone China.
It's not that the new bone China is not good. It all depends on personal preference. However, the word difference is completely different for people who want to buy bone China.
The relationship between tableware and diet;
The advantage of plastic tableware is that it is light in weight and not fragile, but it contains heavy metal substances harmful to human body, which will affect human health after release; Glass tableware has high hardness and is easy to clean, but crystal glass tableware is a high-risk lead pollution source and is not suitable for wine, because it will dissolve lead and affect human health.
Ceramic products are delicate, smooth and easy to clean, but ordinary ceramics also contain some heavy metals, and the brighter the color, the easier it is to affect health. Bone China tableware is the only recognized high-grade tableware in the world. It has various shapes, takes animal bone powder as the main raw material, does not contain heavy metals such as money and cadmium, and is easy to clean.
