Bone china, the reason why it is called bone china, has something to do with the raw materials used to make it. The raw materials of bone china are pottery raw materials and herbivore bone meal (beef bone meal is the best after evaluation). The content of bone meal above 25% can be called bone china.
What are the characteristics of bone china, and what are these characteristics? Let's listen to bone china manufacturers one by one.
The color and luster of bone china
The color and luster of bone china is a major feature. Because the major types of porcelain on the market are all pure white, which can also be described as bluish white, while the color of bone china is slightly yellow. The bone meal content shows how yellow it is. The higher the bone meal content of bone china, the more milky white the color will be. On the contrary, the lower the bone meal content, the more obvious the yellow color will be.
The permeability of bone china
We know that the exquisite porcelain and eggshell porcelain made in my country are really thin, and of course they are transparent. Many people should have seen this kind of lampshade in a certain treasure, which is very elegant. Permeable types of porcelain include, in addition to bone china, pearl porcelain, shell porcelain, white porcelain, etc., because porcelain is transparent and transparent only when its thickness is thin enough to a certain extent. But bone china is different from other types of porcelain. Its permeability is overall transparency (here bone china refers to high-quality bone china), and the light transmission (white light) does not change the light color (the transmitted light is still white light). Its permeability becomes more transparent as the bone meal content increases. It is also transparent because of its raw material, natural bone meal.
The sound of bone china
When bone china is tapped or lightly touched, it makes a sound similar to temple bells, very crisp and pleasant, with a long echo time. The sound of other well-fired porcelain is relatively light and crisp, but the duration is short. You can tap it lightly without the feeling of a bell. As for the dull percussion sound, it is not recommended to buy (not fully fired).
