Why is bone china transparent? The reason why bone china has become a high-grade porcelain is that it has a series of characteristics that are different from ordinary ceramics. So why does bone china have these characteristics? The main reason lies in the raw materials. The color of porcelain itself mainly depends on chemical substances such as silicon oxide and calcium oxide. The higher the calcium oxide content, the better the color and whiteness.

Bone china added with animal bone meal has a large amount of calcium oxide source, so the color of the fired porcelain is milky white. In addition, because animal bone meal contains a certain amount of phosphorus, the bone china fired has a special luster, which is relatively transparent. When the bone powder content in bone china reaches a certain proportion, the quality of bone china will be greatly improved, and it will have very good luster and moisturizing. If you continue to improve, it will have the opposite effect, and the porcelain will become soft. Therefore, bone china is not the more bone powder content, the better, it has a degree.
