On bone porcelain, jade porcelain, celadon and white porcelain cups

The difference between bone porcelain, celadon, white porcelain and jade porcelain is mainly in raw materials and firing technology. Bone China, as you already know, celadon contains iron oxide, which is fired in reducing flame and gives off a blue tone. The raw materials of white porcelain are required to have low iron content, burnt into oxide flame, and the color tone is white, which belongs to ordinary porcelain. As for jade porcelain, it is hard to say. Ordinary porcelain produced by our original factory is called jade porcelain because of its high transparency and whiteness. Bone China is of a higher grade. Celadon and white porcelain depend on your personal preference. Generally, bone China cups cost more than ten or twenty yuan in the market, and some are more expensive, all of which are bone China (high whiteness of bone China, light and thin porcelain tire, good transparency and delicate glaze color). The so-called harm to human body refers to the dissolution of lead and cadmium on the surface of ceramic products. At present, most bone China uses lead-free glaze, and the dissolution of lead and cadmium will not exceed the standard. You'd better have a cup without a picture when you buy it.
