New bone China: New bone China is usually not added to the name. Its essence is only a kind of white porcelain. By adding calcium oxide similar to mineralizer and bone meal to the porcelain blank, it has an impact on the firing temperature, deformation, water absorption, transmittance and other aspects of traditional porcelain. A new material similar to bone porcelain in appearance quality. As a result, smart manufacturers have given the name of new bone china.
