Comparison of the main differences between bone china and ceramic

The main ingredient in bone china is high quality natural bone meal. The manufacturing method is to add more than 30% herbivorous bone meal (the ingredient is tricalcium phosphate) to china clay. The finished bone china has a light, compact, and hard texture (twice as much as everyday porcelain) that is not easy to carry and break, and has moderate permeability. Lightness, heat protection and color become the unique natural milky white of natural bone meal. Below these, the bone meal content is more than 40% and the color of the device is a milky white. It is a high quality bone china.

Among them, bone meal is more than 40%, and the color of the utensils is milky white, which is high quality bone china.

      During the firing process of ceramic tableware, its regularity, whiteness, transparency, thermal stability and other physical and chemical indices must be extremely high, so that the reject rate is very high. Because of the exquisite materials, fine production and strict standards, the value is higher than other types of porcelain. The unique firing process and the addition of bone charcoal remove the impurities in the china clay. The bone china appears whiter, finer, more transparent, lighter, less flawed and thinner than ordinary porcelain. It has special visual cleaning. Sense and strength are higher than ordinary porcelain and twice as high as porcelain for everyday use. The higher the bone meal content, the lower the composition of the clay, the easier it is to burn during the production process, and it requires higher technology in molding, which increases the difficulty of burning and is therefore more valuable.
