The function of bone meal components in bone China tableware

The bone meal components in bone China tableware mainly have the following functions:

Increasing hardness and strength: The bone meal component can enhance the hardness and light transmittance of porcelain, and its strength is higher than that of ordinary porcelain. Therefore, bone China can be made thinner than ordinary porcelain. For instance, 40% bone meal products have 2 to 3 times stronger impact resistance than ordinary porcelain and are suitable for making ultra-thin cup walls.

Improving light transmittance: The content of bone meal affects the light transmittance of porcelain. The bone meal content of high-quality bone China is usually between 30% and 50%. Internationally certified bone China must contain at least 25% animal bone meal, and high-end products can reach 45% to 50%. During the test, the light transmittance can be observed. The higher the bone meal content, the more uniform the light transmittance. Porcelain containing more than 35% bone meal is milky white and gives a metallic echo when struck. Align bone China with the light source, and high-quality products will show a pink color when illuminated.

Enhancing heat preservation: Compared with traditional porcelain, bone China has better heat preservation, providing a better experience when drinking coffee or making tea.

Optimizing appearance and texture: The bone meal composition gives bone China a natural milky white color unique to natural bone meal. The porcelain is fine, the whiteness is soft, the shape is elegant and beautiful, and the color surface is lustrous and bright, giving people a sense of nobility and elegance.
