What are the differences between white China and bone China?

1. Raw material difference:

White porcelain: The main raw materials of white porcelain are kaolin and quartz and other mineral raw materials, and bone meal is not added in the production process. It has a relatively thick birthmass and a relatively hard texture.

Bone China: The raw material of bone China is porcelain clay, which is mixed with mineral raw materials such as bone meal and quartz. The high content of bone meal makes bone China thinner, lighter and more delicate in texture.

2. Appearance characteristics:

White porcelain: The surface of white porcelain is bright white, the glaze is smooth and uniform, the texture is relatively thick, the shape is diverse, but the overall is relatively simple.

Bone China: The surface color of bone China is usually milky white, light texture, and thin fetal material, so the shape is more rounded and smooth, and the light transmission is better, which can show a softer light effect.

3. Weight difference:

White porcelain: Due to the relatively thick fetal material of white porcelain, its weight is generally slightly heavier than that of bone China of the same size.

Bone China: Bone China is relatively light in overall weight because of its thin birthmass, which is lighter than white porcelain of the same size.

4. Differences in sound characteristics:

White porcelain: When two pieces of white porcelain collide, they usually emit a dull "ding" sound, and there is basically no echo.

Bone China: When two pieces of bone China collide, it will emit a crisp "clang" sound, and there is a clear echo. This is because the bone China is lighter and thinner, making the sound louder after the collision.

5. Production process difference:

White porcelain: The process of making white porcelain is relatively traditional, mainly including molding, drying, firing, glaze and other steps.

Bone China: The production of bone China requires a more complex process, especially in the batching and firing process need to strictly control the proportion of bone powder and temperature to ensure the quality and color of the product.

By means of weight assessment, shape observation, color discrimination and sound listening, white porcelain and bone China can be relatively accurately distinguished, which also helps consumers make the right choice when buying.
