What's the difference between ceramics, white porcelain and bone porcelain?

There are three kinds of porcelain on the market now: white porcelain is also called shell porcelain, bone porcelain and new bone porcelain (excluding bone powder), among which white porcelain is a traditional craft product of Jingdezhen, which is difficult to form and has low success rate. The quality of general products is difficult to compare with bone China, but the cost of high-grade products is relatively high. Therefore, due to some cost considerations, there is a so-called new bone China on the market, which is made by adding some chemical raw materials without adding bone powder. Comparing the weights of white porcelain, new bone porcelain and bone porcelain, the same porcelain type is generally the heaviest, followed by new bone porcelain and the lightest. Shape discrimination, because of the process and raw materials, bone China is thinner than white porcelain and new bone China, with more rounded and smooth shape and better light transmission. High-grade bone China has fine and dense porcelain, smooth surface, bright glaze color and natural milky white. High-grade bone China is relatively light; After the two bowls collided, the sound was as clear as ringing a bell, and the sound "clanked" and the echo time was longer.
