1. The color of bone china
Because bone china contains bone powder, the porcelain itself is a natural milky white color, which is a bit yellowish in popular words. This feature cannot be imitated by any other porcelain species. The most important thing on the market is now. Several types of porcelain, such as white porcelain, shell porcelain, and pearl porcelain are all pure white. We can describe the pure white as bluish-white. Secondly, they are all bone china. The degree of yellowing can be seen. For bone china, the content of bone powder is an important technical indicator for distinguishing the grade of bone china. The more bone powder, the more high-end bone china, and the more the color of bone china tends to be milky white. On the contrary, if the bone meal content is low, the yellowness of bone china itself is very obvious.
2. Permeability of bone china
Because of its own formulation, bone china has an important external feature that is permeability, but this feature is not exclusive to bone china. As long as the shell porcelain, white porcelain, and pearl porcelain on the market are made thinner, there is still a common feature. Permeability, but there is a difference between bone china and their permeability. For the majority of customers and friends, it is very convenient to see the difference in permeability is to look at the bowl-shaped container and buckle the bowls of different porcelains. The light bulbs have different permeability effects. The high-grade bone china with high bone powder content is overall transparent, and the bone china with low bone powder content is obviously different from other porcelains in the permeability effect.
3. The sound of bone china
Because of the recipe of bone china, another important external feature is the sound made when bone china collides. Put two high-grade bone china bowls on your flat hands to collide. Note that bone china is high temperature. The hardness of the fired porcelain is very high, so there will be no damage in such a collision. Please rest assured that you can make a little harder collision. After the collision of high-grade bone china, the output will be the same as the bell. The sound is crisp and clanging, and there is an echo, and the echo time is longer, while the other types of porcelain make a dull ding, and there is basically no echo.
4. Touch the bottom of the bowl
The bottom of a finely crafted bone china bowl needs to be polished twice to prevent slippage and scratches on the tabletop. This is to test the craftsmanship of a porcelain from the details.
