The ceramic cup is mainly made of kaolin ceramics, which is a kind of clay mainly made of kaolinite. Pure kaolin is dense or loose, and its appearance is white and light gray. Now ceramic cups are more and more popular in the market, and many people are excited by the beauty of their ceramic cups. At the same time, it seems that we have neglected some small knowledge in the production, such as: Is there any glaze on the inner wall of the ceramic cup?

2. The glaze on the inner wall of the ceramic cup mainly plays the role of increasing the aesthetic feeling of ceramic tiles. At the same time, glaze is a very dense material, which can play a very good antifouling effect and protect ceramics.

Drinking liquid containing chemical substances will be harmful to human health.
