Why do ceramic cups smell?

March 20, 2022

The smell of the ceramic cup suggests bad quality. If the ceramic cup is made of inferior colored glaze, it will give off a bad smell after pouring hot water. As we all know, all ceramic products need to be fired at high temperature, but the kiln temperature can vary during firing. According to the different temperature, ceramic cup can be divided into low temperature ceramic cup, medium temperature ceramic cup and high temperature ceramic cup.
