Have you painted the glaze in the casserole?

No, the glaze is made by coating a layer of glass glaze on the surface of the casserole and then firing it at high temperature. The function of glaze is to enhance the durability of casserole, prevent the surface of casserole from being eroded and worn by food, and make casserole easier to clean and maintain. Therefore, the glaze of casserole is a ceramic surface treatment technology, not a coating. Casserole glaze is a glassy substance made of natural minerals such as timely, feldspar and clay, which is fired at high temperature.
