Is the casserole glazed or unglazed?

April 10, 2022

Casserole is a kind of ceramic product, which uses clay and sand as raw materials. In addition to the material, whether the casserole is glazed or not also needs to be considered. Ordinary casseroles are mainly clay and fired at high temperature. The inner layer of the casserole is glazed and sintered, so it is glazed, but it is also a casserole with or without glaze. Is it better to glaze the casserole or not?

1. The advantage of glazed casserole is that the glaze is less likely to crack after sintering, and the cleaning is more convenient. Don't worry about food residues entering the crevices of the clay. However, the disadvantage of glazed casseroles is the risk that heavy metals may exceed the standard, especially some inferior casseroles. The lead content in glaze may exceed the standard. Long term use will lead to the precipitation of heavy metals and affect people's health.

2. The advantage of unglazed casserole is that you don't have to worry about heavy metals, and compared with glazed casserole, the dishes baked in unglazed casserole taste better. However, its disadvantages are also obvious, that is, it is easy to crack without glazing, and cleaning residues and water may enter the internal cracks and affect normal use.

3. Generally speaking, glazed casserole is better than unglazed casserole.
