Is the casserole ceramic?

The traditional casserole is a kind of pottery. Traditional casserole is a ceramic product made of raw materials that are difficult to transfer heat, such as seasonable, feldspar and clay. Fired at high temperature, it has the characteristics of air permeability, adsorption, uniform heat transfer and slow heat dissipation.

Tao is the greatest invention of human development. According to archaeological findings, as early as the Neolithic Age, people began to use sand-mixed pottery (similar to casserole). Sand-mixed pottery is a common kind of pottery in Neolithic Age, mainly red pottery and gray pottery. After the improvement of past dynasties, sand pottery has evolved into the casserole we use now.
