Casserole is made of timely and other raw materials, which has the characteristics of slow heat transfer and high temperature resistance. If it is used to cook hot pot, it will lead to problems such as insufficient heat. Casserole can't be cooked with open fire for a long time. It's better to heat it slowly with electric heating. Cooking soup in casserole can keep the temperature constant for a long time and reduce the loss of heat.

. Casserole is made by mixing seasonal, feldspar, clay and other raw materials in a certain proportion, and then firing at high temperature. Casserole has good ventilation, strong adsorption and slow heat transfer, but it is uniform and slow in heat dissipation. Therefore, using casserole to stew soup can keep a certain temperature for a long time and greatly reduce the heat loss.
