Precautions for using the casserole:

1. Heat it gradually and do not burn it suddenly on a high fire to avoid swelling and cracking.

2. After cooking the food, use wood chips to support the casserole when it is removed from the fire, so that it can dissipate heat evenly and cool slowly to avoid shrinkage and cracking. You can also make an iron ring according to the size of the casserole. When the casserole is removed from the fire, place it on the iron ring so that the bottom does not directly touch the ground and is suspended in the air to naturally cool down, which can make the casserole last longer.

3. Newly bought casseroles often leak. This is because there are many blisters. When a new pot is used for the first time, it is best to make noodle soup or porridge. After eating, put the casserole on the stove without washing the pot, so that the batter in the pot will dry up and block those tiny blisters on the pot wall. Wash.
