The black and white of casserole is only the difference between black glaze and white glaze, and there is no essential difference. They are all made of seasonal, clay and other materials. The pot of casserole becomes a glass body after high temperature firing, which can't adapt to the temperature difference well. When it is suddenly heated by cold, it will "catch a cold" and then break. Casserole has a certain "spirituality". Only by daily maintenance can it cook good dishes when it is used.

In other words, when we go to the market to choose a casserole, we don't care too much about its color. Be sure to see if the pottery in the casserole is good enough, and the pottery glaze on the surface must be bright and uniform. Only by using this pot can we conduct heat better. In addition, it is also necessary to pay attention to whether the overall structure of the casserole is reasonable, whether the appearance of the pot body is regular and round, whether the bottom of the pot can be placed smoothly, and whether the inner wall of the pot is smooth enough. After the casserole is bought back, it should be filled with water in time to test whether it leaks. If it leaks, it should be replaced immediately. Of course, there are also views that black casserole contains non-ferrous metals, and it is a psychological comfort to choose a white pot with better quality. However, some people are overly worried that monsters will constantly produce toxic and harmful substances when used, which is completely unfounded.

How to deal with the new pot before use?

First of all, be sure to clean it. It is suggested to wipe the inside and outside of the casserole with soft cloth and water to completely remove dust. Then soak in rice washing water for one night, and put more water, preferably over the surface of the casserole, so that the treated casserole will be very durable.

Secondly, cook a pot of porridge with it and "feed" it. Even the best casserole is made of mud. To put it bluntly, things made of clay are bound to have "eyes". A pot of porridge is cooked, and the porridge is sticky, so that we can put the "eyes" that can't be seen clearly with the naked eye in the pot and make a thorough repair. Where the porridge water can't pass, we can pour it with a spoon, then let it cool and pour it out overnight. In this way, the service life of the casserole will be extended. After completing this step, we can cook all kinds of delicious soups in casserole.

Just because the raw material of casserole is clay, no matter how good the casserole is, it must not be dry-burned, otherwise terrible events will happen.
