Although ceramic tableware can be used in cold storage and freezing room, it will shorten its service life and be easy to crack. It is best to use stainless steel tableware or plastic food lunch box.
1. crockery plates will not be damaged by freezing in the emergency freezing room. At least once or twice, it will not be damaged by freezing, but the porcelain things are frozen rapidly. Due to the effect of thermal expansion and cold contraction, its internal structure will change, affecting its strength and service life. But once frozen, it won't be damaged. Unless containers like other shapes are cracked by frozen liquid.
2. This will shorten the service life. It is not recommended to put it in the refrigerator often. Porcelain tableware can be stored or frozen, but it will affect the service life of tableware and easily lead to tableware cracking.
3. Ordinary ceramic tableware is made of ordinary ceramic materials with great brittleness. Therefore, if the tableware is refrigerated or frozen, do not put it into hot water immediately. On the contrary, if the tableware is cooked at high temperature, do not put it into ice water immediately, so as to avoid cracking due to sudden heat or cold.
4. Ceramic tableware is the tableware we use more. We often use it to contain food, soup, drinks, fruits, etc. tableware can be refrigerated, frozen or boiled at high temperature. However, it cannot be used by sudden cooling or sudden heating. Of course, the selection of tableware should also pay attention to the problem of excessive heavy metals.
