The fireproof cookware from the company SP Tableware is a cooking utensil particularly resistant to sudden temperature changes. It does not crack, wear out, or break easily. It can be used in a conventional oven, microwave oven, as well as in the freezer, refrigerator, and dishwasher. It is made of ceramic material, which makes the utensil particularly resistant to high temperatures. Fireproof ceramic utensils distribute temperature more slowly and require more cooking time.
