In addition to stainless steel utensils, metal containers such as iron, aluminum and enamel cannot be heated in the microwave oven. The utensils made of these materials not only have poor heating effect, but also may damage the life of microwave ovens.
Microwave oven safety accident:
1, liquid overheating. When microwave heating, because water does not flow, but the temperature rises, it may "not open" when it exceeds the boiling point, leading to overheating. At this time, as long as the water is slightly disturbed, it will boil violently, which is prone to scald accidents. The cleaner the container and the cleaner the water, the greater the possibility of occurrence.
2. The egg exploded. The microwave oven can't heat the eggs, because overheating inside the eggs will generate more pressure, which may explode if it is released due to external interference.
