Microwave oven is one of the necessary household appliances in children's life. Convenient and quick, greatly reducing their housework burden. The safer materials for microwave ovens are as follows: 1. Glass materials: including utensils made of borosilicate glass, glass-ceramics and titanium oxide crystal glass, because they have good microwave penetration and physical and chemical properties.

Stable and high temperature resistant, suitable for long-term use in microwave ovens.

However, it should be noted that glasses, baby bottles and baby bottles made of ordinary glass are only suitable for heating in the microwave oven for a short time, about 3 minutes.

If the heating time is long,

It is easy to break down. Carved glass, tempered glass, crystal glass and other materials are oily because of their uneven thickness.

Things will explode when used, so they are not suitable for use in microwave ovens.

2. Ceramic materials: there are heat-resistant ceramics and ordinary ceramics. Pots, plates and other utensils made of heat-resistant ceramics are suitable for long-term use in microwave ovens.

Ordinary ceramic utensils can only be heated for a short time. In particular, it should be reminded that ceramic utensils containing gold and silver wires will generate sparks when used in microwave ovens, so they are not suitable for use.

3. Plastic material: all kinds of utensils made of polypropylene, polypropylene resin, composite polypropylene, polysulfone, PET resin, polyester, etc. are resistant to high temperature and can be used for microwave heating.
