Most of them are OK. Many glassware can be heated in microwave oven, such as microcrystalline glass, titanium oxide crystalline glass and borosilicate glass. The glass material has stable physical and chemical properties and is very resistant to high temperature. It is very suitable for long-term use in microwave oven. However, glasses and milk bottles made of ordinary glass are only suitable for heating in the microwave oven for three minutes. If the time is too long, there is a risk of cracking Carved glass, reinforced glass and crystal glass products will burst when cooking oily food due to uneven thickness of materials, so they are not suitable for use in microwave ovens.
Do not use metal utensils
Because of the iron, aluminum, stainless steel, enamel and other utensils put into the oven, the microwave oven will generate electric sparks and reflect microwaves when heating, which will not only damage the oven body but also can not heat food. Microwave oven is a cooking appliance that uses food to absorb microwave energy in the microwave field to heat itself. （WeiBoLuKeYiYongBoLiWanMa）
