1, glass bowl

Generally, glass will not block the passage of microwaves and will not generate heat, so glass can enter the microwave oven.

Carved glass, tempered glass and crystal glass products will burst when cooking oily food due to uneven thickness of materials, and are not suitable for use in microwave ovens.

Generally speaking, ceramic products can be heated by microwave, but white porcelain (that is, no colored glaze) is needed.

Coloured glaze and gold powder belong to metals and cannot be heated in the microwave oven.

3.PP plastic bowl

Polypropylene (PP) is heat-resistant and can withstand the high temperature of about 200℃, so it can be heated by microwave.

Extended data:

The most important thing to judge whether the container is put into the microwave oven is to master three elements: the microwave oven has strong penetration, high temperature resistance and meets the food hygiene requirements.

Tableware made of the following materials is not suitable for microwave ovens:

1, plastic tableware with poor heat resistance

Ordinary plastic tableware has poor heat resistance and cannot be used as a microwave cooker.

2. Glass tableware with poor heat resistance

When cooking food with oil, the temperature may be very high, which may easily break the glass tableware, so heat-resistant glass tableware cannot be used.

3. Microwave can't penetrate metal tableware.

Aluminum pot, enamel pots, stainless steel pot and other metal tableware can't be penetrated by microwaves, and the metal will collide with the inner wall of the furnace and can't be used.

4. Lacquer tableware

The paint on lacquerware may peel off and melt after being heated, resulting in harmful substances, and the tableware may also crack. Eating heated food is also unhealthy.
