Hello, the microwave oven can be placed on a stainless steel tabletop, but stainless steel tableware cannot be placed in the microwave oven.

1. Do not put eggs in the microwave oven because they will expand when heated and produce a lot of water vapor, which may cause an explosion.

2. Do not place metal tableware, as it may cause spontaneous combustion of metal tableware.

3. Foods such as fruits must not be heated in a microwave oven.

4. Paper products can be ignited at any time if placed inside. Milk cartons, plastic containers, etc. cannot be placed inside for heating.
