Can stainless steel insulated lunch boxes be heated in a microwave oven?

2021-08-25

This is unacceptable and will cause a fire hazard.
Do not use metal containers in the microwave oven, otherwise it will affect the heating time and cause the microwave to contact the metal to produce sparks, which will be dangerous, and the magnetron will be damaged in severe cases.

The stainless steel lunch box will not explode when placed in the microwave oven, but it will produce electric sparks. Because the stainless steel utensils are put into the microwave, the microwave cannot penetrate the stainless steel, and it will be reflected back on the stainless steel, causing electric sparks and reflected microwaves, which damage the furnace body and cannot heat the food. . The microwave oven cannot be idling, because the microwave has no food to absorb the microwave, and idling will damage the microwave oven.
