Can iron dishes be heated in a microwave oven?
Microwave is a kind of electromagnetic wave, the principle of heating is through the electromagnetic wave in the furnace cavity back and forth refraction and vibration to make the water molecules in the food friction with each other, resulting in heat. The basic principle is friction heat, so the more water containing foods, the faster the heating. Iron can not be used because the iron will reflect the microwave, so as to achieve the effect of heating. Microwave can only penetrate non metal tableware, such as plastic, ceramics, paper boxes, etc.. In addition, if the irregular shape of the iron in the furnace chamber heating will produce electric sparks, often put iron in the microwave oven will damage the magnetron microwave oven - is the heart of the microwave components.
No, if it's a light wave oven
