Detailed explanation-1: -Anything made of or containing steel, iron, copper or other hard metals should never go in your microwave. Metal surfaces reflect microwaves, which increases the heat inside the appliance and could lead to a fire.

Detailed explanation-2: -The metal heats up very rapidly and will eventually catch on fire. By the way, some manufacturers of packaged foods take advantage of this by wrapping their food product in a layer of foil that gets just hot enough in the cooking time to help the food to cook evenly and completely.

Detailed explanation-3: -A large sheet of very thin metal, like a big piece of aluminum foil, can in fact heat up extremely rapidly, becoming so hot that it could start to burn the microwave.

Detailed explanation-4: -No, you cannot put stainless steel in the microwave. Stainless steel is a metal, and metals should never be put in the microwave because they can cause sparks and fires. So, if you’re looking to heat something up in the microwave, be sure to use a container that is made of glass, ceramic, or plastic.
