It crackles and pops. You would probably have to get a new microwave if you attempted this at home.

Can you heat aluminum foil in a microwave?

No. The metal will reflect the microwave energy. The problem with metal of any sort (whether aluminum foil or silverware) is that it can produce an arc inside the cavity of the oven. This can start a fire, and it presents an enormous hazard. Can you use aluminum foil in a microwave oven? Read on. Though it is possibe to use aluminum foil inside a microwave oven, it should only be used if the manufacturer's instructions tell the user how to do it (and the user follows the directions). The microwave oven isn't a good choice to heat the foil itself. Aluminum foil (or any metal foil) will reflect the microwaves and not get hot. If the foil is crumpled or if the foil is near the metal wall of the cavity, that foil can act as an antenna, and the voltages can be extremely high causing arcing. That's bad. It could start a fire. Using a microwave just to heat foil is a poor choice.

Why does the aluminum foil not go in microwave?

A microwave functions by using high frequency waves. Metallic objects such as aluminum foil reflect and react to these waves because of the high content of free flowing electrons. The reflection of the waves can destroy the microwave, and as electrons are released by the high frequency wave they can cause the familiar spark and popping sound.


Can you put aluminum foil in a microwave that has a metal rack?
