Their quality would be greatly diminished and any bacteria that was present in the eggs would have grown to bountiful numbers.
The microwave oven is one of the great inventions of the 20th century -- you can find them in millions of homes and offices around the world. At one time or another, we've all been told not to use metal products, especially aluminum foil, when cookingÂ­ with a microwave oven.f these sparks hit something else in the oven, perhaps a piece of wax paper, you'll probably be reaching for the fire extinguisher. While it's highly unlikely that a small piece of foil is going to cause your microwave oven to totally explode, it could cause a fire.
For short-term warmth, you can use foil, but it will not keep the food warm for long. Foil conducts heat, letting it pass through to outside of the food. The foil does not insulate or hold heat in without help. Use a layer of plastic wrap outside the foil or put the foil-covered food into a plastic freezer bag. They are thicker than the general storage variety of plastic bags. The plastic layer will help the foil to hold in the heat longer than a half-hour.
