Glass, some ceramics and some silicone items work well. Many materials are labeled if they can be used in a microwave. See Related Links for more information.
There are no radioactive materials in microwave ovens: they use microwaves to cook food and heat liquids.
No - you will get food poisoning - do not heat quiche in a microwave oven - use a conventional oven & heat thoroughly
to heat up food
Microwave ovens primarily heat water (they can heat metal as well, although that is not their purpose), therefore food must contain some moisture in order to be heated in a microwave oven. Dried food will not heat well.

The microwave cannot cook food without the magnetron that causes the food to heat up!
When food is placed inside the microwave oven, the microwave released will 'agitate' the water molecules in the food, which causes heat to be produced, which then cooks the food.
No, a microwave is not a heat pump. It generates heat by making microwaves which cook our food by vibrating the particles and making them heat by rubbing together.
It means open up the can, put the food or whatever inside into a saucepan then light the cooker and heat it. You can heat it up in microwave oven but in my opinion, food is not so good when heated in oven.
A microwave uses radiation to cause friction in food, causing it to heat up or cook in a microwave. Infared cooking inserts heat at the core of a food and cooks it inside out.
to heat food
Most people use the microwave to heat coffee or make popcorn. But it can do so much more. For example, it is use for any recipe that calls for braising, poaching, or steaming. Remember to take the food out a minute or two before it's completely done. As soon as the microwave energy is absorbed by the food, it is converted to heat so the microwave energy can not contaminate the food.
