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.

Is there any radioactive material in microwave ovens?
No, microwave ovens do not contain any radioactive material. They work by generating microwave radiation to heat food, but this radiation is not radioactive and is contained within the oven.
Does a microwave transfer heat by radiation?
Yes, a microwave transfers heat through radiation. Microwave ovens use electromagnetic radiation in the microwave frequency range to heat food by causing water molecules in the food to vibrate and generate heat.
Is a microwave a source of heat energy?
Yes, a microwave is a source of heat energy. It heats food by using microwave radiation to agitate water molecules within the food, causing them to vibrate and generate heat.
Can you heat quiche in microwave oven?
No - you will get food poisoning - do not heat quiche in a microwave oven - use a conventional oven & heat thoroughly
What is the function of a microwave?
to heat up food
Is microwave radiation a form of heat wave?
Microwave radiation is a form of electromagnetic radiation, not a heat wave. When absorbed by materials, like food, it causes those materials to heat up due to the vibrations of molecules within the material rather than through the transmission of heat in the form of a wave.
Which property of food is necessary in microwave ovens?
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.
Does a microwave use heat energy?
No, a microwave uses electromagnetic radiation to heat up the water molecules in food, causing friction that heats up the food. It does not use heat energy directly.
How does cooking happen in a microwave?
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.
Is it important to have a magnetron in a microwave?
The microwave cannot cook food without the magnetron that causes the food to heat up!
Is a microwave a heat pump?
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.
Is there UV in microwave ovens?
No, microwave ovens do not emit ultraviolet (UV) radiation. They use microwave radiation to heat and cook food by causing water molecules in the food to vibrate, generating heat. UV radiation is not involved in the operation of microwave ovens.
