Just f*ed up our oven... apperently you can't.
microwave
You can heat any food in an over that you would in a microwave, you'll just have to put it in an ovensafe container. For example, you can't put plastic in the oven but it works in a microwave.
plate
salad can not be cooked in the microwave.
No, just because it's microwave safe does not mean it's oven safe. The thermal mechanisms involved in microwave radiation and convective heat are completely different. Many plastics are microwave safe, but you should never put plastic in the oven.
The microwave oven is used to heat or cook foods quickly and efficiently. It is effective at heating anything with a high water content, so reheating drinks is a snap. The oven itself doesn't need to "warm up" to be effective, and many cups, bowls and plates can be put into the oven and used immediately upon removing them. A microwave oven also provides an unmatched level of convenience, and this is probably one of the supreme advantages of having this appliance handy.
It is not usually nesessary to put a cover on food in the microwave oven. Some people cover food to prevent soiling the inside of the oven.
Yes it is ok. Just do not put it in the microwave. It will spark.
Absolutely not! Enamelware is metal. Oven safe, yes. Better not try it in the dishwasher either.
put it in a microwave oven
Yes you can. You cannot though if it's a microwave oven, and you cannot put on the oven itself, only as a lid for a pan etc.
smother it or use a foam fire extinguisher
