Most plastics are not heated by microwaves and will not be damaged. They also allow microwaves to enter the food from all directions, metal bowls would block microwaves except from the top causing uneven cooking.

A microwave heats the food not the container. The container gets hot from the food. A regular oven heats the container which would melt it.

Can you put microwave dishes in oven?

A conventional oven projects heat onto an object, warming it by passing the heat into the object from the heating elements. If the oven is turned off, the heat remains built up in the oven and the object will continue to cook until the heat has been dissipated. A microwave oven vibrates molecules to create heat from inside the object. Once the microwave stops, the molecules stop vibrating and the heat stops. The only heat remaining is eminating from the object as it cools. A microwave dish is sometimes made of plastic, Melamine or glass. None of these are safe to use in a conventional oven. Some glass containers such as Pyrex Glass are made for a conventioanl oven. Other glass containers may break. Glass will not melt with the heat an oven can produce, but the uneven cooling of the outside may differ from the inside and it could break. http://hypertextbook.com/facts/2002/SaiLee.shtml Glass not made for microwaves may break in the microwave. Bubbles in the glass may expand and crack the glass.


Is microwave baking any good?

Microwave baking can be very successful, but recipes and baking dishes need to be appropriate for microwave use. Recipes that depend on a crisp crust created by a dry hot baking in a conventional oven are not appropriate. I think so !

What is the equivalent of 5 minutes on high in microwave to baking in conventional oven?

From a resource which said that a microwave set on high is equivalent to a 375 degree conventional oven setting, and the microwave cooking time is 1/4 of that for a conventional oven; a microwave set on high for 5 minutes would be the same as a conventional oven set at 375 degrees with a cook time of 20 minutes. You might have to adjust a bit from that with trial, but it should give you a starting point to work from.
