Can put something in the oven if its already microwave safe?

No, you can put plastic in the microwave which would melt in the oven and metal dishes are oven safe but can't be used in the microwave. Glass works in either.

Yes, silicone is microwave safe. It is also safe to put in the dishwasher, and even in the oven.

Technically you could put them in the oven, but if you are planning to turn the oven on, I wouldn't recommend it. If the dishes are plastic, as most dishes labeled 'dishwasher and microwave safe' are, then they will melt if used in the oven. A microwave is safe as its only a few minutes, and a dishwasher uses hot water.

Yes, porcelain is dishwasher safe, oven safe, but do not put it into the microwave!

Yes, it's great in the oven, on the range, or in the microwave.

Not if this is the plastic Rubbermaid containers that list "microwave safe" on the label. Plastic is not conventional oven safe.

No, regular oven they will burn and microwave the uneven heating will cause them to crack.

Of course! What else is a microwave oven for?

Yes but I would unplug when it is not in use.

No, which is why they usually shut off when you open them.

You can put plastic in a microwave oven; many microwave-safe containers are made of plastic, and most plastic cling-wraps are suitable for microwave use. Some plastic bags are fine for using in the microwave oven. If in doubt about any type of plastic, read the data on the packaging or check with the manufacturer or retailer.
