Beware of “Microwave Safe” labels
The only thing a “microwave safe” label tells you is that you can microwave the container without damaging it or damaging the microwave. In fact, manufacturers aren’t even required to test their ceramics to ensure safety after heating, according to the FDA (that’s probably why you’ve burned yourself on too-hot ceramic mugs). Even though something may say it’s safe to nuke, if you’ve never used it before, the healthier choice may be heating your liquid or food on the stove and then transfer it to a bowl, plate, or mug.
