How to test if a dish is microwave safe
Fill a cup with water.
To test if a dish is microwave safe, you can put it in the microwave with a cup of water. Find a glass or cup that is microwave safe, and fill it three-quarters of the way with water.
It's important to use a cup that you know to be safe for the microwave, otherwise the test may not work. To be certain, find a cup that has the microwave safe stamp on the bottom.
