How Do You Know If A Mug Is Microwave Safe?
You can know if a mug is microwave safe by looking at the bottom of the mug, which usually has a symbol indicating whether it is microwave safe or not. If there is no symbol, you can also try the “water test” – fill the mug with water and microwave it for one minute. If the mug gets too hot or the water boils, it is not microwave safe. If the water remains lukewarm, the mug is microwave safe.
