Can a Microwave Oven be used to boil water?
Health Canada suggests that microwave ovens can be used to boil water using microwave-safe containers but cautions against forming superheated water. Superheated water is heated above the boiling point without the formation of steam and can result in burns to the hands and face. When using microwaves, Health Canada suggests inserting a glass rod, wooden or plastic spoon in the container to prevent forming superheated water.
