Is it ok to put my pottery coffee mug into a microwave?
I’ve noticed that the handle heats up so much that I can’t hold it right away.
Yes, you can usually microwave pottery coffee mugs, but you should check for any special instructions and be careful about the mug’s decorations.
Safety considerations
Glaze: The glaze should be non-toxic, dishwasher safe, and create a barrier that prevents moisture absorption
Metallic decorations: Avoid microwaving pottery with metallic decorations like gold or silver trim, as these can spark
Cracks: Avoid microwaving pottery with cracks, as they can worsen with heat
Temperature: When heating liquids, start with short intervals and gradually increase the time to avoid cracking
Handle: The mug and handle can get very hot, so use oven mitts or a towel
Testing
You can test if a mug is microwave safe by filling it with water, microwaving for 30 seconds, and checking if it gets hot.
Other considerations
Some handmade pottery may not be microwave safe, especially bisque fired work
Always check for any specific care instructions provided by the manufacturer
