Are Glass Coffee Mugs Microwave Safe?

If you use a glass coffee mug for your morning joe, you may be wondering if it’s safe to put in the microwave. Arc-shaped glass mugs are indeed safe to heat up drinks, as long as you follow some basic precautions.

Things To Consider When Microwaving Glass Coffee Mugs

  • Check For Uneven Thickness – Before you put a glass coffee mug in the microwave, check it for any kind of unevenness. Unequal thickness can lead to breakage or cracking during the heating process, as some parts of the mug will take on more heat than others.
  • Leave Room For Expansion – If you are microwaving a full glass of hot beverage, leave a bit of space at the top of the mug. Hot liquid expands as it is heated, and if it has no room to do so, the mug could break.
  • Pay Attention To Time – Don’t leave a glass coffee mug in the microwave for too long. The best practice is to heat up your beverage for short increments and test the temperature before consuming it.

Are Glass Coffee Mugs Safe?

Overall, glass coffee mugs are safe for use in the microwave, but you need to be aware of the risks and take the proper precautions. To keep your mug in good condition, watch for any sign of unevenness, use caution when heating full cups of liquid, and limit the amount of time your beverage spends in the microwave.
