So, Can You Microwave Enamel Mugs? (Answered)

So you grabbed a random mug out of the cabinet for your coffee. It happened to be made of enamel.

Now your coffee has gone cold, and you’re wondering whether you can microwave your enamel mug or not.

The answer is NO. You cannot microwave your enamel mug. Don’t even think about it!

Enamel is made up of many different types of metallic materials similar to a thermos. To put it simply, you can think of your enamel mug as a metal mug.

And can you microwave metal? No. So you can’t microwave your enamel mug, either.

When you microwave metal (or enamel), sparks fly — literally! There’s a very good chance that you can start an electrical fire in your home if you try to microwave your enamel mug.

At the very best, you will likely break your microwave and need to buy a new one.

Luckily, enamel mugs are easy to heat up in other ways besides the microwave.

How to Heat Up Enamel Mugs Safely

One of the major selling points of enamel is that when heated up safely, it gets hot quickly, which means the contents inside of the mug get hot quickly, too.

For this reason, enamel is a popular choice amongst hikers, campers, and backpackers. Not much heat is needed for the contents inside of the mug to get warm.

To heat up an enamel mug, place it over a heat source. A flame from a fire or a gas stove works well and is perfectly safe. An electric stove works, too.

Since enamel heats up so quickly, check on your enamel mug every 15 to 20 seconds to ensure your food or liquid isn’t getting too hot.  Want to heat up water quickly for your coffee?  Read our reviews of the best microwave teapots.
