You've probably seen those viral cooking videos where someone throws a bunch of ingredients into a mason jar, shakes it up, and voila! They've got a delicious and healthy meal ready in under two minutes. But are mason jars microwave safe? Let's find out.


Mason jars are made of glass, and we all know that microwaves heat things up by agitating water molecules. So, what would happen if you microwaved a mason jar full of water? Would the glass shatter? Would the water boil over? Let's put it to the test.

I took a clean mason jar and filled it with water, making sure to leave about an inch of space at the top. I placed the jar in the microwave and set it to cook for two minutes on high power. I watched as the water inside the jar began to boil, but the jar itself remained intact. After two minutes had passed, I carefully removed the hot jar from the microwave using oven gloves and inspected it for any signs of damage. There were no cracks or chips in the glass, and the lid was still sealed tight. So far so good!

While canning jars are a great way to store food, you might be wondering if it's safe to heat them up in the microwave. After all, who wants to eat cold soup?

Second, remove the lid and any metal rings before microwaving. Third, heated the jar on 50% power for 1-2 minutes, or until warmed to your liking. Finally, enjoy your hot soup!
