Safe to microwave soup in a pickle jar?

I put left-over soup (miso/tofu/noodle concoction) in a pickle jar to bring it to work.
I was thinking it would be safe to reheat it in the glass jar (lidless obviously) in the microwave. Is this gonna work? Or am I gonna have a microwave full of soup and broken glass?

Thanks in advance!

  1. Not safe, unless your pickle jar's made from tempered glass.

    It's not so much that the microwaving will have any effect on the glass jar, it's the change in temperature from cold to hot -- and then to cold again when you take the jar out of the microwave.

    At home, I'd say put it on a plate and give it a try, removing the jar with a napkin and eating carefully. At work, I just wouldn't risk doing something like this.

      My experience is that sometimes it works, and sometimes it doesn't. It's probably not worth taking the risk at work.

    2. I just heated miso soup in an almond butter jar for 2 minutes and it was fine. I store most leftovers in old glass jars and reheating hasn't been an issue, although I don't use the microwave all that often.

      1. Thanks for your input folks. I was hoping for a tie-breaker. And, erring on the side of caution, I ended up heating my soup in a ceramic flower pot. How embarrassing.

          I have a microwave in my office. I keep a round 2-3 quart (safe for microwave) pyrex baking dish in it. When I reheat stuff, the food goes into a bowl or other container, which then sits in the baking dish. That way, if the bowl/container cracks or leaks, the pyrex dish catches the mess. Keeps the microwave cleaner too (unless the food pops or explodes).

            Didn't the soup run out of the drain hole in the bottom?

          2. I frequently store leftovers in old jars and microwave them. I've never had a problem.

              Karen, where were you an hour ago when I needed a tie-breaker?! ;}

            2. I just tried it out. It's safe but not very effective. The jar got blazing hot yet the contents not so warm... You're better off putting it in a mug or something.
