It was in some dense tomato soup and didn’t spark at first so I just walked out and left it on for 15 minutes. Soup tasted a bit funny but that could just be my cooking.

If it successfully heats the water then all is well. August 3, 2015 at 8:22 pm #429352 yorkie86Participant Re: Accidentally left a teaspoon in the microwave. Thanks. Seems to work OK, and this suggests it shouldn’t be a problem. https://www.physicsforums.com/threads/metal-in-microwave-why-not.95607/ Author Posts Viewing 3 posts - 1 through 3 (of 3 total) You must be logged in to reply to this topic.
