Loved my tramontina 3 piece induction system from Costco until this happened. Was boiling some eggs as I do every morning and had done for 9 days in a row with this system. This morning I might have had the temperature a little higher but not much more. When the water came to a rolling boil I put 2 eggs in. When it was time to pull them out I shut off the cooktop and went to pull off the lid, but I couldn't because it was stuck. I thought that maybe it needed to cool down so I left it alone now 12 hours. However the lid is still stuck to the pot. I do not wish to force it. I have even held it upside down as pictured.

It seems really unlikely it somehow rusted shut or anything like that while you were boiling, so it seems most likely that there's just a partial vacuum inside. While boiling, it'd have been full of hot air and steam, and now that's all cooled down, and the steam has condensed, so it could shrink down you end up with low pressure inside sucking the lid down. It's a bit surprising that the seal is good enough to hold the pressure for this long, though!

In any case, if that's it, assuming there's still liquid in it, I'd try just heating it again. That would increase the pressure inside, hopefully back up to normal, enough to let you get the lid off. I'd also try twisting and angling it, because if that's it, all you need is a tiny opening to equalize pressure.

If this does turn out to have been the issue, you could probably avoid it in the future by opening the lid immediately when it's done.

    I've had that happen to me, and a vacuum is exactly what happened. I ended up prying it apart carefully, with some clamps and tools, as I had unfortunately, boiled it completely dry. My mother in law also did this as she lit a giant pan on fire, and I threw a lid on before she burned her kitchen down as she starting screaming and moving it around her very flammable kitchen. So yeah, this can totally happen. If there's still liquid in there, then heating it would be my first solution too. – talon8 Oct 16 '17 at 15:57
  • A variant of this is how my mother cracked a ceramic cooktop... – Marti Oct 16 '17 at 17:07

    @talon8 Thanks, that's helpful, I edited to clarify that heating is for if there's water in it. (It looked like probably so, given the droplets and that it was boiling eggs, not just a small amount of water.) If it's dry... yeah, I'm impressed you managed to pry it open like that! The only other thing I thought of was gentle heating and maybe even freezing, in hopes that the two parts would expand/contract differently from the glass lid, possibly to the point of opening enough of a crack for a tiny bit of air flow. – Cascabel Oct 16 '17 at 18:22
  • I don't think that's a glass lid? I did rip the handle off the lid. But the pot still works. I suspect given two metal surfaces... I don't know that you could expand the base sufficiently without also expanding the lid to break the seal. But In my case, my next choice was throwing the whole thing away. – talon8 Oct 17 '17 at 17:08
  • If it's a vacuum it may also work to put the whole thing in another low pressure space (think something like space bag), since if the outside pressure is reduced it should allow it to open as well. – JNK Oct 18 '17 at 17:29

I found an easy way to get the lid off after it happened to me with a pot of brown rice. I had set a timer, so I was pretty sure there wasn't any water left in the pot which made me reluctant to heat it back up. Instead I boiled a different pot of water and set the stuck pot on top of it. Within a couple of minutes the top released without any problems or noise.

Carefully slide a single edge razor blade inbetween the lid and pot and it will release.

  • I would not even recommend this with safety glasses on - the forces are just too great to toy around with breakable razor blades. – user34961 Jan 13 at 21:18
