Comment on My ravioli bowl won't unstick. Took about an hour of prying, and still I couldn't unstick the plate.

  Would you want the opposite?

  I thought heading the bowl will expand it slightly and increase the suction, cooling it will shrink it and reduce it.

    Hot air expands and cold air contracts. You want the air in the bowl to be hot so it’s not creating negative pressure.

      I did not think of that, thanks!

        Its the same thing that happens with fridges and freezers. But they have become netter at equaling the pressue.

        Change in temperature (T) means a change in volume and/or pressure

    The air inside is what is causing the vacuum heat the air, expansion, less vacuum. Cool the air, shrinks, more suction.

    Heating both likely the smoothest solution.

      Thanks! I had not factored that in

    I could be wrong, but I really believe heating the bowl is the correct answer.

  Why would you want to cool the plate?

    You want to create expansion in one and shrinkage in the other so that you have movement that helps break the seal. Technically you could do one or the other, but it’ll create more net change if you do both.
