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

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

      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.

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