Stacked Pyrex stuck

I have two 2-cup/1pt Pyrex measuring cups that were stacked on top of each other and now are stuck together. I've tried canola oil and soaking in soapy water but it's been a week now. Any suggestions before I toss them?

  1. I wonder if you heated them, or ran the bottom one under hot water, would they come apart.

    1. This dilemma was just addressed in the latest issue of Cooks Illustrated. According to the reader 'tips' section, fill the inner bowl with ice water and it should come out. Good luck!

        Thanks, I'll try the ice. I've been telling my husband we should try putting them in the freezer to see if that helps but we were afraid they would explode.

        And yet another reason why I NEED a subscription to Cooks Illustrated.

          Putting them both in the freezer wouldn't help. Heat causes matter to expand, cold causes it to contract. By raising the temperature of the cup on the bottom, or lowering the temperature of the one on the top (or both simultaneously), they should come apart.

      2. I would stick the bottom in hot water and put ice/icewater in the top on. The bottom will expand and the top one contract...

          That is exactly what I did. It worked like magic, in under 2 minutes!

          Thanks for the suggestions.

          1. Just to add another way, if the ice/heat thing does not work . . . I tried it multiple times to get the two measuring cups apart but it did not do anything. Pyrex is supposed to be temperature non-reactive, so I wondered how this would work and I was not brave enough to stick them in boiling water. I then tried water and soap in the bottom one, which did not work, but showed me the spot where they were jammed together because when I poured the water out, there was an "eddy" around the stuck spot. So I put a thick towel on the counter and put on a oven glove (because I am chicken) and banged the top cup edge above that stuck spot on the towel-padded counter. Clunk, clunk and they came apart.

            1. Tried the hot water cold water method with no luck. Then tried pouring vegetable oil along the seam where they were stuck and it worked! So perhaps the hot water / cold water then with the oil for the final step.
