What to do with cereal bowls that are stuck to each other?

[arivecchi]

I bought some Corelle cereal bowls from Amazon and two of them are stuck so I cannot separate them. Anyone have any tricks to deal with this? Otherwise I will just call Amazon for a replacement.

Can you/ have you soaked in a sink of hot, soapy water?

I've used hot water under the bottom bowl or glass and place ice cubes in the top one. That should cause expansion and contraction enough to separate them so long as its not due to something like being placed together while the glaze was wet.

I tried this and they are still stuck. Called Amazon and they are sending replacement bowls.
