How to remove small ceramic bowl from inside ceramic cup? - small ceramic bowls

I already have many methods to remove glass and other glass, but it seems to work: (
The ceramic bowl made in small, does not seem too narrow.
I have tried to cut water and boiling water into the bowl of ice cream inside.
I tried to throw boiling water on the bottom of the inverted cup.
I have tried to freeze the freezer, then soak in hot water.
I have tried to use cooking spray to get between the cup and saucer.
no luck so far.

I do not care if it destroys the inner lining. I really want to save to the outer shell.

Thanks for the suggestions!
