I know it's not strictly DIY, but I'm tasked with getting them apart !

Two bowls on the same diameter and are well wedged together slightly
at an angle. I wonder if they been taken out of the dishwasher hot by
one of the members of the family and have effectively 'shrunk'
together, but they certainly won't come apart.

Any ideas - I've tried hot water and then the deep freeze without
success - maybe significant oven heat ?

I had no success using thermal techniques with a pair of pirex glasses.
Eventually, decided I might as well force it. Put on a pair of leather
gloves to avoid cutting myself, and then pulled them apart. They came
apart, leaving a thin sliver of the rim of the outer one suck to the
outside of the inner one, which had to be flicked off. Chucked away
the one which lost a bit of the rim.
