How to separate a bowl from a saucepan, which got melted and welded inside the saucepan while cooking?

After cooking something in a bowl over a saucepan of water, the stainless steel bowl has become welded to the stainless steel saucepan. I can understand that both must have become expanded with the heat and stuck. Now it has cooled down, the pots still have not separated! Can anybody suggest something?

Try greasing the joint with some cooking oil
If there is still water in the saucepan put it back on the heat and bring back to boiling. The saucepan should expand and you can remove the bowl wearing an oven glove.
The pot probably heated before the bowl inside of it thus expanding first and allowing the bowl to slide down the tapered edge of the sauce pan. After cooling it made a very tight grip. The other possibility is that the steam escaping from the sauce pan created a vacuum when it cooled. My guess is it is not wielded. that would require some Intense heat and melting. If you have some wood that you don't care if it gets scared turn the sauce pan upside down and start banging it on the wood this might loosen it. Of course you don't want to bang so hard that you break the handle. This may take considerable time an patience or might work of the bat. If that doesn't work heat the sauce pan and repeat same banging technique. Keep in mind that what ever is in that sauce pan is coming at you, so take precautions not to burn yourself. While banging if you could go to alternate sides, as well as front and back repeatedly this may also help. if you can't do the back side by the handle just concentrate on all the other sides. A little oil as suggested by a former person added to this technique might help just make sure it is applied before heating. Cold oil may defeat what you are trying to accomplish.
Set the sauce pan in a sink full of ice water, this should cause it to expand and will allow you to remove the bowl.
Try setting the saucepan in warm water and at the same time put ice in the bowl. The pan should expand and the bowl shrink, breaking the vacuum seal between them.
put both in the oven and heat it up. the expansion rate is different and it will allow the removal of the bowl.
