Is there a way to un warp a pan bottom? I have recently moved into a new home, and for now, I'm stuck with a horrible electric glass top stove.  My old place had a gas stove with a continuous grate across the cooking surface.  All my pans are carbon steel or cast iron.  (I take good care of my pans, so it's not an issue of abuse or putting cold water in a hot pan, or immediately rinsing a hot pan in cold water.  With the exception of my woks, they are bullet proof). 

I am finding that most of my carbon steel pans have a slight warp to the bottom, which was never a problem on the gas range.  But is proving to be rather annoying on the new electric one.  So in theory is there a way to unwarp or to lessen the warping on the bottom of the pan?  In a way this will be academic and I am willing to sacrifice one of my cheaper pans to experiment the unwarping theories.  Thanks.
A technique that works for some car dents is to apply dry ice to the warp and this may cause sufficient contraction from the cold the remove a warp. I think this is a low probability of success...but it might be cheap enough to try.

Second, you might consult a local blacksmith (yep, they're still out there) who has the equipment to heat the metal to where he can 'flatten' it for you. I suspect this would cost more than replacing it.
