How do I un-warp my old faithful Revere Ware so it doesn't rattle on my glass cooktop?
Suggested Project Book
You can't.
It is not possible to un-warp pots and pans, so sorry, might do better with a regular gas or maybe electric range.
I did this on two frying pans where the bottoms were warped and didn't sit level on my stove. Turn them over on a hard surface. Use a hammer and very gently tap the bottom from the center out in a circle until it lays flat. Check every few taps how it sits on the stove.
Try with a rubber mallet but may not be enough.
