What's the story on whether cast iron pans work well on a glass cooktop?
That's what we have... we'd like to get one if they cook well on glass.
The only thing I've found online regards the possibility that the bottom of a cast iron pan could scratch the glass:
Scratches can not be removed. To avoid scratching, use pans with smooth bottoms. Rough pan bottoms and foil pans will scratch the glass.
