I'm moving somewhere with a ceramic-glass stovetop. I don't want to stop using cast iron but I heard that they scratch the surface. There's a similar post but it's about enameled cast iron, but mine is bare.
Has anyone used bare cast iron on this surface, successful or not?
If not, I'm considering:
1) grinding the bottom of the pan until it's smooth
2) getting some type of heat diffuser (I'll take recommendations)
3) accidentally dropping the pan until I need to buy a new one
