I have a glass top stove - not my choice; it was here when we bought the house. I also use my cast iron on it, with so far no problems. I am careful with it, and perhaps the surface soesn't look quite as nice as it did, but thats OK with me. I dislike the glass top, but our only other option would be a regular electric stove, and I think I might dislike that more. Getting gas out here would be problematic. But I like my cast iron better than the glass top, so I continue to use my pans.
