I have cast iron but I can't use it because I have a glass top stove.
Don't let that stop you because you can use your cast iron on a glass top stove. I've had many people tell me the cast iron will get too hot and shatter the glass top stove. Actually, that's not true either. Lodge cast iron uses a glass stovetop on their cooking demonstration video. Here are some helpful tips in using your cast iron on your glass top stove.
3. After you've finished cooking and your pan is cool enough to handle, clean your cast iron away from your glass stovetop to prevent the cast iron from being dropped on the surface of the stove. This keeps any accidental mistakes from being painful and expensive mistakes.
Just like any other stove, we have to maintain the stove and keep it clean. Singed food can stain the glass stove. Maintaining and preventing accidents is the key to having a long-lasting glass top stove.
