I have lots of cast iron. All from great grandmother and grandmother via my mother. If you are not cooking corn bread in a square cast iron skillet I would advise you to start looking. I throw kosher salt and wipe iron cleaning. If I need a little water that is fine, I just throw it back into the hot oven to assure no rust. We found an antique store decades ago in South Dakota that seemed to specialize in cast iron, from great to really crap condition. We bought the crap, reconditioned and use it still.
