Yesterday I lifted a pan off my stove...just that...lifted the pan to remove the already cooked food, and I heard a loud bang! The glass on the stove top cracked! Now what? will it have to be replaced? Has any of you heard of this happening? If I had slammed the pan down onto the stove, I would understand..but this? sheesh. The only thing I can think of was cool/cold air coming in through the kitchen window hit the hot burner circle What if liquid gets down the crack now?
