This probably deserves a laugh, so feel free

Title says it all. Ran the self cleaning mode, forgot to take the stone out, and it turned from a nice brick/brown color to sort of ash grey/white. I've tapped it with a spoon and it seems solid (it rings nicely anyway), but it's still hot so I don't want to take it out and handle it. Is it still serviceable? Should I be worried?
Thanks! I registered just to post this, but i've been reading here for a while- love the forum
