"I am not sure about throwing cold water into the fire? It would turn to steam and force the fire out, but I would worry that it would crack the tiles. "

Don't do that!

I had a super hot fire once due to adding coal that had the pipes glowing red.
Scared me so I tossed in some snow to cool things down.

BOOM, now that really scared me!--(house was so hot that we could barely breathe).
BTW there was no creosote.
