Wow - you are lucky it happened the way it did. Glad you were not moving it when that happened.
Did it go from cold to hot, or perhaps it had a hairline crack in it from being bumped or something. I don't think PBW or Oxy would be the problem if everything else was ok... Seems unlikely to me. Either way - count your lucky stars.
