Well, since I hate to waste, I would try to save it by letting it harden and then griding it up and putting the grindules in with a new soap. LIke embed them in to the next bar, by adding about 1 cup per pound of soap. LIke confetti soap, I dont know if it would work though, I have never tried it. But if that happned to me, that is what I would try. i can't promise anything.
