I can answer this question with a solid no. Once the gypsum is cast and hardened it cannot be turned back into a liquid and re-poured to make a new PYO (if that was the question) a broken PYO might be able to be repaired with apoxie sculpt or some other sculpting medium that is similar in nature to gypsum though.
Got a busted Windstone?
