Once the ring is free you can follow instructions for the method you like for keeping this from happening again. As a suggestion, here is how I would proceed: tape a single layer of a Teflon® non-stick art sheet together so it fits the mandrel in the area where you are making the ring. Slip this ''cone of non-stick work surface'' onto the mandrel then place the ring onto the non-stick work surface. Reform or refine the ring until you are pleased with the shape. Let the ring rest and begin to dry. Once the ring is dry enough to be removed from the mandrel, carefully slide the non-stick work surface off of the mandrel and let the ring dry further. Once you are sure the ring is dry enough to where the shape won't be affected, remove the non-stick work surface from inside the ring so it can dry completely.
