I'm building a prop and last night I attempted to make a mold of a button form. I built a clay wall around a bouncy ball that I was molding and poured Smooth-On Mold Star 16 Fast platinum silicone rubber. This morning I went to demold and realized I used a sulphurous clay for the clay wall, so the rubber has not fully set up where it was touching the clay wall. I pulled the mold away from the clay wall and have left the bouncy ball inside the mold for now. My question - now that the mold is removed from the sulfur clay, is there reason to think it will finish setting? Should I give it a day or just make a new mold? The detail around the clay wall has been lost, but I don't really need that - I'm just hoping the detail around the bouncy ball is good.
