The mold is made of Smooth On "Stroke" brush on silicone. The mother mold is plastipaste in three parts. I started this piece before the summer and finally got around to finishing the mother mold. It holds together fairly well. I was able to test the mold today using a decent amount of Smooth-On Smooth Cast 300 White Urethane Resin. I made the mistake of trying to add more resin to the piece once the original resin had cured and got a bit of overlap. I went over the overlap with a rotary tool and was able to do some touch ups to get the piece closer to normal again.
I plan to cast a few wax ones Thursday and Friday for a melting piece. I might paint the resin one for fun and mount it as well.

Still a bit dirty from in the mold. Once touch ups are done it will be primed
