I am trying to make a silicone mold of a bell. I use alumilite high strength 3 bc it doesn't require a vacuum. I only have a pressure pot. With that said, the stuff ain't cheap by any means. I'm trying to not waste an entire case of the stuff on my learning curve if the knowledge is already out there. So to the question. How should I mold and demold this bell? I'll be using alumilite resin to make the copy once it's done.
My concerns are mainly about the shape and how I'm going to get it out once I've cast without tearing the mold. So if anyone has any ideas I would really like to hear them.
