We used to get a couple of silicone rubber RTV mold making compounds from
General Electric Silicones, These were bought through local Boston
industrial suppliers. There is probably one near you.
http://www.geplastics.com/ has an overview but no detail. You have to
contact them to get details.
They are 2 part compounds that when mixed make a tough silicone rubber that
does not stick to the model. They resist melted lead and can be used with
epoxy molding compounds for a certain length of time before they detiorate.
Cost was about $50 for a pint. The mix must be vacuumed to get air bubbles
out. I had a vacuum chamber and pump for this purpose..
Also silicone molding supplies are for sale by Rio Grande, the jewelery
supply company $26 per pound.1-800-545-6566. Their compound is a putty
whereas the GE is a viscous liquid.
