Do you have a company name that makes molding and casting wax. I would go with the proffesional stuff if I could try out a small amount first. What I've seen is 50 lb blocks. Maybe I could get small amounts on E-bay. I did see 4 oz. blocks of Carnauba.
Tapplastics has some good looking 2 part silicone for molds and some videos on U-tube on how to use it. Have you heard of the "Bombs Away" method to get bubbles out?
