making molds

[Shiny]

so for a class im supposed to be making some molds to use with glass. What should I make them out of and how deep should the deepest part be. I assume ill just be getting glass really hot and shoving it in. These molded pieces are going to be pendants so thats about the size im lookin to do. Any suggestions?

Any suggestions?

No undercuts!

Coat your mold with graphite dust to ease seperation anxieties.

there is a product called Best Mix. www.bestmixproducts.com
its supposed to work for fusing/slumping so it might work for your application. Its sure easier to shape and work with than graphite if you dont have the tools to shape graphite
