Can any of the molds here be used for metal?

I am a jeweler and looking for ways to make reusable molds for lost wax casting. Would any of the examples you make in these lessons work for silver, brass or the likes?


Hi AngleAh,

I'm afraid that silver and brass's melting temperatures (1,763°F and 1,652°F respectively) are too hot for the materials I use/discuss in my class. Smooth-On makes a product called Mold Max 60 that will withstand up to 560°F / 294°C which would work for tin and pewter, but not silver or brass.

Sorry I don't have better news for you!

Best,
Paige
