I like Jimmy DiResta’s wordless how-to videos. In this one, he casts a skull ring with a silicone mold. I’m not sure what kind of metal he’s using, but it looks like it melts at a low temperature.

    Since it’s jewelry the metal is most likely Field’s alloy. It’s the most common low melting point, non toxic metal alloy.
