Use silicon molds and a bit of talc (I think) for release. Make sure your mold is stable enough to hold the weight of the metal. Don't burn yourself. There should be some on-line sources for more details. It's a start at least
BTY - your post count scares me,,,
Depending on the metal and the size of the piece, you have different choices.
As we know, different metals melt at different temperatures. Lead alloys and tin have fairly low temps, and can be cast in silicone molds (such as RTV). Most of your hobbyist metal soldier figures are done this way now. Steel or brass would destroy the RTV mold and cause problems.
As long as the piece isn't too large and the heat will dissipate quickly enough, you should be able to cast nicely detailed tin alloy parts using RTV silicone molds.
His real name is "Glenn Anzalone". BTW, he's 5'4" and is now *48 years old*!!!
Man... I was graduating college when "Mother" was released... I feel olddddd!
(from Danzig's website) be afraid... be VERY afraid...
It is a sinister time in the tired life of one world ending, and it unmistakably a time for the destructive and redemptive powers of the next century's man in black. Heed the warning: Danzig 6:66 Satan's Child is only the scabbard tip of what we can expect from Danzig throughout the birthing of a new rebel century. It is however, Danzig's soul crusher of a calling card, his coal-fired ebony heart made metal, the siren song soundtrack of two ages in collision. Confront it now and feel your lifeblood drain and subsequently replenish truer than ever.
