Anyone know anything about alloying gold, or alloys in general? I'm completely, totally, 100% new to casting so I have some super basic questions...
The alloy I need to make is mostly gold plus some palladium and some silver and zinc - the finished alloy has a melting point near 2000F. The pure palladium has a melting point over 2800F which I probably can't reach. If I bring the gold/silver/zinc up to, say, 2100F will the solid palladium dissolve into the mix and form the alloy? Or do I need to heat past the melting point of the Pd?
Also do I need to stir the alloy to mix the metals or does it kinda mix on its own?
