At some point it will be time to upgrade from silver to white gold, however I would like to know what to expect in regards to this upgrade sooner than necessary. I plan on alloying the gold myself, with pure palladium, silver and copper with around 16% palladium in the finished alloy to have a nice, warm, steely grey colour and avoid the yellowish-brown of low palladium alloys. I am not averse however to using palladium master alloys, although I would prefer higher palladium content (50+ percent palladium) I am concerned about the melting point, will I need a different ingot mould than cast iron? Will I need a crucible designed for platinum work? Would I season this crucible as per usual (because I am working with gold, not platinum) if I do use a platinum crucible? Are there any other things about palladium white gold I should know before attempting this?
Additionally, would a smith’s little torch be sufficient for the alloying and melting of the finished gold or would I need a different torch. If so which one? Hydrogen is not an option, I use propane and oxygen. Thanks for any input,
