Thus far I’ve only worked with sterling silver, but I’ve designed and carved wedding bands in wax for myself and my fiancee to be cast in 18K yellow gold. These will just be simple bands with no soldering, stone setting, engraving etc.
Once I get the bands back from my caster (who cuts off all sprues and give the pieces an initial clean and tumble) I’m wondering what is different about working with gold (besides the price tag of the material!). For instance can I use the same files as I use with my silver if I make sure they’re cleaned well first? Are there certain flex shaft polishing attachments that work well with yellow gold or conversely should not be used with gold?
I’m anticipating I’ll need to grind a little where the sprues were attached and then polish the bands, and I’d love to know about any gold tricks or hangups to be aware of before I make a costly mistake! Also any basic resources for working with gold you’d suggest?
Thanks in advance!
