I will be making a Gent's wide Celtic pattern band in platinum with
18K weave. I need to darken the recesses. I'd rather avoid enamel
fill (I think?). I thought about copper plating the recesses and then
liver of sulphur the copper to blacken.
Does anyone know for certain if the copper will stick well to
platinum? Can I rely on a reasonable service life? The recesses are
not subject to abrasion.
Or any other durable suggestions would be appreciated.
