I don’t think the silver will matter - some shakudo recipes have
silver in them resulting from mixing gold with shibuichi, which as
you know is a copper-silver alloy.
The depletion-gilding aspect will be diminished with the silver
content. I mean, if you DO want to deplete the copper out and
produce a gold-rich surface, you’ll actually get a gold-with-silver
surface, unless you use an acid that depletes the sil too.
I think I’d try it if the o’all amount of the silver was small.
Oh, the silver will also upset any patina results.
I like my shakudo (10 - 12% gold in copper) dark blue/black with a
gentle torch and a whole heap of time, and I don’t know if your
alloy will do this as well.
