Just want to make sure I am following your method for Keumboo on
Argentium. You would completely construct the piece, get it all
cleaned up, heat it to bring the Argentium back to the surface and
to harden the metal, then abrade the surface you want to apply the
gold to as the last step?
I don't always bother to harden everything, if it does not seem to
need it, so I did not harden the earrings I did. And, I would not
worry about bringing the germanium to the surface----for one thing,
Stern Leach has adjusted the manufacturing process, so that the metal
should be arriving with a nice germanium oxide surface; also, the
heat of the kumboo process would take care of that anyways.
If, however, I wanted to harden the piece, I'm not sure it would
matter whether the hardening was before or after the kumboo. In any
case, though, I have found that a freshly abraded surface worked
Guess we'll have to experiment to see whether hardening affects
