We used to electro-strip and then reverse-plate using the same
solution. Even though I believe it was cyanide based, it was
definitely a safer method than bombing. Not as bright, but then it’s
purpose was to give a uniform appearance to a ring that had had
multiple heads installed or soldered parts. As I remember, it looked
about 18K -22K - even if the product was 14K.
This only works if the stripping solution has been used a bit
beforehand - to saturate it with gold. I never understood why the
gold reverse plated back out and the copper stayed behind? John
Burgess wanna take a crack at this?
Also, I seem to remember that there was a simple method to
destroy/neutralize the cyanide solutions and drop out the gold at
the same time. It’s in my notes somewhere… John again?
