    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?
