    I wouldn't recommend this ..... Red golds , esp. 18k gold/copper
    binary alloys need to be quenched while still very hot , they should
    be quenched from Red Heat. They can harden so much , if cooled too
    slowly that you can have castings break ! 

    Keeping red golds red is something of a challenge . Fire coat  *very
    well* [ try using dry boric acid , repeatably heating and dunking
    into the powder to build up a good coating ] don't pickle remove
    firecoating with hot water and your ultrasonic. 

    Could you "reverse"plate  [or strip] in gold/plating solution?  Use
    the piece as the anode and plate the gold onto some scrap?  I
    haven't tried  this as I've always been able to sand/buff the rose
    gold to a satisfactory finish.
