Hi orchidians.

    I will have to melt a part of my stock, but some pieces have very
    hard to reach precious stones, which I would like to keep unharmed. 

    Do any one of you know of a system I can put up to dissolve my 10,
    14 and 18kt gold into colloidal gold? 

    I do not want to use the Acid method.  I have hear of an electric
    method that dissolves the precious metals into a certain "salt"
    solution, that is safe to handle and produces no toxic fumes. 

    Thank you for the info!! 

Best regards,
