    Lyn, I have always used a solution that is commericially available
    from most any of the jewelry supply houses. Some places call it
    Silver-Black, and others call it Win-Ox or something like that.
    Indian Jewelry Supply (Gallup, New Mexico) has a good selection of
    oxidizing agents in their catalog. BTW, I have no affiliation with
    them; I just happen to have their catalog sitting in front of me. The
    solution is a mixture of "stuff", but the primary agent in it is
    hydro-chloric acid so use it in a well ventilated area. When
    oxidizing gold, I have usually applied the solution, and then heated
    the piece a little to get the best results. Good luck
