    I have been wondering how Cobb could possibly have a metal that
    lives up to the marketing spin. Well, I am not totally objective, I'm
    in that business, but my research into white gold issues is years
    long and many castings/bars deep. High nickel gives good color.
    Acceptable malleability will come from an exact temperature and
    timing sequence that keeps the grain structure small.  Hey folks we
    all understand white is here to stay. The basic compromises will stay
    as well.  I will be watching to see if the applied for patent stands
    up to prior work challenges. 

    I'm gonna go out on a limb here.... There is far more advancement to
    be made with technique that with formulas in white gold. Copper and
    nickel do no get along well, fire cracking is a problem. That's
    cracking when you heat the gold. Very frustrating-Heat to anneal and
    it breaks. Palladium is too expensive for many. AAAGH! The usual
    white gold trade offs will always be there. 

    I had already decided that the next video I do for Ganoksin will be
    the Definitive Guide to White gold. Long on metallurgy and method and
    nearly bereft of sales pitch, I'll run down all the things you need
    to know to use the right white gold. Shooting began last month. I
    hope to finish by before the holiday break. Thanks to Hanuman for
    providing the server!
