    Saw a "new" alloy at tucson, a 5% PT / 95% Ag mixture, selling at
    about $20 per ounce over respective spot price. visually, looks
    pretty much like fine silver. 

    starts at about 7200 brinell, heat treats to about 7800, melts at
    normal sterling temps plus about 100 degrees. 

    would anyone use this in place of 14/18 kt white?
