    you may want to try tigold alloy from Hoover and Strong..but order
    it pre- december 14th as they go on holiday after that date. It looks
    like 14kt, acts like 14kt and costs less than silver and isn't as
    dangerous ( fumes) as zinc, in direct casting, and preforms
    outstandingly well in vacum casting, or centrifugal casting ( as it
    dosn't tend towards porosity) An additional feature is that it does
    not tarnish when kept in a sample case or stored away from sulfur
    vapors, for over six months- the addition of a 3M anti-tarnish strip
    will help keep it high polished, if that's what you are going for in
    a finish..
