Hi Noel,

    Yes, the germanium in the alloy combines with oxygen to create
    germanium oxide. The germanium oxide does not let oxygen through,
    thus preventing tarnish and firescale. 

    In terms of your question "what do we need the "standard" alloy
    for?" I think, from what I've seen with the few pieces that I've made
    with it so far, I'll be using AS 970 rather than AS 925 when AS 970
    becomes more readily available. 

    As for other people....heck, I have no idea. Argentium Sterling is
    less expensive than 970 Argentium Silver, since it has less silver.
    So far, that's the only downside I see. It is really very little more
    money, though--on line, 970 AS is only 20 cents more per troy ounce
    than 925 AS.
