    David, your Germanium alloy would still be sterling, but why use 7.5
    %?  As the clever metallurgist who devised the patented "Argentium"
    brand of sterling has shown us, all you need is 1.2% by weight
    Germanium to virtually eliminate subsurface firescale.  Oh yeah, did
    I mention that it's patented?  Germanium, being a rare-earth, is
    costly compared to copper, but I wonder how hard it is to process? 
    Could one alloy it in the small shop?  Curious...
