Hello Bill,

    I assume from your mention of "hardenable silver" that you _don't_
    mean Argentium, correct? 

    I don't have any technical data on Argentium's shrinkage rates but I
    have heard that some "hardenable" silvers contain significant amounts
    of nickel and/or magnesium and have higher than normal shrinkage
    rates. Might something similar have happened to you? If you could
    specify what alloy you were using that would great. 

Cheers,
Trevor F.
