Mary,

    I looked at your picture. If you have been doing this type of work
    before, and you are experienced, it seems to me that there might be
    something wrong with your castings. I cast and fabricate, and when I
    solder, just using paste flux, My silver never looks like your
    picture. Flux, solder, pickle, even repeated soldering should not do
    what your pictures shows. If that is not what it is, seems like it
    is some contaminated or poorly cast pieces. The random pattern is
    not what fire stain looks like. I used to do production casting, and
    I once had contaminated metal. The pieces were brittle, like like dry
    pasta. You could just snap the pieces in two. I believe it was lead
    contamination. You might have to scrap those castings, start with
    better pieces.

Richard Hart
