    A related question that just came up for me: does the manufacture of
    sterling silver differ enough to make different batches "take"
    patina better than others? Less copper? I have bottle of true-black
    and it did a few pieces great, then it just fogged it and greyed it,
    then it did black again. Not a clinical test though - could have been
    anything, I guess (my finishing, cleaning, etc). But it was different
    source of silver.
