    Um, isn't it the other way around? Copper (in sterling) oxidizes,
    fine silver taernishes primarily in response to sulphur. 

    Yes Noel, it is, inasmuch as silver oxide is white! I even think I
    heard that the white residue on f. inst. Sterling after pickling is
    silver oxide. Perhaps our living chemistry encyclopaedia John Burgess
    could clarify?
