    Over the years of working in a different field, I have noticed that
    silver seems to be especially susceptable to sulfer bearing
    compounds. I once had a customer where the 15% silver brazing would
    get eaten out of the joints. They did casting of special magnets.
    Also the silver, copper, and aluminium get eaten up quickly in the
    coils of little refrigerators where they store salads; most
    especially onions. Many of those coils are expoxy coated for that
    reason. 

    Perhaps one of the chemists will explain this further.
