    You're welcome, Allan. But it should be noted, and John kindly did
    so, that I did make one technical mistake. In truth, the formation
    of sulphides on silver is still properly called an oxidation
    reaction, as in oxidation/reduction mechanisms. My point was to
    explain that what forms, when we "oxidize" or "antique" silver, are
    sulphides, not oxides. But to the chemist, this is still considered
    an oxidation type of reaction, even though it forms sulphides, not
    actual oxides.
