    Hi Chris,  There are many other environmental factors that could be
    contributing to the tarnishing of your silver as well as the leather.
     To determine how much of a factor the leather is, I would modify
    your test.  There are two problems with your test as you describe it.
     Sandwiching the leather and silver between sheets of Plexiglas will
    exclude oxygen from the surface of the silver.  You also have no
    control against which to compare your test results.  I would place a
    few end caps with the leather attached in your oven as you did before
    and see what happens.  Then I would place a few end caps with no
    leather attached in your oven and see what happens with all other
    factors being the same.  These two tests must be conducted
    separately.  This will give you a better indication of how much the
    leather is contributing to the tarnish.  I would also ask what kind
    of environment these items are in for the month after attaching them
    to the leather?  Are there other silver items with no leather
    attached in the same environment that are not tarnishing over this
    same time period?  If the leather is the primary contributing factor,
    then you may want to try an anti-ox silver alloy.  I haven't worked
    with leather so I can't tell you what other leather options you may
    have. 

Best Regards,
Dale
