Stop silver tarnish with vacuum storage?


#1

Hello all you brilliant metalsmiths,

Just had a thought-Does it seem reasonable that if you stored silver
in a vacuum it would not tarnish? Seven months ago I put a pair of
earrings in a plastic vacuum food pouch and sealed them. To date
there has been no tarnish. The problem is it is time consuming and
it H doesn’t look professional when I need to show it to a
prospective gallery or shop. I would like to put each piece in an
unclosed plastic bag for scratch resistance and then store about
50-100 pair of earrings, pendants etc. in a rigid plastic container.
Does this sound reasonable? Has this been tried by anyone? If so,
what equipment did you use?

Thanks for your help in advance,
Richard Langbert

Hello Richard,

The less exposure to the atmosphere, the less tarnish. I store my
pieces on their cards in Tupperware-type containers, which have
silvercloth liners. This keeps silver pretty shiny for the show
season.

I also use those anti-tarnish resealable plastic bags which seem to
work well for a while (I think the company says 2 years). Of course,
exposure to air during shows and displays means some dulling of that
lovely silver finish. Using Argentium/no-ox silver alloys does help,
and whenever possible that’s what I use. However, shop wear happens
and those fingerprints customers leave are awful.

Regardless, soon it will be the time of year to clean and recard in
preparation for the 2012 show season. I’m dreading inventory
already!! In the meantime, have wonderful holidays and travel safely.

Judy in Kansas, where the promised show is falling softly. A good
day to drink hot toddies and bake cookies.

Just put them in ziplocks with anti-tarnish strips or use
anti-tarnish cloth.

No oxygen equals no tarnish. The tarnish is caused by an oxidation
reaction. So if you keep the air away from your silver it will not
tarnish.

You could coat them with Brownpolymer. We had the university of
Buffalo test the polymer and found the film that it leaves is a
protean lipid membrane with a constant angle of 24. Which means
organic substance will not adhere to a surface this also means that
water or air will not attack the surface if it’s applied correctly.
Buffing or rubbing on the surface is all that is need to release the
membrane. Many people have been fascinated by the polymer and thanks
to Dr Baier help this is what was found Thanks Randy

Actually it’s an oxidation process that causes tarnish, not oxygen.
The culprit is sulphur in the atmosphere.
