Preventing 925 from tarnishing

#1

Hi everyone,

I have source material here which gives a number of ways
to prevent 925 from tarnishing including;

1.Suitable wrapping paper
2.Special protective paper for silver
3.Storage in transparent bags
4.Invisible surface films according to the Thomas Price process or
the dipping process devised by Dr. Finkh.
etc.
Can anyone help with more about number 4?

Unfortunately the source is photocopy with no reference so I can’t
find notes or anything else about this.

Any help would be much appreciated,

TIA

Tom

Tom, one cannot prevent tarnish on sterling- just slow it down. type
in anti-tarnish or cleaning sterling and you may find what you seek.
Don’t use wrapping paper it won’t work- there is special anti-tarnish
paper made by 3M that helps neutralise sulphur containing compounds
that works well for storage.Transparent bags won’t prevent tarnish-
there are specailly manufactured bags for silver that are available
from many vendors that slow tarnishing down. Some people coat their
silver with marine varnish ( not shellac) - I personally don’t
recommend this particularly on valuable pieces as it will eventually
have to be removed and if air bubbles are in the coating tarnish will
get under the sealant rapidly.I think the Finkh process and
Thos.price’s processes are archaic and related to silver printing (as
in photography) - you may try old photography printing references for
retreiving your lost info…rer
