Pacific Silver Cloth

One more note about "Silver Cloth".  I would be very interested in
hearing from anyone who has used Engineered Materials "Corrosion
Intercept", which is a polyethylene film that has been "doped" with
molecular copper.  It has been designed to perform the same
protective function as the silver cloth, but can also be formed into
sealable envelopes.

Ready made bags of Corrosion Intercept are available with "zip-lock"
seals, transparent windows,  etc.  One advantage of this material is
that it turns from copper colour to black when its holding capacity
is exhausted.
