Pacific Silvercloth customized pouches

Pacific Silvercloth

• Tarnish protection for silver, copper and other metals
• Proven in the silverware trade and museums for years
• Protects against harmful gases: hydrogen sulphide, sulfur oxides, nitrogen oxides and chlorides
• Cotton with silver particles

Small pouches

The tailor-made bags are provided with a double cotton cord. They are available in two different versions:

• Flat bag, net surcharge 15,- € (excl. price for cloth)
  
• Bag with round bottom, net surcharge 18,- € (excl. price for cloth)
  
• Other sizes or larger quantities please ask our quote.

Principle

Pacific Silvercloth is made of cotton, in which thousands of silver particles are incorporated. During production, a cotton cloth is impregnated with silver nitrate and then the silver is precipitated on the cotton cloth. The surface of the fibers is thus covered by pure, colloidal silver, which offers the pollutant gases a very large surface of reaction. A silver object surrounded by this cloth will be perfectly protected as all gases harmful to silver already will react with the silver of the cloth before they reach the actual silver object. Pacific Silvercloth does not release any chemicals and thus has no harmful effect on other art objects. The brown color is due to the colloidal silver.

is a 100% cotton fabric embedded with thousands of fine silver particles. It is produced by precipitation of pure, colloidal silver on a cotton fabric. The fabric absorbs tarnish producing gases before they reach the silver items. It is 96,5 cm wide, napped and comes in only one colour which is brown (colour of the colloidal silver on the fibres). Pacific Silvercloth is twice as effective as fabrics embedded with zinc or other metals. It can be effective for several decades depending on the environment. It can be used for silver on display and in storage cabinets.

Application

For silverware in frequent use (like in churches) protective bags can be custom made using Pacific Silvercloth. Absorption of pollutants changes the colour of the fabric from brown to black, so the colour gives an indication whether the fabric is still effective. 

Wear a dust mask when working with the cloth.

General information on tarnish protection for silver and copper

In addition to hydrogen sulfide, some harmful gases such as sulfur oxides, nitrogen oxides and chlorine are responsible for the tarnishing of silver, whereby relative humidity is also an important factor. The previously practiced methods to protect silver - such as paints, coatings or volatile chemical substances (VCI) - have all shown adverse effects. The use of pollutant absorbers, however, prevents tarnishing of the silver without affecting the silver surface.

General pollutant absorbers such as Purafil or activated carbon are able to significantly delay the tarnishing of silver. Comparative tests have shown, however, that special absorbers based on modified zinc oxide or cloths with silver particles perform even better.
