ARGENTIUM™ STERLING SILVER ~ PREVENTING DISCOLORATION

• Use a dedicated polishing such as the Goddard’s cloth.
   
• Use a dedicated abrasive wheel.
   
• Rake your wheels when switching from other metals to Argentium.
   
• Plating and cleaning solutions may contain strong chemicals that will remove the protective germanium oxide film from the surface.
   
• Both sulfuric and nitric acid may dissolve germanium.
   
• Recommend using a mild pickling agent.
   
• If strong acids are required, reduce the time of exposure and acid concentration to the lowest level possible.
   
• Deionized water may stain due to the lower pH factor. To prevent these water stains, immediately dry Argentium and/or avoid deionized water altogether.
   
• Heating applied to Argentium in a torch/air atmosphere improves tarnish resistance.
   
• The more heating cycles applied, the better the tarnish resistance.

For Castings

1. After devesting, anneal in air 1050-1150°F (566-621°C) for 30 min. to an hour and water quench after the orange glow dissipates.
    
2. Clean the castings (i.e. using pickle or sandblast)
    
3. Repeat the annealing step #1, the casting should take on a silver-grey luster.

 If you continue to encounter discoloration problems, do not hesitate to contact G&S Metals.
