Silver Conservation (4021 words)
Silver is a very noble metal and is often found in a native state combined with gold, tin, copper, and platinum.
Silver is particularly susceptible to the effects of the sulfide radical.
During electrolysis, the reduced silver corrosion layers regenerated on the surface of the metal in formic acid are left in granular or particulated layers, which are physically weak and tend to separate from the metallic core.
