Tarnish is a chemical reaction on the surface of metal (copper, brass, silver, etc.) and causes a layer of corrosion. In the case of silver tarnish, the silver combines with sulfur and forms silver sulfide (Ag 2 S), which is black. The original silver surface can be restored if the layer of silver sulfide is removed. [4]
Hastening the decline of the corroded iron, the buildup of corrosive discharge exerted pressure on the riveted copper saddles that had held the iron bars in place. This created buckling and warping, and further caused the rivets to become disjointed. Rainwater would seep into the holes in the copper sheathing which once held the disjointed rivets.
Black oxide for copper, sometimes known by the trade name Ebonol C, converts the copper surface to cupric oxide. For the process to work the surface has to have at least 65% copper; for copper surfaces that have less than 90% copper it must first be pretreated with an activating treatment. The finished coating is chemically stable and very ...
This process is usually done on museum works; we recommend a conservation or restoration process for home use of antiques.
