Bronze disease is an irreversible and nearly inexorable corrosion process that occurs when chlorides come into contact with bronze or other copper-bearing alloys. [1] It can occur as both a dark green coating, or as a much lighter whitish fuzzy or furry green coating. [ 1 ]
Protective elements for bronze fountains are particularly important, since water is one of the leading causes for alterations or corrosion in a bronze. [2] Bronze sculptures incorporated in fountains will need more layers of wax, because the spray of water will cause deterioration of the wax at a faster pace than would normally happen ...
Bronze, or bronze-like alloys and mixtures, were used for coins over a longer period.

Gunmetal ingot is a related alloy in which the zinc is replaced by 2% lead; this makes the alloy easier to cast but it has less strength. [2]Modified gunmetal contains lead in addition to the zinc; it is typically composed of 86% copper, 9.5% tin, 2.5% lead, and 2% zinc.
