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]
Green death is a solution used to test the resistance of metals and alloys to corrosion. It consists of a mixture of sulfuric acid, hydrochloric acid, iron(III) chloride and copper(II) chloride and its boiling point is at approximately 103 °C. Its typical chemical composition is given in the table hereafter: [1] [2] [3] [4]
The beads, typically 100 μm in diameter, are highly elastic, leave no residue, and produce a metallurgically clean surface without abrasion. Unwanted scale, accretions and corrosion products are shattered and knocked off by the force of the blast, and the metal surface is peened or worked on a microscopic scale.

Green rust (SO 2− 4) synthesized under anaerobic conditions in the absence of dissolved oxygen. Green rust is a generic name for various green crystalline chemical compounds containing iron(II) and iron(III) cations, the hydroxide (OH −) anion, and another anion such as carbonate (CO 2− 3), chloride (Cl −), or sulfate (SO 2−
The Statue of Liberty, showing advanced patination; verdigris is responsible for the statue's iconic green colour.. Verdigris (/ ˈ v ɜːr d ɪ ɡ r iː (s)/) [1] is a common name for any of a variety of somewhat toxic [2] [3] [4] copper salts of acetic acid, which range in colour from green to a bluish-green depending on their chemical composition.
