Verdigris
Verdigris is the common name for a green pigment obtained through the application of acetic acid to copper plates or the natural patina formed when copper, brass or bronze is weathered and exposed to air or seawater over time. It is usually a basic copper carbonate (Cu2CO3(OH)2), but near the sea will be a basic copper chloride (Cu2(OH)3Cl). If acetic acid is present at the time of weathering, it may consist of copper(II) acetate.
