Description
Originally described as a thin weathered surface. Natural patinas are usually desirable and are considered an indication of age. They occur on Stone, Wood, Ivory, varnished paintings, and metals due to years of use, handling, cleaning, polishing, oxidation, and/or exposure to the environment. A uniform patina, such as a green copper carbonate layer on Copper or Bronze, can protect the metal from deleterious corrosion. Patinas can also be synthetically induced with chemicals, but this results in a different microchemical structure of the surface layers (see synthetic patina).
