the color or incrustation which age gives to works of art; especially, the green rust which covers ancient bronzes, coins, and medals
Origin: [It., fr. L. patina a dish, a pan, a kind of cake. Cf. Paten.]
Patina is a tarnish that forms on the surface of copper, bronze and similar metals; stone; a sheen on wooden furniture produced by age, wear, and polishing; or any such acquired change of a surface through age and exposure. Patinas can provide a protective layer to materials that would otherwise be damaged by corrosion or weathering. They may also be aesthetically appealing. On metal, patina is a coating of various chemical compounds such as oxides, carbonates, sulfides, or sulfates formed on the surface during exposure to atmospheric elements. Patina also refers to accumulated changes in surface texture and colour that result from normal use of an object such as a coin or a piece of furniture over time. Archaeologists study the patinas found on flint tools and ancient stone monuments. Stone develops a corticated layer over time that is due to a range of complex factors. This has led stone tool analysts in recent times to generally prefer the term "cortification" as a better term to describe the process than "patination".
