patina

See figs. 293, 306, 307, 308, 309, 313, 314, 323, 326, 328, 332, 338, 500.

The term has at least three different meanings: 1) a pleasing surface alteration acquired over time—whether on a or marble sculpture, furniture, or a painting—that may add aesthetic value; 2) the chemical transformation of a metal surface; to a mineral layer (sometimes referred to as chemical patina, see ) that usually has a different color from and reduces the bright metallic reflectance of the polished original surface; or 3) (as opposed to chemically induced patinas) organic such as resin, lacquer, oil, wax, or synthetic resins applied to the surface of metals that can change the color, texture, saturation, and/or reflectance.

Note: Some researchers do not consider applied organic coatings part of the patina layer.
