Patina is best described as what?

• A. A jewelry term
• B. A surface finish on metal that develops with age
• C. A type of engraving
• D. A type of cloisonné

Answer: (B)

Patina is the thin surface layer that forms on metal as it ages, due to oxidation and exposure to air, moisture, and chemicals. This aging process changes the color and texture of the surface, giving objects an antique or well-used look, and it can even protect the metal beneath. It’s not a term for jewelry, nor is it a type of engraving, and it isn’t a cloisonné technique. Engraving involves carving designs into metal, while cloisonné is an enamel technique separated by wires; patina describes the aged surface condition itself, whether natural or chemically induced to achieve a desired color.
