Patina is a change in the surface appearance of a material, often seen as a layer of color or texture that develops over time. It commonly occurs on metals, like bronze or copper, due to exposure to the elements or aging, creating a green or brown coating. Patina can also refer to a similar aging effect on wood, leather, or other materials, giving them a distinctive, often valued, look and feel.
