Patina can refer to any fading, darkening or other signs of age, which are felt to be natural or unavoidable (or both). The chemical process by which a patina forms or is deliberately induced is called patination, and a work of art coated by a patina is said to be patinated.
We use patina finishes on our metal and zinc products as a color
option but what exactly is patina you ask? The best way to explain it is

textures, color and enhances the current metal look. Patina is a tarnish
produced by chemical processes that forms on the surface of many types
of metals. When exposed to the elements, a coating of various chemical
compounds, such as oxides and carbonates form on the surface. Using this
process, it creates a weathered appearance on the metal or zinc which
will continue to change over time.
