(All our brass photos were taken in bright sunlight, and closeup...which makes the colors look more intense than they do at a distance and in dimmer light. From a few feet away, out of sunlight expect a more subtle looking patina...closeup and in bright light they look like this)
Brass money clip with a patina. After the patina, we apply a clear lacquer coating.
The nice thing about brass is that its a "living" surface, meaning it changes with time. High wear areas will polish up to shiny brass, low wear areas will keep the patina, bare areas will be affected by its environment...what colors form depends on your body chemistry and exposure....browns, blacks, green, blues, etc are all possible.
