Preweathered Copper Patina and Oxidation
Dirty Penny™ Oxidation Process was developed by Zahner to offer artists and architects a preweathered copper with dark tones ranging from blues to greens and reds. It has a certain iridescence like water reflected on a slick surface.
The Dirty Penny™ Patina has been used on a range of projects, most notably, the Hoag Rawlings Building, pictured below.
Like all patinas, the surface of the Dirty Penny™ patina will evolve with time. The oxidized layer is like a living protecting barrier which grows stronger as it further oxidizes. Unlike paint, which peels and deteriorates, Dirty Penny™ Patina will age like a vintage wine, its protective qualities growing stronger as it does.
