Dirty Penny™

Zahner 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 an slick surface.

The Dirty Penny Patina has been used on a range of projects, most notably, the Hoag Rawlings Building, pictured below.  

Like any patina we offer on copper, the Dirty Penny™ Surface 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, it's protective qualities growing stronger as it does.
