Embossing is the art of
pressing a pattern into metal and has been performed since ancient times.
Patina refers to a colored coating that develops on the surface of a metal
exposed to corrosion. Copper has a tendency to form a green patina due to
exposure to the elements. This has been occurring for many generations. The
earliest references to purposeful patination of metal goes back to Medieval
times. Today patination of copper jewelry is done by oxidation with chemicals
and/or fire. The copper pendant pictured
above has been embossed with the sixxix machine and given a beautiful green
patina.
