Patina is a chemical process that alters the surface of a metal leaving a colored compound adhered to the metal. Patinas form on metal from exposure to the elements of nature but can also be deliberately controlled.

Colors are formed through a forced oxidation process on the metal (copper or brass) Different combinations of salts and acids are used to create patinas. By controlling the patina process, different textures, colors, and layers are added to a piece. Once a piece is finished, an epoxy resin or lacquer is used to seal in and stop the oxidation process as well as protect the patina.


Jenny Martos, a Richmond-based artist, specializes in patina metal jewelry and large-scale patina metal artwork. You can check out her artwork at www.jennymartos.com.  Through much experimentation and research, she has learned to manipulate oxidation and control the effects of color, patterns, and texture on different metals. Jenny’s work is always evolving due to continuous exploration in oxidation techniques on metals.
