I work intuitively and through controlled experimentation. Movement and the constantly evolving process is an evident theme in all of my work. I create acid paintings on metal by controlling the oxidation process on brass and copper. Drawing inspiration from the world around us, my pieces are both dynamic and fluid, incorporating color, movement, and texture. Similar to a scientist, I am continuously experimenting with techniques to create different surfaces, colors, and layers within my work. The reactions created on the metals are organic by nature, often appearing as earth-like abstractions.  As the artist, the unpredictability and potential sense of discovery through this process is incredibly exciting. The process is methodical and time consuming and draws together both a scientific and artistic approach.    Each painting combines all of these aspects to create a cohesive, intricate visual flow that challenges the way we view and interpret two-dimensional art. 

Jenny Martos, a Pittsburgh-based artist, specializes in patina metal jewelry and large-scale patina metal artwork. You can check out her artwork at  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. 


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.
