Oxidation Paintings are made with urine applied to a copper ground. I first got the idea to make oxidation paintings when I was asked by Eric Shiner to be in an all female group show at The Andy Warhol Museum. Rather than urinate directly onto the paintings I collect the urine and apply it in different ways including pouring, brushing and spraying. The Oxidation Paintings do not stop oxidizing when they dry. With changes in heat and humidity, the process will continue, creating more green patina, until it reaches a stabilization point with its surroundings. The Oxidation Paintings are like us, engaged in a living process of becoming and change.
