Oxidation Painting

Andy Warhol's "Oxidation Painting" (1978) is a striking example of his late Abstract expressionism and Abstract works. Created using a Canvas as the base, Warhol applied urine to specially prepared metallic surfaces, initiating a Mixed technique that produced unpredictable oxidized stains and iridescent textures. This radical process emphasizes the chemical reactions and spontaneity characteristic of Abstract expressionism, transforming the canvas into a highly visceral and conceptual piece. The painting exemplifies Warhol's experimentation with unconventional materials and his interest in biological and chemical processes.
