Oxidation Painting (Adapted for home use)

In the late 1970s Andy Warhol began a series of abstract paintings called "Oxidations", iridescent canvases made up of coppery yellows, oranges, and green. Warhol covered canvases with metallic paint and then invited friends and acquaintances to urinate onto the canvas, causing the surface to oxidize. The uric acid reacted with the metallic ground, removing components of the pure metal to form mineral salts. Some colors developed immediately like red or brown while others like blue and green would form later. In this Making It video we explore how you can recreate this process at home (without uric acid). Have fun testing different liquids with PH strips and then hypothesize which fluids will cause the most colorful reactions. To learn more about PH and the chemistry behind the oxidation process, access our free STEAM lesson plan: www.warhol.org/lessons/oxidat...
