Warhol did a series of paintings known as the "oxidation series." Basically, (this is quite disgusting) he painted a canvas using a flat color, and then had one of his assistants pee on the canvas. The urine changed the color of the original canvas to some really pretty tones (but it's still disgusting). I tried doing a spin off of this same technique. I created oxidation in the form of rust (which is the final picture I submitted). I took rustable metal objects, and used them to transfer rust from the object to the paper. The process is quite simple. I will list below:
1. Soak 2 pieces of heavy watercolor paper in water for 30 minutes.
2. On a formica desktop, pour water onto the surface.
3. Layer one piece of watercolor paper, and rustable metal objects on top.
4. Pour water over objects.
5. Put second piece of paper over the objects (like a sandwich).
6. Cover with plastic sheeting, then a blanket over plastic, and then heavy items such as books over the blanket.
7. Let sit for 1 week.
When the layers are peeled back, you have 2 pieces of watercolor paper with rust prints. I just finished my first today. Take a look.
