Torso. Somewhat failed experiment in acrylics; the ink and fluid repelled, but not in a way I liked.
Whack. This board was beat off ground in two directions; note beading, especially on shoulder.
Drea. Example of acrylic and graphite used at once.
Per request from my artist's statement, here are the answers to the seemingly random questions:
What happens when you combine ferrous powder with an oxide?
They repel. Or collide. It's an incredibly interesting battle to study as I literally "watch paint dry", as one is mainly magnetic and the other much like (or is) iron. The ensuing process is like watching a ballet between colors.
This is an example of "let paint be paint", as there is no way to control the ultimate outcome.
I still haven't figured out how to use the ferrous "wrong" so it rusts no matter how much water I'm not supposed to use... any suggestions?
Another fascinating push-pull discovered originally by accident: sumi ink (lacquer-finished) and watered down acrylic hate each other in the most loving way.
What happens when you use graphite across wet paint?
I use liquid acrylic for this technique; it will drag the paint, for a while, but then become graphite once the paint is off the pencil tip. See example.
What happens when you whack the painting surface off the ground?
In the case of acrylic--which has some weight to it--if you learn to control the hit it will produce teardrops or beading that differs immensely from simple "paint runs". This isn't for the shy, though: if you miss a dead-edge hit, expect to destroy all corners and edges of your surface.
I do hundreds of media experiements, as I am fascinated with the materials, in and of themselves. Some work and I keep them; some don't, but at least I know not to try that one again.
