I found myself particularly enthralled by the possibilities that something like an iron oxide could produce, so off to the art supply store I went in hopes of mining some metals.
I picked up small bottles of Golden's Micacious Iron Oxide, Iridescent Bronze and Iridescent Copper. To keep the glitz from overwhelming the bear, the metallic paints were brushed on thinly with lots of water added.
The bronze was quite the pleasant surprise, as when it was watered down, it separated into the bronze mica flakes, and an unexpected greenish-blue binder. That allowed me to float the greenish color around without overdoing the bronze. The copper and iron oxide didn't contain any surprise undertones, but were still fun to swirl around on the paper.
