I started with an abstract encaustic wax painting done on an 8"x10" clay board. I added a layer of shellac, then dabbed on shellac colored with PearlEx powder. I sprinkled on some silver PearlEx powder, then ignited the picture with a match. Once the burnable component in the shellac had burned off, I repeated the process. My PyroMuse loved it! Here's the picture. I'm not crazy about the brown spots, so I'll rub those with some PearlEx powder before I seal it. It's much more abstract after the burn process. I love the light blue just below the center - that's from the burn. They look like a field of blue flowers.
I'll be making a stop at Hobby Lobby to buy some more clay board tomorrow.
