Never tried painting Lava before.. challenging, and having lots of tiny pits to take the yellow wash would help, but my textured caulking did not quite meet that challenge. Regardless! Onwards:
On the Left is the Red Orange, followed by Dark Brown, and a Final Black overlay. This was a fairly easy board to make and I think I will do another with a mainly dark red / black overlay, very small cracks, to make it a fairly well cooled lava flow.
