I'm not sure if this is red or brown mallee burl, but it certainly is a fine piece of wood. It is 20" x 10" x 3" deep. The wing thickness tapers from 1/4" at the edge to 3/8" where it meets the bowl. This was the HARDEST piece of wood I've ever turned; it took nearly two hours to rough shape the bottom. I think I spent as much time sharpening as turning.
