Burlwood sometimes looks like a sylvan version of marble. Sometimes it's a combination of color, figure and voids. Sometimes it's random cravasses and 'fault' lines, and often it's combinations of all of the above.
This piece of Apple tree, turned to look like a Native American pot, is really an excuse to expose the inner beauty of burl wood, the apple of my eye.
Burlwood, while not a rarity, doesn't occur too often in nature. For this reason, high-end furniture makers would cut the burls into veneers and cover panels and chests, in order to maximize the beauty.
