This medium-sized bowl is a good example of Black Oak. It has a raised rim. This finish is food safe if you care to use it to display or serve food products. Julie just burned a very cool pattern of oak leafs and acorns around the raised rim. Now it is a collector's item! WOOD: Black Oak; DIAMETER: 8 3/8"; HEIGHT: 3 5/8"; WEIGHT: 12 Ounces.
