We call it bodark down here. Other places call it osage orange, bois d arc, or even horseapple. One of the things I like about this wood is when you first turn it the color is a nice golden color, which as it is exposed to air longer turns into a great looking burnt orange. it was popular with Native Americans along the Mississippi for making bows from. It is an extremely hard wood. For someone turning this wood for the first time my advice is go slow, keep your tools razor sharp, and go slow. This wood due to it's density can crack on you really bad. Sometimes the cracks are deep and don't show up until you are almost finished with the piece. And, it can come apart on you. So just be careful if you want to turn some of this and it will be just as much fun as softer woods. I burned some lines on the top side of this piece just for added appeal. The outside diameter is 9 1/4" with an inside diameter of 5". The height is 2 1/2" and the vessel depth is 1 1/2". I think I am putting this post in the right location this time. I think the one I did earlier was in the wrong location. Sorry about that. Learning the site.
