My version is shown below. I have lots of burr oak around and it takes vinegar/steel wool ebonizing quite nicely. This piece started out as a vase about 6 months ago, but was to long to hollow without a steady rest which I haven't bothered to make yet. A few weeks ago I cut the bottom 1/3 off and started again. It was cracking, but that along with the interior that I left rough adds to it's character making it another rustic or primitive piece as well. A small void was created when a small burl popped out as well. It's about 8" tall and 6" wide at the top with 3 coats of danish oil and buffed. I will be doing more of this style.
