A Ceramic Tree

Some people grow trees in the forest, but me, I like to create them in my art studio here in Sedona, AZ. 
 This is a vase I made a while ago. There were two of them originally, similar, but each unique. Then, because I make my living this way, I sold one to a nice client who wanted a tree for her living space. 
You see, it is actually a vase, with a hollow inside that is glazed an elegant blue. Maybe it is the  sky reflected inward. You can use it to hold flowers, or just as a sculpture to enjoy.
This is a hand rolled piece, created from a slab of dark clay, which I inscribed with this bark pattern. It stands about nine inches tall. It is not  smooth, but has  texture, to which  I added an  iron stain for emphasis. As with all high fire clay, there is always the element of surprise, a variation in hues depending on where it was in the kiln, or how the kiln gods felt on that particular day . I have created a one of a kind ceramic tree.
But then, what in nature is exactly the same?
