This vase/hollow form was turned from fresh wood I found at my local firewood supplier, he couldn't tell me what tree it was from, but it was kindly identified by Freddie Hicks as Black Locust.
It was the first time I tried to turn a hollow form, and since I don't own a hollowing tool, it was done with a simple deep fluted bowl gouge, spindle gouge, and a round nose scraper for finishing inside.
The vase has some bark inclusion on the other side, but I chose this picture to display it because it shows better the form or the vase.
Although it was turned from fresh wood, the fibers of this wood are so dense and heavy, I thought it was dry, and so I finished it, but since I took it indoors with me, it has warped a little, but didn't crack at all, and it still looks great on display.
I have also turned later on a companion bowl from the opposite side of the same lumber, and I will post a picture of it as soon as it's finished.
Update:
My parents came to visit me in Italy the last weekend, and my mother fell in love with this hollow form and the sister bowl I made from the other half of the log, so I gave them to her, but I forgot to take pictures of the bowl, sorry about that.
