Volcano vase

I call this a Volcano Vase, just because it looks like a volcano to me. It is unsigned and, feels to me like a mass produced piece as opposed to a one off from a glass artist, but the grind where a pontil was removed (?) is a bit uneven, so maybe a one off. Bottom has been ground a bit to flatten it and polished. 8.5"hx6.25"lx4"w. Not much else I can say about it. Might be Italian... I like it, though, and keep it on my desk as a pen/pencil holder. I live near Illinois State University, which has a pretty good art glass program, so it could be a student piece. Any comments appreciated!
