Swung/pulled glass vase

So I don't get typecast as a glassware collector based on recent posts. I have a large factory and studio art glass collection, but rarely add to it any more due to lack of space and several cats who have broken a few of my favorite pieces. But... I had to buy something at a thrift shop today to get my total high enough to use my credit card and settled on this. It is 6" x 4" at the top and 2 3/4" at the bottom. The glass has kind of an oily, smooth feel to it and handling it is quite sensual. No marks and I don't expect anyone to identify the maker. I live in a university town and the uni has a very productive art glass program so it is not unusual to see small pieces like this floating around. Of course, it could be "Made in China" too, but a pretty little thing anyway, I think.
