The weekend I went to Denver, the GW had a 50% off sale. This glass piece must be missing a base because it looks like something used to be attached. Interesting that the plant looks like it is growing in there.
It must be a quality piece because it is marked Towle near the upper rim.
I couldn't discover what it really was, but for $5.00 I liked it enough to bring it home. Pressed glass diamonds or fan shapes make pretty patterns.
I really like it upside down, but the deep shapes make it too "busy" to be a cloche. Or not? Perhaps I'll look for something to use for a nob or handle and use it to cover tea time foods.
I seem to be collecting clear glass pieces lately. If you know what this is, let me know!
