Well how could I miss a post about 14" :oops:
Ivo may be right - see http://www.glassmessages.com/index.php/topic,4252.0.html
The object is different but the idea is the same, see the foot - the top (of yours) looks very much like items I have seen that take a light fitting - crazy sounding I know, but I wonder what it would look like with a shade?
Of course I think there would need to be a hole between the bottle and the clear glass fluted base, where the clear/gold flex would fit all the way through, the flex would come out one of the gaps
I have seen similar items and the clear glass looks strong and very level as if it were made as a base.
Just an idea of course
