Hi Kristi,
forgot the trusty tennis ball as a size comparison.
No, its not that big, just 6 1/8" tall, 3 1/2inches across top, 3 1/4 inches wid base.
I suppose you would drink from it. Maybe it could be called a Chalice?
Also , quite interesting, ive never spent ages looking at it closely before,
but it must be all cut from one piece of glass! From top to bottom, nothings
attached, not the foot, not the collar around the base of bowl,
there must be hours and hours of work in it

Maybe thats a clue?
Andy
