Hi Carolyn, it's good you have an enquiring mind!

Could I suggest you start a new topic with your question 'What is Uranium Glass' in the Glass Section of the board? Unless the moderators think it would be better in the Cafe?
On the ewer front, Chuggys piece is slightly different to the other ewers I've seen inasmuch that it has a conical shape with a flattened base. The rounded base shape in this style is more common, and I'd hazard a guess that theres too many of them about to be Gaspari... :?
Having said that, Chuggy's got a good eye, so maybe I'm wrong. :x
