This piece is incredibly heavy, 1138g and is 6.25" (160mm) in height.
Forgive my total ignorance when it comes to Pate de Verre. I have read all about the technique of how it is made, but still don't really 'get it' I do know that this has a totally different feel to any blown glass I have handled, but I have never handled Pate de Verre.
There is an outline of where there was sticker/label and, whilst photographing, I discovered it is signed. Illegible, of course

I'll let the photos do the talking before I make a complete fool of myself and look forward to any help.
