Thanks for the interesting posts. I'll need to qualify my Hoglund attribution, and hit the books. Of course, all this leaves me wondering, "If not Hoglund, then who?" The base treatment looks so much like mid-century Scandinavian factory glass (not studio, U.S. or Italian). I understand that Kaj Franck also used bubble technique in his work for a time, but one normally sees signatures on his stuff, too. Potato remnants or not, the inclusions (sand?) should lend a clue as to the maker. Finally, I should mention, for what it's worth, that the piece appears not to be leaded glass; not heavy.
