Hi all.................I found a piece tri-shaped IVIMA glass 5 or 6 years ago. It is 5" across and 2.5" tall and weighes 45ozs. It has a ground and polished base with their acid stamp. Last year I found a similar piece, and maybe related!? Or is this completely different? Scandinavian? The glass is 2.5"tall and 6" long and weighes 31ozs. It has ground and polished bottom but no markings. Any and all help will be greatly appreciated!........................Jerry
