I would welcome any opinion on the manufactures of this strange large piece of glass that I acquired last week. Believe me I have tried all the links and sources that I have picked up since joining this forum to no avail. The piece measures in 34.5cms diameter and stand 5-6 cms in height. The underside in decorated with a white spatter glaze that stands proud of the glass. There is a ground pontil. The actual rim of the vase in a not “level” and has a very handmade look about. It came in a box of vintage Bohemian glass although I have not seen anything Bohemian that resembles it. Any ideas?
