This is a beautiful 11" tall vase. Antique Circa 1900 or so. Unmarked. Blown Molded similar to Loetz, Kralik & other Bohemian makers of the time. Polished top rim and flat molded bottom, no pontil. I have searched for hours and hours with no luck. Anybody ever see anything like it before or similar that would send me in the right direction. The base glass is a textured amber iridescent mottled design. With exterior decorated geometric triangles of different color iridescent shapes and lines throughout. Which are flattened within the surface of the glas not layed on. Any help would be greatly appreciated. It came from an estate with Durand, Kralik, Loetz, Quezal & Steuben glass items.
