At the beginning of the 20th century, a new genre of drinking glass flourished in a small part of Bohemia: the "flower-shaped" liqueur glass. The technique was relatively simple; the floral decoration was enameled onto the outside of the bowl, often quite abstract, but when viewed from within, the flower bud revealed its full beauty. The glass was a beautiful, delicate luxury item. The production period was short; only between 1900 and 1910 did several glassworks in Bohemia produce these flower-shaped glasses. Identification and attribution are often difficult because they were rarely signed. Glassworks that produced this type of drinking glass included Fritz Heckert, Thersienthal, and Meyr's Neffe.
