Early vase by Daum. A clear glass base with a red glass layer on top and a green glass layer on top. In addition to partially etching away the glass layers, a lot has been ground away with the diamond wheel. In the flowers this is done very subtly and gradually and in the background with a torturelé (hammer) effect. In transmitted light the vase is mainly warm in color, and in incident light it is mainly green. A very special effect.
