Bruno Riedel, Steinschönau, Vase, 1940s, One of a kind. H. 31.4 cm. Colourless glass. Scenic representation of a family painted with transparent enamel. Signed lower right in the intermediate layer: Ried., Bruno Riedel developed his own technique. He drew the image on the glass body, then he filled the surfaces with coloured enamel, there was a second firing, then glass beads were dusted on the surface and heated again in the oven, creating the ice-glass-like surface.
