This coffee table by Lothar Klute consists of three separate glass panels that can be leveled using screws on the underside of the table. Lothar Klute's signature, LK83, is located on one of the legs in a visible area. A specific bronze alloy enabled the artist, Lothar Klute, to forge the bronze. The glass was produced using a special melting process and custom-made for the table.
