This magnificent Art Nouveau vase with The precisely fitting glass insert from WMF (Württembergische Metallwarenfabrik) is an outstanding example of decorative metal art about 1900. The body made of silver-plated brass shows a filigree decoration of curved volutes and stylized floral elements that are typical of the Art Nouveau design language. The removable insert made of clear glass with its wave-shaped forged edge follows the lines of the mount exactly. The stand ring features the authentic WMF stamp of that era, complemented by the designations “BM” for Britannia metal, “I/O” for the strength of the silver plating and “OX” for the oxidized, artificially aged surface. The object has a characterful, dark aged patina and a lively, rainbow-colored tarnish layer inside the metal mount,.
