"Wmf Center In Iridescent Crystal "myra""
Art Deco centerpiece in iridescent art glass, with shades of blue, purple, orange, and gold depending on the lighting. Myra glass has been surface-treated with silver nitrate and metallic salts to create rich and varied iridescence. Manufactured by WMF (Württembergische Metallwarenfabrik), it was designed by Karl Wiedmann to rival, but not copy, the art glass produced by Tiffany and Loetz, produced between 1926 and 1936. Still bears the brand label.
