This is a precious antique lamp by the Müller brothers, renowned as masterpieces of interior lighting decoration from the Art Nouveau and Art Deco periods. The Müller brothers, originally from the Moselle region on the French-German border, trained in glassmaking under Gallé after being evacuated during the Franco-Prussian War, and went on to become masters of Art Nouveau glass. This lamp is made using vitrification-colored glass, which they focused on producing from around the 1910s to the 1920s. (Acid signature is present.) The decoration used on this lamp's shade is a representative technique of Art Nouveau and Art Deco glass called vitriofication in Europe. During production, colored glass powder is sprinkled onto the glass, creating a blend of various hues. The form is pâte de verre, which cannot be mass-produced as each piece is created by crushing a mold. Combined with the soft curves and the calm colors of vitriofication, it possesses elegance within its simple, solid form. The base frame is made of bronze/brass. The vitriofication colored shade glass is beautiful, with its warm orange tones and distinctive, glamorous form. The angle of the shade is adjustable. The wiring and plug have been newly changed to domestic specifications. It uses an E17 bulb, and one bulb will be included. Size: Approximately 45cm in height, 14cm in base diameter.
