Vianne - Table lamp - Glass, Metal

Wonderful mushroom-shaped bedside lamp (or night-light) in multilayer blown glass from the famous French manufacturer Verrerie de Vianne (Lot-et-Garonne).
The dome and the base are made of satin marmoreal glass, displaying a magnificent palette of nuanced colors ranging from midnight blue/violet at the base to a bright warm yellow-orange at the top. When lit, the lamp emits a soft, enveloping and warm light.
The shade rests on a three-arm metal claw mount, adorned with stylized leaf motifs in the Art Deco style.
