Lot #9: Art Deco Uranium Glass Torchiere Floor Lamp Light Reactive Aladdin Alcacite Glass Shade Trilight Working Glass Body 63"

Sound clean original condition Works fineDeveloped in 1938Alacite glass was the creation of Henry Hellmers and in his words was described as, "an opal glass." It was described in Aladdin advertising material as, "A startlingly beautiful lamp base, and pedestal material, which resembles many of the semiprecious mineralites in texture, and has much of the softness and tone of mineral(genuine )-the only color in which it is available."Originally Alacite glass contained Uranium oxide as a coloring agent, but its use was banned by the government in 1942 because of the development of atomic weapons in the war effort. You will often hear the terms "old formula" and " new formula" used in reference to lamps made of Alacite. The old formula contained the Uranium oxide, and will glow a yellow green color under a black light, while the new formula without the Uranium oxide will not. Uranium oxide was also a constituent of yellow moonstone and some green Washington Drape lamps. Both will glow brightly under black light.
