White Frosted Uranium Glass Lamp Shade, Tulip Ruffled Light Shade, Replacement Art Nouveau Glass for Sconce, Table Lamp, Fitter 55mm

An antique frosted white satin uranium glass lamp shade, dating to the early 20th century. Gented by its ribbed fluted motif, an elegant ruffled rim, and distinct green fluorescence when exposed to ultraviolet light.

Originating from the Art Nouveau period (circa 1900–1920), this style of glassware incorporates trace amounts of uranium dioxide, which reacts to UV light by producing a vibrant green glow. Popularized by European and North American glassworks during the Belle Epoque, this decorative technique created lighting components that visually transformed under different illumination.
