Art Deco Glass Lamp Shade Ruffled Tulip Light Cover Yellow Cadmium Selenium Opalescent Glass Globe Replacement for Pendant Table Wall Lamp

This glass lamp shade is an authentic Art Deco period lighting component, featuring a diamond-patterned yellow glass body and an opalescent ruffled rim. When exposed to 365nm ultraviolet light, the selenium-cadmium glass mixture produces a distinct red-orange fluorescence.

Dating to the mid-20th century, this piece represents typical European art glass manufacturing techniques from the Art Deco era. The incorporation of cadmium and selenium compounds in the batch allowed glassworks to achieve rich yellow to amber hues, which react dynamically to specific wavelengths of light.
