Pigmented structural glass, also known generically as structural glass and as vitreous marble, and marketed under the names Carrara glass, Sani Onyx, and Vitrolite, among others, is a high-strength, colored glass. Developed in the United States in 1900, it was widely used around the world in the first half of the 20th century in Art Deco and Streamline Moderne buildings. It also found use as a material for signs, tables, and areas requiring a hygienic surface. Over time, the trademarked name "vitrolite" became a generic term for the glass.
