An Etched Glass Shade is a decorative lampshade featuring designs permanently engraved into the surface of the glass using acid etching or abrasive techniques. Popular during the Victorian and Edwardian periods, etched glass shades often display floral, foliate or geometric patterns that softly diffuse light while enhancing the elegance of the fitting. Antique examples remain highly prized for their craftsmanship and delicate decoration. *Related Terms*\ Acid Etching, Frosted Glass, Glass Shade, Opaline Glass, Victorian Lighting.
