Cameo Glass is a highly decorative form of art glass created by layering different colours of glass before cutting, carving or acid-etching away the outer layers to reveal contrasting designs beneath. Perfected during the nineteenth century by renowned makers such as Émile Gallé and Thomas Webb & Sons, cameo glass often features intricate floral, botanical and landscape scenes. Antique cameo glass is celebrated for its artistic craftsmanship, technical complexity and exceptional beauty, making it one of the most desirable forms of decorative art glass.
