Lithyalin glass

An opaque Bohemian glass that looks like marbled stone, invented by Friedrich Egermann.
Friedrich Egermann (1777–1864) of Nový Bor patented Lithyalin in 1828. It was fashionable in Biedermeier homes and imitated precious stone vases. Examples are in the Museum of Decorative Arts in Prague and the Corning Museum of Glass.
Materials: Opaque glass with marbled colour layers
Manufacture: The glass was blown and cut in facets, and the surface treated with metal salts that produced the veining.
The veining in red, brown and green like agate or jasper.
The sharp cut facets that betray that it is not stone.
