Friedrich Egermann

A key figure for innovative glass decoration in the mid-19th century, Friedrich Egermann (1777–1864) operated one of the countless “refineries” in Northern Bohemia that specialized in decorating glass from the factories. In the late 1820s, he became famous for his “Lythialin,” a glass with a marbled surface that resembles semi-precious stones. However, Egermann's greatest success was to stain glass vessels with a ruby color, beginning in the 1840s. The process was so delicate that Egermann's rivals broke into his workshop to steal his notebook in order to accomplish it themselves.

One of Egermann's early collaborators, Josef Lobmeyr, later became famous as the most important glass trader in Central Europe. He founded his company in 1823 in Vienna, and acted as a distributor, selling Bohemian glass. But because he also established contacts between artists and glassmakers, Viennese art exerted a high influence on Bohemian glassmaking throughout the 19th and into the 20th century.
