Bohemian-Czech glass is a decorative glass made in Bohemia and Silesia starting the 13th century. In the 17th century, Caspar Lehmann, gem cutter to Emperor Rudolf II in Prague, adapted to glass the technique of gem engraving with copper and bronze wheels.
Bohemia was a part of the former Czechoslovakia, now known as the Czech Republic, and was famous for its beautiful and colorful glass. The history of Bohemian glass started with the abundant natural resources found in the countryside. Bohemian glassworkers discovered that potash combined with chalk created a clear colorless glass that was more stable than glass from Italy. This Czech glass could be cut with a wheel. Bohemia became famous for its excellent cut and engraving.
