History

Bohemia was a part of the former Czechoslovakia, now part of the Czech Republic, and was famous for its beautiful and colourful glass. The history of Bohemian glass started with the abundant natural resources found in the countryside.

. It was at that time when the term Bohemian crystal emerged for the first time in history to distinguish its qualities from the glass coming from other places. As opposed to usual perception this was non-lead. This Czech glass could be cut with a wheel.

Bohemia turned out expert craftsmen who artfully worked with crystal. Bohemian crystal became famous for its excellent cut and engraving. They became skilled teachers of glass-making in neighbouring and distant countries. By the middle of the 19th century, a technical glass-making school system was created that encouraged traditional and innovative techniques as well as technical preparation.

In the second half of the 19th century, Bohemia looked to the export trade and mass-produced coloured glass for shipment all over the world. Pairs of vases were produced either in a single colour of opaque glass or in two-colour cased glass. These were decorated in thickly enamelled flower subjects that were painted with great speed. Others were decorated with coloured lithographic prints copying famous paintings. These glass objects were made in huge quantities in large factories and were available by mail order throughout Europe and America. They were not fine art but provided inexpensive decorative objects to brighten up ordinary homes reverse glass painting was also a specialty of the Czechs. The image is carefully painted by hand on the back of a pane of glass, using a variety of techniques and materials, after which the painting is mounted in a bevelled wooden frame.

Among the items for which the Czech nation is still well known is the production of "druk" beads. Druks are small (3mm-18mm) round glass beads with small threading holes produced in a wide variety of colors and finishes and used mainly as spacers among beaded jewellery makers.
