Bohemian crystal.
Bohemian crystal is considered to be the card of Czech Republic. Archaeological evidences testified the existence of glass-blowing in the Czech Republic since the IX century. Czech glass was popular in the XVII century and dominated the European market of chandeliers. Pure, colorless glass called «Bohemian crystal», produced at that time in Bohemia - perfect in their properties for cutting and engraving - had no equal in the market crystal glass. In 1724, the master of cut glass Joseph Palma was decorated with the royal order for producing chandeliers. The first chandelier production was discovered in a small village near the town of Prahen Kamenický Šenov in Northern Bohemia. These crystal chandeliers dominated in Europe until the middle of the XVIII century and greatly determine the evolution and future style of chandeliers in the world.
