Bohemian crystal glass is world-famous. There is a company in Karlovy Vary that specializes in the production of this glass. In the Moser Glass Museum we took a closer look at the subject of glass production.<\/p>\n\n\n\n\n\n\n\n

About Bohemian crystal glass<\/h2>\n\n\n\n

Since the 16th century, Czech bohemian crystal glass has been traditionally produced in North and West Bohemia. Crystal glass is a colorless glass that often contains metal oxides or metal ions as additives.<\/p>\n\n\n\n

As for almost everything, there are precise definitions of when a crystal glass is a crystal glass. For example, a glass must contain certain additives, have a certain hardness and refractive index to be a crystal glass. Because of the special hardness of the glass, glass cutters are able to create beautiful products. The light refracts in the engravings and creates rainbow-like tones, which make the Bohemian crystal glass unique. The Bohemian crystal must contain at least 24% lead oxide.<\/p>\n\n\n\n

For many years there were products that advertised with their high lead oxide content to emphasize the quality of the glass. In the meantime, the toxicity of lead has been recognized, and the lead content is no longer the focus of attention. Although lead is hardly soluble in glass, it can be dissolved out by acetic acid, for example. Therefore, contact of lead crystal with food should be avoided.<\/p>\n\n\n\n

In Bohemia, the Karlovy Vary glassworks Moser has developed lead-free crystal glasses. For this purpose calcium carbonate in the form of chalk was mixed into the glass mass. These glasses also have the appropriate hardness so that the glass cutters can create true works of art.<\/p>\n\n\n\n
