CAESAR CRYSTAL BOHEMIAE Company specializes in manufacturing colorful cased crystal with a 24% PbO (lead oxide) content, which is made by connecting the layer of clear crystal and the layer of colourful crystal at temperatures around 800°C. The spectacular results of this manufacturing process requires the talent of the best and most skillful glassmakers. The demands of this time honored Bohemian tradition cannot be reproduced by any machines.
These traditional skills continue to be employed at CAESAR CRYSTAL BOHEMIAE glassworks today. Here, younger generations of glassmakers inherit the skill of the glass working and craft, from older glass masters.
The basic glass materials used in glass melting include glass sand, potash and lime stone. Glass shards are also added into a glass batch in the kiln. Typical Caesar colours are created by melting glass with a mixture of metal oxides. The current palette of colours includes Amber, Azure, Blue, Green, Red, Violet and more. A black colour, which is useable only for a few shapes and styles, is also melted for special design.
At each stage of the process the product is scrutinized to ensure it passes the stringent quality control standards. Only after that, a product is able to hold the CAESAR CRYSTAL BOHEMIAE brand. Products showing any imperfections, often invisible to the untrained eye, are often removed and crushed. In the case of white or ruby red crystal they can be recycled to be melted into molten glass again.
