Bohemian glass is renowned for its quality. It was sold in Saxony, France, Flanders. In terms of technology, only the equally well-known Venetian glass could compete with it, but the Czech masters were still able to get ahead of their Italian competitor. It should be noted that bohemian glass in eshop aleks-crystal.
The first Czech crystal piece was made in the 17th century. For the manufacture of Bohemian crystal, lead oxide and quartz sand are used. The process takes place at temperatures up to 1500 ° C. Some believe that the Czechs did not come up with anything special: just think, they included some kind of additives in the composition. But it is thanks to lead oxide that the glass turns into a sonorous, transparent and sufficiently strong crystal. And quartz sand contributes to resistance to chemicals.
Bohemian crystal (Bohemian glass) is represented not only by dishes. This material is successfully used for the manufacture of chandeliers. Thanks to professional processing, the lighting emanating from such chandeliers is quite versatile, it shimmers and scatters rainbow rays. Also, decorations, stained-glass windows and decorative elements are made from this material.
Varieties of Czech Crystal Sanded.
Various variations of polished patterns give uniqueness to each piece of a set or service. It should be noted that Czech crystal is cut by hand.

How to distinguish crystal from fake?
Lead content. According to European Union standards, real crystal contains more than 10% lead.
Crystal with more than 30% of this element is considered to be of high quality. If the product contains less than 4% lead, then it is just glass. Although in the Czech Republic itself, the bar has been slightly lowered. Here, products with 24% lead are considered first-class crystal. For comparison, in the United States, all glass products that contain more than 1% of this element are called crystal.
According to the coefficient of light refraction. Real crystal is characterized by iridescent tints and sparkle, which is absent in ordinary glass.
By weight. The products are not characterized by lightness, they have a significant weight, since lead oxide is used.
