About Crystal


1. History of Crystal Glass

Around the 16th to 17th centuries, glassmakers in Venice succeeded in artificially creating ornamental glass, which had been possible only from crystal till then, from molten glass. That was the birth of crystal glass.


Glassmakers in Bohemia, Czech, developed techniques for cutting such crystal glass. The cutting gave glass wonderful refraction and unprecedented brilliance. The Venetian invention of crystal glass and the Bohemian cutting techniques revolutionized the world of glasswork. The royalty and the nobles, such as the Hapsburg in Vienna, used Bohemian crystal glass in the interior decoration of their elegant chateaux and earned the world's admiration. However, after Czech fell under the socialist regime after WWII, Bohemian crystal glasswork remained low-profile behind the Iron Curtain till 1992, when Czechs regained its independence.


Ever since, Bohemian crystal glass of Czech, which is of very high quality, has restored its glory and is now used in various ornamental products. To satisfy a broad range of demand, Bohemian glassmakers have developed a wide variety of applications ranging from interior decoration to clothing, bags, shoes and to accessories.


Czech is the worldfs largest producer and exporter of crystal glass. Bohemia is a center of glasswork with a history of over 500 years.





2. What is Crystal Glass?

gCrystal glassh refers to glass containing lead oxide, more than 17% of it according to the common definition. Glasses may be classified into various categories by constituents. Crystal glass is the most transparent of all kind of glasses.


Cut on the surface, glass increases brilliance and refraction. When the material is clear and transparent crystal glass, cut glass increases its brilliance. This is why in Western countries, Bohemian crystal glass is seen as the most valuable glasswork. Most of motifs specific to Bohemian cut glass come from ethnic lacework (In the medieval times, Bohemia was also a center of lace industry).


The adjective gCrystalh is used only for glasswork with crystalline clarity. It is a tribute to this glasswork that wonders us with its brilliance, luster, reflection, and refraction.


The reason why Bohemian crystal is still highly appreciated today in Western countries is said to be in the beauty specific to this material developed to its perfection - glass - and the exquisite ornamental techniques (cut and gravure) that matches the material.





3. Types of Rhinestones

Cheap rhinestones, produced in third countries, are all pressed stones. Pressed stones are produced by simply pouring molten glass into molds. They are poor in luster and shorter in life.


In Czech, manufacturers work on the best, finest crystal glass of Bohemia with proprietary cutting techniques to produce brilliance. They are called machine cut stones. After cutting, coating is applied to rhinestones to keep luster. The metal plating that covers the rhinestone is coated, too. Therefore, rhinestone and metal plating are both dry-cleanable.





4. Bohemian Crystal (Running Bright)

Originally used for interior decor, crystal glass is now used for accent on handbags, shoes, clothing, etc., often of top brands. Most of them are made by hand, hot, or high-frequency gluing. Any of these techniques may cost more than the cost of the rhinestone itself. Products with cheap, low-quality rhinestones are imported from third countries in abundance.


Kuboriki Lace has developed its products focusing on how it can use these brilliant Bohemian crystal rhinestones as part of fashion ornament. Through joint studies with local Czech manufacturers, the Company developed Running Bright.


With Running Bright, you can design your patterns freely according to the size of mesh fabric. With Running Bright, you can propose a desired pattern and choose the color of the rhinestones. You can design your patterns in narrow rolls or as motifs. You can use nylon mesh as well. By using nylon mesh fabrics, you can dye the base mesh fabric in desired colors (Dyeing is limited to reactive dyeing).





5. Lace & Crystal

These are a combination of high-quality Japanese lacework of Kuboriki Lace and Bohemian crystal glass. The noble atmosphere of the lacework is accentuated by rhinestones. Firmly caulked with brass fixtures, rhinestones rarely come off (as opposed to hot-fixed rhinestones which often come off while washing). They may be dyed.
