Crystal Glasses As Diamond Fragments

Thursday, 06 August 2009
crystal glassesCrystal is the decorative glass that is different from the other glass with the high concentration of lead oxide giving that famous brilliant shine. It increases the refractive index and color dispersion to the diamond purity, thus allowing breaking up into the rainbow colors as well as the diamond does. Baryta is sometimes added to give the increased index of retraction.

 

It is curious but such a fragile mineral originated as a result of wars. The military actions in Great Britain caused James I, the King, to forbid using wood in production, apart from shipbuilding purposes.

Glass production required high temperature and they set using coal for furnaces at glasshouses that would use wood previously as their main fuel material. And at that exact time, the unique effect of glass decolorizing was accidentally revealed, which assumed the higher index of refraction.

Plenty of experiments using various chemical additives resulted in 1676 George Ravenscroft, the glassmaker, developed the technology of the heavy and durable glass characterized by its brilliance, clarity and highly refractive quality with some lead oxide concentration. It ushered a new style in glassmaking and eventually made England the leading glass producer of the world. Lead oxide additives facilitated increase in index of refraction to the highest extent possible for that time. Besides, the lead crystal glass was resistant to acids and alkaline. Currently the world standard of the lead oxide concentration in crystal makes 24%, yet the technology invented by George Ravenscroft for the lead crystal has not undergone sea changes. Only the equipment has been sophisticated.

Later on, other additives were also discovered that furthered to modify the features of the plain glass and make it into the crystal, but with some different refraction and dispersion. Thus, apart from the lead crystal, there is baric crystal, and barium oxide is used to produce such crystal instead of lead oxide. Yet, definitely, the famous Bohemian crystal known as the best crystal in the world, is produced by adding potash calcium glass added to the glass mass to replace lead oxide or barium oxide.

Stained crystal then came out that is still popular in public. Crystal may change its color with various additive agents added to it. So, cadmium or gold compounds bring the red tint, while the silicon adds a pink color to crystal; cobalt gives luxury blue color, and copper-oxide provides the green of grass, while the manganese oxides bring the violet depth of the night sky. Among the colored crystal the pearl grey, amethyst and azure crystal made by the royal shops in Sevres, France.

There is another ever popular kind of crystal, so called frosty crystal. To gain the effect of frosty surface, the crystal item is treated by the hydrofluoric acid and as the result, the surface that previously not coated with the special acid-proof tar, becomes matte. The frosty crystal things appear stylish and superior, and they truly impress.

The technique of crystal treatment is the diamond cutting accepted from the ancient times. Using this technology, the items are treated with the rotating circles of the artificial diamond with the subsequent polishing by acids. As a result, we enjoy the trendiest option of the crystal that is opalescent like a diamond with all colors of the rainbow.

The crystal became popular in other countries in the end of XVIII, almost a century after George Ravenscroft developed his unique technology. The crystal dishware manufactured in old times in Russia for instance, are traced and chased by collectors, since it is of historical and artistic value as well.

In 1892 Daniel Swarovski invented a crystal cutting machine which was faster and more precise than hand cutting. And it was Swarovski's technology that has been used all wide and helps to draw vivid attention to crystal as both to the material to manufacture dishware from and to the jewelry. Swarovski Company now manufactures approximately 80% of all the glass gems for bijouterie, apart from the various eye-catching dishwares, bras and other items. Daniel Swarovski found crystal as one of the unusual and wonderful material and never intended to hide it for something else. His technology in fact is the promotion of crystal as the wonderful mineral as such but absolutely not because crystal resembles diamond. Yet, Swarovski's works made the crystal trendy, from jewelry to interior decoration items. Thanks to Daniel Swarovski, the use of crystal is widely practiced in all the spheres. It is used in paintings, household appliances and lightings, interior decoration and furniture. Crystal is also used in manufacture of bathroom equipment.

Currently various materials are marketed which are far less expensive than crystal. Nevertheless, the brilliance of the crystal is always in. Chic and decency of crystal pieces, their natural transparence is not feasible to replicate, thus crystal stays the mineral of all ages.
