| The History of Crystal | |
|
The history of crystal glass is closely tied to the development of the room chandelier. Chandeliers were originally candle holders and were hung from the ceiling to illuminate a room - and reduce the risk of fire. In the late 17 th century, a process of casting glass prisms was invented. This glass was easy to produce, relatively cheap, and much easier to work with than real rock crystal that had to be mined and processed. Brand new models of chandeliers were soon being produced that used this glass, which was hand-cut and polished into different shapes and angles to increase candle power light. Today's chandeliers and ceiling fixtures use crystal glass in much the same way. The use of crystal helps create a visual focal point that draws the eye and suggests a romantic, magical intimacy that other types of lighting simply cannot reproduce. A new trend in the use of crystal is in table and floor lamps, and in the application of decorative crystal directly to the frame or body of chandeliers, lamps and other fixtures. There are many different types of crystal available today in a wide range of styles, cuts and price points.

Italian Crystal (Legacy, Venetian) Mass produced, this entry level crystal is modestly priced. It is cut
and polished like more expensive grades, but lacks the high optic
quality and precision facets. A good bet for consumers looking for high
value and more for less. Not real crystal glass at all, rock crystal is just that – crystal rock that is mined, not manufactured. It cannot be mass produced. Each rock crystal is completely unique, created by geological events and pressures taking place over millions of years. Authentic rock crystal bears a unique mark from this process, and can be identified both by visual appearance and by touch – it remains mysteriously cool to the touch no matter what the surrounding temperature. Raw quartz is mined in only a few remote locations. Rocks are hand selected, then ground, cut and polished entirely by hand – a laborious process. Polishing one piece can take a week or more because of the natural complexity of the rock material, and the rejection rate for imperfect pieces can be 12 to 1 or more. Used extensively until crystal glass manufacturing methods were invented, rock crystal is generally seen today in specialty lighting fixtures and custom designs. |
