|How is it that non-transparent raw materials such as sand, limestone, and potash give us a product being as clear and shiny as the light?|
In general, most glass is made of three basic materials - silica based sand, crushed limestone and sodium carbonate - which are combined to form what's known as batch. The color and transparency of the finished glass depend on the composition of the batch (example: if you want a transparent glass, you have to use sand with higher content of silica).
Temperatures in excess of 2,500degrees Fahrenheit are then applied to the batch, causing a chemical and physical transformation that converts the opaque solid into a transparent hot liquid. In this molten state, glass can be molded and shaped into myriad forms.
The finished glass forms as the molten liquid is cooled. The decrease on temperature creates a molecular arrangement that produces a distinct 'glassy' state of matter that has the rigidity of a solid but a chemical structure similar to a supercooled liquid. Technically speaking, the molecules are arranged randomly as they would be in liquid, but the final product solidifies before the molecules have time to form ordered positions, as in crystals, metals, and many other solids.
Glass was invented approximately 4,000 years ago in the eastern Mediteranean, probably by a potter who inadvertently mixed the fused silica from his pots with alkaline ash in the hearth below his kiln.
|A perfect scientific explanation - but for us the miracle still exists!|
|Crystal remains one of the oldest, most fascinating materials of mankind and just as fascinating is the art of the glassblowers, cutters, engravers, and painters.|
|Only with fine crystal, because of its purity and brilliance can an artisan fully express his/her concepts. Master glassmakers have made these dreams come true.|
