Traditionally, the glass was melted in furnaces from the raw ingredients of sand, limestone, soda, potash and other compounds. The transformation of raw materials into glass takes place well above 2000°F (1400 K); the glass is then left to "fine out" (allowing the bubbles to rise out of the mass), and then the working temperature is reduced in the furnace to around 2000°F. "Soda-lime" glass remains somewhat plastic and workable, however, as low as 1000°F.
Glass blowing involves three furnaces. The first, which contains a crucible of molten glass, is simply referred to as "the furnace." The second is called the "Glory Hole," and is used to reheat a piece in between steps of working with it. The final furnace is called the "lire" or "annealer," and is used to slowly cool the glass, over a period of a few hours to a few days, depending on the size of the pieces. This keeps the it from cracking due to thermal stress.

Properties
Naturally occurring glass, such as obsidian, has been used since the stone age. Glass making instructions were first documented in Egypt around 1500 BC, when it was used as a glaze for pottery and other items. In the first century BC the technique of blowing glass was developed and what had once been an extremely rare and valuable item became much more common.
The materials definition of a glass is a uniform amorphous solid material, usually produced when a suitably viscous molten material cools very rapidly to below its glass transition temperature, thereby not giving enough time for a regular crystal lattice to form. A simple example is when table sugar is melted and cooled rapidly by dumping the liquid sugar onto a cold surface. The resulting solid is amorphous, not crystalline like the sugar was originally, which can be seen in its conchoidal fracture.

Why? Because they blocked this site without proper reason and after about one year of negotiation still have not given a proper reason nor proper instructions of how to fix any problems
