Make Glass Sand
History doesn't show when people first began to Plaster manufacture or even who discovered how to turn sand into glass. What we do know is that the oldest pieces of manufactured glass are beads that date to around 3500 BC. Glass was primarily used as jewelry until the 16th century BC when artisans discovered how to fashion glass into vases and other art objects. The first written manual containing instructions on how to make and shape glass dates to 650 BC. Glass was so precious and hard to come by that glass objects were used as currency by ancient Romans, Egyptians and Greeks.

Recycled aggregates, sodium carbonate and calcium carbonate are heated together to glass processing machine. The sodium carbonate lowers the temperature at which sand liquefies and the sodium carbonate makes the glass sturdier. Glass made from this mixture is referred to as soda-lime-silica glass, and most manufactured glass is made from this. However, other chemicals and dyes can be added to make "specialty" glass. Blue dye added to liquid soda-lime-silica glass makes blue-colored glass. Pyrex makes its glass containers by adding the chemical boron oxide. Glass is shaped into an end product by pouring liquid glass into molds or floating it on molten tin and allowing it to cool. Artisans still shape glass by "blowing" it. A hollow pipe is dipped into liquid glass, as the artisan blows through the pipe the glass expands like a balloon. The artisan can then shape the glass by twirling the pipe and controlling how much air he uses.
