2013-9-1Quartz Sand is the key ingredient in making Glass. It is usually found near bodies of water and is only found alone. In 1839 the Frenchman Marc Antoine Augustin Gaudin succeeded in melting glass of pure quartz. Its advantage, compared to conventional, partially cristallized molten glass, was the fact that the melting point of quartz was much higher. Soon, it was used as a special glass for ...Discover More
