Glass is formed by heating sand to its melting point. Objects are then either cast or blown to their desired shape and allowed to cool slowly. Glass is made from a mixture of sand and other materials. Just regular sand can be made into glass, but it must be heated to about 3,000 degrees Fahrenheit.
Most glass you encounter is silicate glass, which consists mainly of silica or silicon dioxide, SiO 2. This is the type of glass you find in windows and drinking glasses. The crystalline form of this mineral is quartz. When the solid material is non-crystalline, it is a glass. You can make glass by melting silica-based sand. Natural forms of silicate glass also exist. Impurities or additional elements and compounds added to the silicate change the color and other properties of the glass.
