Quartz sands, which are high in silica content, are used to make glass. When quartz sands are crushed they produce particles with sharp, angular edges that are sometimes used to make sandpaper for smoothing wood. Some quartz sand is found in the form of sandstone. Sandstone is a sedimentary, rock-like material formed under pressure and composed of sand particles held together by a cementing

Sand (silica or silicon dioxide) melts at 1710 °C, and sodium carbonate melts at 851 °C. These ingredients along with lime, CaO, make up a common type of glass known as soda-lime glass because it contains soda, lime, and silicon dioxide (Na 2 CO 3, CaO, and SiO 2) with the composition being about 25%, 12.5%, and 62.5%, respectively. There is no way to tell exactly when and how glass making
