The natural resource primarily used to make glass is silica, which is the main component of sand. Silica is commonly found in quartz and is processed to produce high-quality glass. To manufacture glass, silica sand is melted at high temperatures, typically between 1,700 and 2,000 degrees Celsius, transforming it into a liquid state. Other ingredients, such as sodium carbonate and calcium oxide, may be added to enhance certain properties, like durability and melting temperature. The resulting glass can be molded into various shapes and used in numerous applications, including windows, bottles, and electronics.
