Of the many silica-based glasses that exist, ordinary glazing and container glass is formed from a specific type called soda-lime glass, composed of approximately 75% silicon dioxide (SiO 2), sodium oxide (Na 2 O) from sodium carbonate (Na 2 CO 3), calcium oxide, also called lime (CaO), and several minor additives.
Glass can only be molded at very high temperatures. It completely melts/liquifies at approximately 1400 Â°C to 1600 Â°C depending on the composition of glass. Glass is made from a variety of substances, depending on the intent of use. Mostly sand, lime and soda are what most glasses are made of.
