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 (SiO2), sodium oxide (Na2O) from sodium carbonate (Na2CO3), calcium oxide, also called lime (CaO), and several minor additives.
