The manufacture of glass is one of the most important uses of sodium carbonate. When it is combined with silica (SiO) and calcium carbonate (CaCO) and heated to very high temperatures, then cooled very rapidly, glass is produced. This type of glass is known as soda lime glass

Sodium carbonate is also used as a relatively strong base in various settings. For example, sodium carbonate is used as a pH regulator to maintain stable alkaline conditions necessary for the action of the majority of developing agents. It is a common additive in municipal pools used to neutralize the acidic effects of chlorine and raise pH2 In cooking, it is sometimes used in place of sodium hydroxide for. These dishes are treated with a solution of an alkaline substance in order to change the pH of the surface of the food and thus improve browning.
