Soda ash is most commonly used in:
- Manufacture of glass, where it reduces the melting temperature of the sand used in glass formation and helps in the 'workability' or shaping of glass articles such as tableware and float glass,
- Making soaps and detergents, where it is employed as a builder, or filler, to give a smoother surface,
- Production of chemicals such as sodium silicate, sodium bicarbonate and percarbonate, and sodium chromate and dichromate,
- Pulp and paper manufacture, water treatment, effluent treatment, metallurgy and drugs.
