Soda ash, the trade name for sodium carbonate (Na2CO3), is a white, anhydrous, powdered or granular material. It is an essential raw material used in the manufacturing of glass, detergents chemicals and other industrial products.
Today, “natural soda ash” refined from the mineral trona is regarded as the standard for quality and purity and is also processed from sodium-carbonate-bearing brines. The Green River Basin of Wyoming is the world’s largest area for naturally-occurring trona. There is also “synthetic soda ash”, which is manufactured using a number of different chemical processes.
