Soda Ash

Soda ash, known chemically as sodium carbonate (Na2CO3), has been in use for thousands of years. Soda ash occurs in many kinds of mineral waters and in mineral deposits of certain springs and lake brines.

History Of Soda Ash

About 50 million years ago, volcanic activity, decaying plant matter, and climate change caused the evaporation of a large lake, leaving behind the world’s largest trona deposit located in Green River, Wyoming.

Natural vs Syntethic

Synthetic soda ash is made using either the Solvay or Hou process and contains a number of different chemicals. Both methods leave behind byproducts and require either seaside discharge or waste beds to catch leftover impurities.
