Solvay process - Wikipedia

The Solvay process or ammonia-soda process is the major industrial process for the production of sodium carbonate (soda ash, Na 2 CO 3).The ammonia-soda process was developed into its modern form by Ernest Solvay during the 1860s. The ingredients for this are readily available and inexpensive: salt brine (from inland sources or from the sea) and limestone (from quarries).
