1980s). Soda ash is very plentiful in the United States and is obtained almost entirely from natural sources of trona ore . However, it is more expensive to mine soda ash than to produce 50 percent caustic, so increased use of soda ash is not likely to occur unless the price of caustic is relatively high (Chenier 1992, DOW 1999).
