PACRAWFORD-L - Black Salt is crude potassium carbonate (Potash) used in making hard glass and soft soap. The pioneers cleared the land, burned the trees and retrieved the potash which was frequently their only source of cash. -- Tom Deagan, Pensacola, FL http://www.geocities.com/Heartland/Valley/1110/ http://www.pcola.gulf.net/~gdeagan/index.htm
