Borax, a combination of sodium, boron, and oxygen, is a natural substance mined from the earth in its crude form, found in abundance in the deserts of California and Nevada.
Powdered borax is white, consisting of soft, colorless crystals that dissolve in water. Borax is an ingredient in many detergents, cosmetics, and enamel glazes. The trademark 20 Mule Team Borax is named for the method by which borax was originally hauled out of the California and Nevada deserts.
