Borax

Borax (also know as sodium borate, disodium tetraborate, and sodium tetraborate) is a white, crystalline compound. It is naturally occurring, and can be mined in some places like California. This alkaline substance has been used for numerous purposes through many centuries. It is perhaps best known as a cleaning agent, although it is also sometimes used in in tanning, and in manufacture of glass, metals (as a flux), porcelain, and enamel. The chemical formula of Borax (called tincal in its unrefined state) is Na₂B₄O₇•10H₂O
