►Origin of Borax Decahydrate




   Sodium tetraborate was first discovered in dry lake beds in Tibet and was


imported via the Silk Road to the Arabian Peninsula in the 8th Century


AD. Borax first came intocommon use in the late 19th century whenFrancis


Marion Smith's Pacific Coast Borax Company began to market and popularize a


large variety of applications.Borax is a component of many detergents,


cosmetics, and enamel glazes.  It is used to make buffer solutions in


biochemistry, as a fire retardant, as an anti-fungal compound, in the manufacture


of fiberglass, as a flux in metallurgy,neutron-capture shields for radioactive


sources, a texturing agent in cooking, as a precursor for other boron compounds,


and along with its inverse, boric acid, is useful as an insecticide.In artisanal gold


mining, the borax method is sometimes used as a substitutefor toxic mercury in


the gold extraction process. Borax was reportedly used by gold miners in parts of


the Philippines in the 1900s.

    Borax Decahydrate is chemically stable under normal storage conditions.


 It will slowly lose water of crystallisation if exposed to a warm, dry atmosphere.


Conversely, exposure to a humid atmosphere can cause recrystallisation at particle


contact points, resulting in caking.  When storing the product, care should therefore


be taken to avoid wide fluctuations in temperature and humidity, and to ensure that


the packaging is not damaged. Dissolved in water, Borax Decahydrate hydrolyzes


to give a mildly alkaline solution.  It is thus capable of neutralizing acids. It also


combines with strong alkalis to form compounds of lower pH. The relatively


constant pH of Borax Decahydrate solutions makes it an excellent buffering agent.
