Boron was discovered by Joseph L. Gay-Lussac and L. J. Thénard in 1808 that was around 60% pure. The pure form of boron was isolate by Henri Moissan (French chemist) in 1892 and then in 1909, almost 100% pure boron was isolated by Ezekiel Weintraub. The name borax has been originated from buraq (Arabic) and burah (Persian) meaning “white” [1].
