History & Etymology

Late nineteenth-century trade card for Borax Soap. American Antiquarian Society Boron compounds may have been known for about 6000 years, starting with the Babylonians. The Egyptians, Chinese, Tibetans and Arabians are reported to have used such materials. The Arabs used the expression Bauraq (Persian burah) for a number of minerals including the now familiar borax (Na2B4O7•10H2O).

In 1702, Wilhelm Homberg (1652-1715) used borax, a substance generally thought to be artificially produced, to make a snow white powder he called sedative salt, (boric acid, HBO2). In 1747-8 Théodore Baron de Hénouville (1715-1768) demonstrated that borax is composed of the sedative salt and soda (Na2O).

Gay-Lussac & Thénard in France and Davy in England isolated the element within sedative salt in 1808.

On 21 June 1808, Louis-Joseph Gay-Lussac (1778-1850) and Louis-Jacques Thénard (1777-1857) in France announced their decomposing and recomposing boric acid. They called the new element bore and concluded that the radical should have a place beside Carbon, Phosphorus, and Sulphur. The following year Gay-Lussac proposed that gases combine exclusively in simple volume ratios.

Nine days later in England, on 30 June 1808 Sir Humphry Davy (1778-1829) presented a paper to the Royal Society likewise announcing the discovery of metallic Boron by heating boric acid and Potassium in a Copper tube for 15 minutes. In the Bakerian lecture, read on 15 December 1808, Davy proposed to name the new substance Boracium (note):

Bore / boracium was in English named boron, because of the similarity to carbon. Most of the other languages use the name given by Gay-Lussac and Thénard.

Chemistianity 1873
AMYAN
BORON, combined, used in forming Art Gems,
Is a metalloid of dull greenish-brown hue,
When burnt in Air, it forms Boric Oxide.
Boron, red hot, will absorb Nitrogen,
And, at the same time, emit bright white light.
J. Carrington Sellars, Chemistianity, 1873, p. 41
