The subjects received $5 a month and free food to be systematically poisoned. 12 volunteers were chosen. One additive was added per trial but he struggled to find non-adulterated products to add the poisons to. First to be tested was borax which tightened old meat which was starting to decompose. The borax was fed to the men in meat and dairy ...
At the age of 21, he left Wisconsin to prospect for mineral wealth in the American West, starting in Nevada. [4]In 1872, while contracting to provide firewood to a small borax operation at nearby Columbus Marsh, Smith discovered a rich supply of ulexite at Teels Marsh in Mineral County, Nevada, east of Mono Lake, near the town he would found ten years later, Marietta, Nevada, while looking ...
Borate ions occur, alone or with other anions, in many borate and borosilicate minerals such as borax, boracite, ulexite (boronatrocalcite) and colemanite. Borates also occur in seawater, where they make an important contribution to the absorption of low frequency sound in seawater. [1] Borates also occur in plants, including almost all fruits. [2]

Trimethyl borate is the organoboron compound with the formula B(OCH 3) 3 and a metal alkoxide. It is a colourless liquid that burns with a green flame. [1] It is an intermediate in the preparation of sodium borohydride and is a popular reagent in organic chemistry. It is a weak Lewis acid (AN = 23, Gutmann-Beckett method). [2]
The bead test is a traditional part of qualitative inorganic analysis to test for the presence of certain metals. The oldest one is the borax bead test or blister test. It was introduced by Berzelius in 1812. [1] Since then other salts were used as fluxing agents, such as sodium carbonate or sodium fluoride.

The formal negative charge of the tetrahedral borate center is balanced by metal cations in the minerals, such as the sodium (Na +) in borax. [1] The tourmaline group of borate-silicates is also a very important boron-bearing mineral group, and a number of borosilicates are also known to exist naturally.
