kernite

Kern is also noted for its mineral wealth, including gold, borate, and kernite.

Kernite is used to produce borax which can be used in a variety of soaps.

The largest documented single crystal of kernite measured 2.44x0.9x0.9 m and weighed 3.8 tons.

More recently, kernite was also discovered at and is now mined in Argentina and Turkey.

Kernite is soluble in cold water and alters to tincalconite when it dehydrates.

These are mined industrially as evaporites, such as borax and kernite.

Kern County was the only known source of kernite for many years but is now mined in Argentina, Spain, and Turkey.

Economically important sources of boron are rasorite (kernite) and tincal (borax ore).

Kernite was discovered in 1926 in eastern Kern County, in Southern California, and later named for the county.

Boron does not appear on Earth in elemental form but is found combined in borax, boric acid, colemanite, kernite, ulexite and borates.

Kernite NaBO(OH) 3(HO)

Kernite, also known as rasorite is a hydrated sodium borate hydroxide mineral with formula NaBO(OH) 3(HO).

In one experiment simulating early Earth conditions, pentoses formed from mixtures of formaldehyde, glyceraldehyde, and borate minerals such as colemanite (CaBO5HO) or kernite (NaBO).

The most common sources of boron are tourmaline, borax, NaBO(OH) 8HO, and kernite, NaBO(OH) 2HO.

It is known to occur in over a hundred different minerals and ores, however: the main source is borax, but it is also found in colemanite, boracite, kernite, tusionite, berborite and fluoborite.
