	Ulexite (Site not responding. Last check: 2007-10-09)
		Ulexite is a structurally complex mineral, with a basic structure containing chains of sodium, water and hydroxideoctahedrons.
		Ulexite is found with the mineral borax and is directly deposited in arid regions fromthe evaporation of water in intermittent lakes called playas.
		Ulexite is also found in a vein-like bedding habit composed ofclosely-packed fibrous crystals, also known as " TV rock" due to its unusualoptical characteristics.

		Ulexite is a Hydrous Carbonate Borate mineral, an evaporative deposit, and is a primary source of Boron.
		Some forms of ulexite are called "cotton ball", because they are round and resemble a cotton ball.
		It has a color ranging from clear to white, silky luster, transparent to translucent crystals, perfect cleavage, fiberous, when broken, a white streak, hardness of 2 and SG of 1.97.

		The present study concerns a work on the investigation of the effect of the dehydration temperature on the dissolution process of a boron mineral, ulexite, in sulfuric acid solution.
		First, the dehydration of ulexite was performed isothermally in an oven, and DTA and X-ray analysis were carried out to observe the structural changes in the mineral.
		The effect of the dehydration temperature on the dissolution rate of ulexite in sulfuric acid solutions was then investigated, using a batch reactor made of glass.

	SLU Physics - More Optical Properties of Ulexite
		Ulexite, a mineral comprised of parallel optical fibers, has a property of taking incident light and refracting it into one, two, or three circular cones.
		There is evidence that this may be due to the ulexite’s many fibers acting as diffracting slits.
		However, there is more compelling evidence that it may be due to leakage between adjacent fibers.
