What is the compound name for the product we know as Borax? (Laundry additive, etc.) Couldn't find it on the Borax site.

hydrated sodium borate Chemistry: Na2B4O7 -10H2O, Hydrated sodium borate. Class: Carbonates Subclass: Borates Uses: an ore of boron and as a source of borax (a cleaning agent and useful industrial chemical) Specimens Borax is a complex borate mineral that is found in playa lakes and other evaporite deposits. The basic structure of borax contains chains of interlocking BO2(OH) triangles and BO3(OH) tetrahedrons bonded to chains of sodium and water octahedrons. Most old mineral specimens of borax are chalky white due to a chemical reaction from dehydration. They have actually altered (at least on their surface) to the mineral tincalconite, Na2 B4O7-5H2O, with the loss of water. This kind of alteration from one mineral to another leaves the original shape of the crystal. Minerologists refer to this as a pseudomorph, or "fake shape", because the tincalconite has the crystal shape of the predecessing borax. Borax is directly deposited in arid regions from the evaporation of water in intermittent lakes called playas. The playas form only during rainy seasons due to runoff from adjacent mountains. The runoff is rich in the element boron and is highly concentrated by evaporation in the arid climate. Eventually the concentration is so great that crystals of borax and other boron minerals form.

You reminded me of the Borax coms during Death Valley Days hosted by the Grand ol' Man, Mr. Reagan. Dave S
