Borax (mineral) - Wikipedia
Borax (Na2B4O5(OH)4 · 8 H2O[2]) is a borate mineral found in evaporite deposits of alkaline lacustrine environments and as a surface efflorescence in arid regions. It is the chief mineral mined from the deposits at Boron, California and nearby locations, and is the chief source of commercial borax. [5]

In evaporite deposits, salt lakes, playas, and efflorescences on soils in arid regions, in solution in hot springs. Melting point: 878 °C. The melt dissolves numerous metal oxides. Loses 5 mol of water when heated to 100°C, another 4 mol when heated to 150 °C, and the last mol at 400 °C. Rapidly dehydrates in air to tincalconite.

Borax Mineral Information and Facts, Sources and Ores of Borates
Borax is brittle, vitreous, resinous or earthy; is translucent to opaque. On exposure to the air the mineral loses water and tends to become white. The principal method of occurrence of the mineral is as a deposit from salt lakes in arid regions, and as incrustations on the surfaces of alkaline marshes overlying buried borax deposits.
