Kernite: The borax mineral Kernite information and pictures

Kernite was first discovered in 1926 in the Kramer District in Boron, California, in an enormous, underground deposit. Almost immediately, its commercial importance was recognized and it became the most significant source of the chemical borax, becoming an even greater ore than the mineral Borax itself. Many more Kernite deposits probably exist deep below the surface in large borate deposits ...
