Kernite

Kernite, also known as rasorite, is a hydrous sodium borate mineral with a monoclinic crystal structure. It typically occurs as colorless to white, tabular or prismatic crystals and is often found in arid environments such as desert playas. Kernite is an important source of boron, which is used in various industrial applications including the production of glass, ceramics, and detergents. Its name is derived from Kern County in California, where it was first discovered. Kernite has a relatively low hardness and can be easily scratched, making it unsuitable for use in jewelry. However, its economic importance and unique crystal habit make it a valuable mineral for collectors and researchers alike.
