  • Mohs Scale of HardnessMineralogical Society of America

    The Mohs hardness scale was developed in 1822 by Frederich Mohs. This scale is a chart of relative hardness of the various minerals (1softest to 10hardest). Since hardness depends upon the crystallographic direction (ultimately on the strength of the bonds between atoms in a crystal) there can be variations in hardness depending upon
