Mohs hardness, rough measure of the resistance of a smooth surface to scratching or abrasion, expressed in terms of a scale devised (1812) by the German mineralogist Friedrich Mohs. The Mohs hardness of a mineral is determined by observing whether its surface is scratched by a substance of known or defined hardness. 2012/6/12Please tell me which one is the hardest and which one is the softest on the Mohs Hardness scale minerals and ores Bornite quartz bauxite galena sphalerite calcite pyrite garnet fluorite limestone copper steatite phosphorite hematite barite graphite gypsum feldspar chromite talc ___________ Rocks Basalt pumice gypsum sandstone chalk gneiss slate pink granite dunite shale ironstone siltstone
