The scale was introduced in 1822 by the German geologist and mineralogist Friedrich Mohs, in his Treatise on Mineralogy; it is one of several definitions of In the early 1800s, Friedrich Mohs, an Austrian mineralogist, developed a relative hardness scale based on the scratch test. The Mohs scale of mineral hardness (/ m o z /) is a qualitative ordinal scale, from 1 to 10, characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material..
