Mohs scale of hardness
Mohs' hardness, (Ritz hardness), introduced to mineralogy by
F. Mohs 1822 and still the standard and functional method for
determining hardness today acc. to ten degrees of hardness, each
degree of hardness being represented by a frequently-found mineral.
Each mineral classified in this hardness scale (Tab.) can leave a
scratch in the previous one, and is itself scratched by the mineral
next-higher on the scale. If an unknown mineral is scratched e.g.
by apatite (hardness 5) and if it can even be scratched by fluorite
(hardness 4), then the material has a hardness between 4 and
5. The degree of hardness of the minerals are so large that the
direction dependency of the minerals (with the exception of distene
with hardness degrees of 4 and 6) is not significant. Minerals up
to hardness 2 can be scratched with a fingernail; up to hardness 4
they can be scratched using a knife, whereas window glass can be
scratched by all minerals with a hardness > 6.
