Mohs' hardness scale

Mohs' hardness, (Ritz hardness), introduced to mineralogy by

F. Mohs 1822 and still the standard and functional method for deter-

mining 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, for example, can be marked by

apatite (hardness 5), and is still able to scratch fluorite (hardness 4),

its degree of hardness lies between 4 and 5. The degrees of hardness

for minerals are so large that the direction dependencies of the mine-

rals remain immaterial (with the exception of kyanite with the degrees

of hardness 4 and 6 in different directions). 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.
