These pencils are used to try and
scratch a stone and observe if the pencils can scratch the gem. Since this is a
destructive method (it leaves a scratch), this test is mostly used on pieces of
rough or on a inconspicuous place on the gemstone. It is also suitable for
various other geological, construction, as well as industrial test &
research purposes.

The gemstone is tested with a pencil of
low hardness (starting at 4 or lower no. of hardness pencil) to try to put a
tiny scratch on the stone without applying pressure. If no scratch is observed,
one repeats this process with a pencil of higher hardness no. (in this case one
can use the no.5) and so on until one arrives at the pencil that is able to put
a tiny scratch on the stone.

For instance, if one could not scratch
the mineral with pencil no.5 but it would leave a scratch with pencil no.6 the
hardness of the mineral must be between 5 and 6 on Mohs scale.

Industrial Uses

To determine the hardness of a concrete
surface relative to Mohs’ hardness scale you must perform a scratch test. Start
by using the lowest number pick and continue up the scale until the concrete
begins to scratch and that is your numeric number of hardness relative to the
Mohs’ scale.

1 = Softest 10 = Hardest

Tooling Reference to Mohs’ hardness
scale:

2-3: Hard Tooling

3-5: Hard Tooling

5-7: Medium Tooling

7-9: Medium Tooling
