STEEL PENCILS FOR MOHS SCALE HARDNESS TEST
This tool is used to perform a scratch test on materials to determine Mohs’ hardness of the surfaces (scale ranging from 1 to 10 where the Talc is
softest -Mohs 1-while Diamond is hardest -Mohs 10-).
To use it, simply scratch a smooth surface of the material to test with the picks of various indicated hardness.
As an example, if a No. 5 pick scratches the mineral, but a No. 4 pick does not, then your mineral’s hardness is 4.5.
Examples of materials on which industry uses this tool:
Concrete, Faucet finishes, Touch screens, Plastics and Glass materials, Countertop materials Flooring products, etc.
