  • Mohs' Hardness Test Kit for Industrial Applications

    The kit contains 8 different Mohs' Hardness Points, from Mohs 2 through Mohs 9. These points are used in a 'scratch test' on the material. For example, if the number 6 point scratches a particular material, but the number 5 point does not, then your material has a Mohs' Hardness value of about 5.5.
