Mohs Hardness Test Kit

Mohs Hardness test kit is used to "scratch test" substances to determine their Hardness according to the Mohs' Hardness scale, which ranges from 1 to 10, where Diamond is the hardest at 10, while Talc is softest at 1. This kit can be used for:  Concrete  Countertop materials  Flooring products, etc  How to use hardness picks:  Scratch a smooth surface of your material with the picks of various indicated hardness. As an example, if a No. 5 pick scratches the material, but a No. 4 pick does not, then your material’s hardness is 4.5.   This kit includes: Four double-ended picks, color-coded, with eight points comprising 2,3,4,5,6,7,8, and 9 on Mohs’ hardness scale. Two Hardness Plates (of Mohs' hardness of 3.5 and 5.5) A 100 grit Grinding Stone to keep the points sharp. Rugged and compact molded Plastic Case. Hardness Table for 80 common Materials. Complete Instructions, customized for Industrial applications.
