The Deluxe Hardness Pick Set from Mineralab is unique in that, unlike other mineral hardness testing tools that use minerals or crystal points, Mineralab’s picks are made of metals and alloys of hardness values equal to 2 through 9 on Mohs’ hardness scale. And because the picks are made of metal, they are easily ground to sharp points which will not break off and which can be easily sharpened.
Why measure the hardness of a mineral? Because hardness is an important and quantifiable physical characteristic of a mineral, and in your effort to identify an unknown mineral, the hardness, if known, combined with other properties, can narrow your search to just a handful of possibilities.
How do you use the hardness picks? Simply scratch a smooth surface of your unknown mineral 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. Then compare this against the included table of minerals listing hardness values to aid in identifying the unknown mineral.
