Product Description
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. 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 hardness is 4.5. Then compare this against a table of minerals listing hardness values to aid in identifying the unknown mineral. The Deluxe Hardness Pick Set is unique in that, unlike other mineral hardness test tool that use minerals or crystal points, the picks are made of metals and alloys of hardness values equal to 2 through 9 on Mohs hardness scale. 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. 
 
A Mohs hardness kit is a straightforward tool for testing the hardness of materials like concrete. The kit typically includes a set of picks with hardness levels ranging from 1 (soft) to 10 (hard), based on the Mohs hardness scale.
 
Here’s how to use it:
 
1. Clean the Concrete Surface Ensure the surface is free of dust, dirt, or coatings, which could interfere with accurate testing.
 
2. Start with a Mid-Level Pick Since concrete typically falls between 4 and 7 on the Mohs hardness scale, start with a pick around level 5 or 6.
 
3. Scratch the Surface Hold the pick at a 45-degree angle and apply firm pressure to scratch the concrete surface.If the pick scratches the concrete easily, this means the concrete’s hardness is below the pick’s rating. Move to a lower number until you reach a pick that doesn’t leave a scratch.If the pick doesn’t leave a mark, increase the hardness level until you find one that does.
 
4. Identify the Hardness the hardness of the concrete is generally around the hardness of the first pick that leaves a visible scratch. If pick 5 doesn’t scratch but pick 6 does, then the hardness is approximately 5.5.
 
5. Repeat as Needed Check a few spots on the concrete, as hardness can vary slightly due to aggregate distribution.TipsAlways use a new or sharp part of the pick tip to ensure accurate results.For more precise results, test multiple locations, especially if the concrete is exposed to varying environmental conditions.This test helps determine the abrasion resistance and durability of the concrete, which is essential for choosing proper treatment methods or flooring finishes.
