Your cart is empty.This tool is used in industry to determine the Hardness of a material according to Mohs' scale. 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. A common use of this tool is in Concrete Hardness Testing to guide the technician in selecting the optimal abrasive to use in the concrete polishing. Other examples of industrial use of this Mohs' Hardness Test Kit - on touch screens, faucet finishes, and countertop materials. This kit comes packaged in a rugged molded Plastic Case with permanent Instructions, along with a Mohs' Hardness Table of common natural and man-made materials.

It works well. I use this almost daily. The tips are accurate with their hardness. Definitely recommend

works great. I added black & white streak plates along with other tests items to make it possible to identify rocks and minerals that I have collected over the years. much more accurate than trying to put a hardness kit together from everyday items

This is a great kit and really has helped me to identify a lot of minerals that I have found, at least within .5 accuracy. Unfortunately, it is the only game in town so you will over pay for it if you want it. This kit should sell for about, maybe, $80.00 tops. However, it does the job and, hopefully over time, I can justify the cost by the amount of use that I get out of it. It did arrive missing a magnet that was supposed to be included. That and the cost caused me to deduct a star from the rating. Hopefully some competition will arrive to get the price down to a more realistic level.

Decent kit here. The kit is the cheapest thing known to man though. I don’t know why they used this plastic that stinks and isn’t molded well. The kit works good though.

I use it to measure the hardness of rocks and geopolymeric concretes

Helps determine if you have a “soft†or “hard†concrete surface to grind. May save you money by finding out what diamonds to use on your floor grinder to polish concrete
