Get Better Rock Tumbling Results with Mohs Hardness

How to Assess Hardness In 1812, Friedrich Mohs, a German mineralogist, developed a simple test for determining the relative hardness of rocks and minerals. He selected ten different minerals with a range of hardnesses and assigned hardness numbers to them. The softest mineral was said to have a hardness of 1.

Streak Test for Minerals

Streak plates usually have a Mohs hardness of between 6.5 and 7. Many minerals are harder than the streak plate. Instead of leaving a powder behind when dragged across a streak plate, they will scratch the streak plate or fracture into small pieces. Minerals that are harder than the streak plate are said to have "no streak" or a "colorless streak."

Hardness of Materials

The hardness of a material is measured against the scale by finding the hardest material that the given material can scratch, or the softest material that can scratch the given material. For example, if some material is scratched by topaz but not by quartz, its hardness on the Mohs scale would fall between 7 and 8. Indentation hardness.
