Mohs Hardness Scale: Testing the Resistance to Being Scratched

When testing the hardness or streak or other property of a mineral, the best way to test is on a freshly broken surface with expected luster that has not been exposed to weathering. About Hardness Tests. The hardness test developed by Friedrich Mohs was the first known test to assess resistance of a material to scratching.

Streak Test for Minerals using a porcelain streak plate

A few minerals will produce an odor upon being broken or powdered. For example, sphalerite releases an odor of sulfur when it is broken or powdered. Scraping it across a streak plate is a convenient way to conduct this test. Hints to other mineral properties can be obtained while doing the streak test.

How to test using tenacity. When testing for brittleness, one should scratch the specimen with a harder mineral or material, and see if the mineral leaves a fine powder. If fine powder is scratched off the mineral, it is brittle. If just a furrow is left without any fine powder, the mineral is nonbrittle.

Bentonite

Bentonite / ˈ b ɛ n t ə n ʌ ɪ t / is an absorbent swelling clay consisting mostly of montmorillonite.It usually forms from weathering of volcanic ash in seawater, which converts the volcanic glass present in the ash to clay minerals. Bentonite beds are white or pale blue or green in fresh exposures, turning to a cream color and then yellow, red, or brown as the exposure is weathered
