Mineral Study Guide - Mohs Hardness


Caution - The accurate determination of relative hardness by testing the mineral against a glass plate requires a sample with a relatively sharp edge or corner, a firm grip, a significant downward force, and a steady hand. For example, if one does not exert enough downward force (a "wimpy" scratch), one might conclude that the sample is softer than a glass plate, when in fact it is not.

Mohs Hardness Scale: Testing the Resistance to Being Scratched


What is Mohs Hardness Scale? One of the most important tests for identifying mineral specimens is the Mohs Hardness Test. This test compares the resistance of a mineral to being scratched by ten reference minerals known as the Mohs Hardness Scale (see table at left). The test is useful because most specimens of a given mineral are very close to the same hardness.

How to Identify Minerals in 10 Steps - ThoughtCo


Sep 05, 2019· Hardness is measured on the 10-point Mohs scale, which is essentially a scratch test. Take an unknown mineral and scratch it with an object of known hardness (like a fingernail or a mineral like quartz.) Through trial and observation, you can determine your mineral's hardness, a key identification factor.

How to Test Hardness of a Mineral: 10 Steps - wikiHow


Jun 04, 2020· Then, look at the Mohs hardness scale to identify minerals that have the same hardness level. For example, if the copper penny (3) didn't scratch the mineral but a steel nail (5.5) did, you know that the hardness is between these. You can safely estimate the hardness of your mineral to be 4, which might be fluorite.
