Mohs' scale of mineral hardness is named after Friedrich Mohs, a mineralogist. Mohs scale is ordered by hardness, determined by which minerals can scratch other minerals.[1] Rocks are made up of one or more minerals. According to the scale, Talc is the softest: it can be scratched by all other materials. Gypsum is harder: it can scratch talc

2017/09/10One 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.
