Mohsskála
Mohsskála, or the Mohs scale of mineral hardness, is a qualitative scale used to compare the relative hardness of minerals. Developed by Friedrich Mohs in 1812, it provides a simple framework for mineral identification in geology, fieldwork, and education. The scale orders common minerals from softest to hardest based on scratch resistance, rather than a precise numerical measurement of force.
The test works by scratch comparison: a mineral can scratch another if its Mohs value is greater
Limitations of the scale include its ordinal and non-linear nature; the hardness difference between successive minerals
Despite its limitations, the Mohs scale remains a foundational tool in mineralogy, widely used for quick identification,
