== Mohs hardness scale ==<br />
The Mohs Hardness Scale is a qualitative scale that ranks [[minerals]] based on their scratch resistance. Developed in 1812 by Friedrich Mohs, it is widely used in geology, material science, and various industries.https://www.amfed.org/mohs-scale<br />
<br />
== The hardness scale ==<br />
The scale consists of ten [[minerals]], ranked from softest (1) to hardest (10). [[Talc]] is very soft and easily scratched. [[Gypsum]] can be scratched by a fingernail. [[Calcite]] is scratched by a copper [[Currency|coin]]. [[Fluorite]] is scratched by a [[knife]] blade. [[Apatite]] can scratch [[glass]]. Orthoclase [[Feldspar]] scratches window [[glass]]. [[Quartz]] can scratch [[steel]]. [[Topaz]] is harder than quartz. Corundum includes [[sapphire]](s) and [[ruby]](ies). [[Diamond]] is the hardest known natural material.https://www.gemsociety.org/article/select-gems-ordered-mohs-hardness/<br />
<br />
== Uses ==<br />
The Mohs scale is applied in various fields. In [[geology]], it is used for mineral identification. In [[manufacturing]], it helps select wear-resistant materials. In [https://wikipedia.com/Jewelry jewelry], it assesses [[gemstone]] durability. [[Industrial tools]] use the scale for [[abrasives]] and cutting equipment.https://geology.com/minerals/mohs-hardness-scale.shtml<nowiki/>7<br />
<br />
== Limitations ==<br />
While useful, the Mohs scale is not precise in measuring absolute hardness. It is based on relative comparisons, making it more practical for quick identification rather than scientific analysis.https://www.vedantu.com/geography/mohs-hardness-scale</div>Lunimaine
