... Mohs scale are as follows, and are num- bered from one to ten in ascending order of hardness: 1. Talc 2. Gypsum 6. Orthoclase feldspar 7. Quartz 3. Calcite 8. Topaz 4. Fluorspar 5. Apatite 9. Corundum 10. Diamond Referring to the list ...
... Mohs ' scale is still a standard tool in use throughout the world . Scratch hardness 1 represents the softest mineral , 10 the hardest . Some minerals show different hardness on different faces or in dif- ferent directions . In general ...
... Mohs scale with basic values underlined and bold ; E signifies the newer extended range Mohs scale . The original Mohs number 0.1 R , in midrange , and the new Mohs numbers ≈0.7 ( Vickers hardness number ) 1,3 Opt Oz low cycle fatigue ...
... Mohs scale , as it is called , the softest mineral , talc , has a hardness level of 1 because every other mineral can scratch it . In the middle of the Mohs scale is apatite , a rare mineral that can be cut as a gemstone and is used for ...
... Mohs ' scale . The German mineralogist Friedrich Mohs published his scale in 1822. From miners , he learned the idea of using scratch tests to compare minerals . His scale compares ten groups of substances from softest to hardest . From ...
... Mohs's scale of hardness does not permit the application of arithmetical statements to hardness , or that the scale does not make possible the formulation and verification of numerical laws pertaining to hardness . In point of fact ...

... Mohs scale , which assigns a value of 10 to a diamond and a value of 1 to talc , does not mean that diamonds are 10 times harder than talc par- Similarly , a grade of 10 on an orgaoleptic scale does not im- ply that the product tastes ...
... Mohs ' scale . Friedrich Mohs , a German mineralogist , learned from miners who rou- tinely used scratch tests to compare minerals . He published a scale in 1822 , comparing ten groups of substances , ranked in order of increas- ing ...
... Mohs scale needs some explanation. It was developed in 1812 by geologist Friedrich Mohs. He created a system for measuring the relative hardness of minerals. A rock or mineral with a higher Mohs value will scratch a rock or mineral with ...
