Mohs hardness scale. There is no standard hardness scale, but of the Mohs scale is the most commonly used. The Mohs scale of mineral hardness organizes the scratch resistance of various minerals. It does this by determining and ranking the ability of a harder material to scratch a softer material. It is named after its creator, Friedrich Mohs ...

The Moh's (Mohs) scale of hardness is the most common method used to rank gemstones and minerals according to hardness. Devised by German mineralogist Friedrich Moh in 1812, this scale grades minerals on a scale from 1 (very soft) to 10 (very hard). Because the Mohs scale is a relative scale, the difference between the hardness …

The Mohs scale of hardness is a measure used by mineralogists to classify the hardness of minerals. This scale, created by German mineralogist Friedrich Mohs in 1812, ranges from 1 (talc, the softest) to 10 (diamond, the hardest). By comparing the scratch resistance of various materials, one can determine where common objects fall on …

Minerals are chemically pure solids that occur in nature. The Mohs scale ranks minerals on a scale from 1 to 10, in which 1 is the softest mineral and 10 is the hardest mineral. Diamond is the hardest mineral, with a Mohs hardness of 10. Talc is the softest mineral, with a hardness of 1. The Mohs scale is ordinal, where the r…See more on sciencenotes
Use this kit for "scratch testing" substances to determine their Hardness according to the Mohs' Hardness scale, which ranges from 1 to 10, where Diamond is the hardest at 10, while Talc is softest at 1. While the Mohs' Hardness test was developed originally for testing minerals, the same concept can be applied to industrial materials ...

A simplified and crude test for hardness is to test whether or not a sharp corner or edge of a sample scratches (or indents) a glass plate. A numerical reference scale for hardness was devised by Mohs. A glass plate has a hardness of about 5 1/2 on the Mohs hardness scale. More information on hardness in mineral identification.

In 1812 (or possibly 1822), the Mohs scale of mineral hardness was devised by the German mineralogist Friederich Mohs (1773-1839), who selected the ten minerals because they were common or readily available. The scale is not a linear scale, but somewhat arbitrary. The "absolute" number below is a sclerometer measurement so it gives a more ...
