mohs scale

The Mohs scale is a chart of the relative hardness of the various minerals from softest to hardest. The scale was developed in 1822 by Frederich Mohs. Since hardness

The Mohs Scale is shown below, using commonly known minerals to represent each degree of hardness: Talc; Gypsum; Calcite; Fluorite; Apatite; Feldspar; Quartz 

Mohs Hardness Scale The Mohs scale of mineral hardness is a qualitative ordinal scale that characterizes the scratch resistance of various minerals

Mohs hardness scale was devised in 1812 by Friedrich Mohs and has been the same ever since, making it the oldest standard scale in geology.

Note 2: Contrary to what one might expect, there is no apostrophe in "Mohs" — the name is a reference to the Mohs scale of mineral hardness, named for Friedrich Mohs. Grammatically speaking, you could put an apostrophe in the title in the sense that it's someone's scale, but if you did that, it would read "Mohs' Scale". And that's apparently
