The '''Mohs hardness scale''' for minerals has been used since 1822,<ref>http://www.gordonengland.co.uk/hardness/mohs.htm</ref> having been devised by [[Friedrich Mohs]] in 1812. It simply consists of 10 minerals arranged in order from 1 to 10. Diamond is rated as the hardest and is indexed as 10; talc as the softest with index number 1. Each mineral in the scale will scratch all those above it as follows:
 
−
#[[Talc]]
 
−
#[[Gypsum]]
 
−
#[[Calcite]]
 
−
#[[Fluorite]]
