Mohs Scale of Mineral Hardness ThoughtCo

· 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 of a diamond and that of a ruby is much

Rating Minerals on Mohs Scale of Hardness

· The Mohs scale is an ordinal scale, meaning that it is not proportional In terms of absolute hardness, diamond (Mohs hardness 10) is actually four times harder than corundum (Mohs hardness 9) and six times harder than topaz (Mohs hardness 8) For a field geologist, the scale works great A professional mineralogist or metallurgist, however, might obtain absolute hardness by using a

Mineral Study Guide Mohs Hardness

Background The hardness of a mineral is its resistance to scratching or indenting 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
