Mohs scale song
Melodie: Sommaren är kort
In early 1800 th
Fred Mohs developed chart
That compared
Ten minerals
He began with talc
And worked it up to diamond
The chart is known today
As the Mohs
Scale of hardness
Talc
Talc is really soft
And gypsum scratches it
Calcite and flourite
Both get marks
From rough apatite
Orthoclase is hard
But quartz it cannot touch
Topaz and sapphire both
Are beaten
By diamond
With qualitative method
That compared
