Relative mineral hardness.
the mohs scale
Friedrich Mohs
This scale is correctly called the Mohs scale. Scientists use this scale to measure a rock's hardness or softness. They can discover how hard a mineral or rocks is and drill in to it and find out more about it.
The Mohs scale is used to determine the relative hardness of minerals.
Scientists use the hardness test, and more specifically Mohs Hardness Scale, named after a Freidrich Mohs, a German mineralogist. Mohs Hardness Scale test can scale from 1 to 10, where 1 is softest and 10 is hardest.
Mohs scale something like that sorry if it isn't accurate
By undergoing scratch test.
This scale was proposed by the Austrian geologist Friderich Mohs.
Talc is a mineral that ranks as the softest mineral on the Mohs Hardness Scale, with a rating of 1. This means that talc is very easily scratched by harder minerals.
It's called the Ore
Minerals have a fairly specific range of hardness, based on the Mohs hardness scale. The Mohs scale is based on the ability of a mineral to be scratched, or scratch, another mineral. Using the Mohs scale to determine mineral hardness is one test that can be used to help identify one mineral from others.
Diatomite has a hardness of around 5.5 on the Mohs scale of hardness.
