Abenakiite is a mineral named after an Algonquian Indian tribe of New England, ranking 4 to 5 on the Moh's scale of mineral hardness.
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 of mineral hardness is named after Friedrich Mohs, who developed it. The Rockwell scale of metal hardness is named after Hugh and Stanley Rockwell, who created the machine that measures it. Hugh and Stanley Rockwell aren't directly related to each other. The Shore Durometer scale for measuring the hardness of elastomeric materials like rubber is named after Albert Shore, who invented the measuring device called the durometer.
Diamond, with a hardness of 10 on the Mohs scale.
Talc is the softest mineral on the Mohs hardness scale, with a rating of 1. It is commonly used in cosmetics and as a lubricant.
The softest known mineral is 'TALC'. The hardest known mineral is 'DIAMOND' (according to Friedrich Mohs scale)
The fourth mineral on Mohs' Scale of Hardness is fluorite. It has a hardness of 4 on the scale.
Diamond is the hardest mineral known.
It's called the Mohs scale of mineral hardness.
Ruby, a variety of the mineral corundum, has a hardness of 9 on the Mohs scale of mineral hardness.
The hardest mineral is diamond, and the softest mineral is talc.
