This scale is a chart of relative hardness of the various minerals
Nickel has a hardness of 4 on the Mohs scale.
Coal, as an organic sedimentary rock, is not determined to have a hardness on the Mohs scale of mineral hardness.
The Mohs hardness scale rating for brass is around 3 to 4.
Stainless steel has a hardness level of around 5.5 on the Mohs scale.
Sulfur is a relatively soft mineral, with a hardness of 2 on the Mohs scale. It can be scratched by minerals with a higher hardness, such as calcite (3 on the Mohs scale) and fluorite (4 on the Mohs scale).
Friedrich Mohs is famous for creating the Mohs scale of mineral hardness. He formulated a scale of one to ten and assigned each mineral a value. This eventually became the basis for the Mohs scale.

It's called the Ore
This scale was proposed by the Austrian geologist Friderich Mohs.
The hardness of minerals is commonly tested using the Mohs scale, which ranks minerals from 1 (softest) to 10 (hardest) based on their ability to scratch each other. The scale was devised by Friedrich Mohs in 1812 and is still widely used in geology and mineralogy for identifying and comparing the hardness of different minerals.
The Mohs hardness scale is named after Friedrich Mohs, a German geologist and mineralogist who created the scale in 1812. It is used to determine the relative hardness of minerals by their ability to scratch each other.

The Mohs standard hardness scale that was developed by Friedrich Mohs (1773 - 1839).
Friedrich Mohs was a german geologist who classifying minerals by their physical characteristics rather than with the traditional method of chemical composition. The Mohs' Hardness Scale was invented in 1812, but the concept dates back to at least 300 BC.
