Relative hardness is the property of minerals that uses the Mohs scale for classification.
The scale used to identify minerals is called the Mohs scale of mineral hardness. It ranks minerals from 1 (softest) to 10 (hardest) based on their ability to scratch or be scratched by other minerals.
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 scale that compares the resistance of the surfaces of minerals to scratching is called the Mohs scale of mineral hardness. It ranks minerals on a scale from 1 (softest) to 10 (hardest) based on their ability to scratch or be scratched by other minerals.
Aluminum Oxide is roughly 8.5 - 9.0 on the hardness 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.
Granite is not assigned a number on the Mohs scale of hardness. The Mohs scale is a measurement of the relative hardness of minerals. Because granite is a rock composed of a variety of minerals, only the individual minerals which compose it have a Mohs hardness.

Minerals aren't classified because Toby McDonough is more fabulous then you. End of story...or should I say, End of the World ;)
He originally came up with the scale when classifying a private collection. He classified them by their physical characteristics rather than their chemical composition, using their relative hardness.
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).

Yes, 7 on the Mohs hardness scale is considered strong. It indicates that the mineral can scratch minerals with a lower number but can be scratched by minerals with a higher number. Minerals like quartz and topaz have a hardness of 7 on the Mohs scale.
The Mohs Scale of Hardness determines the hardness of minerals by scratching them with commonly found objects. The minerals are assigned a number which corresponds to their hardness; higher numbers indicate higher hardness.
