The scale is called hardness.
Mohs hardness scale is a measure of how well a mineral resists scratching. It ranks minerals on a scale from 1 (talc, very soft) to 10 (diamond, very hard). By testing the ability of one mineral to scratch another, we can determine their relative hardness.

Hardness is a measure of how well a mineral resists scratching. This property is determined using the Mohs scale, which ranks minerals from 1 (softest) to 10 (hardest).
The measure of how well a mineral resists scratching is called hardness. Hardness is determined by the ability of a mineral to withstand scratching by another material. The Mohs scale is commonly used to rank the hardness of minerals from 1 (softest) to 10 (hardest).
The resistance to being scratched is known as hardness. Hardness is a measure of how well a material can resist scratching or abrasion. It is commonly measured using the Mohs scale of mineral hardness.
The ability of a mineral to resist scratching is called its hardness. This property is commonly measured using the Mohs scale of mineral hardness, which ranks minerals from 1 (talc) to 10 (diamond), with each level representing a specific ability to scratch softer materials. The higher the number on the scale, the harder the mineral. Hardness is an important characteristic used in identifying and classifying minerals.
It is just simply hardness.

A minerals hardness is its relative ability to scratch or be scratched by other minerals. Diamond, for instance, can scratch all other minerals because of its hardness. Streak is the color of the mineral when powdered. This is usually accomplished by the streak test (swiping the mineral across an unglazed porcelain surface) which reveals a mineral's streak color, which may differ from the color of the specimen being tested.
The hardest substance in a rock would be the hardest mineral of which the rock is composed.
The r value in mineral wool insulation indicates its thermal resistance, which measures how well it can resist heat flow. A higher r value means better insulation and can help reduce energy costs by keeping buildings warm in winter and cool in summer.
