Mohs scale of mineral hardness 77 AD. While greatly facilitating the identification of minerals in the field, the Mohs scale does not show how well hard materials perform in an industrial setting. Despite its lack of precision, the Mohs scale is highly relevant for field geologists, who use the scale to roughly identify minerals using scratch kits. The Mohs scale hardness of minerals can be commonly found in reference sheets. Mohs hardness is useful in milling. It allows assessment of which kind of mill will best reduce a given product whose hardness is known. The scale is also in use at digital electronic manufacturers, for
Marble Rocks one side to another. This gave the Gorge its local name- Bandar Kudni (meaning- Monkey's jumping place). The white marbles are predominantly rich in magnesium and are closer in hardness to soap stone. This softness allows them to be carved. The area also contains blue and brown colored marble.
