Physical Properties of Marble
Physical properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Marble like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The physical properties of Marble rock are vital in determining its Marble Texture and Marble Uses.
Hardness and Strength of Marble
The physical properties of Marble depend on its formation. Physical properties of rocks play an important role in determining its applications in various fields. Rocks are rated on the on the Moh's Hardness Scale which rates the rocks on the scale from 1 to 10. Rocks with hardness 1-3 are soft rocks from 3-6 are medium hardness rocks and 6-10 are hard rocks. The hardness of Marble is 3-4 whereas its compressive strength is 115.00 N/mm2. Streak is the color of rock when it is crushed or powdered. The streak of Marble is white whereas its fracture is not available. Luster of Marble is the interaction of light with the surface of Marble. Luster of Marble is dull to pearly to subvitreous. Marble cleavage is perfect. The specific gravity of Marble is 2.86-2.87. Marble is opaque in nature whereas its toughness is not available. You can also know all the list of rocks in Opaque Rocks, Translucent Rocks and Transparent Rocks.
