Properties of Felsite

Physical Properties of Felsite

Physical properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Felsite like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The physical properties of Felsite rock are vital in determining its Felsite Texture and Felsite Uses.

Hardness and Strength of Felsite

The physical properties of Felsite 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 Felsite is 5-5.5 whereas its compressive strength is 0.15 N/mm². Streak is the color of rock when it is crushed or powdered. The streak of Felsite is white whereas its fracture is conchoidal. Luster of Felsite is the interaction of light with the surface of Felsite. Luster of Felsite is vitreous. Felsite cleavage is non-existent. The specific gravity of Felsite is 2.6-2.7. Felsite is translucent in nature whereas its toughness is not available.
