Mohs hardness: 3 Chemical Formula: Cu Color: Copperred to brown. Tarnishes green, sometimes also blue, brown, red, or black. Streak : Copper Red, shiny streak crystal system: Isometric Where is it found: Most common in volcanic basalt rocks, often near the level of contact with sedimentary rock layer.
The hardness of material is measured by determining which material can scratch or be scratched by others, if they can scratch one another then they are the same hardness. For example if a given material is scratched by Corundum but not by Diamond, its hardness on the Mohs scale is The Mohs scale is truly a comparative scale.
