2020-10-29 Example: You select one of the minerals from Mohs Scale that looks like the one pictured here and find that it can be scratched by the knife (H=5.5) but not by the penny (H=3). Therefore, you are able to conclude that the specimen has a relative hardness between 3.0 and 5.5. The minerals from Mohs Scale that fall into that relative hardness range are calcite (H=3), fluorite (H=4) and apatite ...
