Web26 jan. 2024 · Then, look at the Mohs hardness scale to identify minerals that have the same hardness level. For example, if the copper penny (3) didn't scratch the mineral but a steel nail (5.5) did, you know that the hardness is between these. You can safely estimate the hardness of your mineral to be 4, which might be fluorite. Web13 okt. 2024 · Hardness: Three to four on Mohs scale (i.e., harder than fingernail but softer than knife blade). Bulk Density: This measure of heaviness is variable between limits, depending on the relative amounts of calcite and dolomite minerals in the rock and on the porosity of the rock. Representative bulk density values for intact rock are tabulated below.
