The 10 standard minerals of the Mohs hardness scale from softest to hardest are talc, gypsum, calcite, fluorite, apatite, orthoclase, quartz, topaz, corundum and diamond. The Mohs hardness scale is an excellent tool for identifying minerals. It is a comparative scale. Other methods are .
Granite is a felsic rock, meaning that it has a high silicon content; it is mostly made out of quartz, mica and feldspar. Basalt, as a mafic rock, contains more calcium oxide, manganese oxide and iron compounds than granite. Its high iron content gives it magnetic properties, and it may show signs of rust when exposed to air.
