Mineral Identification Key Hardness
Since the "scratch test" is very important to the identification of minerals every effort should be made to get a positive result – be sure that the correct hardness is determined With some samples, it may take several tries before one can safely conclude the sample’s hardnessIdentifying minerals by physical properties The most common minerals in Earth's crust can often be identified in the field using basic physical properties such as color, shape, and hardness The context of a mineral is important, too – some minerals can form under the same conditions, so you are likely to find them in the same rock, while others form under very different conditions and will Properties of Minerals Earth Science VisionlearningA great example of the importance of crystal structure is the difference between two minerals; graphite and diamond Graphite is the soft, dark colored material that is found in pencil lead, while diamonds are very hard, often transparent and colorless, and very expensive gemstonesWhy Is Crystal Structure Important?

Alkalinity and Hardness
Water moves through rocks (and picks up minerals as it does so) on its way to rivers and lakes When limestone and dolomite dissolve in water, one half of the molecule is calcium or magnesium (the "hardness") and the other half is the carbonate (the "alkalinity")Over 90% of the Earth's crust is made up of silicates The rest of the minerals are lumped into a group called nonsilicates Some important nonsilicate minerals include: Carbonates Carbonates contain carbonate (CO 3) combined with some other element Calcite is a mineral Earth Science for Kids: Minerals DuckstersMinerals are formed naturally by geological processes A mineral is a homogeneous solid that can be made of single native element or more usually a compound Minerals make up Earth's rocks and sands, and are an important component of soils 5 characteristics required of all minerals Be naturallyoccurring (manmade substances such as steel are Minerals Geology (US National Park Service)

BASIN: General Information on Hardness
Hardness is measure of polyvalent cations (ions with a charge greater than +1) in water Hardness generally represents the concentration of calcium (Ca 2+) and magnesium (Mg 2+) ions, because these are the most common polyvalent cationsOther ions, such as iron (Fe 2+) and manganese (Mn 2+), may also contribute to the hardness of water, but are generally present in much lower concentrationsThe Mohs scale of mineral hardness is a qualitative ordinal scale that characterizes the scratch resistance of different minerals through the ability of a harder material to scratch a softer material It was created by the German geologist and mineralogist Friedrich Mohs in 1812 and is one of several material science definitions of hardness Mohs Hardness Scale Geology PageMohs' scale of mineral hardness is named after Friedrich Mohs, a mineralogistMohs scale is ordered by hardness, determined by which minerals can scratch other minerals Rocks are made up of one or more minerals According to the scale, Talc is the softest: it can be scratched by all other materials Gypsum is harder: it can scratch talc but not calcite, which is even harderMohs scale of mineral hardness Simple English Wikipedia
