The result is this ordinal scale of minerals by hardness, with 1 being the softest and 10 being the hardest. To give you an idea of how durable the stones in our staircases and fireplaces are, we have added them to our revised version of the hardness scale: The Mohs Scale of Mineral Hardness 1. Talc 2. Gypsum 3. Calcite 3.5 Limestone Although relatively soft, with a Mohs hardness of 2 to 4, dense limestone can have a crushing strength of up to 180 MPa. For comparison, concrete typically has a crushing strength of about 40 MPa. Although limestones show little variability in mineral composition, they show great diversity in texture
. The Hardness (H) of Calcite on Mohos' Scale of Hardness is only 3. It is only a little bit harder than Gypsum (H=2) and Talc (H=1). This means that Limestone is NOT a Hard Rock Chemical Composition: Calcite. Texture - Clastic or Non-Clastic. Grain size - Variable, can consist of clasts of all sizes. Hardness - Generally hard. Clasts - if clastic / bioclastic then grains and / or broken or whole shell fragments visible; if non-clastic / chemical then crystalline and no clasts visible Limestone Mohs hardness - (3-4) Interestingly, the hardness of all black, green, red, yellow, brown, pink, and white granite are more or less the same: 6-7. You can confirm the granite hardness with quality reports from granite supplier and exporter of your choice
