Marble. Marble comes from limestone that has been subjected to intense warmth and stress over the years. Marble is a great deal more difficult, as it rates around 3-5 on the Mohs scale of hardness. Marble usually has a glossy surface with distinctive veining and patterning. Durable marble works well for flooring, countertops, tiles, and ...

Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is …
