Is Marble Harder Than Limestone

3 limestone is a sedimentary rock while marble is a metamorphic rock.

Is marble harder than limestone.

Even though it is harder than limestone it is not as hard as granite. Marble is a very hard stone. Limestone is a soft easily workable rock that is comprised of at least 50 calcite aragonite and or dolomite. Marble basically classifies into four groups which include.

Even though it is harder than limestone it is not as hard as granite. Marble is relatively hard but not as hard as granite. Groups a b c and d. Both stones also share a vulnerability to acidic materials.

Slightly softer than granite and gemstone quartzite quartz and onyx each rank at a 7 on the mohs scale. Limestone imported from other countries is often light or even dark red brown or black. While marble is slightly harder and denser than limestone both rate very low on the mohs scale a rating used to measure the hardness of stones. Wipe with a clean damp cloth if dirty.

Marble is slightly denser and harder than limestone but both stones are relatively soft which makes them easy to work with. Marble is created when the sedimentary stone limestone or travertine is exposed to heat and pressure over a long period of time. Marble is a very hard stone. Limestone generally ranks at around a 3 on the scale while marble falls between 3 and 4.

The recrystallization allows the marble to take a nice and beautiful polish finish during fabrication. Minerals do have defined hardnesses though. 5 limestone is more porous than marble while marble is harder than limestone. While not as hard as granite and gemstone these surfaces are still very hard and are unlikely to scratch.

The stone undergoes a metamorphosis it recrystallizes and becomes denser and harder. These merely indicate fabrication ability which is based on the materialís level of hardness. Select limestone with mineral dolomite present as this type of limestone can be polished and is harder than other types of limestone. Masonry repair and restoration from del prete masonry.
