Limestone Marble And Granite Hardness

As a result marble is less porous and slightly stronger than limestone but still less durable than granite.

Limestone marble and granite hardness.

Marble and limestone lie at the opposite end of the hardness scale from granite. Depending on the properties like hardness toughness specific heat capacity porosity etc rocks are resistant to heat wear impact etc granite is heat resistant wear resistant whereas limestone is pressure resistant. Because granite is between a 6 and 7 on the mohs scale it would be able to scratch other types of stone that have lower ratings such as marble. Depending on the limestone and the mineral combination within the marble most marble rates from three to five on the mohs hardness scale.

When it comes to classifying a natural stone granite before making a purchase stone buyers like to focus on the relative granite hardness to know how hard a stone is in comparison with other natural stone products like marble sandstone slate limestone and quartzite. Using mohs scale of hardness for minerals you can with a bit of detective work find out the hardness of granite limestone and marble but i think that we can do a bit of reasoning and figure. The specific heat capacity of granite is 0 79 kj kg k and that of limestone is 0 91 kj kg k. Mohs hardness in 1 2 f 2 6 are soft stone such as limestone and dolomite etc.

Corundum absolute hardness 400 diamond absolute hardness 1500 soapstone 1. The indian stone industry has evolved into the production and manufacturing of blocks flooring slabs structural slabs monuments tomb stones sculptures cobbles pebbles and landscape garden stones. Marble is limestone that has been compacted and heated over millions of years. The hardness of stone is measured by mohs hardness as a unit of calculation mohs hardness in the 6 7 f 14 20 are hard stone such as quartzite and granite.

Mohs hardness between 3 to 5 f 8 14 belong to the medium hard stone such as marble. 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. An example of the hardness of a granite countertop can be seen in the fact that a knife blade will not scratch the surface. Reviewing this guide can help you keep in mind what the mohs scale of hardness is and how it can be applied to evaluate different countertop options.

Limestone generally ranks at around a 3 on the scale while marble falls between 3 and 4.
