Marble stone hardness.

Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite marble is typically not foliated although there are exceptions in geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is commonly used for sculpture and as a building material. This allows attractive pieces of marble to be cut polished and used as floor tiles architectural panels facing stone window sills. 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.

In addition whether you choose a harder stone like granite or gemstone or a softer stone like limestone or soapstone you can be prepared to be as cautious as you need to around the surface. An example of the hardness of a granite countertop can be seen in the fact that a knife blade will not scratch the surface. Each natural stone has a strength rating often referred to as its mohs hardness. The granite hardness helps buyers make a balanced decision.

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. After being sanded with progressively finer abrasives marble can be polished to a high luster. The mohs scale of mineral hardness was developed to identify the strength and hardness of any natural mineral.
