Marble Vs Granite Hardness

Granite is comparatively harder and stronger than marble.

Marble vs granite hardness.

As a result marble is less porous and slightly stronger than limestone but still less durable than granite. Marble will also scratch more easily since it scores a four on mohs scale of hardness versus granite s rating of seven. When choosing countertops for your kitchen or bathroom granite and marble surfaces are popular choices. It has been in use extensively since the ancient times for both indoor and outdoor applications.

Granite has a mohs hardness rating of seven. The main difference is that granite and marble are made of different minerals that perform differently in regards to chemical resistance and hardness. Marble will etch when exposed to acids and bases. 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. An example of the hardness of a granite countertop can be seen in the fact that a knife blade will not scratch the surface. Marble is limestone that has been compacted and heated over millions of years. They are natural stones unlike say engineered quartz silestone so both marble and granite surfaces are susceptible to chipping and st.

Some people assume that. Granite is mainly composed of quarts and feldspars it is coarse grained and usually in light colors. Both materials are heat resistant though caution should be used with hot pots and pans in the kitchen or hot hair tools in the bathroom.
