Marble Vs Granite Hardness

Marble is limestone that has been compacted and heated over millions of years.
Marble vs granite hardness. It has been in use extensively since the ancient times for both indoor and outdoor applications. Marble will also scratch more easily since it scores a four on mohs scale of hardness versus granite s rating of seven. Granite has a mohs hardness rating of seven. Granite is harder than marble so it is more resistant to chips and scratches.
Some people assume that. The main difference is that granite and marble are made of different minerals that perform differently in regards to chemical resistance and hardness. As a result marble is less porous and slightly stronger than limestone but still less durable than granite. Marble will etch when exposed to acids and bases.
An example of the hardness of a granite countertop can be seen in the fact that a knife blade will not scratch the surface. 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. 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. Granite is comparatively harder and stronger than marble.
