The difference between granite and marble

1. The difference in material hardness

Marble can be scratched with a knife or nail, but granite is not easily marked by these. Because the hardness of granite is between 6 and 7, and marble is only 3-5, marble is softer and granite is harder.

2. The difference in stability

The stability of marble is cross, and the stability of granite is good. Therefore, marble is easily deteriorated under the action of sunlight, rain, wind, and ultraviolet rays, while granite is more difficult to change.

3. Differences in chemical reactions

Marble is more afraid of chemicals, while granite is relatively stable. Marble is particularly afraid of acid and alkali chemicals, and its resistance to acids and alkalis is particularly poor. This feature determines that it is better to use granite instead of marble for kitchen countertops.

4. The difference between defects

Marble has various stone defects, such as cracks, crystal spots, holes, and chromatic aberration, while granite is relatively good. The defect of marble determines that marble is suitable for interior decoration, and it is less used for outdoor and high-altitude decoration. Otherwise, once the marble falls due to cracks, the consequences will be unimaginable.

5. The difference in wear resistance

Marble has poor abrasion resistance, while granite is just the opposite. Therefore, marble is rarely used at the entrance of buildings and public places, otherwise the marble surface is very easy to wear and tear and lose its brilliance.

6. The difference in anti-deformation ability

Marble is volatile, and granite has strong resistance to deformation.

7. The difference between weathering phenomena

Marble is prone to fading, fading, weathering and other phenomena. This heat determines that it is better not to use marble as a decoration for common outdoor light and rainwater. Otherwise, after a period of wind and rain, it will lose its previous beauty.

8. Strength difference

The strength of marble is lower, and the strength of granite is higher. This feature determines that it is better to use granite instead of marble for floor decoration, especially in airports, large shopping malls, subway stations, hotels, and hotel entrances where the flow of people is particularly high.
