The hardness of quartzite is mainly determined by the physical properties of its main mineral component, quartz. In general, the hardness of quartzite is quite high, making it a durable rock type.
The hardness of quartzite is mostly between 6 and 7 on the Mohs scale, which allows it to resist a certain degree of wear and scratches. Specifically, the Mohs hardness of quartz reaches level 7, making it one of the hardest minerals in nature. Therefore, quartzite composed of a large amount of quartz also has relatively high hardness. For instance, our Lyon Grey Quartzite is very hard.
However, it should be noted that the hardness of quartzite may vary depending on the content and distribution of other minerals in the rock. For example, if quartzite contains more feldspar or other minerals with lower hardness, its overall hardness may decrease accordingly.
In addition, the hardness of quartzite is also influenced by its formation process and geological conditions. During the process of metamorphism, quartz sandstone or siliceous rock may undergo high temperature and pressure, and the quartz particles in it may crystallize and grow into larger crystals, thereby increasing the hardness of the rock.

Overall, quartzite composed of a large amount of quartz and subjected to high temperature and pressure typically has higher hardness. However, the specific hardness value may vary due to factors such as the mineral composition, formation process, and geological conditions of the rock. If accurate hardness data is required, it is recommended to conduct professional rock testing and analysis.
