The mohs scale, named after Friedrich Mohs. Mohs' scale of mineral hardness is named after Friedrich Mohs, a mineralogist.Mohs scale is ordered by hardness, determined by which minerals can scratch other minerals.

For example, if you scratch a sample with a quartz point, then the sample has a hardness less than 7. If the tool does not scratch the sample, then it is harder than the tool. This is because materials of equal hardness scratch one another. For example, if you cannot scratch a sample with a quartz point, its hardness is greater than 7.

Quartz exists in two forms: (1) alpha-, or low, quartz, which is stable up to 573 °C (1,063 °F), and (2) beta-, or high, quartz, stable above 573 °C.The two are closely related, with only small movements of their constituent atoms during the alpha-beta transition. The structure of beta-quartz is hexagonal, with either a left- or right-handed symmetry group equally populated …

The interlocking crystalline structure of quartzite makes it a hard, tough, durable rock. It is so tough that it breaks through the quartz grains rather than breaking along the boundaries between them. This is a characteristic that separates true quartzite from sandstone. Quartzite is usually white to gray in color.
