Why is quartz so hard The hardness of quartz is derived from its atomic mineral structure. The strength of the framework silicates is that oxygen and silicon atom are all connected in a network of strong bonds. This network structure is why quartz breaks with no clear planes of cleavage, called conchoidal fracture, like broken glass.

Because it is so hard and dense, quartzite has not been quarried as extensively as other softer dimension stone (such as limestone, sandstone and granite).
Environmental characteristics include the nature and distribution of inorganic contaminants, such as metals and metalloids like arsenic, iron, and lead, in clay-bearing rocks. These environmental factors have the potential to affect the use of clays in natural and industrial applications. --NORA K. FOLEY.
