Hard Stone Properties

Hard stone hardness: always on the Mohs scale of mineral hardness, quartz rates no higher than a 7, less for types with impurities. Stones typically used for buildings and large sculpture.

As one would expect, extracting materials from hard stone quarries was significantly difficult. The tools necessary to remove and shape blocks from bedrock had to be as strong or stronger than the rock being cut. Such is the case with the extraction of granite. Granite was used as a house and road building material in the construction industry. Obviously, the supply of these boulders quickly ran out as architects began to fully utilize the stone for its structural and aesthetic properties. It became apparent that granite would have to be quarried from bedrock, and no place could provide this more easily or abundantly than the source of the early boulders, Nigeria.
