ABSTRACT
Moh’s Scale of Relative Hardness* Resistance to scratching and durability to foot traffi c are largely dependent upon the hardness of the minerals that make up the stone. The hardness of a mineral is often defi ned by use of Moh’s Scale of Relative Hardness, developed in 1822 by the Austrian Mineralogist Friedrich Moh. This scale lists 10 minerals in ascending order of scratch resistance, with 1 as the softest and 10 as the hardest:
Characteristics of common stone
Granite
Colour There are more than a hundred distinct colours with varying patterns.
