Granite, the hard natural igneous rock having visible crystalline texture is formed essentially of quartz and orthoclase or microcline. The principal constituents of granite are feldspar, quartz and Biotite. However the percentage composition of each varies and accordingly impart different color and texture to the final product. The percentage composition of feldspar varies between 65-90% , of quartz can extend from 10 to 60% and that of biotite lies between 10 to 15%.
