Black Galaxy Granite is one of the most durable stones, which has been incorporated well in infrastructures of the present times. The word "Granite" originates from the Latin word 'granum', referring to the coarse-grained structure of this crystalline rock. It is composed of quartz, feldspars and micas, as well as traces of a variety of other minerals, which contribute to the color and texture of natural granite stone. These granite stones are available in pink, dark gray or even black, depending on their chemistry and mineralogy. A broad range of elegant patterns and colors makes granite the most versatile of all stones. The crystal size of the natural granite stone is somewhat determined by the rate at which the granite cools: the slower the cooling process, the larger the crystals grow. Occasionally some individual crystals (phenocrysts) are larger than the ground mass in which the texture is known as porphyritic. Indian Granite Stone is a common and widely occurring type of intrusive, felsic, igneous rock with great strength and value. The density of granite is 2.75g/cm3 (avg) and its viscosity at standard temperature & pressure is ~4.5 • 1019 Pa·s. Natural Granite stone is typically the hardest of the dimensional stones and can withstand the vagaries of nature, effectively. The natural properties of this stone makes it the real "maintenance-free" stone.
