Materials what we go through in our daily life are probably more deep-seated in our culture than most of us realize. From housing to recreation, virtually every segment of our life is influenced to one degree or the other by materials. Historically, the advancements and developments of our society are connected intimately to the member’s ability to manipulate and produce materials to fill their needs. As we know that early civilizations generally been designated by the level of advancement and development of materials; like stone age then bronze age, iron age and so on. With time passes people discovered the various techniques for producing materials that had properties superior to those of the previous ones. The development of many technologies that make our existence so comfortable today has been closely connected and associated with the accessibility of suitable materials such as granite.
There it comes; known as the oldest igneous rock known on Earth. Derived from the latin word “Granum” which means grain because of its granular structure. It is the most well known igneous rock characterized by its coarse, grainy appearance. Its granular appearance comes from the formation of small crystals that can be seen within the rock from the microscopic view. Due to presence of high level of feldspar content it seems typically light in colour. It is an intrusive igneous rock meaning it is formed from the cooling of magma; which is quite deep in the earth’s surface that eventually results solidification and crystallization. The temperature at which the cooling occurs defines the minerals in it and hence the type of rock is formed. There is a considerable amount of silica present which demands low temperature. It has high silica content and mostly made up of feldspar and quartz. Now it’s important to note that the percentage composition in Granite varies greatly and accordingly impart different colour and texture to the final product. It is generally found in the continental crush covers majorly North America and Canadian Shield. The countries where granite is found in abundance are Canada, India, and china, Brazil, Portugal, Spain, Finland and South Africa. So from the mineralogical point of view; its essential minerals are quartz and feldspar. The accessory minerals are biotite, amphibole, and muscovite. Chemically, SiO2 is more than 65%, remaining oxides vary. It is thermally stable, shows no change with the atmospheric changing temperature and impervious to air borne chemicals. One another catch of Granite is that It is highly resistance to chemical erosion which makes it useful for making tanks to store highly caustic material.
It is frequently selected and thought of as a prestigious material due to its beauty when polished. It is hard enough to resist abrasion, strong enough to hold significant weight. These characteristics make this a recommendable and useful dimension stone. The stones are non-porous, which means the surface is scratchproof which makes it difficult for the surface to retain dust and dirt eventually easy to clean. The surface is extremely solid; it comes second in line after diamond for strength and hardness on the Mohr’s hardness testing. That’s why; it last more than any other kitchen remodelling material.
