This is an abyssal rock, appeared from fiery-liquid melt in the bowels of the earth's crust. The appearance of granites was not attached to any definite geological epoch; they were generated during all the history of the Earth. The name of the rock comes from the Latin "granum" – "a grain", and is connected with its granular structure.
The density of granites is 2,7. Instead of biotite, or together with it, pyroxene, or hornblende, may be found there. "I will never forget feldspar, quartz, mica" – says the proverb that is popular among the German miners' and reflects the structure of granite in a simple way.
Due to a high content of light components, granite is usually coloured in light tones. Either light blue, light yellow, light red, light green or light grey granite of a normal content always produces general impression of a light-coloured rock. Granites owe their colour tints to feldspar. Quartz as a rock usually seems of grey colour, although it is often colourless in monogenic species and crystals. Darkness of the background, peeping out of glass-transparent grains of quartz, gives granite grey colour. Dark-coloured mica (biotite) is either distributed in granite evenly, or forms dense nest-shaped accumulations. Other (accessory) components make some importance only in certain kinds of granite.
Granites are widely used in architecture all over the world. Thanks to its multicoloured structure it is used in casing of buildings fronts, floor covering, making fireplaces, etc.
Thanks to new achievements in granite processing and modern diamond instruments the terms of producing and the quality of products have changed to rather better.
Granite is a favourite building rock. It has high resistance to deterioration due to presence of big amount of quartz, and is very workable on certain surfaces due to high content of feldspar. Grey sorts of granite are used as paving blocks of border (kerbstone) and boundary rocks, or as crushed rock of various fractures (angle fragments).
Granites are widely used in architecture of many cities of the world. Façade lining, floor covering, construction of fire-places and other goods is possible due to a wide range and variety of this rock
Due to the new achievements in the field of granite processing and due to up-to-date diamond tools the quality of manufactured products has become better, and terms of their manufacturing have been reduced.
Balusters, vases, granite tiles, balls, standard gravestones, and other sophisticated products are produced at many rock-processing factories, and sophisticated individual orders of a high art level as one-of-a-kind items are born in workshops of talented sculptors, who had become proficient in rock processing and had learned its essence.
