Granite stone.

Granite is a sub-surface rock appeared from fire-liquid melt in the depth of surface crust. The appearing of the granites is not connected with the definite geological epoch; they had been forming during the whole period of Earth history. The word origin is from Latin granum (kernel) and is connected with its granula structure.

The density of granite is 2.7. Instead of biotite or together with it pyroxene or hornblende. The German miners' proverb about the components of granite sounds like this: “I will never forget feldspar, quartz, mica”. It treats the composition of granite in a lite way.

Usually granite is of light coloures because of light coloured components. Light blue, yellow, red, green, grey, it always gives an impression of a light coloured item. Granites have such color casts thanks to feldspar. In origin quartz usually seems to be grey, though in mono minerals or crystals it is colorless. It seems grey because of dark background. Dark coloured mica (biotite) is spread regularly or partitionly in granite. The rest components of granite are seen only in some kinds of granite.

Granite is the most favourite building stone. A big quantity of quartz makes it highly resistant to wear, feldspar allows to process it very easily. Grey granite is widely used as border and boundary stone or as crushed rock in angle fragments.

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.

Balusters, vases, granite tiles, balls, standard tombstones are produced at many stone-working plants. And complicated individual orders of high art level are born in the workshops of talented sculptors who have perfectly mastered the granite processing and inquired its nature.
