The oak - a recognised symbol of eternity - was used within many centuries in building branch. Widespread in Europe, Asia and America, is breed traditional for Russia.

The oak grows practically across all Europe, both in the north, and in the south. In Finland an area of natural growth of an oak the Aland islands and coastal areas of Southern Finland. The oak also grows on caucasus and in some areas of Turkey. The oak easily reaches age more than 1000. Trees grow to 18-30 inches and in diameter of 120-180 inches.

A trunk of the oak growing in wood of a straight line and without knots to height of 15 inches. Differs the big variety since totals in total about 200 versions. Northern trees growing on bad soil, have the best wood, in comparison with wood of southern trees.

Oak colouring light yellow. Mature wood has colouring from brown to yellow with a beautiful structure on a cut. It strong, durable, is steady against external influences. In due course the oak darkens a little that gives a shade of noble olden time.

Oak wood dries up rather slowly, at the accelerated drying is inclined to formation of cracks. For giving to wood of an oak of higher decorative qualities, it often subject to drying. As oak drying understand its long-term keeping in water from what wood gets silky violet colouring.

Soaking increases hardness of wood, but its fragility thus raises. An oak bark and sawdust apply to impregnation of other breeds of wood that changes their natural colouring. For this purpose wooden preparations maintain in broth from a mix of a bark and a shaving of a trunk of an oak, sating with their strong substances. At a choice of a method of furnish of an oak product it is necessary to consider that this wood badly accepts spirit varnishes and polymers.

Polymers practically does not accept because of high porosity. The raised hardness of wood of an oak complicates in it of nails and screwing up of screws. Therefore is better to carry out preliminary drilling in order to avoid splitting of boards. Oak elements of a ladder well stick together among themselves.

Oak wood finds diverse application: in the form of a parquet, an interline interval for furnish of products, in the furniture industry, mechanical engineering, flanks for wine and beer.

To paint an oak it is not necessary, for this purpose it is necessary to use more accessible wood. At work with an oak it is necessary to consider that it is very sensitive to vegetable oil (sunflower, linen, natural drying oil, etc.) — on its surface from oil often there are stains. It is necessary to cover oak wood with transparent quick-drying varnishes.

With wide annual rings, a firm and heavy oak is better approaches for places from which strong wear resistance is required. Its wood approaches as for external, and internal application, for example for manufacturing of bridges, moorings. With thin annual rings, the easy and soft oak, is good for internal furnish, the furniture industry, a wooden sculpture, turning works.
