the FURNISH GENERAL CHARACTERISTIC. Structure drawing

Structure Drawing changes depending on a processing direction, i.e. From a cutting plane - radial, tangential, radially-face, tangentsialno-face. Usually use first two directions of processing - radial (in parallel serdtsevinnym to beams) and tangential (it is perpendicular serdtsevinnym to beams). At the majority of breeds (an oak, an ash-tree, mahogany, a nut, a black rosewood, etc.) both these directions give beautiful drawing, at some is of interest only one of the specified directions of processing. In structure revealing the considerable role is rendered by colour, especially contrast in colouring of early and late wood.

Oak Wood is interesting both on tangential and on radial cuts as in creation of drawing of a structure participate as serdtsevinnye beams, and year rings.

All variety of variants and structure compositions can be shown to the following characteristic kinds most often applied in the industry.

1. Wood without the expressed drawing with ravnokrashennoj a surface with slabozametnym a direction of fibres. Wood of a birch, a linden, a pear has such character of a structure at reception of facing materials on the basis of these breeds as planing, and lushcheniem.

2. Shaped drawing of a structure with the small homogeneous strokes which are turning out as a result of rupture serdtsevinnyh of beams (wood of a beech and a number of other breeds).

3. Moire drawing, obrazuemyj on a radial cut game of the opened vessels located in the form of breaking strips. Such structure is characteristic for mahogany, a wavy maple and a birch.

4. Striped drawing is formed on radial cuts of tree species with strongly pronounced contrast in colouring of early and late wood. The structure is characterised by alternation of narrow and wide dark and light strips. Drawing is characteristic for coniferous breeds, mahogany, a nut, a black rosewood and other breeds.

5. Wavy drawing is formed on a radial cut of wood with the abnormal form of a trunk (svilevataja wood of a birch, a maple, mahogany) or by figured wavy processing of wood (lushchenie) the special cutting tool (a birch, an ash-tree, etc.).

6. U-shaped drawing of a structure is characteristic for a tangential cut. Drawing is created by the year layers getting to a cut in the form of parabolic (bow-shaped) lines, often wrong form. Serdtsevinnye beams are not appreciable almost and do not render influence on character of drawing, drawing at coniferous breeds, a nut, an ash-tree and an oak is most brightly shown.

7. Curvilinear drawing of a structure is formed on a tangential cut of some deciduous breeds of wood (a nut, karagach, etc.) under abnormal conditions of growth of a tree. Versions of this drawing are rakovinnyj and naplyvnyj, formed at processing komlevoj parts kapov or flows of some deciduous breeds (nut). Drawing thanks to chaotically intertwining lines and stains possesses valuable decorative qualities.

8. Listoobraznyj drawing is characterised by the ellipse lines of the wrong form closed on a tangential cut.

9. Knotty drawing (in the form of separate central stains and knots and of some concentric circles of phaeochrous wood) is formed at processing of the wood containing a significant amount of knots (a pine, a fur-tree, an acacia). High decorative qualities are inherent in a version of this drawing at wood ostrolistnogo a maple (' the bird's eye '), obrazuemogo small ' eyes ' with a diameter from 2 to 5 mm, representing turn of fibres about a place of possible formation of a knot, and also wood of the Karelian birch which characteristic drawing is created by chaotically located dark brown strokes formed by cages serdtsevinnyh of beams.
