Colour of wood from kremovo-white to pale yellow colour. Wood abachi soft, but strong and formoustoichivaya. A structure small and equal. Fibres it is frequent putano - svilevatye, on radial raspilah form poorly appreciable strips.
Hardness dreveseny
Hardness - ability of wood to resist to penetration of firmer bodies. The Structure (English - texture) - natural drawing, visible at a trunk cut, the visual characteristic of wood defined by its anatomic structure, width and the form of year rings.
The invoice - a visible structure of a surface of a material. There are invoices relief and smooth. In turn relief invoices share on corrugated and imprinted, at carpet products - nap.
Fold - rectangular sample on a board or board edge. The square fold with the party equal to half of a thickness of a board, is called as a quarter.
Inflated dreveseny
wood Swelling - ability to increase in the sizes at saturation by a moisture. Early wood (English - early wood) - a part of a year ring which is formed in an early stage of the period of growth. Less dense and more light, than late wood. Svilevatost' - a wavy, chaotic arrangement of fibres of wood.
Core (English - pith) - the narrow central part of a trunk consisting of a friable (soft) fabric, characterised brown or more light, than at surrounding wood, colour.
Serdcevinnyi a beam (English - ray) - lentopodobnoe formation from the cages, directed radially in relation to growth layers.
oxidation Degree
oxidation Degree - an indicator of change of colour of wood under the influence of light. At small degree of oxidation wood does not darken, at average - wood under the influence of light darkens slightly, and at high - dimness will be considerable.
Hardness of wood
For each breed of wood its operational indicators are resulted, namely:
• Hardness - an indicator of service life of the top (useful) layer of wood. At low hardness the useful layer of wood wears out faster, at average - more slowly, at high - very slowly.
• Stability and degree usadki - very important indicators which are necessary for knowing for this purpose:
