How to distinguish a piece of wood - is it a good quality log?
How to determine whether a piece of wood is a good quality log?
the first,
The hardness and specific gravity of the log wood. Wood is naturally harder and better. If it has both high hardness and high flexibility, it is better, such as huanghuali, teak, yam, oak, walnut, etc. The best of them is huanghuali, wood. The proportion, which is often said to be heavy on the hand, is mostly good wood; on the contrary, if it is lightly held in the hand, the material is no better. When the air dry density is greater than or equal to 1, the wood is called a submerged material. In the submerged material, it is difficult to find wood with poor material quality. Distinguish from the density of wood: From the cut surface, the density of the wood is large, and the density is hard and slippery. If the rough surface indicates that the wood density is small and the weight is light, it can be seen by sliding the iron on the section.second,
High-quality logs must have a certain degree of oiliness. Of course, the oiliness of wood is heavier and better. This is the handle of good log processing. The long-term play will form a pulp. The oiliness of wood is an important indicator of the superiority of the material. The more oily, the more oily, It often means that the aroma is more intense and lasting, and the stronger the insect resistance and corrosion resistance of wood. Hainan huanghuali is divided into avocado and avocado in terms of oiliness, while the value of avocado is more than double that of avocado.
third,
Wood grain, wood color, good logs, with delicate colors and wood grain, the icing on the cake, the value is naturally much higher, the high-grade wood must have beautiful wood grain, yellow pear, rosewood, old mahogany, red shadow wood, gold Silkwood roots and the like are typical. It is distinguished from the color: from the perspective of the whole tree and the cut surface, the color is bright, but the wood that is a little longer is not bright, but the color is white, yellow, red, etc. In short, it cannot be black unless it is special wood, black is generally Long-term moisture and mildew wood corrosion.
fourth,
The characteristics of high-quality logs are the natural special wood aroma. Such as Indian Laoshan sandalwood, huanghuali, rosewood, and nanmu wood have such characteristics.
fifth,
Distinguish from the sound of wood: the sound of knocking wood is crisp and the wood is good. If the sound is dull, the wood is deteriorated.
Finally, summarize:
Identify high-quality logs from five points: wood hardness, density, color pattern, aroma, and sound. The wood is born from the heart, the wood is born, and the Chinese love the wood. It is like loving the homeland and the home, and there is always a feeling of hardship.
