The empirical standard for judging the quality of wood is essentially the common sense of wood that has been tempered and tempered. Next, Luxury Hotel Furniture Factory introduces the common sense of judging the quality of wood:

1. The general grade of timber: timber is roughly classified according to its use, from high to low, it is divided into high-grade craft wood, high-grade furniture wood, high-quality furniture wood, ordinary medium-sized furniture wood, middle and low-grade furniture wood, and firewood. In different areas, two adjacent grades of wood can be crossed. For example, some woods that are regarded as firewood in the southern forest areas will be regarded as mid-range furniture woods in the northern areas; mahogany, which is regarded as the top quality wood in Europe, can only be regarded as medium furniture woods and decorative materials in China.
 
2. The presence or absence of core wood is an important watershed between the pros and cons of wood: Generally speaking, tree species that do not grow core wood are no better, at best, they can only be used as middle and low-grade furniture wood. For example, fir, cypress, elm, most pine, and many species in the Lauraceae Phoebe genus, do not grow core wood. Although the wood that does not have long heartwood has very good materials, most of the wood that does not have long core wood can only be used as raw materials for firewood or synthetic wood; and all high-grade woods and high-quality woods are made of long cores. The original material of the tree comes from, and the genuine product only refers to its core material, and does not include the sapwood of the tree species, nor does it include the tender material of the tree species that has not yet formed the core material.
 
3. Wood hardness and specific gravity: naturally the harder the wood, the better. Of course, if the wood has both high hardness and high flexibility, it would be better, such as teak, phoebe, oak, walnut, etc., among which the best quality is yellow rosewood. The technical term for the specific gravity of wood is called air-dry density, which refers to the number of grams per cubic centimeter (g/cm3) when the moisture content of the wood is about 12%. This index is of course the higher the better, that is, we often say that most of the wood that feels heavy in the hand is good wood; on the contrary, if it is light and light in the hand, the material is no better. When the air-dry density is greater than or equal to 1, the wood is called submerged material. Among submerged materials, it is difficult to find wood of poor quality.
