Second, the ebony profile:

1. Ebony (dark wood) belongs to carbonized wood, so its tree body is mostly black carbonized (generally, the longer the tree age, the higher the carbonization degree), and the carbonized appearance is similar to scorching and carbonization cracking; Painting on white paper with its carbonized wood will not produce black scratches of ordinary charcoal; Some experienced masters generally comprehensively evaluate the approximate age of formation and possible tree species from the aspects of appearance carbonization degree, section condition after grinding, hand feeling, etc., and judge whether it belongs to a gloomy level; Generally, trees that completely enter the gray level need to undergo at least thousands of years of infiltration (oxidative carbonization); Other immature (lack of carbonation) logs are sometimes just submerged logs (some submerged logs were formed after being submerged under water for many years, and do not have some conditions formed under "hypoxia and high pressure").

2. Ebony (dark wood) is hard (iron dark wood is the hardest and Toona sinensis dark wood is soft; Whether it can sink into the water after returning to the sun (naturally drying in the shade) after forming a shady tree mainly depends on the different tree species it forms, which can sink and float; In particular, some small pieces of finished products generally float on the water, and it is impossible to identify whether they are dark wood by whether they can sink into the water. Most of them are brown-black, black-red, gold and tan. Its section is smooth and the wood grain is fine, which can be polished to mirror brightness.

Ebony (dark wood) is more peculiar than ordinary wood. Ordinary wood (dark wood, except in special circumstances) burns white ash, and dark wood burns yellow ash. It darkens when exposed to water and returns to its original color after drying. A little vegetable oil will shine black and won't fade. When most of the black wood was unearthed, the core of the tree had rotted, leaving only the middle layer of the head and trunk; The severely carbonized surface can not be used as a general material, so it is generally necessary to shave off its outer layer and leave the wood core for later use.
