Let's talk about how to distinguish pure ebony.

The body is like carbon black, with different colors. When it turns black and shiny in water, it is coated with oil and burned with yellow ash, which is different from ordinary wood.

There are differences in weight, which can be heavy and floating, fragrant and odorless, and there are several. There are differences in tree species, but there is no smell.

Thousands of years of carbonization are gloomy, and years of sinking trees are good materials and full of spirituality.

Ebony (dark wood) belongs to the genus carbonized wood, so its trees are mostly black carbonized (generally, the longer the trees are, the higher the degree of carbonization), and the appearance of carbonization is similar to that of charcoal scorching, and carbonization cracks; 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").

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 cross section is smooth, the wood grain is fine, and the mirror surface can be bright when polished properly.

Ebony (dark wood) is more exotic than ordinary wood. Ordinary wood (except for Shui Mu) is burnt with white ash, while dark wood is burnt with 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.
