Generally speaking, the greater the density of agarwood, the more coagulated oil, and the better the quality. The ancients often classified agarwood grades according to whether it can sink: high-quality agarwood sinks when it enters the water, which is called "agarwood", followed by semi-floating and semi-sinking, which is called "overlapping fragrance", and once again it floats slightly on the water, which is called "yellow cooked fragrance". The highest quality of Aquilaria sinensis can not be tasted by traditional methods. The origin of Chimonanthus praecox is ingenious. It is a hollow fragrant tree (dense fragrant tree species) constructed by ants or wild bees. The formic acid, nectar or honey and bee pulp of wild bees are absorbed by the fragrant glands of fragrant trees and gradually formed by combining with a special fungus. This process continues to accumulate, causing the fragrant tree to break from the root or a branch, commonly known as "upside down" and be buried in the soil. Its parasitic fungi and resin are constantly absorbed and synthesized, and it takes a hundred or even a thousand years to be dug up by incense, so Qinnanxiang is extremely precious and rare.
The growth environment and parasitic bacteria of Phoebe bournei and Aquilaria sinensis are different, and their characteristics are also very different. The difference between them is that (1) Machilus is not as dense as Aquilaria sinensis, and the superior Aquilaria sinensis sinks in the water. On the other hand, Qi Nan is half floating and half sinking. ⑵ Most of the high-quality agarwood is hard, while Qinan is soft and sticky, and the fine powder cut by Qinan can be kneaded into a ball. (3) Through careful observation, it was found that the oil glands of Aquilaria sinensis were clumped, while the oil glands of Runnan were divided into woody glands with distinct layers. (4) Phoebe bournei has a strong fragrance without burning, and the fragrance is pure and elegant, so it cannot be artificially synthesized. If smoked, the aroma of Aquilaria sinensis will remain stable, and the head aroma, original aroma and tail aroma of Phoebe bournei will change obviously. Because Qin Anxiang is extremely rare and expensive, some people joked that it takes three generations to smell Qin Anxiang and eight generations to taste Qin Anxiang. In the agarwood world, there is an alternative way to taste Qinnanxiang. Take 3 ~ 5g of Qinnanxiang, and put it into the better rice shochu made by farmers. A year later, this wine will be used. The aroma is mellow and long, and famous wines such as Maotai and Wuliangye cannot be tasted at all. "Borrow a pot of agarwood wine and give me back my true colors", which is a very refreshing way to taste incense.
At present, there are many fake methods of agarwood on the market, such as perfuming, boiling, high-pressure oil spraying, and aggravating glue injection. The general identification in the industry is this: the appearance of agarwood is irregular at first glance, and the false appearance is regular, especially the epidermis is regular. The second touch: agarwood is moist in texture and smooth to the touch. After rolling, it is bright in patina, and it fades when attached to a fake hand, which makes it feel unsmooth. Three smells: Aquilaria sinensis burns easily, and the oil boils when it burns. The generated smoke is rich and pure, which can be directly drilled along the filiform path, and is not easy to burn, and the smoke has an odor. Due to different tree species and different catalysis of natural environment, the chemical changes of agarwood resin are different, and the ages are different, and the fragrance is also different. The fragrance of agarwood can't be described by accurate words: "cool and sweet", "mellow and lasting" and "elegant" are only understandable words. Only by smelling agarwood for a long time, seeing more products and communicating more can we distinguish the quality of agarwood.
In religious circles, Aquilaria sinensis has a high status and is recognized as a rare treasure by the five major religions in the world (Buddhism, Taoism, Christianity, monotheism and Islam). In China, agarwood has been regarded as the only aura tree that can communicate with the "Three Realms" since ancient times. It is considered to ward off evil spirits, be beneficial, promote luck and prolong life. It is a good thing for princes and nobles in past dynasties to enjoy and play with. In the medical field, Compendium of Materia Medica records the efficacy of "treating upper heat and lower cold, qi reversing asthma, large intestine deficiency, urinary stranguria and male cold". The medicinal value of Aquilaria Resinatum has been unanimously recognized in the field of traditional Chinese medicine, such as regulating the middle energizer, warming the kidney to absorb qi, treating toxic swelling of feng shui, eliminating pathogenic factors, nourishing the five internal organs, benefiting essence and strengthening yang, treating liver depression, reducing turbid qi, cooling the stomach, inducing resuscitation by inducing diuresis and so on. In daily life, agarwood has a unique calming and calming effect, which is worth mentioning. A year ago, the author put a piece of high-quality agarwood (Weibo) weighing more than 300 grams on the pillow. In summer and autumn, a gloomy and pleasant fragrance often escapes, which makes people feel safe and sleep well. How happy I am!

Current situation of agarwood collection
Compared with common collections such as calligraphy and painting, porcelain and coins, agarwood is still a niche collection, but with the passage of time and the popularization of related knowledge, it has gradually become a hot item in the collection market. As a collection with a long history, diverse functions and a certain mystery, the threshold of agarwood collection is not low. Mr. Shi Zhengdong, the first vice president of Jiangsu Collectors Association and president of Nanjing Xiangxue Research Association, said: "The supply of agarwood is very scarce. At present, most products on the market come from countries such as Vietnam and Indonesia. Although some agarwood is displayed and circulated in major antique markets across the country, there are few top-grade and top-grade products. To make matters worse, a large number of imitations and fakes are flooding the market. " Even so, in recent years, the transaction rate of agarwood auction market is still very high, and the transaction price is often several times or even dozens of times the valuation.
It is reported that Vietnam, which is rich in agarwood in the world, only produced 18kg of high-quality agarwood last year. The auction price of one gram of agarwood ranged from 1 1,000 yuan to 1 0,000 yuan, and the highest price reached more than11,000 dollars. "With the different geographical distribution of agarwood, different varieties and years, different growth environments, different appearances and wooden structures, the agarwood produced will emit hundreds of different magical fragrances. Among them, the Qinan species produced in Vietnam is the best of agarwood. Good Qinnan agarwood can feel the pungent and hemp in the fragrance when slicing. If it is chewed with sticky teeth, it is regarded as top grade, and the crumbs can be twisted into pills by scraping. Secondly, Aquilaria sinensis is a kind of agarwood produced in Hainan Island of China, which grows in the virgin forests of Jianfengling, Bawangling, Ying Ge Ridge, Limushan and Diaoluoshan Nature Reserve. Of course, the aroma of agarwood in other countries and regions also has its own merits. "
There are many samples of agarwood in Mr. Shi's collection, and he attaches great importance to the study of agarwood. Shi Zhengdong said that agarwood, as a revived collection, broke through a hundred years of silence and quietly sneaked into the domestic collection market, and the prospects are bound to be promising. Because in the past ten years, at least four or five provinces in China have been implementing the "Spark Plan", planting millions of agarwood saplings with a broad mind and vision, and backing up precious agarwood resources for future generations. At present, many high-end people at home and abroad have taken the lead in entering the field of agarwood collection. As we all know, an entrepreneur and collector posted online exhibited a dragon bed carved with 3 tons of agarwood in Putian, Fujian. It is reported that it was used by the royal family in the Qing Dynasty. 1993 The price bought from Shandong collectors is 20 million yuan, and the current offer is 500 million yuan.
I'm here? Is it sweet? Where to? You bought it. I never worry that it is fake. I didn't identify it, but it doesn't look fake. Praise is overwhelming.
