Identification techniques of agarwood:
Generally, the agarwood is easy to recognize, but it is difficult to define from the picture. The picture I sent you is the water sink. Agarwood's first-grade product can not be used as a raw material for the bracelet, because it is soft and easy to deform and damage, so it is not suitable as a bracelet. As I said before, the agarwood is divided into dead and heavy, and the aloes in the living and sinking can only emit fragrance when it is ignited. It is the best raw material for the high-grade fragrance products of religion and the most precious raw material.
The first type of inverted frame is generally considered to be the best agarwood, and is generally distributed in the primary or secondary classification. It can be said that the inverted frame has been screened out by superiority and inferiority, and the rest are the best parts. Therefore, the general agarwood bracelet that is inverted is not one level or two. I rarely see this type of bracelet.
The second type of "water sink", this kind of agarwood is generally produced from the marsh, distributed in the first to second grades, and the level is very broad.
The following is the classification and identification of the water-sinking bracelet.
The second-grade agarwood bracelet is called A goods on the market. The following is the identification of the A-sink of the water sink.
(1) Look: The surface pores of agarwood are exquisitely A goods, and those with large pores are B goods (three-level products). It is different from the first to third grades of black soil. Generally, only the best first grade product is black. The water sinking A product is generally dark brown, and also has dark blue color. If someone gives you A string of black-colored agarwood bracelets is said to be a second-class product of water sinking. Generally speaking, only those who are shoddy or not know themselves.
(2) Smell: This is the most important means of identification. Generally, the smell of agarwood begins to smell like a familiar medicinal taste, but when you look carefully, you can't remember what it tastes. The most important difference between water and soil sinking is that the soil sinks thick and violent, and the water sink is mild and mellow. The smell of agarwood is mainly judged by the means of "drilling", what is the drill? The taste of agarwood is drilled, drilled into your nostrils, and the taste of really agarwood should be that the taste is along the wire. The path is drilled into your nose. The third way to judge is to "put". If you have the conditions, you can put it next to the pillow. During your relaxed sleep at night, you can smell the taste for a while, intermittent. If it is a fake, the taste is not a burst.
(3) Touch: The second product of the water sinking looks like a layer of oil (A-goods are also available, but not obvious), but the feeling of the hand is not oily when it is not dirty. If it is a fake, this oil will leave a dirty mark on your hand.
(4) Submerged water: You can take down a bead and put it in a cup of pure water. You can see that the incense can't wait to sink to the bottom of the cup, but this method is not scientific and can only be regarded as a condition for judgment. Because the beads of red sandalwood will also sink, the agarwood is also sinking, but the highest grade of Qi Nan is half-sinking and half-floating. Therefore, this method can only be used as a reference. It cannot be used as a standard.
The third type is "soil sinking." The agarwood of Vietnam comes from the original swamp, and some of the surface of the swamp has dried up, while the bottom is still moist. The same piece of agarwood, the upper part is the soil sinking, the lower part is the water sink is not strange. Therefore, sometimes the sinking is very different from the water and sedimentation. If it is divided, it is only the difference in efficacy and taste. Identification of the second-level "soil" bracelet:
(1) Look: "Soil sink" is generally black, only three levels below is black and gray. Generally, the second level is already very dark, reaching the level of pure black, and the gray point should be judged as level three. In addition, the secondary pores are more delicate, but the secondary soil sinking is not as fine as the secondary water sinking, but the pores of the secondary soil sinking can be covered with a little oil, and the pores of the secondary soil can not be required and the secondary water Shen is so delicate.
(2) Smell: The second grade sinks, the taste is thick and heavy, and it has a mellow feeling. It can't be too strong. If it is too strong, it may be that the ant sinks and pretends to taste like Chinese medicine. The second-order soil sinking can also be judged by judging the “drillingâ€, “transparent†and “putting†of the water sink. The taste of the soil sinking feels so fine that it should not be soaked, but it must be revealed. The taste of sinking is not intermittent.
(3) Touching, even if the material of A+ is not reflective of the grease, the surface of the bead can feel the bump, which is the feeling that the grease accumulates in the pores.
(4) Submerged, the sinking agarwood is also submerged.
