How to distinguish the small leaved red sandalwood, how to identify the small leaved red sandalwood

Is it better to have a purple-red color or black color of red sandalwood? Some people see the orange leaf red sandalwood and think it is fake, and some people don't like it when they see it black, and players who have just started to contact the small leaf red sandalwood think that the dark color is the old material, and it is the real red sandalwood, which is not comprehensive.

The color of red sandalwood is purple, which is also an intuitive impression of red sandalwood, purple has always been considered a noble color. The purple in red sandalwood is noble but not flashy, it is a deep, restrained beauty, in fact, the color of red sandalwood is not the same, even the color of the same product in different periods is very different.

As Zhou Mo wrote in "Mu Jian", there are four surface colors of rosewood: crimson, this kind of rosewood has a slightly lighter specific gravity, poor oil texture, dry hair, crimson color, and few gold wires of Venus; Deep purple, dense texture, heavy weight, strong oiliness, difficult to see texture, dense Venus gold filaments; Purple black, the surface of this kind of rosewood is black, and the light is obvious. This kind of wood is very rare, and it is the best grade in red sandalwood; Purple yellow, this kind of red sandalwood is generally artificially introduced, with a large diameter and few cavities.

The color of the small leaf red sandalwood in different periods is also very different, when the small leaf red sandalwood products are just opened, the color is orange yellow or orange red, according to the different material quality, the color will be slightly different, some yellowish, some reddish, but the whole is orange red, but with time precipitation, air oxidation, gradually deepening, blackening, because the red sandalwood contains pterosandalwood, so it is easy to dye the gloves red, but if properly maintained, the deep purple is full of charming red luster; If you are sweated for a long time, it is easy to turn black, and there is no luster and texture at all. Therefore, the color of the small leaf red sandalwood is dark or light, black or yellow has nothing to do with the quality, it can only be said how long it is put after it is done, and the color does not determine the quality of the quality.

(1) Alcohol experiment Because the red sandalwood contains a large amount of crimson pterosandne, when the wood blocks or sawdust of the red sandalwood are put into the liquor, a large amount of crimson pterostilbene will overflow, and a sticky gelatinous substance will be formed between the surface of the red sandalwood and the liquid, and the pouring can be connected into a line, of course, this experiment is mainly to verify the existence of pterosandalwood, and it does not mean that it is pterosandalwood.

b) Fluorescence reactions.

If you use small leaf red sandalwood, soak it in water for more than 12 hours, and generally there will be a more obvious fluorescence reaction after 24 hours: when the light and the eye are at an angle of 45 degrees, you can see a layer of fluorescence floating on the cup like engine oil. This identification method is the easiest to master and more accurate.

This step can be used to exclude other sorrel woods such as Rosewood (Pterodium macrophylla) and non-Pterostilbene species.

3) Paper stroke test.

Scratch on the white paper with wood chips or beads, if the color of the red sandalwood is different according to the length of oxidation time on the surface, it will make purple-red to orange-yellow scratches on the white paper. However, this is not the only effective way to identify red sandalwood, because there are similar situations in other known woods, such as red acid branch and blood sandalwood also have nearly the same performance after this experiment, although there are differences, but it is still difficult for novice players to identify.

4) Submersion experiment.

The specific gravity of red sandalwood is greater than 1g cm, so that it can sink in water, so whether it is a piece of wood or a bead, if it is red sandalwood, it will be able to sink into water, which is one of the cheapest ways to identify red sandalwood. However, it should be noted that in addition to red sandalwood, there are many woods that can also be submerged, so it cannot be used as an absolute method of identification. The same is some red sandalwood products, such as red sandalwood beads with a smaller diameter, materials with a density difference of bran, punching or waxing, surface tension and other physical factors, which will also appear to be non-sinking.

5) Fragrance identification: Small-leaved red sandalwood, so there is almost no taste, and there will be no aroma when you smell it directly, let alone sourness. If you have to talk about the taste, it is the fragrance of wood, which is more obvious when processed and polished, and the finished beads have no taste. One way to smell is to rub your hand and immediately put it on your nose to smell a faint fragrance, but most people's noses are not as sensitive.

The second method can take a wire or needle after heating, put the beads into the wire to smell, the wood in the bead hole contact the heated wire, the smell is more obvious, the smell is very strong and very nasal is definitely not the small leaf red sandalwood, if there is acid gas either other wood, or it is the chemical smell left after the dye dyeing. The taste of blood sandalwood is greater than that of small-leaved red sandalwood, and it has a partial medicinal taste. This method is simple and does not harm the beads themselves.

The above experiments are mostly destructive, and are not suitable for the operation of the purchase of red sandalwood products, you can observe the growth lines on the section when purchasing red sandalwood, if the red sandalwood growth lines are fine, regular and not obvious, and then we can observe its duct (zongyan), if it is red sandalwood, it is usually more curly like cow hair, so it is also described as cow hair lines. Bovine hair patterns are often used as an important feature in the identification of red sandalwood. 

Answer 1: Observe its color first, the small leaf red sandalwood is orange before it is oxidized, and with the increase of contact time with air, it begins to oxidize, and it will become purple, and the color will change with the oxidation time.

2. Observing the lines, the growth lines of small-leaved red sandalwood are there, which are much shallower than ordinary wood. Because the growth rate of small-leaved red sandalwood is relatively slow, the wood is very delicate, and those rough ones are either blood sandalwood or artificial fast-growing red sandalwood forests. Even if it is definitely Pterostilbene, we would be willing to choose less growth lines.

3. Smell the taste, the small leaf red sandalwood is a fragrance, which makes people feel very stable. If the taste is fragrant, then it is fake. You can heat the wire and put it into the hole of the bead so that it does not hurt the bead and still smells distinct.

1. Small leaf red sandalwood bracelet.

Nowadays, many middle-aged and elderly people like the bracelet of small leaf rosewood, which is not only harmful to the body, but also calms the mood and is beneficial to life. Moreover, the small leaf red sandalwood bracelet also has a certain collection value, and it is also beneficial to the blood circulation of the opponent when often playing with it.

I sent a ** to ask a question, can you see it?

I sent a **, can you see it.

You can't see the questions.

How about this condition, how much can it be worth, how many A's.

First of all, the most reliable way to identify the small leaf red sandalwood bracelet is to smell its taste, and then directly distinguish the authenticity of the small leaf red sandalwood bracelet from the surface, texture, density (quality).

1. The specific gravity of red sandalwood is greater than that of water, and the small leaf red sandalwood will sink into water when put into water.

2. Take a piece of wood and scratch it on white paper, if it is a small leaf red sandalwood, there are orange scratches.

3. Put the red sandalwood block into a container filled with alcohol, and red pterostilbene will seep out of the red sandalwood in the form of smoke.

4. Look at the growth wheel on the cross-section, if it is red sandalwood, the growth wheel is not obvious; If the growth ring is not obvious or difficult to determine, proceed to the next step.

5. Look at the surface color. If it is red sandalwood, the new section is orange-red, and for a long time, it is dark purple or purple-red, often with black tendons.

6. Smell the aroma, if the small leaf red sandalwood has a very weak fragrance when rubbing with the object (like the fragrance of sandalwood, but not the same as the incense smelled in ordinary life), the smell is very strong when filing with a file and a table saw.

7. Look at the texture. If it is red sandalwood, the texture is staggered, and some parts are curled (cow hair pattern).

8. Look at the texture of the oil. If it is a small leaf red sandalwood, it has an oily texture; If you can pass, move on to the next step.

The method of identifying the small leaf red sandalwood: look at the brown eye, weigh it, smell the taste, and look at the color.

Clause. 1. Look at brown eyes.

This is the first step of visual observation, and it is easy to see clearly, that is, to see if there is a slender brown eye on the bead, also known as cow hair pattern, it is a wooden conduit, and the brown eye is very obvious on the small leaf red sandalwood, and it is also one of its main characteristics, but according to the relationship between the new and old materials, there will be more and less, thick and fine, if there is no brown eye at all, then rest assured, it is definitely not small leaf red sandalwood! Of course, there are a lot of wood with brown eyes, so we have to move on to the next step.

Clause. 2. Weighing.

This step can be done with an electronic scale, the density of small-leaf red sandalwood is very high, and the density of most fake wood cannot be reached, so it can filter out a large number of fake red sandalwood. Of course, the premise is that the specifications should be standard, for example, under the standard size, the small leaf red sandalwood bracelet is about 35g for 15mm 15 pieces, about 52g for 18mm 13 pieces, and about 65g for 20mm 20 pieces. In order to increase the weight, some merchants will add a bead to the string, back cloud or something, and even deliberately make the size of the bead 1-2mm, and the weight will go up, creating the illusion that the density is high enough.

In addition, to see whether the skewers are submerged, it is also an effective way to measure the weight density, the small leaf red sandalwood can be sunk, and some low-density counterfeits can also be excluded, but the sinking does not mean that it must be the small leaf red sandalwood!

Clause. 3. Smell the smell.

This needs some experience, although it is called "sandalwood red sandalwood", but to be honest, the fragrance of small leaf red sandalwood is not obvious, and the so-called sandalwood, one of the four famous incense, is far away, it itself just has a very light taste, it is more obvious when processing and grinding, and the finished product will also be lost, if it is oxidized slurry, the taste is almost nothing. Some foodies say that the small leaf red sandalwood tastes like chocolate, and this metaphor is quite reliable. If the taste of the skewers is sour, very strong, fragrant or even pungent, it is definitely not small leaf red sandalwood!

Although the method of smelling is more subjective, it is also an important basis for more exposure.

Clause. Fourth, look at the color.

The freshly made red sandalwood is orange-yellow, and with the oxidation of the air, the color will gradually deepen, slowly turning red, dark red, purple, and black, which takes time to verify. By the way, the color of the small leaf red sandalwood has nothing to do with whether it is new or old, it is just the difference in the length of oxidation time. If the color does not change at all for a long time, either the surface of the bead is coated with something, or it is not a small leaf red sandalwood!

Regarding the identification of Pterostilbene, this blog saw that many netizens on the Internet have listed all the ways, all of which are good methods, but they do not seem to be practical, for example, according to the submersion characteristics of Pterostilbene, put the bracelet into the water to try to see if it sinks; Another example is to scrape some wood chips down and put them in water to see if there is fluorescence, or put in alcohol to try to see if there is any pigment oozing from pterosandalwood. Of course, these methods can identify whether it is small-leaved red sandalwood, but the damage is too great, and a string of small-leaf red sandalwood bracelets will be basically tossed and scrapped by you after so many rounds. So the non-destructive selection method:

The first is to look, look at the color, look at the texture, see whether the color is red or a certain color in the pulping process, and then see if there is a cow hair pattern (the bracelet is generally not obvious); The second is to touch, touch the feel, weigh the weight, whether the oil weight is delicate; The third is to smell, smell whether there is the fragrance of sandalwood and red sandalwood; If the boss allows, take the small leaf red sandalwood bracelet and scratch it on the white paper to see if there are red marks, if there is, it is true. The above methods can basically be identified, but they must not be too dogmatic, such as the last white paper to draw this method, a lot of dyed beads, such as dyed sour branch wood bracelet, it is also a paper with imprints.

Therefore, the first time you buy a small leaf red sandalwood bracelet, this blog still recommends that you must find a trustworthy merchant to buy, and you must not be cheap; Another is to learn more, see more, smell more, touch more, naturally, you will slowly understand the line, over time, you will be able to practice a pair of fiery eyes.

Two: Take a piece of wood and scratch it on the white paper, if it is sandalwood rosewood, there are purple-red scratches, use the same strength to draw the second time, and the third time ......, the scratch fades to disappear; If there are scratches, proceed to the next step.

Three: take the sawdust and put it in a glass filled with water (the ratio of sawdust to water: the volume ratio is about 1:

3 - 1:10), if it is sandalwood red sandalwood, the top layer of water can be seen after 12 hours (visual effect: the top layer of water and the most obvious near the glass wall) has blue oil-like fluorescence, and the fluorescence is more obvious after 24 hours, this step is mainly used to exclude other sour branches and non-red sandalwood wood such as Lu's black sandalwood; If there is fluorescence, proceed to the next step.

Four: Observe the color of the sawdust water leaching solution in the previous step. If it is sandalwood, red sandalwood is purple red (the depth of color is closely related to the part of the material, the amount of water and the length of soaking time); If it's fuchsia or not good, it's not sure to move on to the next step.

Five: look at the distribution of pipe holes on the cross-section. If it is sandalwood and red sandalwood, the diameter of the tube hole in the whole growth wheel is slightly equal and evenly distributed; The cross-section can be cut with a sharp knife, it is best not to return the knife, ** can be coated with some water, it is best to use a ten-fold magnifying glass or a higher magnifying glass to observe; If the distribution is more uniform or not good, it is certain to move on to the next step.

Six: Look at the growth wheel. The growth wheel was observed in the cross-section, and if it was sandalwood and red sandalwood, the growth wheel was not obvious; If the growth rings are not obvious or not good, be sure to continue with the following four steps.

Seven: Kanban surface material color. If it is sandalwood rosewood, the new profile is orange-red, and for a long time, it is dark purple or black-purple, often with light color and purple-black stripes.

Eight: Smell the aroma. If sandalwood red sandalwood has a very faint fragrance when rubbing with objects, it has a very weak fragrance (like sandalwood fragrance, but not the same as the burning incense we smell in our daily life), and the smell is very strong when filing with a file and a table saw.

Nine: Look at the texture. If it is sandalwood and red sandalwood, the texture is staggered, and some parts are curled.

Look at the texture and color of the small leaf red sandalwood, cow hair pattern, Venus are typical characteristics of red sandalwood, but do not mistake the conduit of other wood for the cow hair pattern of red sandalwood, the key is to see more of the real thing, see more and find the feeling of identifying the red sandalwood pattern.

Eleven: 30x magnification of the cross-section. This is the last step of personal identification, in the three sections of the wood, the cross-section provides the most abundant information, to carefully observe the characteristics of the cross-section, compared with the description and ** in the national standard "Mahogany", if it is sandalwood red sandalwood is consistent (if there is no condition this step can be omitted).

If you can pass the above 11 steps of the inspection can be determined that this wood is sandalwood rosewood, if any of these steps obviously do not meet the judgment is not sandalwood rosewood, if there are still doubts, you can take a sample (mahjong size) sent to the relevant departments (such as the Chinese Academy of Forestry) to do wood species identification.
