Turquoise is a water-bearing phosphate mineral of copper and aluminum. This jade material has a certain degree of porosity. It directly affects the physical properties of turquoise. The porosity of turquoise causes it to have a certain adsorption capacity, and it is easy to adsorb some dirt, such as dust, cosmetics, liquids, grease, etc., so the color of turquoise is easy to change. The large porosity makes turquoise poor in stability and difficult to polish and cut. Therefore, reducing the porosity of turquoise is the most basic principle of all turquoise optimization methods. The following describes the common and popular turquoise optimization treatment methods on the market in recent years. 1. Glue injection and filling Glue injection is also called potting, adding glue and injection molding. It is generally aimed at low-end turquoise materials, especially those foam pine with large pores that can be used as chalk, that is, surface pine, because these materials cannot be processed and used without glue. Under high pressure conditions, the high molecular polymer, that is, glue, is fully penetrated into the pores of turquoise, which greatly improves the toughness of turquoise, so that subsequent processing can be carried out. Second, dipping filling Dipping is also known as Qinjiao. In recent years, the common processing method on the market echoes the players’ pursuit of raw turquoise. In recent years, the turquoise market has continued to heat up, and people’s awareness of turquoise has also continued to improve, and they have begun to reject the injection of turquoise. This technology of dipping has emerged in this environment. The so-called dipping is to put turquoise in a rubber polymer and soak it under normal temperature and pressure. After a period of time, the glue can penetrate into the shallow pores of the green pine raw material, thereby curing it, facilitating cutting and carving, and greatly improving the yield. This method is generally aimed at medium-quality turquoise raw materials. If this layer of glue is cut and polished during post-production, we still consider the finished product as raw ore at this time. If there is glue residue, it cannot be called raw ore. 3. Partial glue repair After turquoise raw materials are processed into finished products, some turquoise will have some pits on the surface. In order to improve the value of turquoise, common 502 glue is often used to The filling of the pits is usually purely manual operation. After processing, the glue filling place will be visually regarded as a colorless and transparent natural mineral inclusion body, which is very concealed Phenibut Manufacturers . Four. Iron wire fraud Iron wire is a unique feature of turquoise. We often focus on the turquoise matrix itself, and ignoring the iron wire can also be fake. The iron wire mentioned here is not the kind of “fake” decorative iron wire on the market, but an iron wire designed to cover up surface cracks and potholes, thereby increasing the value of turquoise. Master fraudsters can make iron wire very realistic, enough to cover people’s eyes. If it is a chain of bracelets or a few iron wires on a necklace, it is even more difficult to detect, and this is a common method of some unscrupulous merchants. Unfortunately, this is often ignored by buyers who do not understand. . Five, color optimization The color of turquoise has always been a strong focus of people, so color optimization also has its survival conditions. The simple color processing is not stable and easy to decolorize. It has basically been eliminated on the market now, and more complex processing methods on the market. The turquoise is optimized with tinting glue, which guarantees that the green is changed. The color of turquoise also improves the porosity. This treatment makes the color stability of turquoise extremely high. Six. Zakri method This method is named after the scientist who developed this method and has applied for a patent, so there is very little information in this area on the market. The Zakri method is said to replicate the change process of turquoise in the deposit environment, change the microstructure of the sample, do not use organic or inorganic dyes, do not add metal ions, and do not inject glue class. After comparing the treated turquoise and natural turquoise, it is found that Zakri method has made overall treatment for porosity, surface treatment for color, and at the same time surface treatment for overall porosity and color. Zakri method is aimed at mid-to-high-end turquoise, and it has little effect or meaning for low-quality turquoise. This method is called “electrolysis method” and a similar method is imitated by domestic research. Seven, waxing This is a traditional processing technology, which refers to melting the wax at high temperature and soaking turquoise. Different from glue injection and dipping, because it does not strengthen the texture of turquoise, it may not be explicitly stated in the national standard as a treatment method, but it is also an optimization. ——————————————- ————————————— As the so-called “Magic “One foot high and one foot high”, every optimized Phenibut Suppliers turquoise also has its corresponding detection method. The following are divided into categories. 1. The identification of turquoise dipped with glue Let’s start with the most scientific and accurate point of view: Infrared spectroscopy test: in infrared Under spectroscopic conditions, polymer compounds are almost “dead by light” and can be easily distinguished from the spectrum. Refractive index: The refractive index of the injected turquoise is generally lower than 1.6, which can’t reach the refractive index of high-quality turquoise, so it seems that it lacks the high light perception and the feeling of the porcelain surface. Density: The density of turquoise optimized by injection and dipping is low, which contradicts its gorgeous color, because the darker the color of natural pine, the higher the density. Hardness: The hardness of turquoise injection and dipping will be lower than that of natural turquoise of the same grade. It is more prone to scratches and even flakes when it is carved with a blade. The following are the commonly used detection methods in actual situations: Fire: The turquoise treated with glue and dipped with fire will produce a pungent smell, which is the smell of glue melting , The surface will be accompanied by burn marks. Many people, including myself, oppose this approach. It’s just about injecting glue. If it’s true, it’s a big loss. Some people say that the hot acupuncture method is used instead, but the hot acupuncture method does not achieve the desired effect at all, especially Polish the surface after injection. ⑥Color: The market is full of rubberized ring noodles and beads. The color is highly uniform, much like the turquoise produced by the American Sleeping Beauty, but compared to natural raw mineral products of the same quality , The color will appear old-fashioned and dark. But the difference is very small, and it is difficult to judge without considerable experience. ⑦Gloss: The gloss of most glued and dipped products is very dim and unnatural, but there are a few well-crafted products that can achieve glass gloss. ⑧ Water soaking: suitable for low-end turquoise. Soak part of the turquoise in water. After a period of time, check if there is a water line. If there is any indication, it is natural turquoise. But for natural turquoise of high-quality high-porcelain, due to its high density, water molecules are difficult to penetrate, and water lines will not appear. ⑨Hand grip: Natural turquoise will feel sticky when held by hand, but it is only suitable for low-end turquoise. High-qua Phenibut on sale lity turquoise is difficult to distinguish by this method. ⑩High magnification lens: Use a high magnification magnifying glass to observe the surface. The glued turquoise appears fuzzy and distorted due to the glue covering the surface. Many white spots can be seen in the industry. After processing, the boundary structure of the enclosure can be clearly observed. This method is also suitable for replenishing turquoise, just observe the part. Fluorescence reaction of gum turquoiseSecond, the iron wire fake turquoise Identification The detection of iron wire is mainly to observe by magnification. The thickness direction of natural iron wire is irregular and the distribution is natural, while the thickness direction of artificial iron wire is very uniform and rigid. There are also artificial iron wires that are very granular and do not meet the characteristics of natural iron wires. In addition, the location where the wire suddenly thickens is often suspected of fraud. The presence of air bubbles and even transparent iron wires are false iron wires. Legend of iron wire fraud3. Identification of dyed turquoise Dyeing is mainly detected by magnification observation and UV photometer. Dyed turquoise is often distorted in color, and you can see the dye deposits in the pits when you zoom in. An ultraviolet photometer can detect a certain absorption band on the spectrum of the dyed turquoise. The color is distorted, and the concave part is dyed and precipitated4. Zakri process green Identification of turquoise Due to its rigorous scientific nature, the Zakri method does not apply to the turquoise treated with it in laboratory testing methods, but it can still be judged by the following characteristics, but this method also Only suitable for a few experienced turquoise veterans. Color and gloss change: Different from the optimization of glue injection, the surface gloss of turquoise treated by Zakri is not dim, but stronger than natural turquoise of the same quality. When you encounter a high degree of consistency in the gloss and color between the bracelets and necklaces, and you can’t judge there are other problems, you should consider Zakri, because the possibility of this phenomenon in natural turquoise beads is almost zero. Fracture observation: The turquoise fissures treated by Zakri will have color enrichment, not only in the fissures, but also in the edge of the fissures. The trace element test is mainly judged by detecting the change of potassium content. The potassium content is too high, and most of them are processed by the Zakri method. The above has summarized some optimization and identification methods of turquoise on the market. If there is something wrong, you can point out and discuss together. The next article will tell you about the fraud and identification of turquoise. .

Currently, liquor on the market is mainly produced by three methods. One is that it must be brewed with full-grained, fresh, high-quality sorghum, rice, wheat, glutinous rice and other grains as raw materials for winemaking through a series of traditional techniques. Pure grain solid-state liquor; secondly, fermented liquor is made from dried potato, corn, molasses, straw, etc., and after the edible alcohol is produced, it is then reduced and blended into liquid liquor; the third is the front The mixture of the two is a solid-liquid liquor blended with no less than 30% solid liquor and edible alcohol. At first glance, all three are just a mixture of alcohol and water, but due to the different brewing materials and processes used, their production costs and the comfort of drinking for consumers are also different. Among them, the solid liquor is the most popular, while the liquid liquor is easy to get on the head and dry mouth after drinking, which may cause a hangover, which is not conducive to the current concept of healthy drinking and is shunned by consumers. But if you study the brewing process of foreign wines carefully, you will find that foreign distilled liquors such as whiskey, vodka, brandy, and rum are actually made of barley, potatoes, molasses or grapes as raw materials, with yeast added The saccharification starter is fermented by liquid fermentation, distillation, dilution, and finally stored in oak barrels. Then, it is also the distilled liquor obtained by liquid fermentation. Compared with the openness, it advertises itself as liquid fermentation Buy Phenibut Online , but it also attracts foreign wines that consumers are eager to. Why do liquors have liquid fermentation? However, businesses have to conceal it. Can consumers avoid it?

Different raw materials contain different harmful ingredients

First of all, the production of edible alcohol is actually through the fermentation and purification of raw materials and distillation of alcohol solution extraction, and the used Different raw materials have different trace components in the extracted alcohol solution. If molasses is used as the raw material, the content of acetaldehyde in the obtained edible alcohol is 10-50 times that of the grain raw material;The pectin content in potato raw materials is higher, which will be converted into a large amount during fermentation. Methanol, resulting in excessively high methanol content in edible alcohol. And when cassava is used as raw material to produce edible alcohol, hydrocyanic acid and other cyanides will be produced during the brewing and fermentation process; while excessive amounts of trace components such as acetaldehyde, methanol, and hydrocyanic acid, the lighter ones will lead to the rise after drinking, and the heavy ones will occur. Symptoms such as poisoning are the fundamental reason why everyone “discolors when smelling alcohol”.

Foreign wine pursuing cleanliness, white wine pursuing flavor

But generally speaking, the edible alcohol produced will be further filtered, decontaminated, deodorized, and degraded, and th Phenibut on sale en based on its color , Aroma and taste are graded to control these harmful components within a certain range. For the sensory evaluation of edible alcohol, my country and foreign countries have different standards. Among them, both of the basic requirements for edible alcohol are “pure”, “pure”, “no miscellaneous smell” and “no smell”. But for smell, our country’s standard stipulates that super-grade alcohol should have “intrinsic smell of ethanol”, while Europe and America require “odorless”; and for the taste of edible alcohol, our country requires taste “Slightly sweet”, while European and American countries require “pure and tasteless”, that is, except for the smell and taste of pure alcohol itself, it cannot distinguish other evil smells. At first glance, in fact, the two requirements for edible alcohol are not too far apart, they also pursue the purity of its taste and smell. Therefore, the edible alcohol produced in the country is actually used to produce foreign wines such as vodka and brandy. However, foreign distilled liquors generally only need to store the edible alcohol after liquid fermentation in oak barrels, and finally combine different liquors for scheduling, color mixing, and flavoring. Liquid liquor only relies on edible alcohol to add water to reduce the degree, or the edible alcohol blends with each other, it is difficult to make the finished wine have a unique aroma and taste. Therefore, water and edible alcohol are removed from liquid liquor, and acids, esters Phenibut powder wholesale and other flavors and fragrances need to be added for flavoring or directly steamed with lees to optimize the taste of liquid liquor to give it a unique Liquor aroma. Therefore, although the same edible alcohol obtained by liquid fermentation method, because foreign distilled wines are more pursuing the clean taste, and the white wine needs to pursue different flavors with different body flavors, so Different treatments such as deodorization and impurity removal of alcohol and subsequent blending procedures result in different after-drinking feelings and popularity. And this is why the raw materials are almost the same, the process is the same, the liquid fermentation method is used in foreign wines, and the reason is that the liquor is shunned. So, although the liquid liquor produced by many formal wineries undergoes quality testing before leaving the factory, harmful trace components such as fusel oil, methanol, and cyanide will be controlled within a certain range. However, the flavors and spices added to create a unique wine flavor are still harmful to the human body. Moreover, its color, aroma and taste are far from the real pure grain wine. Therefore, for those with surplus money, if they like to drink white wine, it is better to choose pure grain white wine for drinking; and if they prefer the wine produced by liquid fermentation, choose a foreign wine with a relatively cleaner taste. It can be consumed. However, when choosing wine, you need to keep your eyes open, find the right channels, and be wary of those shoddy liquid liquors under the banner of “pure grain wine”.

Maca taboo 　

Experts pointed out: Women who are pregnant and breastfeeding may not be suitable for taking Maca products. Because there is no authoritative data to prove that the use of maca by pregnant and breastfeeding women will not have physical effects on the fetus or young children, so it is prudent that pregnant and breastfeeding women should stop taking maca. According to the “Food Safety Law of the People’s Republic of China” and the “New Resource Food Management Measures”, maca powder is now approved as a new resource food. The production and operation of new resource food shall comply with relevant laws, regulations and standards. 1. Maca should be taken cautiously when pregnant women and children, because so far, there is no scientific experiment to prove whether maca has an indirect effect on the fetus. Therefore, during pregnancy, You should stop taking Maca. 2. For thyroid patients, because Maca contains glucosinolate compounds, if taken in excess with a low-iodine diet, it may cause thyroid swelling. Goiter includes difficulty swallowing, coughing, breathing difficulties, tightness in the throat, and swelling at the bottom of the neck. It should also be taken with caution.

Maca side effects

The side effects of maca cannot be ignored. The maca industry advertises that maca is a pure natural herb without any side effects. This is actually quite misleading. So what are the side effects of maca? One of the side effects of Maca: Buy Phenibut Online It may cause goiter. Maca contains glucosinolate compounds. If taken in excess with a low-iodine diet, it may cause thyroid swelling. The second side effect of Maca: it may be allergic. Many people are allergic to it. Allergies are mainly caused by allergens, and everyone’s allergens are different. For example, some people are allergic to certain flowers. Symptoms of allergies include: itching, tingling or swelling of the mouth, lips or throat; rash, skin redness, itching; diarrhea or vomiting; runny or nasal congestion, red, painful or watery eyes; difficulty swallowing; coughing, Wheezing, breathing difficulties, stiff joints, fainting, and shock are all symptoms of allergies, and maca may also be an allergen for some people. Maca side effect third: it may cause skin problems. Because maca increases hormone secretion, it is not suitable for teenagers and infants to eat maca. Maca can cause skin diseases such as acne in teenagers. The fourth side effect of Maca: regulating sex hormone levels, leading to menstrual disorders and decreased libido. Many people don’t understand this. Maca can obviously increase libido. Why does it cause menstrual disorders and decreased libido? Maca is suitable for people with endocrine imbalance. If your endocrine is normal, you don’t need to take maca, because maca may increase hormone secretion and cause endocrine imbalance. Therefore, Phenibut on sale the ancients said that it is very reasonable not to take medicine without disorder. The fifth side effect of Maca: It may cause nausea and stomach discomfort. This is mainly different from person to person and has a lot to do with gastrointestinal conditions. Sixth side effect of Maca: Maca overdose can cause irritation, and people who are irritated eating maca will cause increased irritation. This amount must be controlled and good things should be taken in moderation. Maca is a kind of herb, but it should not be consumed in excess. Generally, it is very reasonable to keep it within 25 grams a day. If you consume too much, it will cause a series of bad effects.

Which people are not suitable for eating maca

Infants and young children: Although maca can be used as an energy supplement, maca has another function to improve human libido and sexual ability. This is not suitable for infants and young children, because it may lead to premature maturity. From a plant perspective, infants and young children can eat maca fresh fruit, but health foods such as maca essence tablets are not recommended for infants and young children. Breastfeeding women: Maca has the function of regulating and balancing endocrine, and endocrine disorders can lead to a series of consequences, such as rough skin, stains, etc., and many women eat maca or maca to regulate endocrine Coffee essence table Phenibut on sale ts can effectively regulate the body’s secretion and keep it in balance, so as to achieve the effect of beauty and beauty. Maca does have this effect, but it is not recommended for breastfeeding mothers to eat maca, because maca can enhance sexual desire, and whether the nutrients in maca will affect the milk composition of breastfeeding mothers, there is no definite Studies have shown that whether breastfeeding mothers eat maca and its milk will affect the fetus, in this case, for the sake of insurance, it is not recommended to eat maca. Pregnant women: During pregnancy, due to the protection of their children, they usually stop having intercourse. Maca can increase libido and improve sexual performance, which is not conducive to pregnancy protection. On the other hand, currently There is no clinical proof that the nutritional content of maca will not have a bad effect on the fetus, but for the sake of insurance, it is not recommended for pregnant women to eat maca. Patients with thyroid disease: There is a compound called glucosinolate in maca. There is more or less iodine intake in the diet, and glucosinolates combined with iodine may cause thyroid swelling , Which will have a series of effects on patients with thyroid disease. Minors: Experts believe that maca is not suitable for minors. Minors are in the developmental period and are growing up. It is recommended to eat more nutritious vegetables and fruits to satisfy growth. Need, from a health perspective, as long as the nutrition can keep up, you can generally grow up healthily. Maca faces mainly adults with endocrine disorders, reduced physical strength, and fatigue.
