Question 2: Can dushan jade original stone be smeared with edible oil? Yes, vegetable oil is the best.

Question 3: How does dushan jade maintain hello?

Dushan jade's maintenance methods are as follows.

1 Avoid collision with hard objects. Although the hardness of jade is high, it is easy to crack after collision. Sometimes, although cracks can't be seen by naked eyes, the molecular structure of jade surface has been destroyed and dark cracks appear, which greatly damages its perfection and economic value.

2 try to avoid dust. If there is dust in daily jade articles, clean them with a soft brush. If dirt or oil stains are attached to the jade surface, it should be scrubbed with mild soapy water first, and then rinsed with clear water. Do not use chemical degreasing agent solution.

When not in use, the pendant should be properly put away, preferably in a jewelry bag or jewelry box to avoid scratches or damage.

Try to avoid contact with perfume, chemical liquid, soap and human sweat. As we all know, sweat contains salt, volatile fatty acids and urea. If jadeite is not cleaned immediately after wearing, it will be eroded, destroy the outer layer and affect the original brightness.

Avoid long-term direct sunlight, and jade articles should avoid exposure to sunlight, because when jade meets thermal expansion, its molecular volume increases, which will affect jade quality.

Yu Pei pendants should be wiped with clean and soft white cloth, which will help to keep and maintain the original quality. Dyed cloth and fiber hard cloth are not suitable.

7 Jade should maintain proper humidity, and the quality of jade should be maintained by a certain humidity. If the surrounding environment does not maintain a certain humidity and dryness, the natural moisture in it will easily evaporate, thus losing artistic and economic value.

I hope the answer can help you.

Question 4: I bought a piece of Nanyang jade with oil on it. How to clean with detergent?

Question 5: How does dushan jade keep white after washing with oily detergent? Jade articles should be maintained with oil. Use skin care oil (we use olive oil). Thank you. I hope to adopt.

Question 6: How to clean Du Yu? Wipe with a clean and soft white cloth. Dyed cloth and hard fiber cloth are not suitable. Jade jewelry inlaid with diamonds, rubies and emeralds. Only clean white cloth can be used to wipe off oil, dust, impurities, moisture or sweat, which will help to maintain and maintain the original quality.

Are you satisfied with the above answers?

Question 7: How to maintain jadeite to make it more shiny?

The ancients talked about raising jade, and the word "raising" not only shows that jade is a living substance, but also contains a lot of knowledge. To sum up, there are roughly the following points:

1 to avoid collision with hard objects. Although the hardness of jade is high, it is easy to crack after collision. Sometimes, although cracks can't be seen by naked eyes, the molecular structure of jade surface has been destroyed and dark cracks appear, which greatly damages its perfection and economic value.

2. Avoid dust as much as possible. If there is dust in daily jade articles, clean them with a soft brush; If dirt or oil stains are attached to the jade surface, it should be scrubbed with mild soapy water first, and then rinsed with clear water. Do not use chemical degreasing agent solution.

3. Put away the pendant when not in use. It is best to put it in a jewelry bag or jewelry box to avoid scratching or damage. If it is high-grade jade jewelry, don't put it on the counter to avoid dust and dirt, which will affect the brightness.

4. Try to avoid contact with perfume, chemical liquid, soap and human sweat. As we all know, sweat contains salt, volatile fatty acids and urea. If jadeite comes into contact with too much sweat and is not wiped clean immediately after wearing, it will be eroded, destroy the outer layer and affect the original brightness. In particular, "glass species" of jadeite and suet white jade, avoid sweat and grease. Many people think that the more jadeite touches the human body, the better it will be moistened with sweat. In fact, this is a big misunderstanding. Jade is different from ancient jade. Ancient jade needs the help of the process of birth and human body temperature. The jade in the "glass ground" itself is crystal clear, so there is no need to use any method and there is no way to make it more transparent. If you sweat too much, sheep fat white jade will easily turn pale yellow and no longer be as pure white as fat.

5. Avoid long-term direct sunlight. Jade should avoid exposure to the sun, because when jade encounters thermal expansion, its molecular volume increases, which will affect its quality. Especially hibiscus jade, crystal, agate and so on. It will burst when it encounters high heat, so it is even more taboo to be close to the heat source.

6. The pendant should be wiped with a clean and soft white cloth, and it is not advisable to use dyed cloth or fibrous hard cloth. Jade jewelry inlaid with diamonds, rubies and emeralds. Only clean white cloth can be used to wipe off oil, dust, impurities, moisture or sweat, which will help to maintain and maintain the original quality.

7. Jade articles should keep proper humidity. Emerald depends on certain humidity to keep it, especially water bile agate and crystal jadeite. During the formation of water bile agate, there was natural water in it. If the surrounding environment does not maintain a certain humidity and dryness, the natural moisture in it will easily evaporate, thus losing its artistic and economic value.

A beautiful jade needs maintenance. If it is well maintained, it will not lose its former beauty and elegance, because when jade is underground, it has nutrients endowed by nature, is full of moisture and is not dry. The last process after the completion of the jade piece is the beauty of the jade piece. She needs to be coated with a layer of high-grade protective wax to raise and protect jade. A jade body is absolutely the same as a human skin. The living environment of jade articles must be wet. Some jade pieces look dusty and dry, and need to be cleaned and nourished regularly. I introduce a maintenance method to my friends.

Add water to the pot and put the jade pieces on it like steamed bread. After steaming the jade pieces, take them out with a clean cloth pad instead of a chemical fiber cloth, brush off the gray marks on the jade while it is hot, and then apply a thin and even layer of high-quality wax. [It is best to use high-quality pure wax] Wax can also be used. Apply the melted wax evenly with a brush. After the jade piece is cooled, wipe it with a raw white cloth.

In ancient times, jade was so widespread: emperors wore jade to show providence, literati wore jade to show nobility, gentlemen wore jade to show virtue, and people wore jade to show good luck. Jade is cherished by people because of its excellent characteristics. The Chinese nation is a nation that loves jade, and jade is widely used for sacrifice, burial, decoration and wearing. "Better be a broken jade" and "Jade has nine virtues" personify jade and make it a symbol of virtue. The priceless legend of He Bi's strange fate is fascinating, and so on, forming a splendid jade culture that has lasted for thousands of years. Like beautiful jade, it shines brightly and attracts people's attention in the long history of splendid Chinese civilization.

Question 8: How should jadeite be maintained? Jade is the beauty of stone, and everyone loves it. In ancient times, jade was so widespread: emperors wore jade to show providence, literati wore jade to show nobility, gentlemen wore jade to show virtue, and people wore jade to show good luck. Jade is cherished by people because of its excellent characteristics. The Chinese nation is a nation that loves jade, and jade is widely used for sacrifice, burial, decoration and wearing. "Better be a broken jade" and "Jade has nine virtues" personify jade and make it a symbol of virtue. The priceless legend of He Bi's strange fate is fascinating, and so on, forming a splendid jade culture that has lasted for thousands of years. Like beautiful jade, it shines brightly and attracts people's attention in the long history of splendid Chinese civilization.

First, the category of jade.

Generally speaking, all beautiful stones that are naturally formed and can become delicate and smooth, bright in color, tough in texture and stable in chemical properties after processing can be classified as jade. Generally speaking, nephrite and jadeite are the main products.

1. Precious jadeite jade belongs to pyroxene, mainly composed of sodium aluminosilicate, with hardness of seven degrees, slightly higher than nephrite, and specific gravity of 3.33, slightly higher than nephrite. Emerald is a fibrous dense body with blue fine crystals or cryptocrystals, which is very tough and not easy to break after being hit hard. Its color is caused by the type and quantity of metal impurities, which makes the color of jadeite ever-changing. The colors of jadeite are basically different shades of green, red, yellow, white, gray, black and purple. Emerald is the most precious, with the most economic value and collection value.

2. Soft Hetian Jade Xinjiang Hetian Jade is also called "nephrite", commonly known as real jade. "Jade" in a narrow sense only refers to Hetian jade. The scientific name of Hetian jade is tremolite-actinolite mineral with hardness of 6-6.5 and specific gravity of 2.96-3.17. Because it is particularly hard, it generally does not "eat a knife" and can be used to cut glass. Because the proportion is heavy, dense and powerful, it gives people a heavy feeling, which experts call "enough hands". Microscopically, Hetian jade has a filamentous structure like mica, so Hetian jade has a certain toughness and emits warm and soft fluorescence. The following briefly introduces several kinds of hetian jade.

White jade nephrite is the most precious one, and the best one is as white as white fat, which is called "white jade with sheep fat". Sheep fat white jade is white, transparent, delicate and moist. It is white in itself and warm pink through light.

Jade jade is mainly cyan, but there is also a small area of sugar color (yellow or brown) in the primary color. This kind of jade is called sugar jade, which is very valuable in jade carving and is very popular.

Jasper color from light green to dark green, common colors such as spinach, slightly transparent. Generally, jasper has black spots and light color, which is mistakenly called "vegetable jade" and is a second-class product of Hetian jade. A good jasper is like jade, which is easily confused with jade at first glance, but its black star characteristics and its green color are completely eclipsed by the light, which is completely different from jade.

Ink jade is generally dark gray, and it is extremely rare to be really pure black as paint. Most black jade is similar to sapphire. Jasper is a precious jet when its impurity content is high and it is black. It's black as a speck of sesame, or like a flake of dark clouds. Its names are Dark Clouds, Light Ink, Beauty Temple and so on. The black and white contrast of jet is strong, which can be used as a work of clever colors. Gold and black are mostly used to make utensils for pressing gold and silver threads.

Topaz nephrite is a very precious variety, harder and opaque than white jade, with more light colors and less strong colors. There are chicken yellow, dense wax yellow, chestnut color, osmanthus yellow and so on. And the output is very small.

Ruby varies in color from light red to deep red, and is generally soft and thick white jade leather, so the material is extremely small, and only flaky products have been seen. Ruby is bright red and moist, which is extremely rare.

3. Other traditional jade

Nanyang jade is produced in Dushan, Nanyang, Henan Province, also known as dushan jade. The composition of Nanyang jade is "altered gabbro", which is mainly composed of calcium aluminosilicate and contains many mineral elements. Its hardness is 6 ~ 6.5, which is equivalent to jadeite, and its specific gravity is 3.29. The quality of Nanyang jade is mainly determined by color and transparency, and the best is a slightly transparent blank in white and green.

Lantian jade and lantian jade are nephrite, which are produced in Yuquan Mountain, Lantian County, Shaanxi Province. It belongs to serpentine diopside mineral. Its composition is mainly silicon and phosphorus, and the color of jade is white and gray-blue. White is the best, and it has glass luster after polishing, with a specific gravity of 2.98.

Xiuyan jade is produced in Xiuyan County, Liaoning Province. The main mineral is serpentine with hardness of 2.5 ~ 5.5 and specific gravity of 2.5 ~ 2.8. The texture is even and delicate, and the water head is sufficient, but it is soft. Xiuyan jade is currently mined the most, and its color is the same as nephrite, including white, cyan, yellow, light yellow, pink, light green and emerald green. And it is translucent to opaque.

Jiuquan jade is produced in the mountainous area near Jiuquan, Gansu ... >>

Question 9: What are the characteristics of dushan jade? Dushan jade is a kind of multicolored jade, which can be divided into eight varieties by color. ① Green dushan jade: green to emerald green, translucent, delicate in texture, similar to jadeite, with glass luster. ② Red dushan jade: also known as "Furong Jade". The color is light red to red, with fine texture and good luster. ③ White dushan jade: white or off-white, with fine texture and oily luster. Its varieties include cream white jade, permeable white jade and so on. ④ Purple dushan jade: The color is deep purple, with poor transparency. ⑤ Yellow dushan jade: Yellow-green. ⑥ Black dushan jade: The color is like ink, so it is also called "jet". ⑦ cyan dushan jade: The color is cyan and the transparency is poor. 8 Miscellaneous dushan jade: Miscellaneous dushan jade. Dushan jade has the best color, high transparency, fine texture and no impurity cracks. Among them, hibiscus stone, permeable white jade and emerald are of high value. In addition, the use of jade blocks of different colors to imitate the natural beauty of jade carving has also been well received. According to the research of Henan geologists in recent years, Nanyangyu is an altered plagioclase, which consists of zoisite, epidote, tremolite, sericite, biotite and sphene. Through microscopic identification, jade contains a variety of altered minerals, mainly zoisite, epidote and tremolite. Because jade contains all kinds of metal impurities, there are many colors of jade, mainly green, white and variegated, as well as purple, blue and yellow. The hardness of Nanyang jade is 6 ~ 6.5. With glass luster, most of them are opaque and a few are slightly transparent. The results of chemical analysis are as follows: silica 4 1 ~ 45%, alumina 30.7 1 ~ 34. 14%, magnesia 0.28 ~ 1.73%, potassium oxide 0.02 ~ 2.64% and iron oxide 0 ~ 0.8. The trace element analysis results of Nanyang jade are as follows: Cr 0.0 1 ~ 0.5%, Ni less than 0. 1%, v0.001~ 0./%,Mn 0.0 1 ~ 0.05%, Ti 0. According to written records, there is no doubt that Nanyang jade was mined in the Han Dynasty. Recent archaeological data pushed the exploitation of Nanyang jade before the late Shang Dynasty. 1952, Li Ji pointed out that there were 444 bladed stone tools in Yin Ruins, including 7 jade articles, all of which were made of Nanyang jade. The excavation report of No.5 Tomb of Yinxu in Anyang also pointed out that more than 700 jade articles were unearthed from Muhao Tomb of Yinxu, and more than 40 specimens were preliminarily identified. "Most of them are close to modern xiuyan jade in Liaoning, a few are close to Nanyang jade in Henan, and a few are similar to Hetian jade in Xinjiang." (Journal of Archaeology, No.2,1977)1At the gem lecture and academic exchange meeting in Chengdu, Sichuan Province in June, 1983, the Henan Geological Bureau said in a paper about Nanyang jade that a Nanyang jade shovel was unearthed in Huangshan, Nanyang County, and it was identified as a product of the late Neolithic Age, with a history of more than 6,000 years. Duyu is one of the four famous jade in China. Duyu mining area is located in Dushan in the northern suburb of Nanyang City, Henan Province, also known as Nanyang Valley. The sole jade is plagioclase jade, with fine texture, oily or glassy luster, good polishing performance and transparency. It is a multicolor jade composed of more than three tones, with bright color and hardness greater than 6.5. The main varieties are: white jade, green jade, green white jade, purple jade, topaz, hibiscus jade, black jade and variegated jade. Duyu mining industry has a long history. The Neolithic Longshan culture unearthed in Shenmu, Shaanxi Province is Yu Fu, and now the Yuan Dynasty "Light Mountain and Jade Sea" displayed in Tuancheng, Beihai Park, Beijing is all carved by Du Yu. Duyu Mine had a considerable scale in Han Dynasty. Up to now, there are more than 1000 ancient pits in Dushan, Nanyang, which shows that the mining of Duyu has a long history, a large scale and a rich variety.

Question 10: What is the function of Nanyang specialty dushan jade? Nanyang Duyu is one of the four famous jade in China. It is located in Dushan, 8 kilometers north of Nanyang City. It was first collected in the Spring and Autumn Period and the Warring States Period. There are more than 70 natural colors such as red, orange, yellow, green, cyan, blue and purple. High hardness, good luster, fine texture and high transparency. It is a good raw material for carving jade, and people call it "jade".

Dushan jade is a specialty of Nanyang, unique in China. Nanyang dushan jade is known as one of the four famous jade in China, with a history of more than 6,000 years. It is bright in color and warm in texture, and has long been respected by collectors, occupying a very important position in the jade market.

Dushan jade is fine and pure, with grease or glass luster, good polishing performance, transparent or slightly transparent. The hardness is 5.5 to 6.5 degrees. Dushan jade is a colorful jade. Generally, five-colored jade composed of two or more colors is brightly colored, which is called: water white jade, white jade, black and white jade, green jade, green white jade, azure jade, sapphire, bright brown jade, topaz, topaz, jet jade and variegated jade.

Varieties in dushan jade can be divided into five categories according to their colors:

White dushan jade: Mainly milky white. Gray * * * tone, pink * * * tone, slightly transparent. There are white jade, dry white jade, frost white jade, black and white jade, hibiscus jade and other varieties.

Green dushan jade: Mainly green and emerald green. There are varieties such as green jade, sapphire and azure jade, and the color is jade, translucent to slightly transparent.

Purple dushan jade: Dark green texture, covered with lavender spots, opaque. There are varieties such as purple jade and bright brown jade.

Yellow dushan jade: Even yellow-green or olive yellow-green is also called orange jade.

Mottled dushan jade: There are more than two kinds of dushan jade, including jet jade, emerald jade, cauliflower jade, five-flowered jade, medium-colored jade, spotted jade and black-flowered jade.

Among the above five categories, the most valuable ones are sky blue, transparent water white, hibiscus and emerald in Nanyang dushan jade, while jadeite has only three or four colors at most, while jadeite has only five or six colors of red, green, white and purple, which are distinct and do not have too many colors in dushan jade. So dushan jade's appraisal is very easy to do.

Dushan jade has the best color, high transparency, fine texture and no impurity cracks. Among them, hibiscus stone, permeable white jade and emerald are of high value. In addition, it is also very popular to imitate beautiful jade carvings in nature with jade blocks of different colors.

I hope it helps you.
