Jade Polishing Cloth
In the process of polishing jade, emery cloth was a commonly used tool. From the information provided, it could be seen that when polishing jade, the sand cloth was used from coarse to fine. For example, in some jade processing processes, after the grinding, according to the depth of the grinding marks on the stone surface, 600 to 2000 mesh sandpaper would be used for the final fine grinding process. The sandpaper here was similar to the sand cloth, which played a role in gradually polishing the jade surface to make it smooth. In addition, there were also special jade polishing emery cloths on sale in the market. For example, there were records of a total of 1083 jade polishing emery cloths. Also, during the polishing process, different grit sizes of oilstones (sandpaper, sandpaper) would be used to repeatedly polish the jade. The sandpaper, sandpaper, and emery cloth here had similar functions. They were all used to polish and polish the jade. Read more exciting novels for free
Polishing jade
There were many ways to polish jade, including manual polishing and machine polishing. ##1. Hand-polished 1. ** Initial Modifications ** - Using 600# - 1200#polishing sandpaper, he first used an electric tool to install a diamond drill bit to decorate the jade piece, and then carefully repaired it with a diamond file. Then, he used round sandpaper (from coarse sand to fine sand) to grind a large area. 2. ** Large Area Polishing ** - Use a cloth wheel to apply polishing paste to polish a large area. 3. ** Finishing details ** - You can use a felt grinding head to apply polishing paste for detailed polishing, or you can use a rubber grinding head to directly polish. Finally, it could be hand-polished with 1200 sandpaper and then polished with diamond powder. - For the sub-gloss process in hand polishing (Pure hand-polished, without the help of electric tools), commonly used for high-end seed material pendants. The surface of the polished jade has a very soft luster, close to the texture of the matte, suitable for pure color jade. However, under this kind of craftsmanship, the lines of the jade must be delicate, otherwise the overall beauty will be affected. The jade under the soft light process has a natural luster, emitting a faint light, and the light is smoother than the dull color. The luster of the high-light process was strong. Bracelets generally used high-light process to make the bracelet look more crystal clear. This process focused on the color of the material and was mostly used for processing Russian and Qinghai materials. ##2. Machine Polishing 1. ** Equipment and Materials ** - Buy a 300 to 500 yuan polishing machine (such as a small jewelry jade barrel polishing machine), then buy Feizhan's 320# - 8000#emery (from rough polishing to fine polishing), triangular bead polishing particles, cold light powder, grinding polishing powder, and polishing the mirror effect after polishing in the polishing machine for a period of time. - For the machine polishing of jade, the surface is coated with a layer of creamy polishing powder.(Green for Chromic Oxides, orange-red for Cerium Oxides), grind the surface with a 2,000-mesh grinding wheel, repeat it many times, then apply a brush, apply the diamond powder on the surface of the jade, and then use a hard brush to polish it. Fine work, start to polish the small places that the big tools can't. After applying diamond powder on the jade, use the hard skin to polish it, then use an ultrasonic machine to clean it. Use alcohol to wipe the parts that can't be cleaned, and then wax it (a kind of protection). You can wash off the wax with boiling water and blow it dry. 2. ** Technique Steps (Take Jade as an example)** - Roughly grinding: Use (1000 - 2000 mesh) emery to make tools of various shapes and polish them carefully and carefully. - Fine grinding: Use (1600 - 1800 mesh) emery to polish it according to the above method until it is smooth and shiny. - Bright: Use half-lived cowhide production tools to dip in polishing powder (3.5 um diamond powder) and rub it repeatedly to make the jade products bright inside and outside. - Wax: Wax is used to prevent water and dirt pollution. The polishing and polishing techniques of jade ware in different periods were also different. For example, the Neoliths used hand-polishing as the main method.(Grinding with water and fine sand), using bamboo, animal skin, or other soft materials to polish the surface. From the Shang and Zhou Dynasties to the Qing Dynasty, grinding and polishing tools of different materials were widely used for processing. In addition to the ancient method, stone weights, wood weights, felt weights, rubber weights, leather weights, cloth weights, calabash weights, cloth strips, leather strips, etc. were also used for processing. During this period, due to the improvement of speed and materials, the luster was stronger, and glass light appeared during the Han Dynasty. If modern antique jade was polished with high-speed, one-way electric tools, it would leave dense, slender, and regular traces. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What is jade polishing?
The polishing of jade was the final work of jade, and the jade carving industry was used to calling it "light work". It was a delicate job. Generally, jade with a little hardness, such as Hetian jade, needed to be polished with different types of oilstones along one side. From coarse to fine, different types of oilstones had to be polished many times and evenly. From coarse to fine, at least three types of oilstones had to be used for polishing. After the oilstones were polished thoroughly, there would be no knife marks, tool marks, or scratches. Then, they would be polished with cowhide or cotton cloth wheels (cowhide strong light polishing, cloth wheel soft polishing). Jade polishing was divided into machine polishing and hand polishing. Machine polishing took a short time and cost less, but it was easy to grind away the edges and corners of the fine carving work, leaving very rough carving marks on the details and gaps. Hand polishing took a long time and was expensive, leaving very subtle carving marks on the details and gaps. This was also an important basis to distinguish between machine polishing and hand polishing. Polishing was divided into sub-light, sub-light natural light, and light. The sub-light surface has a matte effect. You need to play with the oil inside the jade. The sub-light natural light is close to nature and gives off a slight weak light. The finished product will be polished to the same level as the uncarved part. The bright surface will be polished to be as bright as a mirror. The light and reflection will be strong. You can clearly see the jade structure, but it will increase the whiteness of the white jade. The polishing process consisted of grinding, brushing, and polishing. It involved a variety of tools such as sand bars (240, 320, or 360, 1500, 2000), sandpaper (1000, 2000), cowhide (for polishing), appropriate amount of water (to be washed when grinding), towel (to protect the goods and prevent the jade from moving), sponge (to absorb water and see the degree of rubbing), iron sand plate (matte bar), table lamp (see polishing details), and so on. Different colors and types of jade required different polishing requirements. For example, bracelets, bracelets, necklaces, rings, etc. were mostly bright, and most of the pieces were dull natural light. Jade polishing has its own specific process, the surface is coated with a pasty polishing powder (Green for Chromic Oxides, orange-red for Cerium Oxides), grind the surface with a 2,000-mesh grinding wheel, repeat twice before applying a brush. Coat the diamond powder with a hard brush, and then fine work. For small places that cannot be thrown by large tools, use bamboo (bamboo chopsticks for large places, bamboo toothpicks for small places) to dip in diamond powder and grind. Then use hard skin to polish, and then use an ultrasonic machine to clean. For places that cannot be cleaned, use alcohol to wipe, and then wax (wash off with boiling water and blow dry). Jade carving and polishing included rough grinding (using 1000 - 2000 mesh emery tools to polish it), fine grinding (using 1600 - 1800 mesh emery to polish it until it was shiny), brightening (using half-life cowhide tools dipped in polishing powder to repeatedly rub it to make it shiny), waxing (waterproof, anti-dirt pollution) and other processes. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Jade Polishing and Edging
The polishing and edging of jade ware was an important step in the processing of jade ware. In terms of polishing, it could be divided into machine polishing and manual polishing. Machine polishing had high efficiency and low cost, but it was easy to flatten the edges and corners of the details of the work, causing the work to lose its three-dimensional sense and tension, and there might be rough carving marks left in the details and gaps. Although manual polishing took a long time and cost a lot, it could deal with the details carefully, preserving the details of the work to the greatest extent without leaving any carving marks. From the classification of polishing effects, there were roughly sub-light, sub-light natural light, and bright light. For the river grinding jade, the polishing process included three steps: polishing, brushing, and polishing. It would be repeatedly polished with different grit sizes of oilstones (sand strips, sandpaper), and then repeatedly rubbed with cowhide or cloth wheels, polishing wax, etc., and modern hand polishing would also be done with the help of machines. In the general steps of polishing jade, it includes grinding (removing the rough), that is, grinding the surface of the semi-finished jade carving with a rubber roller to make it more delicate and flat;(such as felt, leather, cotton cloth, wood, gourd shell), rubbing and rotating the surface of the jade slowly to obtain a smooth and clean surface; cleaning and polishing the jade; waxing, rubbing the wax on the hot jade, and wiping the surface after cooling to make it crystal bright. The grinding and other operations were closely related to the grinding tools. The traditional grinding tools were shellac, cowhide, emery, oilstone, etc. In modern times, there were new tools such as emery sandblasting machines and ultrasonic cleaners. The polisher could use his skills to decorate and embellish the work, such as flattening the bottom plate, straightening out the heel, improving the oiliness, straightening out the lines, slightly modifying the appearance, covering the internal structure of the raw materials, and emphasizing the artistic conception of the work. Different polishing methods and polishing operations will make the jade show different effects, such as natural light.(It is mostly used for the handle of Xinjiang Hetian jade seed material. The surface is soft and natural without reflection), soft light (after the machine is combined with a little polishing powder, the speed and hand strength cannot be too big, the surface is soft and shiny, and it is mostly used for Xinjiang Hetian jade), high light (combined with polishing powder or diamond powder, the machine speed is faster, the brightness is brighter, and there is a "beauty" effect. It is often used for the surface treatment of Russian materials, Qinghai materials or low-grade seed materials). When evaluating the quality of the jade carving, it could be judged from the smoothness of the bottom plate (even if it was not polished, it could reflect the matte effect and no tool marks), the smooth lines (round, consistent thickness, natural transition), and the cleanliness of the feet (the blocks, lines, and surfaces were handled cleanly, and the connection points were clean). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Yangzhou Jade Polishing
The polishing of Yangzhou jade ware was an important part of the jade ware production process. The polishing process had a history of thousands of years. In the jade industry of Yangzhou, the polishing methods could be divided into machine polishing and manual polishing. Machine polishing took less time and cost less, but it could flatten the edges and corners of the details of the work, causing it to lose its three-dimensional sense and tension, and the details and gaps were easy to leave rough carving marks. Although manual polishing took a long time and cost a lot, it could deal with the details very well and retain the details of the work to the greatest extent, so that it was fine and perfect without carving marks. The effects could be roughly divided into sub-light, sub-light natural light, and light. The corresponding effects would be selected according to different materials. Yangzhou also had some organizations that specialized in jade-related business. Their business covered fine processing technology such as jade cutting, polishing, and polishing. These organizations had professional teams that used advanced equipment and technology to carry out jade processing work, including polishing. They also had professional evaluation, appraisal, restoration, and other services. The scope of services covered Yangzhou and the surrounding areas. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What is the method of hand-carving, polishing, and polishing jade?
The method of hand-carving, polishing, and polishing jade articles was as follows: - [Carving: Jade is hard, but as long as you have diamond or man-made diamond tools and speed, you can carve it as you wish.] - ** Polishing **: - First, according to the thickness of the work, choose No. 240, No. 280, No. 320 oilstones for rough grinding. Hold the jade in your left hand and place it on the side of the table to adjust its position. - Then, he used a fine oilstone to grind (remove the silk) to further flatten the fine marks on the surface. - Different materials were polished according to their own texture, throwing out different luster. When polishing, use 600# - 1200#polishing sandpaper, first use electric tools to install diamond drill bits to decorate the jade piece, then use diamond miscellaneous files to carefully repair it; then use round sandpaper (made of coarse sand and fine sand) to carry out large-scale grinding, then use round cloth wheel to apply polishing paste for large-scale polishing, then use felt grinding head to apply polishing paste for detailed polishing, or use rubber grinding head to directly polish; Finally, use 1200 sandpaper to do manual polishing, and then use diamond powder to polish. - For jade with a bit of hardness, such as Hetian jade, different types of oilstones should be used to polish it a little along one side. From coarse to fine, different types of oilstones should be ground many times and evenly. From coarse to fine, at least three types of oilstones should be used to polish it. After the oilstones are polished, there should be no knife marks, tool marks, or scratches. Then, the machine should use cowhide or cotton cloth wheels to polish it (cowhide throws strong light, cloth wheel throws soft light). - In the aspect of manual polishing of ancient jade, the Neoliths mainly used manual polishing, which was done by grinding stones with water and grinding fine sand. After the Shang and Zhou Dynasties, the grinding machine was widely used to install grinding and polishing tools of different materials for processing. In addition to the ancient method, stone, wood, felt, rubber, leather, cloth, gourd, cloth, leather, etc. were also used for processing. - The hand-polishing process of the river grinding jade was divided into three steps: polishing, brushing, and polishing. It would use different grit sizes of oilstones (sand strips, sandpaper) to repeatedly polish, and then use cowhide or cloth wheels, polishing wax, etc. to repeatedly rub and polish. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Water Stool for Polishing Jade
The water bench was a simple equipment used to make jade in ancient times. It was the first process of processing jade in the workshop. It was constructed as a rectangular wooden shelf with a horizontal and vertical horizontal horizontal rod installed on it. A water trough was installed under the horizontal rod, and a wooden pole was inserted beside it to hang a bucket for cooling when grinding jade. There was a round hole at the front end of the horizontal rod, and the handle was glued to it with thermoplastic shelac. The thickness of the rear end of the horizontal rod changed, and the leather strip was wound around two or three times, and both ends were connected to the pedal. When working, the person would step on the pedal to drive the horizontal rod to rotate, which in turn would drive the chisel to rotate. The jade worker would hold the jade material with both hands and grind it at the lower end of the chisel. The water stool used a round steel knife to install wheels, pulled by a rope, and rotated by the foot pedal to open the jade. Because opening the jade required sand and water, it was called a water stool. It has thallions such as punching thallions, grinding thallions, chopping thallions, rolling thallions, etc. The punching thallions are used to cut out the shape of objects, the grinding thallions grind the rough edges and corners of objects, and the chopping thallions are used to cut open jade or cut off large edges and corners. The water stool's rotation speed was not fast and the adjustment range was limited. The rotation method was to rotate back and forth, and the grinding of the chisel on the jade was also to swing back and forth, which formed a unique craftsmanship feature. Experienced people in the modern world could distinguish whether the jade was made with a water stool or an electric jade-cutting machine according to the different marks, thus distinguishing between new imitation jade and ancient jade. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
