How to polish jade and what tools are needed for jade polishing

There are two ways to polish jade: mechanical polishing and hand polishing. Mechanical polishing is done by using a vibrating machine with emery and polishing powder.

The operation method is simple, but it is not suitable for particularly fine polishing. There are many equipment used for manual polishing, and the jade velvet needs to be polished according to the specific situation. It is usually sanded with a coarse corundum bar first, and then sanded with a thinner abrasive belt, which is a highly technical and laborious work.

4. Waxing, that is, rubbing the paraffin wax on the hot jade piece, and wiping the surface with a cloth after cooling, so that the surface of the jade piece has crystal brightness.

5. There are two kinds of jade polishing: "hard bright" and "glue bright". The "hard" light has high brightness and strong flashes; The brightness of the "glue bright" is low and weak. From the point of view of technology, "glue bright" is one less process than "hard bright", which is used when making antique jade.

There are professional tools for polishing jade rough. If you only have a small piece, you can sand it with water sandpaper according to the size of the water sandpaper.

1. Prepare a grinder similar to a small electric drill and a disc polisher.

2. Prepare a corresponding set of diamond drill bits.

3. Prepare a corresponding set of felt grinding head, rubber grinding head and polishing paste.

4. Prepare a corresponding set of round sandpaper and round cloth wheels.

5. Prepare a set of diamond assorted files.

6. Prepare some 600 pieces of polishing sandpaper for manual polishing.

The jade grinding machine is a very common hand-held grinding tool for jade carving, which is generally driven by electric power, and is divided into brushed and brushless motors as the driving source.

Extended information: Because the texture of jade is very hard, the speed of the jade grinding machine must be more than 30,000 rpm, and the power is more than 65w.

The high-quality machine has smooth speed, soft sound, low temperature, with dust collection function, speed display window for convenient speed selection, and preferably also has speed cruise control, so that it is very easy to control and select the speed when working, which greatly reduces the work intensity and.

Because a lot of dust will be produced during grinding, dust will seriously affect human health, it is recommended to choose JSDA's JD9500 grinding machine with dust suction function, the dust in the work will be pumped away at any time, effectively protecting the health of the operator.

1. Paste, coat the surface of the carved jadeite with a layer of paste-like polishing powder, and the green one is oxidized.

The chrome orange-red one is cerium oxide.

2. Push and grind, grind the surface with a 2,000-mesh grinding wheel.

3. Repeat the first two steps, generally repeating twice.

4. Put on the brush, apply the diamond powder to the surface of the jadeite and then use a stiff brush to throw.

5. Finework, start grinding in small places where large tools can't be thrown. Use bamboo, dip in diamond powder, use bamboo chopsticks for larger ones, and use bamboo toothpicks for small places.

6. Fine polishing, the jadeite is coated with diamond powder and then polished with hard skin. Most of the domestic cowhide is used, and most of the elephant skin is used in Myanmar, and the jadeite is thrown away.

Step 5: Finework, start to polish the small places that large tools can't throw with bamboo, dip in abrasive paste or diamond powder, use tungsten steel rotary file to carve the larger ones, and use alloy grinding heads in small places;

Step 6: Fine polishing, the jadeite is coated with abrasive paste or diamond powder and then polished with hard leather, most of the domestic cowhide is used, and most of Myanmar is made of elephant leather;

Step 7: Cleaning, the purpose is to clean the polishing powder remaining on the polished jadeite mainly with an ultrasonic machine, and then wipe with alcohol if the place cannot be cleaned;

Step 8: Wax to protect the surface of the finished jadeite.

Engraving directly is to use the diamond drill bit grinding and carving high-speed drill bit to grasp the mobile phone just like a pen, carving, however, the ancient method is to use the stone tool polishing first with the power tool to install the gold steel sand drill bit to modify the jade pieces, and then use the emery assorted file to repair it carefully. Large-area grinding with round sandpaper (made of coarse and fine sand). Use a round cloth wheel to apply polishing paste to a large area.

Use the felt grinding head to apply polishing paste for detailed polishing. It can also be polished directly with a rubber grinding head. Finally, it can be hand-thrown with 1200 sandpaper.

As for how the light and the matte are done?

Engraving process:

1.The carving first uses diamond powder to rub the jade flesh other than the ink line, and pastes it with a guillotine to rub out a large outline. Replace the appearance with rolling stones and rods and nails to trim the appearance until you are satisfied. This is the first step in engraving"out of the big shape.

2.Redesigned.

The excess waste jade is ground away, the cracks are removed, and the large shape is basically determined, because the ink line drawn during the design during the engraving process is worn off, and the jade needs to be re-examined and redesigned.

3.Re-engraving.

Carving, painting, carving and painting, the work is more three-dimensional in the continuous carving.

4.Carved.

Adjust the large size, determine the details, at this time, you should concentrate on correcting the details while living smoothly, and ponder until there is no extra jade meat, and the end of the smooth life.

My jade polishing method.

Polishing jade is an art that requires patience and skill. Ever since I started doing this, I've felt the joy and satisfaction it brings. Here's the detailed process I went through to polish and shoot jade:

Before I begin, I usually double-check the tools and materials I use to make sure they are clean, neat, and clear so as not to interfere with my next step.

Next, I will choose a place that is more spacious, airy, and has a smooth surface than Sun Bang for sanding. I also need to prepare various tools such as paper, water, sprayers, cutters, sanders, abrasive cloths, and fine sandpaper to clean and polish the jade.

Cutting the jade Before I start polishing, I need to cut the jade to the desired size. Be sure to wear gloves and glasses when doing this step. At the same time, the cut should be made along the specified line with a cutting machine, ensuring that the edges are smooth, and finally the desired size should be fixed.

Coarsely Ground Jade Once the cut is complete, I can use a sander to coarsely grind the jade. First, I use a grinding wheel with large grains to smooth the jade. This step effectively removes uneven parts of the surface and makes the jade smoother.

After the rough grinding is complete, I will check the flatness of the jade again to determine if I should proceed with the next step of grinding and sanding.

Grinding jade Next, I will use a finer grinding wheel for grinding. This step is critical and requires a lot of patience. I will keep grinding the jade until the surface is very smooth and beautiful.

Whenever I change the granularity of the grinding wheel, I use a sprayer to gently spray some water on the surface of the jade to keep the surface moist. This helps the abrasive cloth to disperse the abrasive better, making the stone smoother.

Fine grinding of jade After I finish grinding, I use fine sandpaper for fine grinding. This step is to further enhance the shine and smoothness of the jade. I usually place fine sandpaper on a plastic stick and rub it back and forth on the surface until I achieve the best results.

Polishing jade The final step is polishing. I usually use a polishing machine to polish the surface of the jade to make it smoother, more beautiful, and even able to reflect light.

After polishing, I wipe the surface of the jade with a clean cloth and do a final inspection to make sure it doesn't have any blemishes or irregularities.

Conclusion Polishing jade is an art and skill that requires practice, patience, and concentration. However, when you see the final product, it will give you an extreme sense of satisfaction and accomplishment. I hope this article can be of some help and reference to those who want to try polishing jade.
