What is used to polish jadeite?

Question 1: What tools do you need for jadeite polishing?

Experience 1:

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

2. Prepare a set of corresponding diamond bit.

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

4. Prepare a set of circular sandpaper and circular cloth wheel.

5. Prepare a set of assorted diamond files.

6. Prepare some 600 #- 1200 # polishing sandpaper for manual polishing.

The process is:

1. First, use electric tools to install a diamond drill to decorate jade, and then use a diamond assorted file to repair it carefully.

2. Use circular sandpaper (made of coarse sand and fine sand) to polish a large area.

3. Wipe the polishing paste on the circular cloth wheel for large-area polishing.

4. Polishing the details with a felt grinding head with polishing paste.

5. Rubber grinding head can also be used for direct polishing.

6. Finally, it can be polished by hand with 1200 sandpaper.

Experience 2:

Step 1: Paste: Apply a layer of paste polishing powder on the carved jade surface, with chromium oxide in green and cerium oxide in orange.

Step 2: Push grinding, grinding the surface with a 2000-mesh grinding wheel.

Step 3: Repeat the first two steps, usually twice.

Step 4: Brush, coating diamond powder on the jade surface, and then throwing it out with a hard brush.

Step 5: Work carefully and start polishing small places where you can't throw big tools. Use bamboo, dip it in diamond powder, use bamboo chopsticks for the bigger ones and bamboo toothpicks for the smaller ones.

Step 6: Fine polishing: coat jadeite with diamond powder and polish it with hard skin. Cowhide is mostly used in China, and elephant skin is mostly used in Myanmar. This jade has been polished, but there are still a few finishing touches to be done.

Step 7: Cleaning, the purpose is to clean the residual polishing powder on the polished jade. It is mainly cleaned by ultrasonic machine, and the parts that cannot be cleaned are wiped with alcohol.

Step 8: Waxing, which protects the surface of the finished jadeite, can be washed off with boiling water and then dried. A beautiful jade will meet you like this.

Experience 3:

The carving and polishing process of jadeite has high hardness, but as long as there are diamond or synthetic diamond tools and speed, you can carve at will. It's easy to polish until it shines. There are three basic processes.

1, rough grinding-Tools of various shapes made of emery (1000-2000 mesh) are carefully polished and smooth.

2. Fine grinding-Use the above (1600- 1800 mesh) emery to make it smooth and shiny.

3. Glazing: Immerse the tools made of half cowhide in polishing powder (diamond powder of 2800-3000 mesh) and rub repeatedly to make the jadeite products bright inside and outside.

4. Waxing-Waxing is to prevent water and dirt pollution.

Experience 4: polishing jadeite by hand without machine.

1, prepare the following:

A spoonful; A section of waste cowhide about 8 cm long; 600#, 1500# water sandpaper; Jade polishing powder.

2. Use 600# water sandpaper and 1500# water sandpaper in turn to polish jade articles until there are no grinding marks.

3. Cut an opening at one end of the belt to make it herringbone.

4. Put a proper amount of polishing powder into the ladle and add a small amount of water to make it paste.

5. Apply the polishing powder paste to the open end of the belt section, hold the other end of the belt section by hand, apply the polishing powder to the jade, and rub it repeatedly until the jade shines. (My experience needs 1- 1.5 hours)

6. During polishing, the polishing powder should be kept in paste. If it is too dry, you can add a proper amount of water.

Question 2: The simplest manual jadeite polishing can't produce any effect. The process of jadeite polishing is actually a fine grinding operation. Emerald polishing involves polishing agents and polishing tools. That is to say, the polishing agent is mixed with some liquids (such as water and sewing oil) in a certain proportion, so that it adheres to the polishing tool and rubs against the workpiece. If the jade polishing operation method is proper, the jade piece can present a beautiful appearance.

The process of jade polishing is realized by attaching polishing agent to polishing tool and rubbing with jade. Ordinary polishing tools are divided into two categories. A jade article used for polishing a convex surface, a spherical surface and a conformal surface. Usually, polishing discs or polishing discs are made of felt, leather and woolen cloth, which are called floppy disks. The other type is used to polish jade articles with flat surfaces. Usually, polishing discs are made of hard materials with strong compression resistance, such as metal, plastic and wood. Polishing discs made of metal are usually called hard disks, while polishing discs made of wood, plastic or even asphalt are called medium-sized hard disks.

In addition, because most jadeite processing is curved or curved, soft jadeite polishing tools are often used.

The effect of pure manual polishing of jadeite is not very good. It is best to use some tools for detailed processing, and the products will look good.

Question 3: How to polish jadeite This polishing knowledge is only for personal enthusiasts, and it is only a personal understanding. If there are any shortcomings, please give us your suggestions:

One. Polishing is the last process of jadeite, and the jade carving industry is usually called "light industry".

Two. Jade polishing can be divided into machine polishing and manual polishing.

Machine throwing: short time and low cost. Disadvantages: it is easy to grind off the fine carving edges and corners, and there are very rough carving marks in the details and gaps.

Hand throwing: long cycle and expensive. Disadvantages: after a long time, there are subtle carving marks in details and gaps (this is also an important basis for distinguishing machine throwing from hand throwing).

Three. Polishing is divided into: sub-light, sub-light natural light and bright light.

Matte: There is some matte effect on the surface, so it is necessary to gradually dish out the oil inside the jade. This has only appeared in the past two years, and jade is very expressive.

Sub-light natural light: personal understanding is close to nature and emits slightly weak light; The finished product after grinding and engraving is consistent with the non-engraving part.

Bright light: the surface is polished like a mirror, eye-catching, bright and reflective; Will increase the whiteness of white jade.

Four. Polishing process steps: grinding → brushing → polishing.

Five. Polishing tool:

Sand bar: 240 320(360),1500,2000.

Sandpaper: 1000 2000

Cowhide: used for polishing.

Proper amount of water: used for cleaning when grinding objects.

Towel: the first protection; Second, prevent jade from moving.

Sponge: used to absorb water, depending on the degree of scrubbing.

Iron sand board: used for grinding long strips.

Desk lamp: It is to see the polishing details more clearly and carefully.

………………

Six. For babies with highlights, I want sub-light or natural light. Just use 1500 sand bar to polish it off, then use 2000 sand bar to polish it carefully, and finally use cowhide to polish and rub the baby.

Seven. For hetian jade, nothing is absolute. Different colors and different types need different polishing.

Bracelets, bracelets, necklaces, rings, etc. Most of them are bright, and most of the handles are sub-light natural light. ............

Finally, polishing requires great perseverance, patience and care, and it is also a good method of self-cultivation.

Treasure thrown out:

The first step is to grind the roughest sand strip into an inclined plane on the iron sand plate. Then first use the roughest sand bar to polish;

I just polished it with the roughest sand bar, and the knife marks left by the master's carving have been preliminarily polished and leveled:

I worked overtime last night to finish more than half of the project;

Step 2: Use 320(360) coarse sand for the second serious treatment; After treatment, the carved knife marks have disappeared, leaving only the grinding marks of sand strips;

Just now, the "friend" said that the steps of 240 are very important, which is true, because a finished product "wool product" can directly see the owner's carving level and carefulness, and also determine the aesthetic degree of (240 sand strips) polished baby. Let's get down to business: the third and fourth steps are equally important, and they determine the key to success:

When polishing with sand strips of 1500 and 2000, attention must be paid to the degree of force. In the first and second steps, we can use a little force to remove tool marks. Then, the third and fourth steps should be lightly rubbed:

Step 3: After completion, you can basically see whether the baby is damaged:

Step 4: Use 2000 sand strips and sandpaper, gently knead, don't use force, if the force is too large, it is easy to leave traces of sand strips for the baby; It's almost finished, and polishing is very tiring physical work;

The fifth step: cowhide, rub the baby hard, basically even if the task is completed, the details need to be strengthened.

Off-topic: This kind of cowhide is included in leather shoes. I modified it to make it smoother:

Eight. How to cast sub-light natural light into strong light: 1500.2000 Use sand strips and cowhide.

Step 1: Rub all the highlights of the baby evenly with the sand bar of 1500:

Step 2: use a 2000 sand stick to beat it evenly and finely, and brush it with a toothbrush;

Step 3: If the cowhide is cowhide more than once, the matte natural light will come out: ... "";

Question 4: What should I pay attention to when polishing jadeite? It is best to choose mature professionals and tools to ensure that your skills pass.

Question 5: How to polish and polish jadeite;

The first step: plastering, that is, coating a layer of paste grinding paste on the carved jade surface, wherein the green one is chromium oxide, and the orange one is cerium oxide;

Step 2: Push grinding, grinding the surface with a grinding wheel;

Step 3: Repeat the first two steps, usually twice;

Step 4: Brush, that is, apply grinding paste or diamond powder on the surface of jadeite, and then polish it with bristle brush or bristle grinding head;

Step 5: Work carefully and start polishing small places where you can't throw big tools. Use bamboo, dip grinding paste or diamond powder, use tungsten steel rotary file to carve larger parts, and use alloy grinding head for small parts;

Step 6: Fine polishing: the jadeite is coated with grinding paste or diamond powder, and then polished with hard skin. Cowhide is mostly used in China, and elephant skin is mostly used in Myanmar.

Step 7: Cleaning, the purpose is to clean the residual polishing powder on the polished jade. It is mainly cleaned by ultrasonic machine, and the parts that cannot be cleaned are wiped with alcohol.

Step 8: Waxing to protect the surface of jadeite products.

Question 6: The hand grinding method of jadeite generally has a high hardness, and of course, it is also like jadeite with low hardness nails, which is not much lower than a metal knife. Generally, manual grinding should be done slowly with tools made of grinding wheels. If there is a diamond grinding wheel, it will be much faster.

Hand grinding should have: as long as the kung fu is deep, the iron bar is ground into a needle, and perseverance is enough. If you are really interested, you can buy a set of electric grinding wheel tools to polish.

Question 7: What sandpaper should be used to polish jadeite? The first is 400 granularity 600 1000 1200, and the last is 7000 granularity.
