What is used to polish jade?

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

Experience 1:

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

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 diamond drill to decorate jade pieces, and then use diamond assorted files to repair them carefully.

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

3. Wipe polishing paste on a 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 surface of jadeite and then throwing it with a hard brush.

Step 5: Fine work, and start polishing small places where big tools can't be thrown. Use bamboo, dip it in diamond powder, use bamboo chopsticks for larger ones, and use bamboo toothpicks for small places.

Step 6: Fine polishing: the jadeite is coated with diamond powder and polished with hard skin. Cowhide is widely used in China, and elephant skin is widely used in Myanmar. The jadeite 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, a kind of protection for the surface of the finished jade, 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 jade 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 made of emery in various shapes (1000-2000 mesh) are carefully polished to make them smooth.

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

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

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

Experience 4: don't use machines to polish jade by hand.

1, prepare the following things:

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 to polish jade articles in turn until there are no grinding marks.

3. Cut an opening at one end of the seat belt and make it into a herringbone.

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

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

6. When polishing, the polishing powder should be kept in paste. If it is too dry, you can add some water.

Question 2: The simplest manual jade polishing can't produce any effect. The process of jade polishing is actually a fine polishing operation. Jade polishing involves polishing agents and polishing tools. That is, 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 jade is polished properly, jade pieces can present beautiful appearance.

The process of jade polishing is realized by attaching polishing agent to polishing tool and rubbing 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 the polishing disc or polishing disc is made of felt, leather and woolen cloth, which is called floppy disk. The other is to polish jade with a plane. Usually, polishing discs are made of hard materials such as metal, plastic, wood and so on. Polishing discs made of metal are usually called hard disks, while polishing discs made of wood, plastic or even asphalt are called dielectric hard disks.

In addition, because jade processing is mostly curved or arc-shaped, nephrite polishing tools are often used.

The effect of pure hand grinding 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 jade This knowledge of polishing is only for personal enthusiasts and only for personal understanding. If there are any shortcomings, please give us your comments:

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

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

Machine switching: 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 frosting effect on the surface, so it is necessary to gradually pan out the oil inside the jade. It only came out 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; Polishing the carved finished product to be consistent with the non-carved 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:

Shaba: 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 rubbing.

Iron sand board: used for grinding bars.

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

………………

Six. For high-gloss babies, I want sub-light or natural light. Just polish it with 1500 sand bar, then polish it with 2000 sand bar, and finally polish and rub the baby with cowhide.

Seven. For hetian jade, nothing is absolute. Different colors and 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 way to cultivate one's morality.

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 rod 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 and finished 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 step of 240 is very important, indeed, because a finished product "wool goods" can directly see the master's carving level and meticulous degree, and also determine the aesthetic degree of (240 sand strips) polishing baby. Get to the point: the third step is as important as the fourth step, which determines the key to success;

When grinding with sand strips of 1500 and 2000, be sure to pay attention 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 if the baby is damaged:

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

Step 5: Cowhide, rub the baby hard, even if the task is basically completed, the details need to be strengthened.

Off-topic: This 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: Use 1500 sand bar to wipe all the highlights of the baby evenly:

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

Step 3: If the cowhide is cowhide for more than one time, matte natural light will come out: ... >>

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

Question 5: How to polish jade;

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, generally twice;

Step 4: Brush, that is, apply grinding paste or diamond powder on the jade surface, and then throw it out with a bristle brush or bristle grinding head;

Step 5: Fine work, and start polishing small places where big tools can't be thrown. Use bamboo, dip in grinding paste or diamond powder, carve the large ones with tungsten steel rotary files, and use alloy grinding heads for the small ones;

Step 6: Fine polishing: the jadeite is coated with grinding paste or diamond powder, and then polished with hard skin. Cowhide is widely used in China, and elephant skin is widely 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: Generally speaking, the hardness of jade by hand grinding is relatively high, and of course, like jade with low hardness nails, it is not much lower than that of metal knives. 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.

Manual grinding should have: as long as the kung fu is deep, the iron bar is ground into a needle, and perseverance will do. 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 jade? The first is 400 granularity 600 1000 1200, and the last is 7000 granularity.
