How to polish jade, how to polish jade

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.

Hand polishing methods of jade:1How to polish jade?

Grinding is also called "roughening", that is, using "glue grinding" to polish the surface of the semi-finished jade carving to make it more delicate and smooth. Here are some simple preparations before polishing. 2.

How to polish jadeite, polish with a special polishing powder. The polishing agent generally uses red powder (iron oxide powder), green powder (chromium oxide powder), and natural diamond powder. Mix the polish with an appropriate amount of water and oil, apply it to a weight wheel made of soft materials such as felt, leather, cotton, wood, gourd shell, etc., and then slowly rub it on the jade surface, and then rotate it for a while to obtain a smooth, clean, and shiny jade surface.

The beauty of the jade material and the beauty of the jade craftsmanship can be fully reflected.

1. First of all, coat the surface of the carved jade with a layer of paste-like polishing powder.

2. Then grind with a grinding wheel.

3. Repeat the above two steps, about two or three times.

4. Then apply the diamond powder to the surface of the jade and polish it with a stiff brush.

5. For relatively small places, you can use bamboo skewers dipped in diamond powder to polish, and finally fine polishing, generally using cowhide.

6. The last step is to clean, use an ultrasonic cleaner to clean, and some places can not be cleaned with alcohol to wipe.

Here's how to polish jade:

1.Prepare polishing powder, a small grinder, or a hand grinding tool to gently sand the surface of the jade. For more delicate jade, manual fine polishing is more suitable.

2.Use polishing powder and a small sander (or manually use fine sandpaper) to polish the jade.

3.For jade that has already been processed, animal leather can be used for polishing. The leather is constantly rubbed wildly against the jade, and the effect can be seen after a long time.

4.The polishing powder can be poured into water, stirred into a paste and spread on the surface of the jade, and then polished with leather. Leather can be cut into long strips for easier sanding.

Please note that going to the beach, or under the air conditioner, is likely to cause the jade to break. In addition, jade should avoid collision with hard objects. Hope this information helps.

Before polishing the jade, the surface of the semi-finished jade should be polished more delicately and smoothly with a rubber mill, and then the polishing powder, water, and oil juice should be prepared, and then applied to soft leather or cotton cloth, and then used to wipe the surface of the jade until it is smooth and oily. Finally, wax the polished jade and wipe the surface of the jade with a cloth.

1. Soaking. When you have started to choose the stone that needs to be polished, put the stone in a suitable container, cover it completely with water, and soak it for two or three days. The reason for this is to allow the floating soil on the stone to fully dissolve and loosen the dirt attached to the surface.

2. Brushing. After the stone is soaked, scrub the surface and crevices of the stone with a brush (you can choose a steel brush for harder stones, and a nylon brush is best for softer stones), and brush the stone with water.

3. Grinding. After the stone has been soaked and brushed, it is ready to be sanded. In this step, you must be patient, choose the corresponding grinding head according to the thickness of the stone texture, and carefully polish it in the order of coarse first and then fine.

The simple ways to polish jade are:

Hand tossed

Use 600-1200mm polishing sandpaper, first use a power tool to install a diamond drill bit to decorate the jade parts, and then use a diamond 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 handmade with 1200 sandpaper, and then polished with diamond powder.

Machine thrown

A small jewelry jade cylinder polishing machine. Buy some of our flying abrasives of corundum 320-8000mm, there are rough to fine polishing. Then buy triangle bead polishing grains, cold light powder, grinding polishing powder and throw it in the polishing machine for a period of time to achieve the mirror effect.

Jadeite polishing

The surface is coated with a layer of paste-like polishing powder, green is chromium oxide, orange is cerium oxide. Use a 2,000-mesh grinding wheel to grind the surface, repeat the first two steps, generally repeat the second time after the brush, paint the diamond powder on the surface of the jadeite and then use a hard brush to throw, fine, and begin to throw the big tool into a small place to polish, with bamboo, dipped in diamond powder.

Bamboo chopsticks are used in larger places, bamboo toothpicks are used in small places, and the jadeite is coated with diamond powder and then polished with hard skin, and then cleaned with an ultrasonic machine.

Then wax to protect the surface of the finished jadeite, which can be washed off with boiling water and then blown dry, and a beautiful jadeite is made.
