Question 5: How to clean the old jade bracelet with serious pollution and send it to a special company?

Six correct ways to maintain jade.

First, avoid colliding with hard objects.

Although jade has high hardness, it is easy to crack after being hit. Sometimes, although cracks can't be seen by naked eyes, the molecular structure inside jadeite has been destroyed and dark cracks have appeared, which greatly damages its perfection and economic value.

Second, avoid dust as much as possible.

If there is dust on the jade surface, clean it with a soft brush; If dirt or oil stains are attached to the jade surface, it should be washed with mild soapy water first, and then washed with clear water. Do not use chemical degreasers. If the jade is exquisitely carved and not dusted for a long time, please clean and maintain it in professional factories and companies that produce jade.

Third, try to avoid contact with perfume.

Seed jade and ancient jade have a transformation process, which needs the help of human body temperature. Sweat will make them more transparent, so seed jade and ancient jade can be exposed to sweat more, because human sweat contains salt, volatile fatty acids and urea, which can make the surfaces of seed jade and ancient jade thoroughly remould themselves and become more and more moist. However, if Xinyu is exposed to too much sweat, it will damage the outer layer and affect its original brightness, especially for objects carved with suet white jade, avoid sweat and oil stains. Many people think that the more Hetian jade touches the human body, the better. Actually, this is a misunderstanding. If you sweat too much, sheep fat white jade will easily turn pale yellow and no longer be as pure white as fat.

Fourth, the Yuhuan border of Hetian jade should maintain a suitable temperature.

Jade should be kept by a certain humidity. Without temperature and brightness, it will lose its artistic value and economic value.

Hetian jade jewelry inlaid with diamonds, rubies, emeralds and other gems can be wiped with a clean white cloth to wipe off oil, dust, impurities, moisture or sweat, which is helpful to maintain and maintain the original quality.

Six, the pendant should be put away when not in use.

It is best to put it in a jewelry bag or jewelry box to avoid scratching or damage. If it is high-grade Hetian jade jewelry, don't put it on the counter to avoid dust and dirt, which will affect transparency.

Old methods of modern ancient jade

Modern antique jade is mainly made of jade books. Because the jade patterns in the book have great errors in angle and color in the process of photography and plate making, and the patterns are only positive and rarely negative, so they can only be copied according to the patterns. Now in the books about jade, some ancient jade are fakes, which are made by manufacturers and turned into imitations.

Suzhou and Yangzhou have been the centers of jade production since ancient times, with a long history of jade-making technology and tradition. There are a group of jade experts in these two places, who have received strict training in the jade carving factory before and went to the arts and crafts school for further study, and have a certain understanding of traditional crafts. After leaving their jobs, these people are still engaged in jade processing, and also help those who manage jade to repair it. Therefore, they know more about the shapes of ancient jade articles and have more contacts. The antique pieces made by them are deliberately polished, ashed and colored by Bengbu people in Anhui Province, which are very realistic and will be fooled if they are not careful.

Characteristics of old-fashioned technology

Before wearing, it is usually polished with oilstone, fine sandpaper or diamond, and then polished. It is useful to use cerium dioxide to polish utensils on cloth wheels, and there is another kind of grinding with emery, talcum powder or fine sawdust in a special drum, which is called rolling grinding.

Antique technology and materials of jade articles

The distinction between ancient jade and handed down ancient jade is based on unearthed ancient jade and handed down ancient jade. The difference between the two is reflected in the color of Qin dynasty, and the method of making old jade is basically the same but slightly different.

If some jade materials are impure in texture, there are stones, spots, colors, cracks, softness and hardness. Understanding jade materials is the first condition for making old jade. What kind of old jade is suitable for making, just like what kind of jade.

The method of imitating old jade is nothing more than smoking, roasting, burning, boiling, frying, eroding and coloring. The equipment used is kiln, stove, microwave oven, coal stove, electric stove and wood stove, and the auxiliary materials used are dried apricots, dried plums, turmeric, dragon's blood, toilet paper, castor oil, sawdust, shoe polish, asphalt, brown sugar, spices and carrion.

Smoked old

The residual smoke oil impurities in cracks and tool rolling cracks and the pale yellow surface make the imitation jade have a natural and old effect.

Bake old

Will imitate the old cleaning to eliminate oil, oil can be boiled in alkali, pruned water, acid and alkali corrosion and other methods The degreased old jade is coated with organic or inorganic coloring dyes or pigments, and heated and baked in an electric furnace, a coal stove or an oven to make the color baked into jade. This kind of painting is mainly made of various shades, such as shoe polish and asphalt for black, brown sugar for red, turmeric and dragon blood for yellow. The acceptable temperature of each kind of jade is different, so we should also pay attention to it. Jade is easy to crack when roasted with fire, but it can be roasted to chicken bone white at high temperature.

burn-up

Barbecue with an open flame is called burning old. The difference between baking and baking is that the baking temperature is high. The old jade burned at high temperature is immediately put into the dye solution for coloring. The color effect of Qin varies with dyes and jade. Under normal circumstances, the burnt and deteriorated parts taste dark. The undamaged part is lighter in color. Because the temperature difference of old jade changes rapidly, tiny cracks are produced on the jade, which can be made into cow hair pattern old jade.

Fried color

This method is just the opposite of burning old jade, that is, heating all kinds of oil until it smokes, immediately putting the imitation old jade frozen at room temperature or in the refrigerator into hot oil, and the oil color is smooth ...
