Analyze the maintenance problems of jade and hetian jade

October 29, 2020

The year is close, and many people like to buy some new year's goods to celebrate the new year. China is also a country that advocating jade from ancient times. There are ancient rituals such as "Junzi Bide and Jade" and "Junzi have no reason to go to the body". Therefore, buying a piece of jade jewelry at the end of the year has become the first choice for many consumers to treat themselves. So how should jade be worn? Is the jade bracelet "floating flower" become "full of green" credible? Is it desirable to play Hetian jade "蹭人油"? With these questions, China Cultural Relics Network interviewed Mr. Xu Botao, the gold medal pawn of the Baoruitong pawnshop's civilian product management center, and asked him to talk about the maintenance of jade and Hetian jade.

Jade is especially afraid of acid and alkali

Jade is very sensitive to pH, even weak acid and weak base have a certain degree of influence on jade. For example, if the A jade bracelet does not pay attention to maintenance in daily life, especially when washing dishes, cooking, and bathing, then after two or three years, for spectrum identification, there will be "different "Light" appears, "special light" usually means "not A goods." Although it is not necessary for the entire bracelet to have a different light, there will be some changes in this part. Therefore, care should be taken to avoid exposure to acidic, alkaline chemicals.

The history of jade in China is not far away. There are records of physical evidence and historical records, which began to appear in the Ming Dynasty. In the middle of the Qing Dynasty, jade was introduced in the court, so it began to flourish in the late Qing Dynasty and reached its peak. . The jadeite unearthed from the Ming Dynasty to the end of the Qing Dynasty generally does not use spectral identification. Because the underground acid-base environment is complex, the jadeite has been buried for a long time, and the acid and alkali substances have invaded the jade surface and even penetrated into the jadeite to make it physically. The chemical properties change, so the spectral identification of the unearthed jade often fails to achieve the desired effect.

Soaking water can improve the quality of jade

During the wearing of jade, always wash with pure water and wipe with a soft cloth. It is especially suitable for jadeites of the "ice" or "ice bean" grade. In order to make the jade color more beautiful, it can be soaked in pure water. Because the molecular structure of these two jadeites is not very dense, there is a gap in the middle. By soaking, water molecules can slowly penetrate into these gaps, making the jade head better, the color more vivid, and the quality better.

However, there are several points that need to be reminded to consumers. First, this quality improvement cannot be maintained for a long time. When leaving the water for a while, the jade will return to its original state. Therefore, if you want the quality of jade to remain stable, you need to constantly Soak. Second, this quality improvement is not unlimited. There are often merchants saying, “A star-shaped green bracelet is worn over decades and will eventually turn into a green bracelet.” This is just a promotional tool for merchants. By playing with the disc, the color of the jade will spread to a certain extent, but it will never change from "floating flowers" to "full green", otherwise the merchants will not be willing to sell the "floating flowers" of jade. For the relatively dense "glass type" jade, the effect of water soaking is not great, even if soaked, the effect is not so obvious.

Hetian jade "蹭人油" is not advisable

Contrary to jade, Hetian jade is close in texture and requires “running”, which consumers can wear for a long time. The oil and sweat secreted by the human body can nourish Hetian jade, making it more "oily" and more moist. If Hetian jade is soaked in water for a long time, it will lose its oiliness and its quality will be reduced. As for the popular saying - "small oil", which is to deliberately rub the oil on the face to Hetian jade, Xu Botao believes that this method is not desirable. First of all, it is not hygienic. Secondly, "temporary cuddling" can only make Hetian jade "small layer of oil slick, and did not eat jade inside." Xu Potao said, "only slowly and qualityally absorbed, can we let Hetian Yuyue wears more and more."

Scrubs are the sanitary clothing worn by surgeonsnursesphysicians and other workers involved in patient care in hospitals. Originally designed for use by surgeons and other operating room personnel, who would put them on when sterilizing themselves, or "scrubbing in", before surgery, they are now worn by many hospital personnel. Their use has been extended outside hospitals as well, to work environments where clothing may come into contact with infectious agents (veterinariansmidwives, etc.). Scrubs are designed to be simple (with minimal places for contaminants to hide), easy to launder, and cheap to replace if damaged or stained irreparably. In the United Kingdom, scrubs are sometimes known as theatre blues.
