Jade in the instrument before are not carved with the same nature jade, so in essence, the protection of jade is the protection of natural minerals and rocks. By the Knockoff Van Cleef Butterfly Earrings China Geological Museum senior engineer Miss Yao Yajuan to explore and research, in the protection of jade in this area summed up a lot of valuable results.

From the prevention of jade physical properties of the cracks disintegration and chemical properties of the corrosion, pollution, etc., the protection of jade collections are the following three methods:

First, the penetration protection law

Refers to the jade along the pores, cracks and other in-depth protective liquid to its reinforcement, so that it is not easy to crack or disintegration of a protection method. This method is suitable for the protection of those who are more loose or less dense, more cracks in the external factors under the effect of easy to split or disintegrate the jade. The protective solution used in this method is mainly organic reagents, such as acrylic emulsion, methyl methacrylate and so on. From the appearance of this protection method to ensure that the characteristics of the collection, that is basically no distortion, and thus effective.

Second, the film Knockoff Van Cleef Butterfly Necklace protection method

Refers to the surface of the jade coated with a layer of polymer organic compounds in the film, so that isolated from the air, and thus achieve a purpose of protection. This method can avoid the collection of jade suffered oxidation, deliquescence. The polymer compound used must be colorless and transparent, with the best performance of methacrylate polymer, acrylic varnish No. 6, silicone rubber, polyvinyl alcohol and butyraldehyde. Film protection method has the advantage of simple and easy, and jade can enhance the brightness of its surface, from the appearance of jade basically no distortion. But the effect of relatively infiltration method to be worse, and the film should be replaced regularly to prevent aging.

Third, embedded protection law

The jade embedded in a solid material in the transparent material, so that isolated from the air, so as to achieve the purpose of protection. This method prevents the protected jade from being oxidized and reduced by ultraviolet radiation. The embedding material used in this method is a methyl methacrylate polymer, and an ultraviolet absorber is added thereto. When the jade embedded in which, you can be drawn into a vacuum, plus polymerization, making it a transparent solid. The advantages of this method can be long-term effective protection of jade, and because after embedding its own color bright, transparent, beautiful appearance, durable, so itself can be used as art. But the shortcomings of this method is also more prominent, that is difficult to be buried after the jade out to reproduce the original appearance.

1. Burning silver jewelry with fire (lighter), destroying the surface of the organization. Baking time as the size of silver jewelry thickness, this process commonly known as “too much”.

2. After cooling it and then put it into the alum water to cook, boil and then remove the silver jewelry, into the cold water to a soft brush (such as: toothbrush) dipped in toothpaste or laundry Knockoff Van Cleef Butterfly Bracelet milk cleaning.

Wearing gold and silver is a lot of women’s hobbies, many people will be in the summer, go out wearing a nice skirt, and wear earrings, necklaces, rings and other metal jewelry. Medical experts remind that wearing metal jewelry can increase the beauty, but from a health point of view it is not enough to take.

Summer, the body parts are easy to sweat, earrings, rings, necklaces and other metal jewelry, usually contain a certain amount of nickel, chromium and other ingredients, especially those inexpensive, poor quality synthetic metal jewelry, add ingredients more complicated. Once the body sweating, sweat and jewelry will be nickel, chromium and other metal components react, it is easy to lead contact dermatitis, etc., there erythema, blisters, itching and other symptoms. If you do not pay attention to timely picking jewelry, allergy symptoms will gradually spread to the formation of blood, edema, severe cases and even the formation Knockoff Van Cleef Butterfly Ring of ulcers, serious damage to human skin health.

In addition, these metal jewelry decoration and pattern, it is easy to contaminate and hide a lot of viruses, bacteria, become “filth”. In the hot weather conditions in summer, the bacteria will be a lot of breeding, if these metal jewelry on the body, it is easy to cause skin infections and other diseases.

There are some Hermes Collier de Chien Bracelet Replica people like to wear a lot of jewelry at the same time, often earrings, necklaces, rings, bracelets, anklets, headdress, etc. “battle”, one can not less. In fact, wearing too much jewelry will greatly increase the infiltration of harmful substances on the human body area, so that the body infected, the probability of injury increased significantly.
