Clear water is good \x0d\ Burmese jade should also rest \x0d\ Wash Burmese jade regularly: soak in clear water for 30 minutes. If its surface becomes dirty due to long-term wear, gently scrub the jade with a small soft brush after soaking. In this way, it is difficult for corrosive substances to exist on the surface of jade for a long time to damage it, and at the same time, it can make up for the "moisture" lost by jade in high temperature in summer or when you wash mulberries. It is necessary to wash it once a month. In the hot south, take a bath every day. Be careful, if you like to take a hot bath, take off your beloved jade. You can also use shower gel for bathing at ordinary times \x0d\ In addition, you should pay attention to observe whether the hanging rope is worn and whether the inlaid ornaments are loose every time you clean it, so that you can find it in time and send it back to the store for maintenance to avoid the loss of jadeite caused by broken hanging rope and loose inlay. \x0d\ 2。 Maintenance in midsummer \x0d\ With the approach of midsummer, people sweat more, and the salts, volatile fatty acids, urea and other substances contained in human sweat will gradually erode the appearance of jadeite. Thus destroying the "brightness" and luster of jade. Therefore, it's best not to play with jade on your hands in summer. Those ornaments worn on your body close to your skin, such as bracelets and pendants, should always be washed by hand with neutral washing liquid (believe it or not, your neutral facial cleanser or shower gel is very good). If an individual sculptor has difficulties, he can brush it gently with a soft brush (all kinds of brushes are good choices) and put it in a cool place to dry (I will wipe it again directly). Remember! ! Jade jewelry should also avoid long-term contact with acids, alkalis and organic solvents, such as various cosmetics, perfumes and hairdressing agents, which will corrode its surface. \x0d\ 1。 Burmese jade is also called jadeite. Myanmar jadeite is bright and clean because of its high hardness. Moreover, good jadeite is bright and peaceful in color and has high preservation and collection value, so it is called "the king of jade". It is loved by many people who love and wear jade. Japan and New Zealand also regard jade as their "national stone". Due to the special geographical relationship that jadeite is produced in Myanmar, which is close to China, and most of the finished products are processed in China, and the special preference of China people for jadeite, western countries generally consider jadeite as China's "national jade". \x0d\ Second, the color of Burmese jadeite. Due to different regional customs, the color of Burmese jadeite is slightly different. In the jade kingdom of Myanmar, jadeite can be divided into three categories, with a grade of 12. The domestic jewelry industry divides jadeite into more than 30 grades according to its color. Generally speaking, the tones of Burmese jade can be roughly divided into the following six types. \x0d\ 1, white. Basically contains no other impurity elements \x0d\2, red. Contains the chemical element iron \ x0d \ 3, green. Chromium 〉 Cr 〉 containing more than 2% is commonly known as Cui 〉 x0d 〉 4, black. Contains more than 2% of 〈cr〉, Fe \ Fe2+\ x0d \ 5 and purple. Elements containing chromium, iron and cobalt, especially the green color in Burmese jade, can be worn regardless of status, status, age and sex, except for its bright color and excellent durability. Therefore, it conforms to the implicit, peaceful, Wen Ya and cordial character of China people. The social demand is growing day by day. Prices have also doubled or even hundredfold. At present, the price of a jade bracelet in the international market has reached 10 million yuan. Even Myanmar jadeite ornaments with slightly inferior jadeite color are expensive as long as they are genuine A goods with sufficient water head, clear technology and harmonious colors. \x0d\ III。 Quality and identification knowledge of Burmese jadeite. No matter from the mineral resources or mining capacity of Burmese jade, good jadeite is very limited, so some speculators and mercenary businessmen "take advantage of it". A large number of fake and fake goods, profit from it. Even in the emerald kingdom of Myanmar, fakes abound; Fake stones and ornaments can be seen everywhere. \x0d\ There are four kinds of Myanmar jadeite that are popular in the market at present, according to the grade of authenticity: \x0d\a goods have both natural texture and natural color. The identification method mainly focuses on the following three points: \x0d\( 1) Think twice before you act. Due to the relationship between mineral resources and mining volume and the specific conditions of large demand, there are few good Burmese jadeites on the market at present. In particular, there are few varieties with green color and bright ground color. \x0d\(2) Generally, Mabel Miao, spinach green, scarlet or violet are common varieties. \x0d\(3) Observed by naked eyes under light, the texture is fine, the color is soft, and the stone lines are obvious; Slight impact, crisp and pleasant voice; Holding it in your hand has a heavy feeling, which is obviously different from other parts of the stone. \x0d\b The jadeite with black spots, commonly known as "dirty", will be soaked in strong acid for corrosion to remove dirt and cotton to increase transparency, and then epoxy resin will be injected into the microcracks caused by strong acid corrosion with high pressure to fill the cracks. \x0d\ (1)b commodity has good initial color. If you look closely, the color will be abnormal. If you look at it under a lamp, the color transparency will be weakened. \ x0d \ (2) Within two years, goods B gradually lost their luster, were full of cracks and became ugly. This is caused by the strong acid destroying its original quality. \x0d\ (3) The density is reduced and the weight is reduced. Slight impact, low voice, lost the crisp sound of a cargo. \x0d\c The goods are completely painted by hand. \x0d\ (1) At first glance, color is not right and evil. \x0d\(2) Looking closely under the lamp, the color does not naturally exist in jadeite crystals, but is filled in the cracks of minerals, showing a network distribution of colorless roots. \x0d\ (3) When observed with Charles filter, the green color turns red or colorless. \x0d\(4) Scrubbing with strong fading spirit can remove the surface color or turn brown. \x0d\d goods, d goods posing as jade ornaments mainly have the following two categories. \x0d\ (1) Emerald. That is, other jadeites pretend to be jadeites. There are mainly Thai jadeite and Malaysian jadeite, Nanyang dushan jade, Qinghai jadeite, Miyu, Australian jadeite and Dongling stone. The differences between the jadeite mentioned above and Burmese jadeite are as follows: First, the hardness is low; Second, low density (light weight) and weak luster. \x0d\(2) Green glass and green plastic. Most of these substitutes are dull and ugly, and their luster is very weak. The relative density is very light, the hardness is low (it can be carved with nails), and there is no cold feeling.
