    I feel slightly dizzy
    It the fingers of nails to support my forehead
    Ahhhhhhhhhhhhhhhh
    Ah fake gold
    looks very young this year. nThe corner in the room where the sunset strongly illuminated
    This opened the refrigerator with a snap
    holding the milk that has not yet been opened
    Ah fake gold
    Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
    Different hands
    Sorry, sorry, still restrained by people last year
    Ahhhhhhhhhhhhhh
    Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh n Waiting for me this year
    The different shadows of the sun are different
    Different colors will change
    It, please wait for me to forget

  2. What are the use of fake gold jewelry?
    This are confused with gold jewelry include gold -plated jewelry, gold jewelry, copper jewelry, and copper alloy jewelry. The following briefly explain:
    The gold -plated jewelry is plated on the surface of other metal jewelry on the surface of the metal jewelry. The color is similar to the real gold jewelry, the golden light is bright, and it is difficult to recognize. However, the gold -plated jewelry feels lightly, the texture is hard, the teeth are bitter, and it is easy to fade with a long time. Some gold -plated gold -plated jewelry, the color is either red or white, or flowers.
    The packets of gold jewelry refers to 24K or 22K gold foil on other metal surfaces, such as the Kssean of the gold foil is too low, and its softness is poor. The appearance of the golden jewelry is similar to the real gold jewelry. The golden light is sparkling and it is not easy to fade, making it difficult to argue. However, if you carefully observe the depression, angle, back, etc. of the jewelry, you can find that the gold foil is uneven and there is a phenomenon of tilting edges. If there are broken joints on the jewelry, the cross section of the metal material can be seen from the outside. In addition, the feel of the gold jewelry is also lighter, the texture is harder than the pure gold jewelry, the teeth are bitter, and it is not easy to bend.
    The copper jewelry color is yellow with red, fake, darker luster, soft texture, and light weight. Copper alloy jewelry (copper tin alloy), white color, hard and light quality, long -term coloring, will make the skin darker.
    This jewelry is different from gold jewelry. If some jewelry is engraved with the English letter "GK", it means "gold plating". Or the signature traces are blurred and crooked. Consumers should identify whether there are printing, printing whether the printing is in compliance with the above provisions, and whether the printing is clear, etc. to determine the authenticity of gold jewelry.
    On how to distinguish the authenticity of gold?
    The appraisal method of gold jewelry has many methods, including color, weight, weight, listening sound, folding hardness, stone grinding, contrast cards, acid dots, and fixed color. The first four sentences depends on the eyes and the feeling; the latter four sentences need to be used by tools and reagents. There are also common methods -burning with fire.
    1. Seeing color
    Ben according to the different gloss and color of gold, you can generally distinguish pure gold, K gold, real gold, fake gold. That is, gold is better yellow (yellow -red), and the color is more than 95%; the positive yellow color is about 80%; the blue and yellow color is about 70%; the yellow color is slightly gray and the color is about 50%. Therefore, there is a formula for "seven green eight yellow, yellow nine five red, yellow leucorrhea ash pairs of gold". For jewelry from Jiu Tibet, there will be a saying that "copper turns green, silver turns black, and gold will never change color".
    2, 量 weight
    D gold weight is about double the same volume of silver, lead, and tin. True gold has a feeling of falling on the hand, while copper or others only have a sense of heavyness without falling.
    3, listening to the sound
    When the high -quality gold jewelry is knocked out or threw it hard, the dull and low sound of "click, click", there is no rhyme or elasticity, and K gold has sound charm. , Sound, elasticity, the greater the elasticity, the more the rhyme, the more the elderly, the worse the color. The fake or low golden sound is crispy but no dullness. Generally, the sound of "Dangdang" is emitted, and there are surplus sounds.
    4, folding hardness
    has a high color gold, and traces can be left with large head needles or nails. More than 97%of gold jewelry, after twisting two or three times, wrinkles appear at the bending, also called fish scales; about 95%of gold jewelry, it feels hard when bending, and the fish scales are not obvious; about 90%of the golden gold golden gold; The jewelry is very hard when the bending is bent, without fish scales; gold jewelry containing more impurities, bend twice or three times to break; if it is made for raw gold, the bend is broken. When using this method, the width and thickness of the jewelry should be considered. The thick and width should be hardened, and the thin and narrow ones are softer.
    5. Use the test goldstone to identify the color
    The use of the gold -pairing card (the gold medal identified as a color) and the subject's first jewelry on the test gold stone to determine the color of the gold jewelry through the contrast color. This method should be carried out under natural light and sunlight, and cannot be carried out under the direct sunlight and incandescent lamps.
    This in the past often used testing gold stones to determine the general content of gold. Testing gold stones are a mixed black mineral such as quartz and protein -containing quartz, and the gold is drawn on the test stone to see the general shape of the gold. Pure gold: shiny dark yellow, thick yellow; silver gold: light color change slightly green green; gold containing silver greater than 25%of gold: earth white; copper -containing gold: deeper color, red color tone; silver copper tone; Gold: yellow; gold containing zinc, same, nickel: white gold.
    6. Use acid dot
    The golden roads that have been identified and paired on the testing stone, respectively, and test the nitric acid on the golden road with a glass stick. Therefore, the color is unchanged. If it is not gold or non -pure gold, the Golden Road disappears or changes. The law of changes is "three fast, three slows", that is, the low color disappears quickly, and the high color disappears slowly; Depending on the disappearance of its golden road, compare cards can determine the color of gold jewelry.
    7. Burning with fire
    This will be used to burn red (do not melt the jewelry) with fire (do not melt the jewelry), and observe the color change after cooling. During different degrees, it is not pure gold. Generally, the lower the color, the stronger the color, and the darkens are all, indicating that it is a fake gold jewelry. After burning red, it is quenched into the water, and the color remains unchanged. It really does not change color when it comes to fire.
    The tests, two golds with different purifications, one containing a small amount of impurities, and one is a full -scale gold, which uses professional welding guns to boil, and the gold after burning is completely different. The color of the gold necklace with a low purity becomes darker, the section is rough, and the location of the welding medicine is obviously dark; and the golden foot gold still shows the bright golden nature of the gold, the melting surface is smooth and clean, and even brighter than the original.
    The soil method below to identify gold is not desirable
    Gold is one of the most wonderful metals in the world. Its chemical symbol AU is derived from the word Latin Charian Xia Xia, which means dawn, gold on the earth, gold on the earth, gold, gold on the earth, gold, gold, gold, gold, gold, and gold on the earth. The total reserves are about 4.8 billion tons, of which 99.7%are in the ground nuclear and mantles, and they can never be mined. The rest are distributed in the crust and seawater. It is very limited and the price is very expensive. Therefore, any point of gold prices will attract great attention from consumers. How to distinguish the authenticity of gold, the public has summarized a lot of methods in order to test the authenticity of gold. These well -known inspection methods are reliable.
    Rumors: Bite with your teeth, there must be bite marks
    The guests bite gold, copper, and silver tablets with their teeth, leaving obvious teeth bite marks on the three material.
    The truth: In the experiment, the hardness of the three substances was used. The hardness of the world's hardest solid material diamonds is 10, the hardness of Mohs of human teeth is 6-7, and the relative Mohi hardness of gold and silver is 2.5-3 and pure copper. Therefore, the hardness of many metal materials is hardness. It is relatively low, and the bite with teeth will leave obvious bite marks.
    The conclusion: Which of the gold is distinguished with teeth and which is not gold. There is no scientific basis.
    Rumors: Looking at the color, the more yellow, the more pure
    The on the scene has multiple necklaces. The guests think that the yellowest gold necklace is the most yellow.
    The truth: Use a tasting stone to detect which necklace is true. The results show that the color of the real gold necklace does not have other fake colors.
    The conclusion: The goldstone is a silicon rock with black colors. Draw some gold marks on the test stone, and then drip it with nitric acid. If the golden strip marks have not changed, it is real gold, because gold is insoluble in nitric acid. Experts say that golden yellow is the inherent physical properties of gold. Under the condition that there is no analysis and testing, it is not feasible to rely on the flesh to see the color to identify the authenticity. Because gold can be added to other elements and changes color, this identification method has no scientific basis.
    Rumors: Weighing, the more sinking the more
    The program scene, the host asked the guests to use the weight of the component to identify the true and false of the four different jewelry. Everyone agreed that the lightest jewelry was fake gold. The heaviest feel is real gold.
    The truth: The result of the use of professional instruments is that the guests agreed that the lightest gold jewelry is real gold. The heaviest feel is fake, all copper.
    The conclusion: The proportion of gold is about 19.32 grams per cubic centimeter, and the proportion of silver is about 10.5 grams per cubic centimeter. The density of gold is higher. Experts say that the golden component requires a lot of prerequisites, such as the volume, appearance, and shape of gold jewelry, and the size of the script requires certain experience. For example, people who can contact gold products every day. The best way is to use professional instruments to use professional instruments Testing, so it is not feasible to distinguish the true and false.
    Rumors: Use fire, no change
    In in a processing factory of gold and silver jewelry, use a gun with a temperature of more than 1,000 degrees to burn gold. The real gold is getting brighter and brighter. Become black. Subsequently, a bunch of gold completely melted with professional containers to make gold blocks, and see how the weight of gold changed before and after melting. The results showed that after the real gold jewelry became a gold bar, the weight did not change.
    The truth: The melting point of the gold is about 1064 degrees Celsius. When the flame reaches or exceeds the temperature, the gold will become liquid. Experts say that real gold is not afraid of fire refining the original intention. In the state of high temperature, pure gold will not be oxidized, and the color and weight will not change any change. Essence
    The conclusion: It is scientific to distinguish the real gold with the method of burning gold in fire, but for ordinary consumers, experts do not advocate this method, because to burn gold with a temperature of more than 1,000 degrees, is it? It is more dangerous, so this method is not the best way to distinguish between true and false.
