The soil method for identifying gold, the fastest soil method for identifying gold

It takes a certain amount of experience to identify**, and the color and luster of various colors are different. After a long period of practice and analysis, people have also summed up some simple basic identification methods.

Color and gloss identification:"Seven green, eight yellow, nine with red, four or six are not gold"This mantra is one of the ways to identify the best color. Seven green refers to seventy percent (containing 70% gold) of the ** presented by the color of green and yellow.

Eight yellow, refers to eighty percent (80% of gold) ** presented by the color of positive yellow. Nine with red refers to ninety, more than 95% of the ** presented color is dark red yellow, 90-95% of the ** presented color is light red yellow. Forty-six is not gold, refers to the color of less than sixty percent (including 60%), the color presented is no longer the color of the **, less than sixty percent of the ** is white in the yellow, forty percent of the **, the color is completely white.

Fire identification: As the saying goes:"Real gold is not afraid of fire"。**Does not melt and does not change color at high temperatures of thousands of degrees. According to this, it can be burned on the fire, that is, it can distinguish the real from the fake.

Weight: **The density is greater than that of common metals such as copper and silver. The weight of the same volume is twice the weight of copper and the weight of silver.

Therefore, the quantity is measured by hand, and then according to the size of its volume, the authenticity can be determined. **There is a heavy feeling when you touch it with your hand, that's what it says"Gold Pendant Hand"and, on the contrary, fluttering.

Listen to the rhyme: Throw the ** in a hard place, and the ** with high color will be issued"Puff puff puff"The sound is muffled and unrhymed, and it rarely bounces after landing. After the ** with low color is thrown to the ground, its voice is slightly sharp and slightly high, and it has a slightly short rhyme.

And the copper ornament was sent out after it was thrown to the ground"Dangdang"Ringing, this sound is high and high-pitched, and the sound is long and rhymed. There is a bounce after the throw.

Fold soft and hard: high fineness ** fold and soft; The fineness is secondary, and the hardness increases; The physical folding of copper bars is laborious and elastic. ** with high color is drawn with a pin (nails, teeth can be bitten), and the force is not large but the traces are obvious; If it is a brass ornament when scratched with a pin, the force is large and the marks are blurred, and the nails are scratched without traces.

The place where the ** is sold is generally authentic, or you can test it with dilute sulfuric acid yourself, and if there are no bubbles in it, it is true; If there are bubbles, the instructions are fake. Or take it to 12315 and ask them to test it.

1、Observe for white bright spotsIf you see white bright spots, because ** and iridium cannot be fused together, it means that ** is mixed with iridium.

Listen to the sounds,When the ** jewelry with high fineness is knocked or thrown to the hard ground, it makes a dull low sound of "poof, poof", with sound without rhyme and without elasticity, K gold has rhyme, sound, elasticity, the greater the elasticity, the sharper the rhyme, the older the color. Fake or low-color** sound is brittle and no dullness, generally makes a "dangdang" sound, and the sound has an aftersound, and beats violently after landing.

Start by measuring the weight of a pure gold bar with a balance, then put the gold bar in a measuring cup and pour water to cover the gold bar. Then put the gold bar to be tested into the measuring cup, observe whether the scale of the water rises or falls, as long as it changes, it means that the gold bar is not pure gold. However, this method does not apply to gold jewelry, because there is air in it.

Put the gold bars or gold jewelry on the fire and burn them for a whileObserve how it changes. Because iridium will oxidize with oxygen in the air, gold bars of insufficient purity will turn gray; Pure gold, on the other hand, will be red and shiny in color after being roasted by fire. However, this method may be destructive to jewelry.

The master will teach you a few tricks to identify the fastest soil method.

According to the data on the tree, the fastest way to be firm is to calculate the overall mass and density.

The method of identifying ** soil is to burn, **there is a saying that real gold is not afraid of fire refining, that is**use fire to burn, after burning** the surface is still golden, and there is no blackening and oxidation now.

If it is burned too much, it will not change color and it is real gold.

Summary. Look for the official logo, which will indicate the degree of **. Look for fading and check where the gold is most likely to wear out.

Or weigh it by hand, ** is about twice as heavy as silver and lead of the same volume, and the real ** is in the hand, it is a feeling of falling, and copper or other substances, only a sense of weight, no sense of falling. **You can also use the aural method to identify, when you throw ** to the ground, the high gold content ** will make a "pop" sound, and there is no rhyme and no elasticity. The ** with low color contains more other metal components, and the sound is long and elastic after landing.

Look for the official logo, which will indicate the degree of cleansing. Look for fading and check where the gold is most likely to wear out. Or weigh it by hand, ** is about twice as heavy as silver and lead in the same volume, and the real ** base on the hand is a feeling of falling, while copper or other substances, only a sense of weight, no sense of falling.

**You can also use the aural hearing method to identify, when you throw ** to the ground, the high gold content ** will make a "pop" sound, and there is no rhyme and no elasticity. The ** with low color contains more other metal components, and the sound is long and elastic after landing.

You've done a great job! Can you elaborate on that?

1. Look at the color? There are many ways to identify **, such as looking at color identification**, the higher the purity of the jewelry, the darker the color and color, and you can also weigh the weight to identify, and the high purity ** has a deep feeling of falling in the hand, but this method is not suitable for inlaid jewelry. 2. Listen to the sound can also listen to the sound identification, the purity of more than 99% ** will make a dull low sound of pop and pop when thrown on hard ground, there is no rhyme and no bullet, if it is doped with other substances, the greater the elasticity, the more the world trembles and beats violently after landing, and the sound is brittle without a sense of addiction.

3. Burning with fire can also be identified**, burning red with fire**Be careful not to melt, the purity is relatively high** will be red and shiny after the roasted hole, and the purity is not enough** will be gray and dark to varying degrees.

Hello, glad to answer for you. The fastest methods to identify the best soil are: 1. Fire burning method, real ** jewelry, burned with a fierce fire, can be durable and does not change color, counterfeit and shoddy will become black and brown, and will lose the brightness of **.

2. Eye viewing method, look at the color of the **, according to the different light colors and colors, you can identify the true and false of the **, the real ** is mainly red yellow, that is, yellow-red, and the color is basically in 95%. 3. Ear listening method, high-quality ** jewelry, when being struck, or thrown out, emitting a dull low sound of "poof, poof", there is no rhyme and no pressure, the greater the elasticity, the sharper and longer the rhyme. 4. Hand weighing method, weighing by hand, ** is about twice as heavy as silver and lead in the same volume, and the real ** is in the hand, there is a feeling of falling, and copper or other substances, only a sense of weight, no sense of falling.

The fastest methods for identifying soil are: fire method, weight method, listening method and so on.

1. Fire burning method.

The easiest and most accurate way to identify ** is to burn it with fire, ** when it is burned by a high-temperature musket, it will only produce a melted color will not change, and in the end it will become gold water, if the discoloration indicates that it is not**or** the content is low. You can also test it with a knife and scratch it on the ** with a knife, because the purer the softer the softer, so it is really easy to leave traces.

2. Weigh the law.

The specific gravity of ** is much greater than that of other metals, a pure gold the size of an ordinary matchbox weighs more than a catty, and the same size of silver or copper, only less than half of the weight of **, so experienced people can be roughly determined by hand imitation resistance.

3. Listening method.

Throw ** on the concrete floor of Beifeng Spring, if it makes a sharp and long, rhymed sound is not**. Only those who make dull noises and have no rhyme are the real **. And**the purer the softer, so when **thrown on the concrete floor, it should be inelastic, and those that bounce up are not true**.

Precautions for buying**:

1. Look at the weight: the specific gravity of gold is, the color development has a large relationship with the specific gravity, and when the specific gravity is close, the higher the pure gold content. Measuring the specific gravity can know the color development of the jewelry, but it is generally available. If something feels a little heavy, you can sense it.

2. Choose a regular**store: When buying**, please choose a more formal, large-scale, and long-established **store. The quality ***, the technology of the ** jewelry must be better.

3. When purchasing, please choose. For example, thousands of pure gold, etc. This kind of gold is very bright, of high purity, and looks even higher.

4. Confirm the weight of **: In addition to the quality, the weight of ** is also one of the factors that need to be confirmed when purchasing. Under normal circumstances, the weight of ** is measured in grams, and it is necessary to confirm whether the weight of ** is accurate when purchasing, and carry out ** accounting according to the actual situation.
