What is the fastest way to identify gold?

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.

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.

You can also listen to the sound identification, the purity of more than 99% ** will make a dull 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 vigorous the beating after landing, and the sound is brittle and no addiction.

3. Burn with fire.

It can also be identified by burning with fire, and being careful not to melt when burning red** with fire, the higher purity ** will be red and shiny after baking, and the ** with insufficient purity **will be gray and dark to varying degrees.

1、Observe for white bright spotsCut the gold bar or gold jewelry with material scissors, observe its cut surface with a magnifying glass, if you see white bright spots, because ** and iridium cannot be fused together, it means that the ** 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 whileto observe its 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 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.

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

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

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 quickest way to identify the soil at home is to use a magnetic test and an acidity test. These tests can help determine that **is genuine** and not an alloy of other minerals or metals. 1.

Magnetic test: If gold and silver items are placed in a magnetic field, if they can be adsorbed, it means that the silver content is high or mixed with magnetic substances such as iron. **Not magnetic, so it will not be attracted to magnets.

If **attracted, then it is likely that the stool is an alloy of iron, steel, or other magnetic metals and not pure**. 2.Acidity test:

Mixing a small portion of ** with hydrochloric acid, such as ** completely dissolved, indicates that it is an impure ** alloy. And if it doesn't dissolve, then it's likely to be pure. However, please note that acidity testing should be done with caution as hydrochloric acid is a strong acid that can cause damage and damage**, so it is necessary to wear gloves and goggles when performing the acidity test, and to perform it in a well-ventilated environment.

It should be noted that these tests are only preliminary identification methods, and for high-grade counterfeit and shoddy **, these methods may be ineffective. Therefore, if you want to identify ** more accurately, it is best to go to a regular gold and silver store or a professional institution for testing.
