What color does fake gold burn? What color is gold when it is burned with fire?

What color is the fake gold burned, and the real **after burning**.

**Jewelry is a fashionable jewelry for thousands of years. There are many kinds of jewelry that are very easy to get confused with ** jewelry. Some are gold-plated jewelry, some are gold-plated jewelry, some are copper jewelry, and some are alloy copper jewelry.

So what does the fake ** look like, after the real gold is burned? Let's teach us how to identify pure gold.

The gold remains pale yellow when lit with fire. As the saying goes, "real gold is not afraid of fire", which means that the ** jewelry will show pale yellow again after ignition and will not be deformed. If lit it turns orange-red.

This is also routine, since the ** jewelry is not 100% pure gold, it can be restored to the previous hue after cleaning.

Distinguish the ornaments by roasting them over fire (no need to melt them) and observe the color change after cooling. If the surface is pale yellow, it is pure gold; If there is a difference in the level of darkening or blackening of the hue, it is not pure gold. Generally, the lower the condition, the stronger the tone, and all the changes indicate that it is fake ** jewelry.

Ignition can only tell whether it is pure gold or not. Pure gold does not fade easily when ignited. It's fake gold or some other ingredient of gold, so it's impossible to tell.

In fact, the ** jewelry you buy from basic well-known brands or customized well-known brands will be affixed with recognition logos, and they have passed the organization testing, so you can buy with confidence.

In day-to-day identification, it is not necessary to have direct contact with gold products. Once the rash occurs, you can ask professional and technical personnel to burn the gold products in the fire to solve the difficulties, and it is basically impossible to endanger the quality of the gold products. You don't have to be curious to experiment on your own.

Especially if you don't have to wear a necklace or other tiny jewelry, you don't have to try it at will, because the temperature control is not very good, the jewelry will undoubtedly deform. You also need to pay attention to whether it is pure gold jewelry, if it is not pure gold, the fire will undoubtedly turn black, then it is not worth it.

Fake gold is black when burned.

Summary. Fire identification ** jewelry authenticity"Seven green, eight yellow, nine with red, four or six are not gold"After being burned, look at the color of the jewelry:

Seven blue, refers to seventy percent (containing gold 70) of the ** presented by the color of green and yellow. Eight yellow, refers to eighty percent (containing gold 80) of the ** presented by the color of positive yellow. Nine with red refers to ninety, the color of the ** above 95 is dark red yellow, and the color of the ** of 90--95 is light red yellow.

Forty-six is not gold, refers to the color is lower than sixty percent (including 60), the color presented is not the color that the ** has, sixty percent of the ** is white in the yellowish, forty percent of the **, the color is completely white.

After roasting it over fire, can it be restored to this color? Is this necklace real?

Dear, real gold can be recovered, you brush it with toothpaste, if it is real gold, it will change back.

I washed it with toothpaste, and it still hasn't changed back.

So this is a fake.

That's right, dear.

Truth and falsehood are not afraid of fire.

Is there a way to get him back to his original color.

Dear, no, this one has changed color.

False** burns not black is:Copper-zinc alloyMaterial. The so-called true surface plating refers to: black merchants use the color of the surface to deceive consumers.

First of all, they will prepare the "** jewelry" to be disguised in advance, that is, copper or silver jewelry, and electroplate a layer of real ** water on the surface of the jewelry (that is, like rusty iron, brush a layer of gold paint on the surface to achieve the effect of camouflaging the true color inside).

In this way, if you look at it on the surface, you will find that it is exactly the same as the real ** jewelry. So how to distinguish this fake ** jewelry? In fact, it is also very simple, the surface is plated with a layer of ** color, just prepare a needle or knife to gently scratch on the surface.

Just look at whether the color of the inside is the same as the appearance, of course, there is a way that will not be damaged, that is, prepare a hard sponge and squeeze some toothpaste or lipstick on it, you can also wipe off the surface of the electroplated **.

Fake "** jewelry, what material is it made of?

The first type: true ** surface plating.

This method is one of the most common and economical methods. This method is to create a real "illusion" to deceive consumers, they will first prepare copper or silver jewelry, and then smear a layer of real ** water on the jewelry, which can cover the original color of the copper or silver jewelry inside.

On the surface, you will find that the appearance is exactly the same as the real ** jewelry, so that you can confuse the real thing. So how do you tell the difference?

If you are a little violent, you can directly use a needle or a knife to scratch it to see if the color inside is the same as the color outside, you can distinguish it, of course, in addition to this method, you can also prepare a hard sponge, apply some toothpaste or lipstick on it, wipe it, and wipe off the electroplating ** on it, easy to distinguish!

The second type: gold-filled process.

The principle of this method is similar to the above method, the biggest difference is that the cost of this method is much higher, because this is on the surface of copper or silver ornaments, with a layer of thicker true ** squeezed and wrapped by **thin sheets, which is particularly time-consuming, so this method is aimed at heavier jewelry, generally more than 10 grams.

If it is too light, it will not be cost-effective, and the fake ** jewelry made in this way is difficult for ordinary people to find, even if it is burned with a blade or live fire, it can not be found, but it also has a loophole, the fake ** jewelry made by this red method is generally ugly, large in size, and gives people the feeling of light grams!

The third type: real gold adulteration.

Real gold adulteration, as the name suggests, is still to ** as raw materials, and then will be mixed with a large number of copper and silver raw materials, in order to achieve the purpose of increasing the number of grams to make profits, for example, to make a 10 grams of **, will prepare 5 grams of **, and then mixed with 5 grams of copper or silver.

This production method is very simple, and it is easy to distinguish, as long as you burn it with a lighter, you can know the truth or falsehood, generally speaking, it will not change color after touching the fire, and the ** flowers mixed with other materials appear to change color, burn it in the same position with a for 20 seconds, you can see the effect!

Summary. Put the gold bars or gold jewelry on the fire for a while and observe the 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.

As a kind of ***, it has good physical characteristics, and "real gold is not afraid of fire" means that it is not easy to melt under the general flame. High density and heavy feel. Good toughness and ductility, good conductivity.

Pure gold has a brilliant yellow color, but the color changes greatly when mixed with other metals, such as dark red for gold-copper alloys and light yellow or off-white for silver-containing alloys. Gold is easily ground into powder, which is why gold is dispersed in nature, and pure gold jewelry is also easy to be worn down to reduce the weight.

Hello, can you send **.

What the gold was burned into.

First: it's real gold.

Second: black things are out of the way because of the time they are worn.

Third, it is necessary to observe whether the color of the gold has changed, if there is a change, or the color is not as bright as the previous color after burning, it proves that the purity is not high, at least it has not reached pure gold, or pure gold.

The purity, because you don't have **, can only be speculated.

Extended information: 1. Look at the color: **The higher the purity of the jewelry, the darker the color.

In the absence of a gold medal, the general fineness can be determined according to the following colors (based on lapis and gold. The so-called lapis gold is only contained**ingredients): dark red yellow color is more than 95%, light red yellow 90% 95%, light yellow is 80% 85%, blue yellow 65% 70%, color blue with white light is only 50% 60%, slightly yellow and white is less than 50%.

The commonly said seven green, eight yellow, and nine red can be used as a reference.

2. Weight: The specific gravity of ** is 1932, which is heavier than silver, copper, lead, zinc, aluminum and other metals. Like the volume of ** heavier than ** more than 40%, heavier than copper, heavier than aluminum.

**Jewelry should have a sense of sinking in the hand, and fake gold jewelry feels light. This method does not apply to ** jewelry inlaid with gemstones.

3. Look at the hardness: pure gold is soft, low hardness, shallow marks can be scratched with nails, teeth can leave tooth marks, ** jewelry with high fineness is softer than low fineness, the more copper content, the harder it is, and the bending method can also test the hardness, pure gold is soft and easy to bend, and the lower the purity, the less easy it is to bend. If it is made of raw gold, it is broken when bent, and the section has obvious sand grains.

If you're worried about the future, it's better to work hard now. On this road, only struggle can give you a sense of security. Don't easily pin your dreams on someone, and don't care too much about the whispers around you, because the future is your own, and only you can give yourself the greatest sense of security.

Don't forget what you promised to do, and don't forget where you want to go, no matter how hard it is or how far away.

It can prove that we have a correct and rational view is a delicate question.

How to restore. I burned it black and purple with a gas stove.

How to restore the original color.

What about people. Wait a minute.

After burning red, it will be dipped with 1:3 hydrochloric acid solution to restore close to the original color, and the effect will be more restored after polishing, but it will definitely not reach the luster of the original goods, and the original color will be restored after re-plating.

You refer to it.

Look at the color.
