In the article: See purity label magnetism checks ice cube to check noise to check chemical test to blanch a test

Probably you are firm from a not quite reliable net inn redemptive a silver, also or the silver that you just got one is found accidentally then from the friend is acted the role of, or you want to examine suddenly the true bogus of an ancestral baby, so have you to learn the skill of true bogus of one reason silver? Silver is a kind of more active chemical element, standard silver is the silver of 92.5% adds the copper of 7.5% commonly, this kind of alloy is harder than pure silver. And simple silver-colored character is soft, also be called commonly " fine silver " . On the other hand, after a lot of implements are silver-gilt sufficient but mix the false with the genuine, the method of silver true bogus will examine for your introduction below.

Method 1

See purity sign

1

Seek purity sign. General metropolis has purity to label on the product that sells past world each district as silver, if there is mark on your silver, so this thing is likely also itself is pure silver, because it is,just produce by a country that does not need purity number.

2

Observe purity labels. Better with quality magnifier observes purity labels, on mark of the metropolis on the silver that sells past world each district commonly 925, 900 or such 800 numbers. These numbers are denotive the content that is the silver in silver, 925 express to contain the silver of 92.5% , 900 reach 800 to express to contain respectively 90% reach the silver of 80% , mix commonly in this kind of silver have copper, often also be called so " casting is silver-colored " .

Method 2

Magnetism checks

1

Look for a magnet. If you can find rare earth magnet (also be called neodymium) the word that waits for the magnet with very strong magnetism is best, such true bogus that you give silver with respect to can relaxed judgement, because silver is,do not have magnetic.

2

Stand by silver with magnet. If be true silver, magnet should be met not at all attract it. But, if you are used magnet is had exceed strong magnetism, so you may discover silver has shift a bit, because theory comes up,say, silver is paramagnetic after all. But if appear this kind of phenomenon, the magnetism that you use magnet is not general strong.

Those who want an attention is, also some metals do not have magnetism, mix into is in silver and can be not discovered euqally, so, besides magnet inspection, you are best other method comes to reoccupy test and verify.

3

Brae checks. If the silver on your hand is a silver bar, so you can have another test with magnet. silver bar inclined into 45 ° horn, put magnet next, if magnet can along silver bar surface slow slip below, silver bar should be true. This kind of method may do not have a truth it seems that, because silver does not have magnetism, but actually, the magnetic field of magnet itself can cause effect of apply the brake of a kind of electromagnetism, thereby slow down magnet slips the speed below.

Method 3

Ice cube checks

1

Prepare a few ice cube. Put ice cube in freezer first, when wanting to use, reassume comes out. Though ice cube follows silver to be done not have it seems that how old connection, but the just that actually this one test uses is the thermal conductivity with unapproachable silver.

This one test suits to examine silver and silver bar, but should examine the word of headgear has difficulty.

2

Put ice cube on silver directly. Do not change the line of vision, you can see ice cube begins to be dissolved quickly, be like it to be put on very very hot thing, on the thing that silver of and rather than is normal temperature this kind only same.

Method 4

Noise checks

1

Do noise test with coin. When colliding, silver can be given out the noise with euphonic general small bell, when colliding with other metal, be such more. If you want to do this test, be about to look for the coin that period of a bright Qing Dynasty distributes first, the coin that distributes because of that one period is silver more, and went to new China, coin is nickel more. Silver is compared by the noise when knock ringing, and nickel is compared by the noise when knock depressing.

2

Knock needs check silver. When beating, hands or feet wants a bit lighter, when using coin knock especially, leave impress easily on silver otherwise. If silver gives out ringing noise, explaining is to be tasted really; If give out, is depressing noise, so in this silver mix probably have a lot of other metals.

Method 5

Chemistry checks

1

Do chemical analysis to silver. If there is purity mark on silver, you can consider to do a chemistry to detect. Want to wear good glove above all, because you can use mordant acid in this one test,will examine purity, this kind of acid is to be able to corrode cutaneous.

Those who want an attention is, this kind of method may cause tiny harm to silver. If your silver will sell or if go off with makes identification, you still consider the article to fasten kind of method mediumly.

2

Buy tool of silver acerbity check. This kind of tool is in store of Yamaxun, Yi Bei and jewelry is OK buy. Tool of silver acerbity check suits to be used at examining pure silver or alloy, but if you suspect your implements is silver-gilt, that is about to make a number in proper place, what is so that make clear,the metal inside after all.

3

Search to manage not quite conspicuous place on silver, next above blow gently. Before watching the silver reaction to acid, this one pace is must. Wear in kit file of a metal child, blow a impress in the surface next, deepness wants enough to expose a metal of silver-gilt implements lower.

If you do not want to blow caustic your silver, also do not want to leave any impress, go buying flag of a black. This kind of flag is selling have so that sell in the inn of tool of silver acerbity check commonly, also can add along with kit sometimes give. Put silver in the attrition on black flag, leave a 2.5-3.75 centimeter broad line.

4

The local drop that has chafed in silver is acerbity. If acerbity droplet reached other place, that can affect the burnish of silver. If you are used, is black flag, the Na Daoyin that goes up with respect to flag then writes down an acerbity fluid.

5

Analyse a too acerbity surface. After silver of infiltration of fluid waiting for acid, you can begin to analyse this one color. Judge the purity of silver please according to measure of the following color:

Bright red: Pure silver

Dark red: 925 silver

Brown: 800 silver

Green: 500 silver

Yellow: Lead or stannum

Deep palm: Brass

Blue: Nickel

Method 6

Silver once bring into contact with resembles bleacher such oxidant, can become instantly dark and gloomy.

1

In bleacher of the drop on silver.

2

Observe the change that silver surface produces carefully. If silver pales to perhaps blacken instantly, so the purity of this silver is taller.

3

What want an attention nevertheless is, this kind of test does not examine to give silver-gilt implements.

Little hint

Want as far as possible from silver is bought over there reliable jeweller.

When having chemical test to silver, must wear good glove, because of nitric acid caustic very strong.

Warning

If did not take care to soak nitric acid on the skin, answer to be rinsed with water instantly, because nitric acid has very strong caustic. Rinse after ending, in the place that soaks nitric acid besmear nods bicarbonate natrium (namely sodium bicarbonate) .
