How to buy silver is different, it is the same weight, and it feels good to be light or heavy

The ** of silver jewelry is not necessarily determined by weight, such as the old silver with a relatively long history, it depends on the quality of the workmanship, if there is no electroplating layer in silver jewelry, direct contact with air, even 99 silver will be oxidized and blackened, but you said that the appearance of cyan, that is because it contains copper.

Identification of silver jewelry. 1.Color identification method: observe with the eye, it looks white, shiny, fine, silver jewelry with high fineness, poor color, and dull are mostly fake silver jewelry.

2.Bending method: lightly fold silver jewelry by hand, which is easy to bend and not easy to break; stiff, barely folded, low fineness; After bending or striking with a hammer a few times, it will crack as colored silver jewelry, and it cannot withstand light folding, and it is easy to break is a fake.

3.Throwing method: Throw the silver jewelry from top to bottom on the plate, the bounce is not high, and the sound is stable for the silver jewelry with high fineness: Throw it on the table and jump high, and the sound is bright for the fake or low color silver jewelry.

Why does the same weight feel light and heavy?

Generally, the market is circulating 95 silver, that is, the purity is 95%, the hardness is larger, and other metals are plated into it, which is relatively bright.

In addition, it is purer than 99 silver, which is softer and can be felt by biting. But the color is generally darker because of oxidation.

Is this a question of IQ measurement? Isn't it the same weight and weight?

Silver jewelry is good.

1. Silver is a special metal, usually the higher the purity, the whiter the color, and after long-term storage, there will be oxidation and blackening, which will affect the surface luster of silver.

2. If it is silver jewelry made of silver, it will affect its aesthetics after blackening, so it is usually necessary to find a way to clean these black substances.

3. The easiest and most common way to clean off the blackened part of the silver is to use toothpaste, take out some of the toothpaste and apply it evenly to the silver with your hands, and then brush it with a soft-bristled toothbrush.

4. In addition, if there is strong tea overnight at home.

It can also wash away the blackened parts of the silver.

5. Put the silver in the overnight tea to soak for a period of time, and then wash the blackened parts repeatedly with the tea leaves, and gradually wash off after a few times, and then slightly use water to remove the tea stains on it.

Rinse off and you're good to go.

Not necessarily. The evaluation criterion for the quality of silver jewelry is not weight, but the purity of silver jewelry, and the higher purity of silver jewelry is better. Heavier is not necessarily pure silver, the international silver standard is 925, generally purchased is Miao silver, most of which contains low silver content, may be doped with tin, or copper and other metal substances, so it is heavier, the price is cheaper.

I am engaged in the silver jewelry industry, silver jewelry is heavier not necessarily pure silver, the international standard is 925, it may be that your friend bought the so-called Miao silver, most of which contains silver is not high, mixed with tin, or copper, so it is heavier, and the price is cheaper.

It is best to wear nothing and reduce the burden.

Silver is about twice as much as gold, and gold is denser than silver, so gold is heavier than silver.

For the same pound, the weight of gold is greater. It is heavier, just like a pound of iron and a pound of cotton, and a pound of iron feels heavier than a pound of cotton.

The main thing is the specific gravity. The specific gravity of gold is, and the specific gravity of silver is.

One gram is equal to one gram, and both belong to ***. where the density of ** is; Yes.

The density of ** is a multiple. Then the volume of one gram is a multiple of one gram, and l kilogram is heavier than 1 kilogram, and the density is higher than that of **, so the weight should also be higher.

It is gold that is heavier, and gold is denser than silver.

The density of gold,.

The density of silver,.

According to the mass formula, m = v, gold of the same size and silver have the same volume, and the density of gold is greater than that of silver, so gold is heavier.

The details are as follows:

Gold is an elemental form of the chemical element gold (AU), which is a soft, golden-yellow, corrosion-resistant element. Gold is one of the rarer, more precious and most valued metals of the slag nuclear system. Internationally, it is generally measured in ounces, and in ancient China, "two" was used as the unit of rolling laughter, which is a very important metal.

It is not only a special currency for reserves and investment, but also an important material for the jewelry industry, electronics industry, modern communications, aerospace industry and other sectors.

The chemical symbol is AU, and the financial English is XAU, or the name comes from a story of Aurora, the goddess of dawn in Roman mythology, which means shining dawn. <>

Hello, the quality of aluminum is very similar to silver but lighter than silver. Cupronickel alloy, nickel alloy, aluminum is very similar to silver, aluminum (aluminium) is a metal element, the element symbol is al, the atomic number is 13. Its single matte is a silvery-white light metal.

Malleable. Products are often made in sticks, sheets, foils, powders, bands, and filaments. In humid air, it can form an oxide film to prevent metal corrosion.

When heated in the air, the aluminium powder burns violently and emits a blinding white flame. Soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solutions, insoluble in water. Relative density.

Melting point 660 . Boiling point 2327. The content of aluminum in the earth's crust is second only to oxygen and silicon, ranking third, and is the most abundant metal element in the earth's crust.

The development of the three important industries of aviation, construction and automobile requires the unique properties of aluminum and its alloys, which greatly facilitates the production and application of this new metal aluminum. It is extremely versatile.

Gold is 88 grams heavier than silver.

The density of gold is centro centic, and the density of silver is centecor. One gram is equal to one gram, the density of the gram is a factor of Hu, the weight of a year-old pesan gram is 10 times 10 times multiplied by 193 grams, the weight of one gram is 10 times 10 times multiplied equals 105 grams, 193 minus 105 is equal to 88, and gold is 88 grams heavier than silver.

Gold and silver are called *** for the reason:

1. Gold and silver can be minted freely, and anyone can hand over the gold bar to the national mint to mint gold coins according to the gold content of the standard coin.

2. Gold and silver are the currency of unlimited legal compensation, with the right to unlimited means of payment.

3. The currency reserves of various countries are gold and silver, and international settlements also use gold and silver, and gold and silver can be freely exported and imported.

4. Because gold and silver can be freely transferred between countries, this ensures the relative stability of the foreign exchange market and the unity of the international financial market.

Beautiful color, strong chemical stability, stable properties, not much content in the crust, high transaction value. <>
