All about silver samples

All about silver samples

The popularity of silver products in society is caused by their visual and technical characteristics. On silver, as on other precious metals, there are samples. They may differ on products manufactured in the Russian Federation and in other countries. Samples differ depending on the composition of the alloy and the purpose of products.

For what is needed?

To regulate the number of impurities and confidence of the buyer, the so-called samples appeared as a product. According to them, the ratio of silver to the impurities in the alloy is determined. On silver products sample stamps in the form of stamps. Its location may be different. Small size mark easy to find things. If you find it fails, there is a possibility that the sample was lost or it was not originally.

The easiest way to determine the authenticity of the silver product will be an appeal to specialists in a jewelry store or pawnshop. You can contact them State inspection of the assumption, where they will hold a qualified test analysis. According to the query results, the quality of the goods from silver will be made.

If desired, it is possible to specify the authenticity of the silver product on one’s own. For this you will not need any special devices. Although the exact sample is so determined unreal.

Silver – metal with high thermal conductivity. So, if you immerse the thing in boiling water and immediately remove, silver warms up to the water temperature.

Check authenticity is possible and by the help of a magnet, since silver with high sample marking is not attracted.

Another way to check – iodine. It is enough to drop on the product and look at the metal reaction. On the real silver there should be a dark spot. In addition, the darkening on high-quality metal leaves and contact with chalk. To show yourself a fake can and with time. The quality product will not oxidize, it will not appear on it and corrosion. For all listed manifestations it becomes clear that many third-party additives are mixed in the product.

Conditionally, all silver products are divided into quality groups. Silver without impurities is too flexible and make dishes from it or use for jewelry is not possible technically. In order for the product to keep the form, ligatures are mixed in the precaMaltal. Various elements are used as impurities. For this reason, to determine the “purity” and direct metal content (in this case of silver), the term “sample”.

Simply put, The trial will be recognized in which volume is pure metal contained in a specific alloy. For example, in a sample 800 – 1 kg of material accounts for 800 g of silver and 200 g of other inclusions. Traditionally, copper is used as an impurity, but the more such a metal in the alloy, the sooner the silver product will darken or yellow.

Nickel impurities are found – nickel content up to 1% allows you to improve the alloy by mechanical properties. In the precious ornaments in microscopic fractions, lead, iron, antimony and bismuth are contained. Zinc and cadmium is also allowed – these compounds are used in the manufacture of silver solders.

What are there?

Samples of silver rank based on the percentage of pure substance in the alloy – from 600 to 999. Silver in pure form is characterized by a soft silver tinge, long does not darken, it is easy to clean, but there are conditions affecting the type of metal. It depends on the sample or from the volume of impurities included in the alloy.

Buyers often worries the question –What a sample can be silver? The pursuing of Russian silver products occurs according to the adopted international standards. Often, copper is added to the alloy, perfectly interacting with silver. Subject to the addition of cadmium, the manufactured thing is tangible in price. Also with silver can mix nickel, zinc and aluminum, but copper in alloy is a classic.

The greater the number of ligatures in silver, the more clearly its shade.

How to determine the quality of silver? For example, decorations under marking 600 There is a noticeable red shade – from large copper content. Such things threatens soon oxidation (silver is not oxidized by itself, and copper is peculiar).

Alloys 800, 830 Used to create souvenir products and cutlery. For decorations the most suitable – 875 and 925 (less often 960). The 925th sample says that 1 kilogram of pure silver accounts for 75 g of impurities.

In high-quality samples contain at least 916 g of silver per 1 kg of alloy. Standardly made sets decorated with gilding or enamel-covered. 960th sample often occurs on silver rings, earrings, grains or chains. Properties of this alloy are practically not inferior to pure precious metal. Significant silver content gives things softness and plasticity. Decorations are sophisticated and spectacular, but need careful handling and good care.

Sample 750 Indicates low-quality silver, which is not considered precious metal and does not even always have labeling. Things from this alloy are quickly oxidized and black, acquire a characteristic shade of yellowness. The alloy is used in the field of electronics in the manufacture of boards and other parts.

There are 985 samples and even 625. The first one relates to a precious group, but not often used. The second is considered low-grade and occurs extremely rarely.

Alloys today are created quite a few, some manufacturers use their samples, for example, TM Sunlight products often go with labeling SL 926. Also silver is divided by types, the most famous of which are presented below.

Potted

Potted silver is not an alloy. Raming it is customary to call the technique of galvanic (electrolytic) coating. The surface of the product is covered with thin (about 0.25 μm) layer of rare durable metal rhodium. Rhodium coating most often used for highly subject things. Such decorations acquire obvious advantages:

  • Shining shine – brighter than clean silver+
  • Resistance to damage and deformation+
  • confrontation of corrosion and color change.

Sterling

Sterling silver called alloy 925 sample, which is sold in all stores and from which the vast majority of jewelry. The name of this type of silver leaves its roots in the history of Britain. Such silver in the XII century by decree of the King Henry II was used for standard sterling stamping.

There are several versions of the origin of the term “sterling” related to the names of old coins, which were calculated in Germany and Normandy.

Black

Like a bought black silver is a variety of metal coated. Black is called silver coating with oxide film to imitate oxidation. Technique originated in Russia in the XVII century, Thanks to which household items decorated with miniature patterns.

In modern times, with the help of such silver, decorations are stylized. There are three types of blacks, characterized by technology: chemical, galvanic and mechanical.

You can make blacks and at home, using iodine and sulfur ointment.

Filigree

Filigree or Skan – Name of thin wire pattern and grains over the product. Maybe the background when the metal sheet is part of the product or openwork, if the source sheet is removed, leaving elegant lace from silver. Filigree is found in any museums, where the expositions of the noble life are presented: Silver spoons, cup holders, stands under the tables. This elegant technique is characteristic of the times of Tsarist Russia, it is valued abroad for the original Russian flavor.

Matov

Matting is achieved by creating microscopic roughness on the surface of silver. The process is carried out using a sandblasting machine. Rough surface can not be polished, it rarely serves to frame stones. For gems more suitable glossy glitter silver.

Matte silver looks in the neighborhood with a brilliant “classic” – in products by type of double ring or chain with alternating links. Matting technique is used when creating geometric and plant ornaments.

Sustal

Like tinted gold, Used to cover objects with a solid layer. Thin sheets of gravestone silver are used to decorate in the interiors of temples and in the palaces. This metal has the highest test. It is not suitable for the coating of domes, since it is not distinguished by resistance to external influences, in contrast to gold, for example. Such a metal needs additional coverage.

In the old days, egg protein was used for this, and now it was replaced by waterproof varnishes.

Colloidal

Metal dispersion in the form of suspension of nano- and microparticles is used in the sphere of cosmetology and in non-traditional medicine procedures. So far, there is no confirmed evidence of the effectiveness of dispersed silver, the results of the experiments carried out with him. Colloidal silver sold in solution as bad (biologically active additive).

Table

Until 1927 in Russia enjoyed the metric system. In the USSR, the standard silver has labeling of the 875th sample (84 – according to the spool system). It is still applied, along with the 925th, popular in Europe until the XX century. Now available any listed coverage. You can refer to the jeweler if you wish to process your favorite silver spoon, rhodium to strengthen or if she swept.

Technical

Phrase “technical silver” ambiguous. Technical Call Radio Engineering and Metal, used in electronics (for contacts), electrician (in wires), phototechnology (for X-ray). This is High sample inert silver, Not refractory and flexible, having good electric and thermal conductivity.

In Russia

All ligatural inclusions in silver alloys are a different percentage. Someone considers 5-12% sufficient additives, and other jewelers add to the precious metal to 50% of ligatures. Jewelers in Russia work with silver since the 720th sample. From alloy 800 samples make tanks for spices, drinking, oils, cutlery and other kitchen items. For such products requires good regular care. The silver of the 875th sample is defined as a base.

Separately worth saying About tsarist silver with a stigm of the 84th sample. Now it is actually not found, unless in the family settings, museum expositions, antique shops and flea markets. Silver 84 sample was in the go in pre-revolutionary Russia. Then we used the measurement system in spools.

Pure metal mass in such a product is 0.88 g. Silver this sample is considered to be rare, a kind of echo of the historical past.

In the world

There are various silver samples. In developing countries, use is allowed 600-y. Minimally acceptable believes 800 sample. The rest of the world is much a richer assortment: in Europe in the go 800th, 916th and 925th. But there are also its special samples, for example, in Egypt, it is 600th, and in China, they worship silver almost without additives.

In Far Eastern countries and Japan, there are silver products with a higher sample stamp – 1000. Locals are attributed to the metal mystical power, considering that he has a connection with the moon. In addition to the samples described above, there are others in the world, but it is the above options that are most popular among jewelers.

    Alloys are distinguished by systems that differ in different countries: in the USA and Canada – carat, in the old days – the excavation (for example, the 960 sample silver is defined as 92SF). Other varieties of alloys are found:

    • 750 – silver with high copper content, prone to very rapid darkening+
    • 720 and lower – refers to non-precious silver, with a yellowish tinge, will be applied in industry due to the high conductivity of the electric flow.

    There are also such rare types of silver samples:

    • 325 – Tibetan silver, previously related to high-quality alloys, was used for the manufacture of jewelry, now in composition may not be precious metals, from alloy often create fakes+
    • 500 – alloy containing a low share of silver, coins minted from it+
    • 525, 585, 625 – silver with the addition of gold, gold-plated silver+
    • 825 – non-existent proba, which fraudsters often put on products+
    • 835, 800 and 900 – Silver alloys that are in Germany+
    • 916 – Popular sample of Soviet times with a stamp-barrel, alloy used for dishes and products of ritual destination.

    What is the highest test?

    The highest sample that occurs on sale – 960th, with a small amount of copper. The most expensive alloy – 999. There are no extraneous inclusions in it. The soft material is prone to deformation, for this reason applies only for solder in devices. It is realized in the ingots.

    The remaining samples are evaluated as the volume of ligature increases. The smaller the number of labeling, the less value has a thing. Some circumstances need to be considered if it comes to antiques. Here the value is not the sample itself, but the originality of the product and what the century it belongs to. The earlier the thing was made, the higher it is appreciated.

    Best Silver Sample for Jewelry – 925th. Decorations from this alloy are whiter than others and more brilliant. The color of less high-quality metal is somewhat dull. High purity is not good in all cases. Jewelers perform locks for chains and bracelets made of metal breakdown lower than the bracelet itself (720 or 750). This technique prolongs the life of the decoration.

    It is important to have an idea of ​​what the 925 sample looks like silver, as well as other stamps, where to look for a product sample and how to determine its authenticity. The presence of a mark of impurities will allow to understand where it originated the subject, the name of the jeweler or the name of the enterprise, as well as what breakdown was labeled with a silver product.

    The price of the gram of silver 925 samples in Russia today is 45-120 rubles. The cost depends on the mass of the product, manufacturer, labeling, the course of silver assessment on international exchanges, charges for retail. Navigate the best on the average cost in the pawnshops.

    Expensive silver may well be just the result of a disproportionate mark.

    Interesting Facts

    In some countries, silver put a stamp indicating alloy samples, but with some additions. In England, until 1300, the head of the British Lion was depicted on the stamps, and in the future each city had her own mark. In Russia, on the brand mandatory was the mark 84, corresponding to the 875th sample. In Germany, before the introduction of a metric system on a product of such a sample stood with “14”.

    In some cases, we can go about the stamp of the master with an individual image or initials of a jeweler, which made a thing. The presence of stigma indicates the authenticity of the product. Nevertheless, there are cases when false tests are found on the dishes and decorations. Different fake thing from precious can only professional.

      Once in antiquity of silver 925 samples made English coins – sterling. There is a legend that sterling silver appeared in Saxony, in the area of ​​esterling. From here it took its name. Sterling alloy made coins for calculating goods with English traders. And only after that, a pound sterling appeared in Britain. An old alloy was considered very high quality, it is still highly appreciated and used for the manufacture of jewelry and decor items.

      At various times, different silver-based alloys were popular. Each of them had a special form and their own scope:

      • Black silver – Used in Russia to create elegant black patterns on products+
      • oxidized silver – The alloy of silver and sulfur, prone to the darkening, is an analogue of the blackness, maybe with a purple subtock+
      • Matte silver – silver coating, resistant to oxidation process, was used even during the heyday of the Russian Empire+
      • Gold plated silver – spraying of a thin layer of gold, popular in France XIX century.
