Some may be surprised by the fact that jewelryproducts are rarely made of pure material. This is due both to the properties of the precious metals themselves and to the fact that pure gold or silver can rarely be obtained. Clean products often have a different color and have different characteristics.
Silver, like other precious metals, you candilute with doping materials almost to infinity. This undoubtedly worsens its value. Visually distinguish qualitative silver from "diluted" is not so easy.
In order to somehow distinguish a fake fromof this article, and a sample system was introduced. It has been operating since 1927 and is still valid today in Russia and the CIS countries. According to the metric, the quality of the precious product is determined by the capacity of a pure material per 1000 grams. That is, if the sample of the product is 925, it means that in a kilogram of such an alloy, 925 grams of silver and 75 doping metals.
Looking ahead, we will report that the highest samplesilver - 960. But why not 1000? Silver itself is very soft material, and therefore it must be "strengthened" with nickel, copper, zinc or aluminum. Copper is most often used. In alliance with such metals, it acquires strength. It is worth noting that in Russia 80% alloys are officially considered non-precious.
Silver without sample, that is, the percentage of capacitybelow 80, is called technical metal. For the manufacture of jewelry such material is not used. But talking about its poor quality is not entirely correct. The fact is that it has increased strength. Metal due to its physical properties is an ideal material for the manufacture of parts for radio engineering. Silver is used in the manufacture of relays.
These privileges were obtained through light reflection and high electrical conductivity.
Theoretically from such silver it is possible to make and jewels, if to you the test is unprincipled. But then you should take into account that the metal is not considered precious.
Details about the samples of silver (what are the samples of silver) Let's talk further.
What are the samples of silver, we found out. Now consider their purpose.
Now you know the types of silver. What are the samples of silver and what sample is put on the finished product - found out. Next, let's talk about pure metal.
Silver, marked with the 999th test, is differentsoftness. It is pure metal, so it is not used for making jewelry. It is very easy to bend or break. If you make an ornament of pure silver, then besides that it will quickly lose its shape, its color will change instantly: the metal quickly oxidizes and becomes dull.
Modern technologies allow forgingjewelry so that it is almost impossible to distinguish them from the real ones. But still, no one canceled the return of the product for 14 days, therefore, having come home and belittling the new trinkets, we recommend to conduct simple tests that will help to determine approximately the composition.
Now you know what are the samples of silver. But how to determine the authenticity of the product?
Now we all know about this metal: what are the samples of silver, where are used. So, when buying a product, we can make the right choice.
