Instruction
1. If you assume to get a product from silver online, then reduction "serebr can occur in many announcements of sale to you." Such not perceptible reduction, as a rule, means that the product silvered, that is the silver layer is applied on a metal base. The reduction stated above gives the unfair seller a chance to sell to the buyer, inexperienced in these questions, the silvered thing at the silver price. Be attentive.
2. On various network second-hand markets some sellers deliberately write in the beginning of the name of the product "silver", but on closer examination it becomes clear that only the covering is silver. As justification the sellers explain that the instruction on silver in the name only goods to category of the products containing silver. Therefore when tendering do not hesitate to ask the specifying questions.
3. Pay attention to the marking executed in foreign languages. One more trick of sellers is that in the name of material of which the product is made costs ""silver pl."" or ""silver plated"". ""Silver"" is really translated as "silver", but in combination with the word ""plated"" means "covered with silver" (a metal base with silvering).
4. If the photo without brand of assay chamber is attached to the description of a product, demand from the seller of new photos. The best way to establish authenticity of a silver product is to see on it besides a brand of the manufacturer the brand confirming that the product is made of silver.
5. At visual inspection of a product pay attention to cambers of a subject and its bends. As in such places the thing most often is exposed to mechanical influence, under the top layer metal of other color and a shade can appear.
6. Smooth out a small surface of a product from stratifications and drip on this place iodine. Under the influence of sunshine, silver darkens (from a muddy yellowish film till black color).
7. Apply on the checked product the tiny line with a lyapisny pencil. Silver has to dim, and any copper connection (bronze, brass, cupronickel) will violently turn black. The place where you carried out tests, after the experiment will need to be polished.
