Silver was open to humanity over 6,000 years ago. In those distant times, this noble metal was used as decorations of the images of Egyptian pharaohs. And the soldiers of Rome with his help heal the battle wounds.
Every year the popularity of silver increased. And today, this kind of precious metal is considered the most demanded in the world market. Despite the fact that silver mining has significantly decreased, every day enterprises engaged in the sale of silver metal in the form of jewelry, scenery and household items open in small cities and metropolis.

Jewelers argue that black silver is a classic of the genre of precious metals. It uses a black alloy for its creation, which contains copper, silver, sulfur and lead in different shares. This alloy is added in the process of creating products with one of several ways. For example, chasing, engraving, credit or etching.
From the temperature effects between genuine silver and its complementary alloy, a reaction occurs, due to which the product receives not only decorativeness and beauty, but also becomes practical.

The technique of the blackness of the noble metal has a lot in common with the technique of the lavetled enamel. However, the lavetled enamel must be prepared separately, and immediately apply a mixture on a silver product with subsequent firing.
To date, 3 fashion methods are used with extensive demand, namely, the German, modern and pre-revolutionary Russian.
For application German fashion It is necessary to carefully add lead in a copper-silver melting mixture, constantly stirring a thick mass. After the pione of the lead add sulfur powder and water. Ready pieces of mobile are rubbed in the necessary dosage to the state of the powder with the help of a special stupa. Then applied to the product in a grip form.
An old recipe suggests The use of a similar triple alloy added portion. The prepared mixture is then transfers to the cast-iron container and remains in it until hardening. The prepared pancake breaks into small pieces and is overjugated again, but a flux and sulfur is added to it.
Pre-revolutionary Russian method of blunders developed by Professor Spassky. Its essence lies in a separate cooking of silver, sulfur lead and sulfur copper. Then they combine in the container, creating a single alloy. The thick mixture reuses the melting procedure according to the unique technology of the professor. And only after that postponed to complete cold.
