Hammering is a subtle and highly artistic way of sheet metal processing, invented back in ancient Egypt. This method allows the creating real pictures on metal. The essence of the minting process consists in a metal treatment by means of a special metal rod - check which is placed vertically while striking a hammer on its upper end. As a result of the bottom blowing, working end (Combat) leaves its mark on the metal. Gradually moving the stamp, and each time hitting on it with a hammer, it’s possible to give to metal the desirable shape.
The special regarding to this kind of applied creativity is connected with coins stamping. This type of metal processing is one of the oldest. It was known in ancient Egypt, antique Greece and Rome, from ancient times – in Iran, China, India and Japan. In Renaissance period stamping has had development in the countries of the Western Europe. In the Middle Ages French and German goldsmiths reached technical perfection and plastic effect in a high stamping relief (especially in the presence of figures), in ?IV century — Italian, and in the end of XVI century – again the German masters. Stamping has achieved its high perfection in pre-Mongol Russ, and the blossoming — in Old Russian art of IV-XVII centuries. For example, cult character stamping products of Novgorod chasers of XI-XII centuries (salaries of icons, etc.) in which both Russian and the Byzantine art lines originally intertwine have remained.
Stamping continues to be applied and enriched with new techniques in modern decorative - applied art.
