As a result of the research conducted, it is established that ancient granulated jewelry is made of silver (Ag) of 90-96% purity and gold (Au) of 75 % purity or higher. All the items under study are affected by intercrystalline corrosion. The solder which fuses the base to the granules is especially subject to destruction. In restoration, the alternative use of mechanical and chemical cleaning, together with heat treatment, make it possible to achieve a comparatively stable crystalline structure of the metal (Ag, Au) and to turn the larger amount of the corrosion compound into silver and copper complementing the composition of the solder which fuses into it. Temperatures of 450°C, 650°C, and 850°C were used. It is defined that while soldering silver, ancient mastercraftsmen used the double alloy of silver-copper and the triple alloy of gold-silver-copper. The technnology of making granulated silver and gold is also presented.
