Composition of silver and glass products of the medieval Prikamie (by the example of the Lysvenskaya treasure)

Abstract

The chemical composition of a number of coins, items of funeral rites and jewelry made of silver and glass beads of the medieval Prikamye has been studied. A high fineness of silver and a slight admixture of copper, the use of silver and gold amalgam in the process of their manufacture, the sulfide-silver (acantite) composition of niello, silver soldering with a mixture of silver powder with coal-wood dust and, less often, tin were established. Glass beads were made from quartz sand, dolomitic limestone and desert plant ash using a dye (CuO) and an opacifier (SnO2).
