Retrospective review of development of brazing technique in manufacturing bronze, gold and silver items by the ancient and medieval craftsmen is given. Technology of brazing the intricate tin items is described. It is noted that the heat source was hearth furnaces with an air blowing through a tube, and the composition of fluxes included metallic powders of metals, carbonates and nitrides. Composition of brazing alloys was selected from the condition of a minimum temperature of eutectic transformation and similar color and glitter as that of the metal brazed.
Keywords: history of technology, technology of brazing, heat sources, fluxes, brazing alloys, brazed items
