Since the 1950s, ancient goldsmith techniques have been revived in the ZOLOTAS ateliers, such as the art of hand-hammering, which is considered the technique of Hephaestus, mainly used on hand shaped golden jewels. The goldsmith artist places the metal onto a smooth surface and then "beats" it with a small hammer with a rounded edge until the rippled effect is created. The technique of granulation, in which small spheres of gold are fused onto metal surfaces creating beautiful patterns, and the technique of filigree, wherein fine wires of gold are woven together, giving a greater volume to jewels, are applied in a modern expressive way.
