Repoussé is a metalworking technique where a malleable metal is hammered from the reverse side to create a design in relief. This technique allows for intricate and detailed patterns to be formed on the surface of the metal. It has been used for centuries across various cultures to create decorative objects, jewelry, and architectural elements. Sterling silver, Hallmarks, official stamps indicating the purity of the metal and the maker, are crucial for authenticating sterling silver pieces and determining their origin and age. Decorative silver dishes, especially those from the Victorian and Edwardian eras, are highly sought after by collectors for their craftsmanship.
