Repoussé is a decorative technique whereby three dimensional relief designs are formed by raising the metal from the reverse. This is accomplished using hand punches and hammers on metal that has been placed into a bed of something that will yield to pressure, such as pitch. The metal is periodically annealed to prevent it from breaking.
