Repoussé is a metalworking technique that involves shaping metal by hammering it from the reverse side. This process creates a raised design on the front surface, allowing for intricate patterns and textures. Artisans often use materials like copper, silver, or bronze to achieve detailed effects. The technique has been used for centuries in various cultures, including ancient Egypt and Greece. Repoussé is commonly found in decorative arts, such as jewelry, sculptures, and architectural elements. It requires skill and precision, making it a valued craft among metalworkers and artists.
