Repoussé or repoussage (French pronunciation: [ʁəpuse]; [ʁəpusaʒ] respectively) is a metalworking technique in which a malleable metal is ornamented or shaped by hammering from the reverse side to create a design in low relief.
There are few techniques that offer such diversity of expression while still being relatively economical. Chasing is the opposite technique to repoussé, and the two are used in conjunction to create a finished piece. It is also known as embossing.
