Repoussé or repoussage is a metalworking technique in which a malleable metal is ornamented or shaped by hammering from the reverse side. 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.
While repoussé is used to work on the reverse of the metal to form a raised design on the front, chasing is used to refine the design on the front of the work by sinking the metal. The term chasing is derived from the word "chase", which refers to a groove, furrow, channel or indentation.
The techniques of repoussé and chasing utilize the plasticity of metal, forming shapes by degrees. There is no loss of metal in the process, as it is stretched locally and the surface remains continuous. The process is relatively slow, but a maximum of form is achieved, with one continuous surface of sheet metal of essentially the same thickness. Direct contact of the tools used is usually visible in the result, a condition not always apparent in other techniques, where all evidence of the working method is eliminated.
The Peddinghaus hammers listed below are made in Germany for working jewelers and metalsmiths. Heads are forged for superior durability. All meet ISO and DIN standards. They are made of high grade steel and are the most reliable hammers you'll find anywhere. All hammers feature finely balanced heads for an easy accurate swing. Handles are smooth and of ash or hickory for a comfortable grip.
