I learned the ancient technique of chasing and repousse from Masters in Bulgaria and Italy. There are few techniques that offer such diversity of expression while still being relatively economical. Chasing is the opposite of 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 techniques of repoussé and chasing use  the placticity 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.
