Chasing & repoussé
Is the process of forming a low relief into sheet metal. Chasing is performed on the front of the design giving the design sharp clarity and various texture. Repoussé is generally carried out on the back of the design where specific areas are pushed out providing the design with dimension and depth creating the low relief.
Depending on the complexity of the design the metal may be flipped from front to back several times to achieve the finished design.
The sheet metal is held in a pitch bowl, a shallow steel bowl filled with pine pitch which when heated becomes soft and tacky, conforming and holding the sheet metal. When the pitch cools to room temperature the work is fixed and the unique composition of the pitch allows for the sheet metal to be formed and sculpted creating one of a kind designs.
