The Process
All pieces are created using the lost wax casting technique in which a design is carved out of wax and a mold is made from the wax model. Once the mold is ready, the wax melts out of the mold and a metal is injected into the mold to create a metal copy of the wax design. Molds can even be created around organic material if it is sturdy enough to withstand the process.
The image above shows a before and after comparison of the Ravenna cuff. First, made in wax and Ravenna grass, the wax model is then cast into bronze.
