A wax cast of each original sculpture is produced from the mold. At this stage of the process any last minute changes can be made of the original and final approval is given by the artist before the fabrication begins. Lost wax bronze casting dates back over 6,000 years. It is a complex and time consuming process but the result is an original, permanent piece of art. The wax cast is dipped repeatedly in a ceramic mixture called “slurry”, and re-enforced to create a strong ceramic shell inside and outside the entire piece. The ceramic shell is then fired and the wax melts out leaving an empty cavity for the bronze. This is the “lost wax”.
