Working in lost casting: a wax model is enclosed in a plaster mold, this plaster mold is heated. The wax model becomes liquid and flows out of the plaster mold. This creates a cavity. This is then filled with hot liquid bronze. The wax model is lost during this process, hence the term “lost casting”
This is how a work of art is produced in “lost casting” in bronze:
- A wax model of the artwork is created by hand
- This wax model is cast in plaster
- The plaster mold is heated
- The wax model liquefies and the wax flows out of the mold.
- A cavity is created in the plaster mold
- This cavity is then filled with liquid bronze
- Once the plaster mold has cooled, it is smashed and the cast is then finely sanded and polished
- The wax model is lost in this work process, hence the term “lost cast”.
- Each piece is unique.
