Final answer:
The lost-wax casting process described is used in the creation of b. sculptures, whereby a model is made in clay, covered in wax, and molten metal is poured into the mold left after the wax is melted out.
Step-by-step explanation:
The process described in the question pertains to the lost-wax casting technique, which is used in the creation of sculpture. This ancient method involves creating a clay model of the desired statue, which is then covered in a second mold constructed in parts, allowing it to be removed easily. Once the second layer is removed, it is filled with wax and another layer of clay is applied. The mold is heated to melt out the wax, leaving a hollow cavity. Molten metal is poured into this cavity, creating the sculpture. After cooling and setting, the molds are broken apart and the metal sculpture is polished and assembled, if needed. Large sculptures may be created in pieces and welded together. This process allows only for a unique, one-of-a-kind artwork since the mold is destroyed during the process.
