Answer:
The correct answer is A. (1) Lost wax; (2) casting.
Explanation:
Lost wax, or lost-wax casting, is a technique in which a sculpture is made as a duplicate of an original sculpture.
Although there are many different processes to cast a sculpture in lost wax, the principles remain the same:
- A model is made, often in clay or wax.
- A mould is made around the original piece.
- The mould is partially filled with wax to create a hollow copy of the original.
- A second mould, made with fire resistant materials, is created around the wax model.
- Liquid metal (often silver, gold, brass, or bronze) is poured into the mould.
- The wax evaporates, liquifies, or burns, leaving room for the metal to cast inside the mould.
- The mould is removed and the final piece is recovered.
