How does the lost wax process work?

The lost wax process, or cire perdue, is a method for creating metal sculptures and objects. It begins with crafting a model in wax, which is then encased in a heat-resistant material, typically clay or plaster. Once the mold hardens, it is heated to melt and drain out the wax, leaving a hollow cavity. Molten metal is then poured into this cavity to create the final piece, after which the mold is broken away to reveal the finished sculpture.
