lost-wax

The term 'lost-wax' is a modern English compound that transparently describes a key step in the ancient 'cire perdue' casting process. The first element, 'lost', derives from an Old English verb meaning to perish or be destroyed, here used in its participial form to indicate the fate of the wax model. The second element, 'wax', comes from the Old English word for the malleable substance produced by bees. The compound's logic is entirely descriptive: it names the technique by its defining action—the wax model is intentionally 'lost' (melted out) to create the mold. This English term is a calque, or loan translation, of the French 'cire perdue', which carries the identical literal meaning.
