The kanji 銑 is a phono-semantic compound (形声文字 - けいせいもじ). ⚫︎ The left side is 金 (かね, kin, gold/metal), indicating the material itself. ⚫︎ The right side is 先 (せん, sen, before/ahead), suggesting the initial processing stage or the "first" form of the metal. ⚫︎ Thus, it combines the meaning of metal with an indication of its initial state or processing, creating the meaning "pig iron." The character visually and conceptually links the material (metal) with the process that creates it, linking it to the raw product.
