Etymology

The term "cast-iron" combines "cast," derived from Old Norse kasta (to throw or pour), referring to the process of shaping metal by pouring it into molds, and "iron," from Old English īsern (the durable metal). Historically, cast iron became prominent in the 18th century for its strength and moldability. The figurative sense ("unyielding") emerged in the 19th century, likening the material's hardness to stubbornness or resilience.
