A person or machine that makes or shapes cores, especially the sand cores used in casting metal or glass.
From core + maker (one who makes), from Old Norse kjarnir + maker. Used in manufacturing and industrial trades.
Medieval metalworkers were early coremakers, creating sand cores inside molds to form hollow metal parts—without this technique, we couldn't have made bells, cannons, or complex engine blocks.
