The act of engraving, carving, or chasing (working) designs into metal or another surface.
From Latin 'celare' meaning to engrave or carve, possibly cognate with 'celere' (to cut or engrave), though the connection to 'hide' may be semantic drift.
Celature is what Renaissance goldsmiths did when they carved intricate designs into precious metals—the word is so specialized that metalworkers might use it once in a lifetime.
