What does indurating mean?
Indurating means making something hard or becoming hard, a process commonly associated with heat, pressure, chemical reactions, or the passage of time. In technical writing, it can describe clay, minerals, metals, or other materials becoming rigid or stone-like. Figuratively, it describes the development of a stubborn or resistant attitude, often in people or institutions. The word is more formal and specialized than the everyday verb “harden,” and its passive or adjectival use, “indurated,” is especially common in descriptions of material properties and geological formations. Its historical roots connect the physical idea of hardness with figurative ideas of endurance and unyielding character.
