Which metallurgical process used in Ancient Mesopotamia contributed primarily to the increased durability of bronze tools and weapons?

💡 Explanation

When bronze tools were quenched (rapidly cooled), the metal experienced increased hardness via martensite transformation. Then low-temperature tempering reduces brittleness, creating more durable cutting edges. Therefore quenching and tempering provided superior durability, rather than cold working, case hardening, or annealing, each offering different and often less desirable changes.
