Reduction

Definition

Reduction refers to the chemical process of removing oxygen from metal ores or gaining electrons during the extraction of metals, ultimately converting them into a purer metallic form. This process is crucial in metallurgy, particularly in the transition from bronze to iron technology, as it signifies a shift in techniques and materials used for metalworking, resulting in the development of stronger and more versatile iron tools and weapons.
