Extracting Lead from Galena — Humanity's Oldest Smelted Metal
How to identify and smelt galena (PbS) to extract metallic lead. Galena is the primary ore of lead and has been smelted since approximately 6500 BCE in Anatolia, making lead one of the earliest metals worked by humans. This blueprint covers ore identification (cubic crystals, metallic luster, specific gravity 7.4-7.6), roasting to remove sulfur (PbS + O2 -> PbO + SO2), and carbon reduction of lead oxide to metallic lead. CRITICAL: Lead is a cumulative neurotoxin with no safe exposure level. Full protective equipment and ventilation are mandatory.
