Lead from Galena

Lead is a soft, malleable and heavy post-transition metal with a bluish-white colour after being freshly cut, but soon tarnishes when exposed to air. It has a shiny chrome-silver lustre when melted into a liquid and is also the heaviest non-radioactive element. Lead is used in building construction, lead-acid batteries, bullets and shot, weights, as part of solders, pewters, fusible alloys, and as a radiation shield.

Circa 9,000 BCE in the Middle East.

DISCOVERY
