Tarix
Metallic lead beads dating back to 6400 BC have been found in Çatalhöyük in modern-day Turkey.
The Romans also used lead in molten form to secure iron pins that held together large limestone blocks in certain monumental buildings.
In alchemy, lead was thought to be the oldest metal and was associated with the planet Saturn.
