Lead Ore

The material. When the Romans conquered Britain in 43 AD they discovered rich deposits of lead ore and started a mining and refining industry that was to continue for 1,000 years (the symbol for lead—Pb—derives from its Latin name: Plumbum).They used it for pipes, cisterns, and roofs—this last a use that continues to the present day.
