Tin (Sn)
Tin may seem old-fashioned, but it plays some surprising roles in the world economy - from the glue that holds our electronic world together, to a revolution in glass-making.
Tin may seem old-fashioned, but it plays some surprisingly important roles in the modern economy. Presenter Justin Rowlatt meets our favourite chemist Andrea Sella of UCL at Pewters' Hall in London to discover the unique properties of the metal that sparked the Bronze Age.
He discovers the metal's role in plastics and electronics, and visits the giant Pilkington glass factory to find out how tin revolutionised the glass-making industry. And he meets two very venerable tin chemists, Alwyn Davies and Ted Fletcher.
