Lead is a good example of a metal that was used for many things over centuries--in water pipes, paints, on roofs, and in leaded petrol, for example--but was superseded as scientists discovered "new" metals, and because its toxicity became a problem. It was originally an important element in pewter utensils, alloyed with tin; it made the tin easier to work. But it is no longer allowed in paints, pewter, or petrol because it is poisonous, and so its importance has declined. In this article, the author follows his personal family history in the lead-mining industry and discusses how the industry worked and why it ultimately went into decline.
