Lead carbonate as a protective surface oxide; almost impossible to find today; recurs in §11.p2 in the context of Tom's eighty-five-year-old house's window flats.
In the old days, the gas tank in automobiles was made out of steel. But steel has lousy corrosion resistance, and if there's anything you don't want leaking out of your automobile, it's gasoline — tends to start fires. So they had terne-coated plate. Terne plate is almost impossible to find today. I don't even know if there's any steel company still making it. It's lead-coated steel. You wouldn't use zinc-coated steel, because in ten years that zinc is going to be completely consumed.
