Lead Sheet Cast on a Tilted Iron Plate, Ure 1839
Thin lead sheet can be cast without rolling. Andrew Ure (1839) describes the white-lead works: melted lead is poured on an iron plate over the pot, and as soon as its surface begins to set the plate is tipped, so the still-liquid lead runs back and leaves a thin sheet that lifts off like paper. Their sheets were 1/24 inch thick or less.
The picture: our diagram, the plate tipped over the pot as the liquid runs off.
