Osmond iron consisted of balls of wrought iron, produced by melting pig iron and catching the droplets on a staff, which was spun in front of a blast of air so as to expose as much of it as possible to the air and oxidise its carbon content.H. R. Schubert, History of the British Iron and Steel Industry from 450 BC to AD 1775 (Routledge and Kegan Paul, London 1957), 299–304. The resultant ball was often forged into bar iron in a hammer mill.
