Lowmoor Iron

—A very good quality of iron made at Lowmoor in Yorkshire. Since the permeability of different quale ities of iron varies greatly too great care cannot be exercised in its selection. Ewing has succeeded in forcing 45,350 lines of force per square centimeter through a sample of Lowmoor iron. To obtain this a magnetising force of H = 24,500 had to be employed. The Yorkshire wrought irons are nearly pure, on account of the care taken in their manufacture, the iron being refined as well as puddled. An additional circumstance contributing to their high quality is the entire absence of sulphur from the fuel used in the operations. Lowmoor iron is specified wherever a piece has to stand much working in the fire, or wherever absolute soundne is a nece ity.
