British and Tasmanian Charcoal Iron Company - Wikipedia

The price of imported pig-iron increased, from £4 10s per ton in 1870 to £9 per ton in 1873 greatly advantaging locally manufactured iron. However, this high price did not last long, as iron-making capacity increased and pig-iron was once again imported cheaply as ballast in sailing ships returning from England to Australia.

Medieval Technology and American History - In-Depth …

Blacksmiths preferred working with charcoal-fueled, blast furnace bar iron and even modern steel works liked to blend it in alloys for special qualities. Old fashioned ironworks operators persisted and the Curtins of Centre County, Pennsylvania, unwisely built one of the last charcoal furnaces in 1848 and operated it until it burned down in 1921 excepting for a ten-year span from 1889 to 1900.
