Productivity Growth in Obsolescence: Charcoal Iron Revisited

The technology of charcoal iron manufacture in late nineteenth-century Canada is examined in this paper. Use of a super-heated and hard-driven furnace blast contributed to a resurgence of production after 1890. A lag in the diffusion of these techniques is explained by the small size of the Canadian market. Contrasts are noted with charcoal iron smelting in several regions of the United States.
