Scope and Content Reconstruction and section of blast furnace at Bonawe Ironworks, Bonawe, Strathclyde Bonawe Ironworks on the shore of Loch Etive was founded in 1752-3 by Richard Ford and Company as an offshoot of their works at Furness in England. It exploited local wood for smelting iron ore brought via the loch from Lancashire and Cumberland. The furnace produced pig-iron, so called because the molten iron was periodically run off through the tap-hole (16) into trenches in the sand bed that made a pattern that looked like a sow suckling her piglets (18). A charcoal-fuelled blast furnace is fed with limestone, charcoal and ore. Continuous blasts of air fuel the burning charcoal. The temperature reaches about 1200 (C. Impurities combined with limestone, or 'slag', floats to the top of the molten iron. Source: RCAHMS contribution to SCRAN.
