Furnace IndexFurnace HomeHome

Stewardson - Is along Mahoning Creek in Pine Township. It was built in 1851 by Stewardson and Laughlin. Intended to use coke it had little success at first but later was quite successful. It was 43 feet high with an 11 foot bosh and a capacity of 75 to 80 tons a week until it went out of blast sometime after 1880. There are coke ovens farther up the hill(s&t). We photographed this site. Part of the inner lining, portions of the outer walls, many loose stones and part of the retaining wall are visible. There are huge slag piles. (P)(V)(rp1978-2004)
