to revive Eastern iron mining in the face of competition from Minnesota, Crane took part in Thomas Edison's attempts to develop a magnetic ore beneficiation process. However, Edison's experiments proved uneconomical and the Edison Ore-Milling Company was a failure. In 1899, Crane Iron was sold to the Empire Steel and Iron Company, a conglomerate of Eastern and Southern iron furnaces. The Crane Works, as the company's plant was now known, last made iron in 1930, and the plant was torn down in 1932. Origins In 1837, the Yniscedwyn Works in Wales became the first ironworks in Britain to produce anthracite iron in commercial quantities, by use of the hot blast method. The works were owned by George Crane, and superintended by David Thomas. This discovery promised to provide a large market for anthracite, and the managers of the Lehigh Coal & Navigation Company wished to duplicate the process in the United States. After negotiations with Crane and Thomas, they were able to hire Thomas to emigrate and manage their proposed ironworks. The company was named in honor of Crane: it was organized on April 23, 1839 and incorporated on May 16, 1839, under a general act of the Pennsylvania Legislature. The LC&N supported the new company by granting them land and rights to water power (from the LC&N's canal) for their furnace. Early years Construction of the first furnace commenced about August 1, 1839, at Biery's Port, later Catasauqua. The ovens for the hot blast were coal-fired, and the blowing engine was driven by a waterwheel tapping the canal at Lock 36. The furnace was blown in on July 3, 1840 and the first four tons of iron produced July 4, 1840. It remained in blast until flooded by a January freshet in 1841, producing 1,080 tons of iron during that period. No. 2 Furnace was erected in 1842, using waste gas from the stack to heat the blast instead of coal-fired ovens. No. 3 was built in 1846, and Nos. 4 and 5 in 1849, as the iron business increased. The limestone flux for the furnaces was largely shipped from local quarries. A mixture of about 75% limonite and 25% magnetite ore was used to supply the furnace. Most of the limonite was mined locally: the first batch of ore smelted at the furnace was supplied by Henry Hoch's mine (also referred to as Rice's mine) in Schoenersville nearby,
