After the Civil War the charcoal-fired furnace was owned by Clement Grubb's son-in-law, L. Heber Smith, a Civil War Colonel who married Clement's daughter Ella Jane Brooke Grubb in 1868. It passed through several hands before Smith took ownership, probably after the war and before his marriage to Ella Jane. It is likely that the Grubbs assisted with the furnace's major technological upgrade in 1889, when Ella Jane was an heiress to her father's sizable estate that year. The furnace continued in operation under Smith until it was "blown out" after his death in 1898 at the age of 61. The furnace was acquired by Bethlehem Steel, who deeded it to the Hay Creek Valley Historical Association in 1979. The ruins have been preserved and are open to visitors.
