Therm-o-Rock Buildings (Wightman Glass Factory Buildings)

Remnants of the Pittsburgh region's enormous glass industry are rapidly disappearing, which makes the three remaining Wightman Glass factory buildings in New Eagle, the small town north of Monongahela, a rare find. They lie between the former Pittsburgh, Virginia and Charleston Railroad (PVCRR) tracks and the Monongahela River. The largest brick building is an enormous gable-roofed structure with a gabled monitor at the ridgeline. Corbeling along the cornice of the monitor's gable end distinguishes a circular window vent, with three elongated rectangular windows below. A second brick, gable-roofed building has corbeling at the cornice line, gable ends, and chimney. The tiny office building looks like a train station, although lacking the characteristic deep overhanging eaves. Its hipped roof is broken by large double-windowed dormers. The first story has wide paired windows and a handsome central door with sidelights and transom facing the railroad tracks. Therm-o-Rock has been combining and packaging organic additives and mineral aggregates and powders here since 1948.
