A. Hall and Sons Terra Cotta:

View of Supreme Court Building from United States Capitol dome. Atlantic Terra Cotta created the terra cotta roof for the building housing the nation’s highest court.

A. Hall and Sons Terra Cotta was founded in 1846 in Perth Amboy, New Jersey^[1] due to Perth Amboy's rich supplies of clay. It was one of the first successful terra cotta plants in the United States.^[2] Originally, the manufactory produced porcelain and household wares but transitioned to terra cotta items as time progressed. The company, always located at 59 Buckingham Avenue, changed its name to the Perth Amboy Terra Cotta Company and then to Atlantic Terra Cotta^[2] which, as the preeminent terra cotta producer in the United States, went on to produce in its kilns the terra cotta for such notable buildings as the United States Supreme Court and the Philadelphia Museum of Art.^[3]
