Technical Observations: The patina is grayish brown with green corrosion and light brown encrustations. Numerous stress cracks are present, but it is otherwise intact. The bowl was formed by hammering a cast ingot. The ribs were formed by punching the metal out from the interior, probably against a surface with corresponding curvature. The bottoms of the ribs on the exterior of the bowl have U-shaped punch marks. Other finishing was also done by chasing from the exterior. The lines on the rim were made by engraving and not on a lathe.
