The ribs were formed hot with a pincer tool and then the disk was slumped into a bowl shape. The process is described in this link Ribbed Bowls and their Manufacture by Mark Taylor and David Hill. It is a class of bowls from the from the Eastern Mediterranean area with short, close-set ribs concentrated around the middle of the body. For the most part, such bowls are naturally colored, either bluish-green or light green, or intentionally decolorized. Small percentage occurs in cobalt-blue or other colors. The size of the bowls and thickness of the ribs vary.
