30R Hellenistic or Roman Ribbed bowl of the Allaire Collection of Glass

Date: Late First Century B.C. to Mid First Century A.D. Diameter: 13 cm


Remarks: This earlier Roman ribbed bowl was probably not made by the direct cast and slumping method.  It may have been formed from a thick round disk. 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. A small percentage occur in cobalt-blue or other colors. The size of the bowls and thickness of the ribs vary.
