The manufacture of an ancient silver bowl

An ancient silver bowl with a unique incurved rim (U.C.8955) reputed to stem from dynastic Egypt, earlier thought to have been manufactured by spinning, was examined and was replicated by the authors in copper by spinning and by hammering. Based on 1) the results of the replicated bowls, 2) the actual variation and surface finish of the antique bowl, and 3) an examination of the historical facts of metal working in dynastic Egypt, the authors suggest that the bowl was manufactured by hammering. This appears to support the contention of many investigators that spinning was not practiced in ancient Egypt and that it is a much more modern invention.
