Unidentified, Patella Cup, 1st century or 2nd century A.D., glass/polychromed, Smithsonian American Art Museum, Gift of John Gellatly, 19220.127.116.11
Most of the glass vessels in this case date from the first century BC to the fourth century AD. Early glass vessels were made in the Middle East and Egypt using the core-forming technique, in which molten glass was poured over a clay core and decorated with threads of colored glass. During the first century AD, Rome became the center of glassmaking, and the invention of blown glass led to new methods, including free-blown glass, which could be decorated by pinching, rolling, or dragging the surface, and mold-blown glass, in which the molten glass was blown into a terra-cotta mold.
