This vessel features, below the handle, an appliqué with the mask of a bacchant (a follower of Bacchus, the god of wine). Two methods of forming and attaching appliqués were employed in Europe during and after the Renaissance, and they probably were also used in Roman times. In the first method, the glassmaker slightly overfills a mold with molten glass. He then reheats the vessel and presses it against the excess glass. The glasses fuse, and the appliqué, now attached to the vessel, is withdrawn from the mold. The second method involves applying a blob of molten glass to the vessel and impressing it with a stamp. The larger the amount of molten glass, the greater the extent to which it softens and sometimes distorts the wall to which it is attached. For this reason, larger appliqués are usually molded and attached to the vessel after much of their heat has dissipated, while smaller appliqués are stamped.
