Jacobite glass: A 17th-century English drinking vessel used for toasting Prince Charles Edward Stuart ("Bonnie Prince Charlie"). The Jacobites were supporters of the exiled King James II, who abdicated in 1698, and of his descendents James Edward Stuart (the "Old Pr etender") and his son Charles Edward Stuart (the "Young Pretender"). Before the defeat of the Young Pretender in 1746, Jacobite glasses were usually engraved with the English rose, representing the Crown, and an optimistic motto such as "Redeat" ( Latin, "May he return"). After 1746, glasses at first bore cryptic symbols and messages, but later secrecy was abandoned. See also Williamite glass.

Japanese Glass: General term for glassware made in Japan since the mid-eighteenth century.

Jugendstil (German, "youth style"): See Art Nouveau.
