To identify Baccarat, look for markings on the bottom of the piece. The first Baccarat logo featured a wine glass, carafe and goblet with ‘BACCARAT FRANCE’ printed in a circle. Later pieces may only include the world ‘Baccarat’.
Some Baccarat paperweights that were made between 1846 and 1849 were stamped with the letter ‘B’ followed by a date, which represents the year the piece was made.
It is important to note that early 19th century Baccarat are not marked as the logo came along in the late 1800s, seeing as the two glass manufacturers Saint-Louis and Baccarat used to have a partnership and Baccarat started marking their pieces after Saint-Louis started its own production.
