Jean-Baptiste DESVIGNES, (1786-1826), master of opaline decoration. The opaline, is a term created in its current meaning in 1907. It designates any white or variously coloured opaque vitreous substance with sometimes iridescent reflections. An opaline is a glass or crystal made either opaque by the addition of tin oxide, or opalescent by the presence of bone or horn ashes. This term is also used to designate the type of objects made in the 19th century. Opaline glasses were invented in the 16th and 18th centuries in an attempt to imitate Chinese porcelain.
Under Charles X, the colours became more intense, and pink was obtained by adding gold salts. From 1840 onwards, glass was no longer coloured but doubled. The factories of de Baccarat, Le Creusot and Saint-Louis will become the main production centres.
If many glassmakers remain anonymous, this is not the case of Jean-Baptiste Desvignes (1786-1826) who became famous for his decoration on opaline and his qualities as a gilder: he had invented a process of painting, gilding and engraving on glass which he deposited in 1817. He is at the origin of the decorations of our flasks.
