Daum is a crystal studio based in Nancy, France, founded in 1878 by Jean Daum (1825–1885). His sons, Auguste Daum (1853–1909) and Antonin Daum (1864–1931), oversaw its growth during the burgeoning Art Nouveau period. Currently Daum is the only commercial crystal manufacturer employing the pâte de verre (glass paste) process for art glass and crystal sculptures, a technique in which crushed glass is packed into a refractory mould and then fused in a kiln.
During the Universal Exhibition of 1900 Daum was awarded a ‘Grand Prix’ medal. Daum glass became more elaborate, acid etching (by Jacques Gruber) was often combined with carving, enamelling and engraving on a single piece of glass to produce creative glass master-pieces. The most complicated creations also feature applied glass elements, such as handles and ornamental motifs in naturalistic forms. The Daum brothers quickly moved on to become one of the major forces in the Art Nouveau movement, seriously rivalling Gallé, so much so that when Émile Gallé died in 1904 they became the leaders in the field of decorative glass.
In 1906 Daum revived pâte de verre (glass paste), an ancient Egyptian method of glass casting, developing the method so that by the 1930s Daum's window panels used pâte de verre for richness instead of leaded or painted glass. Today Daum still used this method to produce their pieces.
Daum and Nancy (East of France)
Daum has always been linked with the famous City of Nancy  in the Eastern part of France.
Its main manufactures are in the East part of the downtown of Nancy and in a small village a few miles from the city of Nancy called Vannes-le-Châtel.
In the Region all the pieces are still handmade by hundreds of employees.
ART and Daum
Daum was one of the family at the beginning of Art Nouveau. Daum and Nancy are two inextricably linked names synonymous with one of France’s greatest glassworks. Established at the end of the 19th century, Daum’s renown was originally linked to the Ecole de Nancy  movement, burgeoning at around the same time. Longevity and creativity have been the company’s enduring watchwords and its production has always moved with the times, particularly in the art of pâte-de-cristal, a major contributing factor in terms of its worldwide reputation.
The Daum Collection at the Nancy Musée des Beaux-Arts (Fine Arts Museum) with more than 600 items on display, the Daum glasswork in the Nancy Fine Arts Museum is held up as a reference collection by the scientific community and the public alike. Indeed, it is fair to say that it has no equivalent in any French or foreign museum. The collection is of top-notch aesthetic and historic quality and documents the history of glass manufacturing since it began in the 1880s through the 1990s.
The new collection of Daum are not at the Museum but can been seen in the store Place Stanislas.
After this world known era of Art Nouveau, DAUM has worked with hundreds of artists and designers to update new collections.
