 The first part of Mougin brothers' work is deeply connected to Art Nouveau, combining vegetable naturalism and female symbolism, crystallizations with glazes.Their first works are exhibited at the Universal Exhibition in Paris, 1900; but Joseph feels they still can improve their art, so he chooses to attend Sèvres manufacture as a student.Although not officially part of the Ecole de Nancy, the two brothers get very close to its members, especially with Victor Prouvé who they admire a lot and become great friends with.
