The older brother of Clément Massier, Delphin Massier had inherited his share of the family ceramics business upon the death of their father Jacques in 1871. When Clément relocated to one of the family properties in southern Vallauris, Delphin moved elsewhere in Vallauris, leaving Jacques's factory to a second cousin, Jean Baptiste Massier (son of Jerome Massier). There he specialized in polychrome enameled faience destined for home and garden. During the Art Nouveau years, Delphin mastered the metallic luster glazing as practiced by Clément. In the firing his vessels often obtained a brilliant iridescence.
