Jacques and Dani Ruelland met at the École des Beaux-Arts in Paris, where Jacques was taking painting classes while Dani worked in a sculpture workshop. United by their shared interest in ceramics—which combined explorations of volume, material, and color—they began working together in 1950 in an external studio near the Beaux-Arts on rue de Buci, and in 1954 established their own workshop at number 10 on the same street.

The Ruellands’ early works had a utilitarian aspect and often featured highly stylized zoomorphic or anthropomorphic motifs. By 1955, their practice became more focused with the development of a unique clay mixed with manganese oxide. They successfully produced bottles, vases, lamp bases, and bowls in vivid, glossy colors such as turquoise, apple green, uranium orange, and golden yellow. These pieces, designed as cohesive sets, were not wheel-thrown but individually hand-modeled, ensuring subtle variations within each series.

From the 1960s onward, they began layering opaque and transparent glazes, ranging from deep black to soft beiges, jade greens, apple greens, and delicate pinks. As early as 1953, they exhibited at the Galerie du Siècle on Boulevard Saint-Germain. From 1959, they participated regularly in the Salon des Artistes Décorateurs and later exhibited internationally in the United States, Japan, New Caledonia, Germany, and Switzerland. In 1970, they left Paris and settled in Les Angles, near Avignon.
