Cl��ment's second cousin, Jean Baptiste introduced a particularly sculptural quality to the family's pots, which frequently featured the slender and graceful shape of American dancer Lo?e Fuller. In the Netherlands, the Rozenburg factory contributed major suggestions in the shapes of Art Nouveau pottery. There, in 1899, Jurriaan Kok and M. N. Engelden announced the astounding "eggshell porcelain," really a very thin and light-weight earthenware, reinforced by glazing on the inside and outside. This fine and delicate ceramic featured tricky
and gorgeous images of vegetation, bugs, and birds painted by Samuel Schellink and R. Sterken. Before that, architect, potter, and textile designer
Theodoor Colenbrander left Rozenburg to form his own Gouda Ceramic Factory. He found the Art Nouveau style especially suited for his tastes, as he favourite bold colors and shapes inspired by Javanese batik ware.
