His rare American porcelain works are characterized by natural elements such as bees, maple seed pods, and special green crystal glazes. • Collaborations and later works by Milet: At the beginning of his career, he regularly collaborated with Félix-Optat Milet on intricate polychrome enameled stoneware. Later, he worked from Créteil in France, where he produced elegant pear-shaped porcelain vases.
