In 1947, Edith began to design and execute a limited hand-thrown production of her pottery and tableware with four apprentices in her own studio. Other retailers, such as Neiman Marcus, Marshall Field's, Bullocks, and the City of Paris began to order her tableware,Amos Klausner, “The Legacy of Edith Heath and Heath Ceramics” in Heath Ceramics: The Complexity of Simplicity, page 27 and in 1948 she opened Heath Ceramics in Sausalito. Edith designed the pieces and formulated the clays and glazes. Notably, she formulated the clay base for a single kiln-firing at a lower-than-normal temperature, one closer to that associated with earthenware bodies rather than stoneware. This reduced energy usage while producing a durable product.Amos Klausner, “The Legacy of Edith Heath and Heath Ceramics” in Heath Ceramics: The Complexity of Simplicity, page 25
