[6] 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,[7] and in 1948 she opened Heath Ceramics in Sausalito.
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.
[9] As the volume of orders increased, Edith designed a Sausalito factory space with the architecture firm Marquis & Stoller, which was completed in 1959.
[12] With recessions, changes in taste, inexpensive imports, and the aging of Brian and Edith Heath, the company struggled in the 1990s.
A notable collaboration was with Alice Waters, founder and chef of Chez Panisse in Berkeley, California.
[19] Subsequent collaborations have included those with Natalie Chanin of Alabama Chanin (resulting in a line of hand-etched dinnerware at Heath, evoking the hand-stitching of Alabama Chanin linens),[20] and designers House Industries (resulting in a line of ceramic house numbers featuring typefaces by Richard Neutra and Charles Eames, and a line of clocks featuring House Industries typeface).
[21] Heath has also collaborated with Geoff McFetridge,[22] and Commune Design to create lines of limited edition pieces.
