The company, well known for its mid-century modern ceramic tableware, including "Heathware," and architectural tiles, is still operating in Sausalito, California, after being founded in 1948.

[citation needed] In 1943, she studied eutectics, the science of mixing various metals with clay to create specific properties, with Willard Kahn through the University of California extension courses.

[4] Heath's continued experimentation led to her becoming an expert in how different clay types affected aesthetic qualities of her wares.

[8] Major retailers began to order tableware, which required Heath to develop ways to manufacture her pieces from her design rather than create them by hand.

Edith Heath's "Coupe" line remains in demand and has been in constant production since 1948, with periodic changes to the texture and color of the glazes.

The distinctive and modern curvilinear exterior facade is faced in 115,000 glazed tiles, in varying brown tones with an undulating surface, made by Edith Heath.

[6] Interested in making use of small clay leftovers and space in the kiln, Heath created a line of ceramic buttons.
