Yes! Ceramic cups and mugs from Heath are completely safe. Phew!

Since every ceramic piece—from clay to kiln—is made in our factory right here in Sausalito, we know our materials and where they come from. Rest assured, we do not use lead or other toxins in our glazes, and our products undergo rigorous third-party testing to ensure that they not only meet but exceed both U.S. and California safety standards for food use.

Since our earliest days as a small business, Heath has always been committed to sustainable practices. Today, we’re proud to be a certified B-Corp.

Yes! Stoneware ceramics naturally retain heat well. Handcrafted ceramic mugs from Heath are great for coffee, tea, or hot chocolate, and each piece of drinkware beautifully complements our dinnerware and serveware sets.

Yes, ceramic cups from Heath are dishwasher safe with some considerations. We recommend using gentle detergents and running the dishwasher on a light cycle for the best results. While stoneware is more chip-resistant than bone china or porcelain, you’ll want to be sure not to overload the dishwasher to prevent pieces from touching. Avoid rinse aids, which may damage your stoneware’s glaze.

Yes, ceramic mugs and cups from Heath are microwave safe with some considerations. We caution against placing our mugs or cups in the microwave for extended periods of time. As a rule of thumb, avoid shocking the temperature of any ceramics from cold to hot – or vice versa. Stoneware naturally withstands heat, but sudden temperature changes crack your beloved Heath pieces.
