Introducing Range Kleen's new line of bakeware .... CeramaBake. This beautiful bright white bakeware - inside and out - uses an innovative ceramic technology coating that is not only easy-to-clean and stain-resistant, but it is also PTFE & PFOA FREE! Aluminized Steel construction offers durability and even heating. CeramaBake is suitable for ANY baking temperature and comes backed by a 5-Year Limited Household Warranty. Helpful Hint: Lower suggested baking temperatures by 25 degrees F and being checking doneness at lowest baking time. DO NOT STORE baked foods in the bakeware as this may encourage stainles over the lifetime of the bakeware. CeramaBake is a registered trademark of Range Kleen Manufacturing, Inc.
