Is it safe to use dinner plates with worn off glaze?

Using dinner plates with worn-off glaze can pose health risks, particularly if the plates are made of materials that may leach harmful substances, such as lead or cadmium, into food. When the glaze is damaged, it may no longer provide a protective barrier. It's best to replace such plates to ensure food safety. If you are unsure about the safety of your dinnerware, consider consulting manufacturer guidelines or testing for lead content.
