Is ceramic pottery safe?
Pottery items with decorative and colorful, shiny pieces on the outside of the food area are generally safe. The plain white area usually does not have lead glazing. Avoid serving acidic foods on a lead glazed dish or bowl. Acid speeds up leaching which means that lead will quickly contaminate the food.

Does ceramic cookware contain lead?
Although the ceramic material itself did not contain lead, the glaze covering the inner and outer surfaces of the cookware and mug was 17% lead by weight.
How do you know if ceramics are food safe?
To test a glaze’s acid resistance, squeeze a lemon wedge onto a horizontal, glazed surface. Changes in the glaze color indicate that acids from foods can leach materials from the glaze, and that it is not food safe.
Do ceramic glazes go bad?
Glazes do not ‘go bad’ with age but, because different ingredients tend to come out of suspension at different rates, it is critical that the batch or bottle be mixed thoroughly before each application. Single firing (glaze applied to greenware) is not recommended with today’s glazes.
How do you test for lead in ceramics?
Test the pottery. Consumers can buy lead-testing kits in hardware stores or online. The kits contain swabs with instructions on proper use of the swabs and reading of the results. In most cases, the consumer will rub the swab on the food-contacting surface of the pottery.
