I believe the Pottery Barn website is a typo and should say “free” at the end of the phrase as they only list those items of concern in listings when it says the product is free of them.
But is obviously not accurate based on the results. When I called Fortessa they said that they don’t use lead in their processes, but that there may be low naturally occurring levels.
Yes – this is likely trace lead contamination in the substrate of the dish – tested through (likely) Lead-free clear glaze.

Do you have recommendations for everyday plates/dinnerware that are not glass? Is it okay to buy porcelain plates that have been lead tested and come back as safe? Or is zero lead preferred? What is your opinion on “stoneware” plates? Can stoneware contain lead as well?
Hello Tamara, I have same questions as the poster above. Would you please come back to this questions?
