I read an article about lead being in the pattern and glaze of the dishes. The Corelle website even suggests that vintage Corelle ware be use for decorative use only. I've been using Corelle for years. Makes me heartsick. Those made after 2003 and the plain white earlier versions are lead free. I replaced my vintage patterned plates. I don't think I should donate them so what to do with them? I guess toss them?
