There was a thread not too long ago on this topic. I'm starting a new thread as I didn't want this to get buried in it. I just came across this and I think it will be of interest. The main article has to do with lead in many slow cookers, and in the article is a link to a PDF file that gives the lead results for many popular dinnerware sets. The Corelle, BTW came out safe, while the Gibson dinnerware tested high for lead.
