I bought the best ceramic soup bowl from the Chinese supermarket the other day. cute design, nice size, has a handle and plastic lid. but it has a sticker on it that says "Warning: Cancer and Reproductive Harm. www.P65Warnings.ca.gov"
the website is a clearinghouse of info about potentially toxic substances, but I can't find anything about carcinogenic dishware. can anyone tell me more? how likely is it that the ceramic is fine and the lid just isn't heat-safe?
