Not sure if this is the right place to post but it's my best guess.
Does anyone know of a site or source I can go to to figure out if there is lead or other chemicals in my dishes? I'm wondering if it's a given since they are antique. Do most dishes prior to a particular date contain lead? I hate to give up my collection of various pieces of blue willow but.... I just recently thought of this possibilitiy and can't find a good site to help me figure it out.
