Lead exposure from routine consumption of coffee and tea from ceramic mugs
My wife does pottery, and makes her own glazes. This is a major concern for potters, and you usually won't see a professional or semi-professional potter use lead in their glazes...<p>Of course, if you're buying on Amazon, who knows.. but you are very, very unlikely to have this problem with people who make pottery for a living (like local artists, or reputable Etsy shops)..
