Lead is a naturally occurring bluish-gray metal found in small amounts in the earth's crust. Lead poisoning is the leading environmentally induced illness in children. At greatest risk are children under the age of six because they are undergoing rapid neurological and physical development. Lead and cadmium are still used in some ceramic dishes and while levels are regulated by the FDA and, more strictly, by California, you can't be assured your tableware is lead- and cadmium-free even if it meets California's Proposition 65 standards. However, most tableware doesn't pose a serious health risk.
Choose glass, stoneware, or ceramic dishware. Ceramic dishware labeled as meeting California’s Proposition 65 requirements leach less lead than those approved by the FDA and are preferable. Plain white dishes rarely contain lead.
