California Proposition 65 requires special product labeling for products containing certain chemicals known to the State of California to cause cancer, birth defects or other reproductive harm if the product will expose the consumer to such chemicals. Lead levels in these products comply with FDA standards.
California requires the following separate notice:
Prop 65 Warning for ceramic tableware marked with a yellow triangle on the packaging: "WARNING: Use of this tableware will expose you to lead, a chemical known to the State of California to cause birth defects or other reproductive harm."
Prop 65 Warning for decorated glassware items: "WARNING: The materials used as colored decorations on the exterior of this product contain lead, a chemical known to the State of California to cause birth defects or other reproductive harm."
Prop 65 Warning for all other identified products: This product contains lead, a chemical known to the State of California to cause cancer, birth defects, and other reproductive harm. Wash hands after handling.
In compliance to California's Prop 65, rather than do destructive testing on each product, a majority if not all ceramics are labeled.
Below are FDA and Prop 65 standards of lead in Tableware, as supplied by the California Department of Health Services ( http://www.dhs.ca.gov/dhildlead/tablewars/twregs.html).
