If ceramics are baked for long enough at hot enough temperatures, they may still be safe, but if not, the lead can leach into food and cause lead poisoning. Acidic food or drink is especially likely to cause lead to leach out of ceramics, unfortunately for coffee drinkers with favorite earthenware mugs.
