How does one test for lead in pottery glazes?

Rating: 75

A solution is poured in the pottery, allowed to sit and then tested for any leached lead. In general, ceramic pieces that have a well-matured glassy appearance that is smooth and hard glossy looking are probably fired at high enough temperatures that the lead is stable. If the glaze is more of a matt finish, it could still be safe if fired at a high temperature. A kit for $29.99 is available to test for lead in pottery glazes.
