Abstract:
A quick color test (QCT) for indicating the presence of leachable Pb on ceramicware was evaluated as a screening tool. Fourteen sets of cups and mugs (197 pieces) of undecorated glazed ceramicware were tested. The QCT indicated the presence of leachable Pb on 95% of the cups and mugs at or above approximately 2 micrograms/mL. The QCT is an inexpensive and rapid qualitative test for Pb that can be conducted with a portable kit.
