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.
一种用于指示陶瓷制品上可浸出铅存在的快速颜色测试（QCT）被评估为一种筛选工具。对14套未装饰的釉面陶瓷杯和马克杯（共197件）进行了测试。QCT表明，在约2微克/毫升及以上的水平时，95%的杯和马克杯存在可浸出铅。QCT是一种用于检测铅的廉价且快速的定性测试，可使用便携式试剂盒进行。
