ABSTRACT:
A color test is presented for the purpose of quickly identifying glazed ceramic and/or enameled metal ware which releases excessive Pb. Citric acid solution on filter paper is used to extract Pb from the ware and a Pb sensitive chromogen indicates the presence of Pb on the paper. The quick color test takes approximately 30 minutes and is useful for screening ware for testing by the 24 hour AOAC/ASTM method.
