In the Maker Shed: Detection of lead paint test kit

The Detection of lead paint test kit provides the equipment and reagents you need to perform reliable multi-step laboratory tests for detecting lead content in paints. The sulfide test, a sensitive preliminary screening test, quickly identifies paint samples that may contain lead (but may instead contain only traces of cobalt or other innocuous metals that yield a false positive with the sulfide test). Samples that test tentatively positive with sulfide reagent can subsequently be subjected to confirmatory tests with chromate and iodide reagents, each of which produces a characteristic precipitate in the presence of lead.
