Abstract
A device for testing for the presence of lead on a painted surface includes a porous dauber formed from an absorbent sintered plastic. The dauber is preimpregnated with a powdered mixture containing rhodizonate dye which is activated by dipping the dauber in a small quantity of water. After activation, the dauber is rubbed on the surface and is then visually observed for a reaction with lead that may be in the surface. The device also includes an abrasive element that can be used to abrade the painted surface before contacting the same with the dauber.
