Abstract
A method is described for rapid, large scale, and specific identification of anglesite and cerussite, individually or in combination, with little possibility of interference from other minerals of from containers. Water free from lead salts, a 5 percent solution of acetic acid, a 5 percent solution of potassium iodide, and a few simple items of equipment are required. Different methods for applying the solutions, ranging from eye-droppers to two-gallon garden sprays, are described. If qualitative results are calibrated to assays, semi-quantitative field estimates of anglesite and cerussite are possible under a variety of conditions. A supplementary method for determining cerussite with 10 percent sodium sulfide solution is discussed briefly.
