Description
A grayish-white, crystalline mineral called Cerussite that is one of the primary types of [[lead] ore. Cerussite is mined in Australia, Europe, and the U.S.(Colorado, Arizona, New Mexico, Idaho). Cerussite can be formed by the action of ground Water on Galena (Lead sulfide) ore. Although basic lead carbonate has been used as a white pigment since ancient times, it was made synthetically and not obtained from the naturally occurring cerussite ore. In fact, cerussite has rarely been used as a white pigment although it is occasionally found as an impurity in basic lead carbonate (Gettens, Kuhn and Chase 1993).
