White lead is the chemical compound (2PbCO3·Pb(OH)2). It is a complex chemical compound, containing both a carbonate and a hydroxide portion. White lead occurs naturally as a mineral, in which context it is known as hydrocerussite, a hydrate of cerussite. It was formerly used as an ingredient for lead paint and a cosmetic called Venetian Ceruse, because its opaque quality and the satiny smooth mixture it made with driable oils it made a good pigment. However, it tended to cause lead poisoning, and its use has been banned in most countries.
White lead compounds were also used as lubricants for bearings and in machine shops, especially between work being turned in a lathe and a dead center.

—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“I didn’t lead a very wise life, myself, but it was a full one and a grown-up one. You come of age very quickly through shipwreck and disaster.”
