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.

Famous quotes containing the words white and/or lead:
“Would you ascend to Heaven and bodiless dwell?
Or take your bodies honorless to Hell?
In Heaven you have heard no marriage is,
No white flesh tinder to your lecheries,”
—John Crowe Ransom (1888–1974)
“The only ways of enquiry that lead to knowledge ... the one way assuming that being is and that it is impossible for it not to be, is the trustworthy path, for truth attends it. The Other, that non-being is and that it necessarily is, I call a wholly incredible course, since thou canst not recognize not-being ... nor couldst thou speak of it, for though and being are the same things.”
—Parmenides (c. 515–480 B.C.)
