IUPAC name:	Lead carbonate
Layman's explanation:	The name cerussite came from the Latin word cerussa, which means white lead. It was written about as early as 400 B.C. by Greeks. Cerussite is an orthorhombic mineral, meaning its symmetry is has three unequal axes and have 90 degree angles to one another, and it is often found in upper oxidized portions of ore deposits. Although often colorless or white, due to the lead content, cerussite has a brilliant luster. This mineral is often found twinned, in which it appears as two crystals grown together instead of the normal one. It is an ore of lead and used as a mineral specimen.
