Anotations

Scope note:

A synthetic, permanent, stable white pigment prepared from precipitated barium sulfate (barite) since ca.1820s. The pure white powder is transparent when used as a filler or base for lake pigments. The reproducible whiteness of high purity led to its use in the standard white tiles for reflectance spectrophotometry.
