Related lead sulfochromate pigments are produced by the replacement of some chromate by sulfate, resulting in a mixed lead-chromate-sulfate compositions Pb(CrO 4) 1-x (SO 4) x. This replacement is possible because sulfate and chromate are isostructural.
Lead(II) chromate can be produced by treating sodium chromate with lead salts such as lead(II) nitrate or by combining lead(II) oxide with chromic acid. Related lead sulfochromate pigments are produced by the replacement of some chromate by sulfate, resulting in a mixed lead-chromate-sulfate compositions Pb(CrO 4) 1−x (SO 4) x. This ...
Chrome yellow or crocoite (PY34): lead chromate (PbCrO 4). Cobalt pigments. Aureolin or cobalt yellow (PY40): potassium cobaltinitrite (K 3 Co(NO 2) 6). Iron pigments. Yellow ochre (PY43): a naturally occurring clay of monohydrated ferric oxide (Fe 2 O 3 ·H 2 O). Lead pigments. Naples yellow (PY41). Lead-tin-yellow: PbSnO 4 or Pb(Sn,Si)O 3 ...
Lead white paint dries relatively quickly to form a strong, flexible paint film. Lead-based white is one of the oldest manufactured pigments. It was the only white pigment available to artists in appreciable quantities until the twentieth century, when zinc white and titanium white became available. [44]
Titian, Bacchus and Ariadne, 1523 Rembrandt van Rijn, Belshazzar's Feast, 1635 Johannes Vermeer, The Milkmaid, 1657-58.

Tarnished lead (left) and shiny lead (right) Compounds of lead exist with lead in two main oxidation states: +2 and +4. The former is more common. Inorganic lead(IV) compounds are typically strong oxidants or exist only in highly acidic solutions. [1] Red α-PbO and yellow β-PbO The mixed valence oxide Pb 3 O 4 Black PbO 2 which is a strong ...
