RED-LEAD....
Red Lead is a bright red to orange-red powder, used lead
glass, and red pigments; a paint made with red lead is
commonly used to protect iron and steel from rusting.
Chemically, red lead is lead tetra oxide, Pb3O4, a
water-insoluble compound that is prepared by the oxidation
of metallic lead or of litharge (lead monoxide); the
commercial product sometimes contains litharge as an
impurity.
Red Lead primer is one of the oldest and most commonly used
anti-corrosion pigments applied to metal surfaces.
Orange-red in color, red lead forms the prime coat for most
of the largest bridges in the world. Red lead is also the
primer of choice for most of the intricate steel structures
of buildings built in the 20th century. Resistant to even
salt water, red lead was liberally applied to the hulls and
decks of millions of ships. Typically, 85% red lead (lead
concentration = 85%) was applied to these steel surfaces.
Later, red lead primers containing as much as 95% to 98%
lead were used
