Less Known As English Red Prussian Red And Scarlet Ochre True


Venetian red, that is, the red of the Venetians, was probably brought

from India, and similar to our modern Indian red. The Venetian red of

the present day, however, is an artificial product, containing no earthy

base, and therefore improperly classed among the ochres. It is prepared

by calcining sulphate of iron, to which a little nitre may be

advantageously added. The result is a peroxide of iron, resembling light

, but more powerful, and of a more scarlet hue. It is very permanent,

but being a purely iron pigment, should be cautiously employed with

colours affected by that metal. Though not bright, its tints are clear,

and it mixes and works kindly with cobalt or French blue, affording fine

pearly grays. Heightened by madder lake, it furnishes a glowing red,

very useful in some descriptions of skies; and saddened by black, it

gives low toned reds of good quality for buildings. With white it

produces carnation tints nearly approaching to nature, and much employed

by Titian, Vandyke, and others. Compounded with aureolin, Venetian red

yields a clear orange of considerable transparency.
