Chromate Of Mercury

has been improperly classed as a red with vermilion, for though it is of

a bright ochrous red in powder, when ground it becomes a bright

ochre-orange, and affords with white very pure orange tints.

Nevertheless it is a bad pigment, since light soon changes it to a deep

russet colour, and foul air reduces it to extreme blackness.
