Zinc White began to appear in addition to Flake White on artists’ palettes in the early 19th century.  Zinc White dries to a cold white appearance and is particularly suitable for mixtures with cool colours.  It is very useful for glazing and scumbling techniques, as it does not overpower other hues.  Though a dried film of Zinc White is relatively hard and brittle, this can be lessened by the addition of a small amount of Thickened Linseed Oil or Stand Oil.  The use of Safflower Oil reduces the tendency to yellow, common in whites ground in Linseed Oil.
