Zinc White, or Zinc Oxide, is an artificial mineral pigment that was first produced in France in the late 18th century. Although, its use in commercial watercolours as Chinese White, pre-dates its inclusion in oil painting.
It is a semi-opaque, lightfast pigment, which dries very slowly in oil. Of all white pigments, it produces the most brittle paint film, so is not recommended in large quantities for impasto techniques. However, it is a good addition to a palette which requires a less overwhelming white than Titanium White.
