Anotations

Scope note:

A bright white, permanent, opaque, nontoxic pigment made of zinc oxide and other components. Zinc white exists in various grades: white seal (>99% zinc oxide, but with poor covering power), green seal (> 99% zinc oxide with good covering power), red seal (slightly less pure, generally used for grounds), gold seal (also less pure, used for grounds), and gray seal (contains some metallic zinc). Zinc white pigment is used in many media, including pastels, watercolor, and goache.
