About PW4
History
Zinc oxide came into use as a white in the 19th century, first in watercolor and later in oil, as a non-toxic alternative to lead white.
In mixes
A cool, transparent white that keeps tints clean and is good for glazes and scumbles. Conservators have linked zinc-rich films to brittleness and cracking over time, so many painters avoid it in lower layers.
Drying speed is typical for linseed oil; tubes ground in safflower or poppy oil, or with driers added, will differ. These are general notes on the pigment, not on any one brand.
