Zinc White: The most transparent white, Zinc is recommended for glazing, scumbling and alla prima painting. Compared with all other whites, Zinc White has less hiding power. Zinc White dries slowly, so painters who want to paint wet into wet over a long time will find it useful. Because it’s brittle, painters should not consider it as a general painting white unless painting on panel.
