Made from Basic Lead Carbonate with a small percentage of Zinc White added to improve the consistency and to add whiteness to the paint film.  Preferred by some artists as a traditional lead white because it is ground in Linseed Oil.  It may be used throughout the painting.  It has a fast drying rate and benefits mixtures by its durable, flexible nature.  Linseed Oil whites will show greater yellowing than Safflower whites.  The latter are recommended for final white highlights.  Foundation White is recommended for underpainting and the development of strong textural effects and heavy paint applications.
