Photomicrograph showing formations o f lead soaps (Magnification 460X) The reason is this: Basic carbonate white lead and oil have a strong attraction for each other. A reaction takes place between the vehicle and the surface of the pigment particles. This reaction --commonly known as the formation of lead soaps --facilitates flow, promotes brushability. Improvement in working qualities is but one of the many desirable properties white lead imparts to paint. Others are better adhesion, more thorough drying--plus proved durability." Check over the five basic carbonate white leads the Dutch Boy offers. They range from a low oil absorption type to one with extra-high hiding and paint thickening power. Among them you will find a lead exactly suited to your needs. BOY WHITE LEADS 111 -- Extra-high hiding and paint consistency. 3 3 3 -- High hiding and paint consistency, but less than 111. H .T . S . -- Medium-high hiding and paint consistency. C a r te r -- Medium-low oil absorption white lead, made by the Carter Process. D utch -- Low oil absorption white lead, made by the Dutch Process.
