WHY WHITE LEAD HELPS PAINT " W O R K " EASILY
You've noticed how paints
with a high lead content
flow readily . . . level off
smoothly . . . pass all tests
for ease of brushing with
flying colors.

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.

This is not just a play on words. It is an honest question, the answer to which may be highly illuminating to you:
J B So great has been the improvemeat in color o f basic carbonate white lead in recent years that to
day this pigment can be had with a dry brightness o f 96%.
As you need not be told, that's really white. And, ex pressed in terms of paint-making, it means that you can obtain the required whiteness in your product and still have the advantages of white lead's proved durability and other desirable qualities.
We offer you five basic carbonate white leads, ranging from a low oil absorption type to one providing extrahigh hiding and paint consistency. Thus you can select the particular white lead best suited to your purpose.

reached sooner--and costs kept down.
And another thing: White lead today comes packed in
easy-to-heft 50-lb. bags --a Dutch Boy innovation which makes paint-making easier.
Remember, too, white lead adds the very qualities most desired in paint--better adhesion and drying, greater ease in brushing, more satisfactory leveling and flow-- plus proved durability.
Below are described the five Dutch Boy Basic Carbo
nate White Leads. They range from a low oil absorption type to one with extra-high hiding and paint thickening power. Among them there is a lead exactly suited to every need.
