eut compounds. 1t is claimed that
there is a partial union OF this pig
ment with the linseed oil but be-
Here thelo IS NO UNION other than
the mechanical II of enmeshing the
fine PARTICLES of lead in the hardening
film of oil. But this Is sufficient and
no better paint can be made than that
formed by the combination of white
lead and linseed oil. When | say
white lead, | mean PURE white lead
and il is much better to buy the
prepared lead ground in oil be-
cause the mixing is partly done
and that is no small matter. There
are several standard brands of pure
lead on the market. Those best
known are the Southern, Carriers,
Collier, Eagle, and Red Seal. The
two best known brands in this sec
ton are the Southern Dutch boy
and Carriers. These two leads. are
j representatives of quite different
processes of manufacture but both
are fine products. Both AREAS near
ly pure, as it is possible to make
them and they can not be excelled
for paint purposes. Some painters
claim that Carter's covers more sur
face. others that Southern lead works
better, but the difference, if any,
is not great and the house owner
can blu. either with the assurance
that il is the best the market af-
fords. They are absolutely stand
ard and dependable.
There are many ad%ulterated leads
ON the market, and the amount of
adulteration runs anywhere from one
fourth 10 three-fourths. These are
the Just as good" kinds that are
offered. Thousands of tons of adul-
terated leads are sold every year.
Some dealers handle these adultera-
ted leads and perhaps they are some
times sold as pure lead but | do not
think much of this large output is
sold by retailers direct to customers
Some of it goes into mixed paints,
but most of 1t is used by painters
and contractors and that is likely to
continue as long as the property own
er is so indifferent that he makes
his contract for painting to cover the
material as well as the labor.
The a%dulterant is nearly always
Barytes, sometimes mineral white
is added,
Zinc-As an all round pigment Zinc
does not equal white lead, but it
has some advantages over lead. 1t
is whittier thar lead and has greater
+, covering power. In this respect ten
parts of zinc equals about thirteen
parts of lead. 1t hasn't the per-
, manancy of lead and is more expen-

Zine that is used but the Commercial
zinc contains some zinc carbonate
; also. 1t is much used for interior
white jobs because of its whiteness
! and because it does not turn yellow
/, in dark places as lead does. 1t is
, not very much used alone, uually
/, turers claim that it makes a better
, paint used with lead, for outside
r work, than lead alone. 1t does
make paint go farther, but | doubt
S if it makes it any better for outside
j, use from the stand point of dura-
4 bility. The old time job done with
S lead, before painters thought zinc
|, was safe to use for III side work,
3 was equal to anything done in more
t recent years.
Barytes-the native baryta is the
t sulphate of Barium. Called also
) Heavy Spar" and this ground fine,
makes "Baryta White" But the
artificial sulphate compounded from
the native carbonate CWitherate) is
what is usually used as a pigment.
This is nearly pure Barium sulphate
and is known as Fixed White or
Charlton White" or "Silicate white"
