Inc menStruum 10 supposed to be made
up of linseed oil ,and the necessary
amount of turpentine with possibly the
addition of Japan driers. The addition
OF any other constituent, or constit,I-
mixed paints, in any considerable
amount, is for the sole purpose of
-cheapening the paint and wholly for
the benefit Of the manufacture and not
at all for giving better value to the
products furnished to the consumer.
1t Is equity true that there are differ
ences In the various grades of linseed
oil, but on this We need not dwell at
present. The substitution of benzine
for turpentine is for the purpose Of
lowering the cost of production, but
when water and alkali are added to
the paint as a substitute for linseed
OIL there is introduced product which
is without any value whatever, and
recognized as especially detrimental
to the quality of the paint. The water
is placed there for the purpose of
cheapening the paint, and by the adj
dition of an alkali to make it appear
thicker than it really is. and this for
the purpose of decelving the people
into believing tht they are getting
more for their money. The consumer
OF such paints is usually informed that
he should add linseed oil as a thinner
to these paints. And why? Because
without the use of it the product
would not be more than dope"
The substitution of mineral or petro-
leum oil, or of other vegetable oils
like cotton seed oil or corn oil, or of
fish Oil is never for the purpose of i'm
proving the quality of the paint, but
rather to cheaper it. Has not the pub
lie a right to know that these pro-
ducts have been substituted for what
is regarded and classes as standard?
l. maintain that they they have such
a right and that the North Dakota law
is simply a step in the direction Of
giving the public information on these
points.
When we substitute some other con-
stituent for linseed oil, as cotton seed
OIL, water and alkalies, is it not Just
that the purchaser should know of it's
presence? The only liquid which is
used in practically every oil paint as
vehicle or menstruum is linseed oil.
In most cases the linseed oil is used
In the raw state in which case liquid
"driers" are needed in order that the
drying of the linseed oil may be ac-
CELEBRATED. In some cases the linseed
Oil has been boiled" cheated to about
$50 degrees F. during which solid
"driers" are added whereby the dry
Ing OF the linseed oil is also acceler-
ated. The North Dakota statute bars
nothing from use in your paints. Sub
stitute water in your paints, If you
choose, or gasoline, benzine, cotton
seed oil. fish oil or any other constitu-
ent, but be honest Tell the public 0s
its presence.
The following quotation CIV. II.
Borton, American Chemical Journal,
Vol. 12-102) is valuable in this con-
nectiOn:
"The use of the lighter boiling pro-
ducts OF petroleum for the purpose CT
adulterating oil of turpentine is SO
we'll known to persons using these ar
ticles that little comment is necessary
concerning the prevalence of this
adulteration. Refined petroleum Of
the proper color and gravity can be
mixed with turpentine in such pro-
portions as to elude the common
methods OF detection, whereas paints
made from such material is not dura-
BILE, but liable to crack, and peel off
soon after it's application"
Query: Nearly all Japan driers and
many of the mixed paints sold in this
state contain large amounts of petro-
leum products. Should not this ques-
tionable practice be made known 20
the public?
The Pigments.
There is but one white pigment
which has the property of producing
good paint If mixed alone with linseed
oil (either raw, with driers or boiled)
to the consistency proper for paints.
This one pigment is Dutch process
white lead
DR.. Thorp of the Institute of Tech
nology, Boston, Mass, says: White
lead is the most important of all pig
ments Owing to the high price of
white lead it is frequently adulterated
with the products, lead sulphate, lead
carbonate, or calcium carbonate"
Hurst, the English authority, says:
AS a pigment, white lead possesses
all the good qualities desired by paint
ers, viz, good color, body or covering
power and permancy." This distin-
guishes it from all other pigments by
the way in which it mixes with oil by
forming paint which readily flows
from the brush, whereas most pig
ments, as for instance. barytes tend
to work what painters call "slimy" or
"streaky." White lead does not ex-
hibit this property but flows evenly
and freely from the brush.
The Two Bases of Paints.
All OF the authorities are agreed
that white lead or white lead and
zinc oxide are the bases for mixed
paints of the first grade and that the
further addition of other products, in
most cases, is for the purpose of
cheapening and not at all to benefit
the consumer. White lead is the most
expensive of all the pigments employ
ed as a base for white paints. White
lead does not crack This is due 20
the formation of lead soap dead line
olate) by the reaction of linseed oil
upon the lead hydrate contained in the
white lead. This results in the forma-
ton of tough. elastic body. White
lead works admirably in oil, has great
body, mixes perfectly and safely with
the majority of permanent pigments
and imparts drying properties to other
slow-drying pigments.
s. Covering Power.
Using this term as indicating the
power of a paint to obscure the sur
face to which it is applied, the finer
any pigment is the greater the cover
ing power OF paint made from it, pro-
vided the increase in firmness does
not increase the oil-taking power TO
such an extent that the working quail
ity Is impaired. The covering power
of a naint ia also denendent ,,non tho
Opacity of the pigment itself. The
following pigments have opacity to
high degree: White lead, zinc, oxide,
