WHITE LEAD.


toned by theBoard of Trade for man
ufacture and for discussion, is tina
of white lead, lead pipe and shee
lead for roofing purposes" etc. A
stated In the circular, "Pure lead i,
now being shipped to California. anC
there manufactured into white aC
and reshlpped to Utah, thus COSTING
the people freight both ways, anC
the labor and profit incident thereto
are entirely lost to u.s." In addition
to these very excellent reasons fol-
the manufacture of white lead at
home is the certainty of obtaining
that article pure, for although pure
lead may be sent from Utah, it by
no means follows that we shall get
unadulterated white lead in return
as commercial article. So long as
there are cheaper substances than
lead which can be used to mix with
IL, there IS a great inducement for
manufacturers to adulterate, so
great is the competition in the trade.
Pure white lead has been made here
IN a small way; it could have been
made upon the large scale, proftably.
as the silver contained in our ordi-
nary lead might have been saved.
AS it was the lead had to be purified
at considerable expense. To manu-
facture white lead as a profitable
article a plant would be necessary.
In the first place a building in
which close vessels could be
placed in stacks; in these yes
sells malt vinegar should be
placed, over which pure lead in
thin sheets should be suspended |
the evaporation of the vinegar
should be promoted by placing
the pots in dung, or moistened saw
dust and dung to generate heat and
carbonic acid; pyroligneous acid or
wood vinegar, could be used for the |
acidifying principle. or, probably |
mOiaSses vinegar could be substl-
tuted. The acid vapors of the vine i
gar attack the lead, and the fumes
of the carbOnic acid gas combine to |
form the carbonate of lead. Thus /
the entire mass of lead is corroded |
so that when passed through rollers
it is reduced to pasty conSistence
Any metallic lead left as a core in
the centre is kept for future use; the
pulpy mass is prepared for the mar
ket. In practice it is too frequently
with sulphate of baryta
heavy SPAR, sometimes Gin Eng
land) chalk is used. Now, the pure |
white lead made as above indicated
has property that makes it more
valuable than any other for spread

with the oil better, dries better,
keeps its color and is more durable.
White lead has been made here that
lOes not spread" well; it was pre-
pared with acids and thrown down |
precipitated) by carbOnic acid gas.
This kind of white lead has been |
old here, and called white lead; and
IS it disappointed the consumer
when Used, it was condemned. The |
French white lead" of commerce is
aTgely used, but it is sold as such at
/ cheaper price. The venetian

With a double dose of "cawk." The s
Best Dutch white lead" is "flake {
White" one part, cawk three parts. :
1he ordinary dutch white" is r
ven more adulterated than this,
Flake white one part, to "caWk" a
heavy SPAR seven parts. All these d
are largely used in the I
rade. There are other brands that q
iced not be mentioned now. One {
hing is certain, if pure white lead is /
made here, and sold to respectable h
.ealers, or steps taken to ensure its +
elivery to the consumer unsOphiS- I
icated, when it reaches foreign I
this industry will become a f
source of revenue. In Q
his connection we should re-estab- h
iSh the raising of linseed oil, as &
by the late President | y
Ieber G. Kimball; the oil prepared | h
y that gentleman was pure, and | n
old to the consumer without adul- 4"

Richard Matthews, of this city, a
made useful paint with salt water r

liquor for making soap. Red lead y
nd other useful pigments were n
made from our lead carbonate ores /
