MAKING LME.SULPHUR CON.
CENTRATE.

II ~ OF relatively IJIe Importance

how dense or heavy a concentrated
solution Is made because Il can he
readily diluted in conformity with the
purpose for which II ia TO he used.
To do this Baume hydrometer Is
used the stem Of which has grad
uated scale. When the hydrome;er
IS introduced into the concentrated
lIme-sulphur il sinks to varying
depths. according to the density of the
liquid. In the experiments conducted
il wa found the Baume hydrometer
should register 33 10 - degrees in the
highly concentrated solution. as later
here described. great variation
in density. from 25 10 81 degrees. of
the ordinary home made product was
recorded in the experiments. where
the usual j0-l0O-50 formula was used.
The amount Of sediment left from the
lime and sulphur varied widely. 35 10
80 per cent.

phur on small Scale.
One Of the home made cooking
plants used in tn experiments con-
sisted Of a - horse power boiler from
which steam was conducted into two
fifty gallon barrels. No coils were
used IN the bottoms Of the barrels.
the steam being emitted through the
op2n end OF straight pipe extend
ing within few inches OF the bot
tom Of the barrel Small patches OF
the 5o-lo0-a0 formula, amounting TO
twenty-five gallons Of the finished
product, were cooked AT time. About
twenty gallons Of water were put into
the barrel the steam was turned on
and the water brought to the boiling
point, The lime was then put in and
after il had begun 10 slake the sulphur
was added. The mixture was stirred
! thoroughly throughout the time II
cooking. which lasted an hour II was
allowed to settl about twelve hours
and then the clear solution was
siphoned Of. The sludge or sediment
was put INTO a cider press and the
clear solution pressed out. using ten
ounce canvas cloth for fltcr In the Sc
experiments commercial ground sui
phur and good grade Of lime We're
used.
The b0-loo-50 formula, meaning so
pounds Of lime, 100 pounds Of sulphur
| and water to make 30 gallons OF the
concentrated solution, has generally
been recommended for the prepara-
ton ~ home boiled concentrated lime
sulphur solution. A good grade of
| fresh limestone. containing not less
than 90 per cent. calcium oxide. is
necessary for the best results. Hy-
drafted lime is sometimes used, but II
| is necessary 10 obtain a good grade
this form of lime. as Il contains a
high percentage of moisture.
Highly Concentrated solstion.
\ highly concentrated solution may
be made by using the lime and sui
phur al the ratio of to ., but with
reduced quantities Of water, The for
mula used in sonic OF the commercial
lime-sulphur manufacturing plants IL
/ so pounds Of fresh stone lime, 1870
pounds of commercial ground sulphur
| and water to make so gallons OF the
| finished product. Solutions prepared
| by this formula should test on an
| average of 3S TO 81 degrees Baume.

volume of insoluble materials.
Commercial ground sulphur may be
purchased in car lots for about 1850
| per 100 pounds. and lime at about 60
cents per barrel. making the cost OF
the highly concentrated solution, esti-
mating labor and fuel at 20 cents,
! about $3.50 per barrel of so gallons,
This does not include wear on outfit
and cost OF containers for storing.
