31 degrees, of the ordinary homemade product was re¬ 
corded in the experiments, where the usual 50-100-50 
formula was used. The amount of sediment left from 
the lime and sulphur varied widely, 35 to 50 per cent. 
Making Concentrated Lime Sulphur on Small Scale 
One of the homemade cooking plants used in the ex¬ 
periments consisted of a 12-horsepower boiler from 
which steam was conducted into two 50-gallon barrels. 
No coils were used in the bottoms of the barrels, the 
steam being emitted through the open end of a straight 
pipe extending within a few inches of the bottom of the 
barrel. Small hatches of the 50-100-50 formula, amount¬ 
ing to 25 gallons of the finished product, were cooked at 
a time. About 20 gallons of water were put into the 
barrel, the steam turned on. and the water brought to the 
boiling point. The lime was then put in and after it had 
begun to slake the sulphur was added. The mixture was 
stirred thoroughly throughout the time of cooking which 
lasted an hour. It was allowed to settle about 12 hours 
and then the clear solution was siphoned off. The sludge 
or sediment was put in to a cider press and the clear solu¬ 
tion pressed out, using 10-ounce canvas cloth for filter. 
In these experiments commercial ground sulphur and a 
good grade of lime was used. 
The 50-100-50 formula, meaning 50 pounds of lime, 
100 pounds of sulphur and water to make 50 gallons of 
the concentrated solution, has generally been recom¬ 
mended for the preparation of home-boiled concentrated 
lime-sulphur solution. A good grade of fresh limestone, 
containing not less than 90 per cent, calcium oxid, is 
necessary for the best results. Hydrated lime is some¬ 
times used but it is necessary to obtain a good grade and 
at least 20 per cent, more of this form of lime, as it con¬ 
tains a high percentage of moisture. 
Highly Concentrated Solution 
A highly concentrated solution may be made, continues 
the bulletin, by using the lime and sulphur at the ratio of 
1 to 2, but with reduced quantities of water. The for¬ 
mula used in some of the commercial lime-sulphur man¬ 
ufacturing plants is 80 pounds of fresh stone-lime, 160 
pounds of commercial ground sulphur, and water to 
make 50 gallons of the finished product. Solutions pre¬ 
pared by this formula should test on an average 33 to 34 
degrees Baume, as explained above, and there is about 
50 per cent, in volume of sludge after allowing the solu¬ 
tion to settle for 24 hours. There is only about 5 per cent, 
to 10 per cent, in volume of insoluble materials. 
Commercial ground sulphur may be purchased in car 
lots for about $1.50 per 100 pounds, and lime at about 60 
cents per barrel, making the cost of the highly concen¬ 
trated solution, estimating labor and fuel at 70 cents, 
about $3.30 per barrel of 50 gallons. This does not in¬ 
clude wear on outfit and cost of containers for storing. 
At the prices of the ingredients mentioned above, the 
high test concentrate would cost about 98 cents more 
per barrel than the low test concentrate made by the 
50-100-50 formula.
