we may conclude that in those solutions in which the formula 50-100-50 

 or 60-125-60 is used, thus insuring an excess of sulfur, that there is but 

 very little advantage to be gained from re-heating the solution before 

 using, 



SUMMARY. 



1. If formula 50-100 50 or 60-125-60 or any other formula providing 

 for an excess of sulfur is to be used, the lower the amount of magnesia 

 in the lime used, the greater the amount of sulfur to go into solution. 



2. If an analysis of the lime used is available an amount of lime 

 should be used so that there shall be twice as much sulfur as calcium 

 oxide. It is only in this way that a maximum amount of sulfur can be 

 made to dissolve. 



3. There is no particular advantage to be gained by filtering the lime 

 sulfur solutions before storing. While there is a slightly greater 

 dropping off in the total sulfur in the unfiltered solution than in the 

 filtered, there is a smaller decrease in the sulfide sulfur in the unfiltered 

 than in the filtered, provided an excess of sulfur has been used in the 

 manufacture of the solution. 



4. In those solutions, in the manufacture of which an excess of sulfur 

 has been used, only a very slight increase in the amount of total sulfur 

 in solution is observed when the solution is re-heated before using. 

 This increase is not sufficient to pay for the cost of such an operation.
