Explosive Compounds. 



The following prescriptions contain most of the 

 substances which have been found to produce ex- 

 plosions. Potassium Chlorate, and in fact all other 

 Chlorates, should never be dispensed with organic, 

 combustible or oxidizable bodies. 



A mixture of Hypophosphite of lime, Chlorate of 

 Potassium, and Lactate of Iron exploded, and nearly 

 killed the perscription clerk who was compounding 

 it. 



Even the simple trituration of Calcium Hypophos- 

 phite is dangerous. Physicans not infrequently 

 order a solution of Chromic acid in glycerin. But 

 when the acid is added quickly and all at once to 

 the glycerin, a readily explosive substance like 

 nitro-glycerin is formed. Chlorate of potassium 

 when mixed with tannin or muriate of morphia, 

 often explodes. The combination of iodine and 

 and preparations of ammonia must be made caut- 

 iously, as iodide of nitrogen is formed, which ex- 

 plodes on the slightest touch. Indeed, one ought 

 to be very careful in ordering and compounding 

 mixtures in which easily reducible substances enter, 

 such as the chlorates, the hypophosphites, the ni- 

 trates, preparations of iodine or ammonia, chromic 

 acid, glycerin, permanganate of potash, etc.
