SPECTROSCOPY IN INDUSTRY HARRISON 213 



So we see paper manufacturers wlio want to discover the scource 

 of tiny black specks in their product, bakery equipment manufacturers 

 who wonder if their new coating compound for pans is contaminating 

 the dough, spark plug manufacturers who wish to study the effect 

 of minute amounts of alkali metals in improving sparking, metal- 

 lurgists who wish to trace the origins of ores, all trying spectroscopic 

 methods, and usually finding them helpful. It should be remembered 

 that application of such methods to industry is only beginning, and 

 their full power can only be realized by detailed attention to such 

 problems as are presented for solution.
