GRAPHITE 311 



the manufacture of stove polish, of foundry facings, and of 

 pjraphite paint, which is used to protect ironwork (as in smoke- 

 stacks, iron roofs, elevated steel structures, etc.). While 

 crystalline graphite is used to some extent, its special proper- 

 ties are not absolutely required, and hence the amorphous 

 variety, both natural and artificial, is largely employed for 

 these purposes.
