VII. Yield of Charcoal 



The yield of charcoal is depend upon the form of the kiln, the 

 kind of wood, the amount of moisture in the wood, and the season. 

 It is further influenced by the method adopted ; in case of the " Inside 

 Kiln Extinction Method," it depends upon the choice of the moment for 

 extinction ; and in case of the " Outside Kiln Extinction Method," upon 

 the " Finishing ignition." It is hard, therefore, to obtain any fixed standard 

 with regard to the yield.
