[Terrapreta] Commercial charcoal briquettes

[Janice Stettler]

Mr. Trevor asked about commercial brands of charcoal like Kingsford.  These products use coal dust, saw dust and charcoal in their formulation.  While coal is carbon, it is a crystallized form without the necessary porosity.  Saw dust sucks up nitrogen in the course of breaking down.  Neither of these constituents are desirable.
