Black Powder Manufacturing, Testing, and Optimizing - PDF - by Ian von Maltitz
Definitely worth having in the book collection, this ebook covers alot of ground. More info than the average Joe will probably ever need to know about BP production. I found the entire book very informative, especially the info on various charcoals.
