Of course, how do you think I know that archaic method? By reading history books on the early production of gunpowder. From those books I know how to make all sorts of varieties of gunpowder, how to make it explode with horrendously loud noise, how to make it explode in colours, how to magnify the power of explosion, how to quicken the speed of explosion, how to make it resistant to water, etc. Most importantly, I know how to make grainy gunpowder, the most important innovation along with smokeless "powder" and chemical starters that initiate the explosion of the cartridge (the latter two belong to 19th century though).

They used that method with manure in the early stages of the history of gunpowder. In the later stages of gunpowder production, they mined the saltpetre, such as the vast Chilean deposits I mentioned I would exploit if I was to make a Roman voyage to the Americas.
