Excerpt from Ordnance and Gunnery
The niter furnishes the oxygen to burn the charcoal and sul phur. The charcoal furnishes the carbon, and the sulphur gives density to the grain and lowers its point of ignition.
The distinguishing characteristic of charcoal is its color, being brown when prepared at a temperature up to from this to 340 red, and beyond 340 black.
Brown powder contains a larger percentage of niter than black powder, and a smaller percentage of sulphur. A small percentage of some carbohydrate, such as sugar, is also added. Its color is due to the underburnt charcoal.

Paperback. Etat : New. Print on Demand. This book presents the theory of internal, external, and terminal ballistics, collectively known as gunnery, which is the science of propelling projectiles from guns. As the study of gunnery requires a working knowledge of mathematics, the author takes pains to present the science in the simplest, clearest manner possible. The author includes discussions on powder grain pressures and their effect on gun construction, the principles of motion, and the principles of the trajectory of projectiles in air. The author also examines principles of riflings and rifled projectiles, and the effects of wind on the projectile. The information in this book provides both a broad overview and a deep exploration of the subject, and will be an invaluable resource for any student of the science of gunnery and the related topics of gun construction and operation.
