As the burning of black powder is usually a surface phenomenon, a fantastic granulation burns quicker than a coarse one. A fast burning rate is effective ballistically but tends to develop abnormal pressures in the gun barrel. Consequently, black powder in its powdered type burned too rapidly being a secure propellant in firearms. To solution this, Europeans inside the 15th and sixteenth hundreds of years began production powder in significant grains of uniform size. The speed of burning may be diverse through the use of a unique measurement of granule.

An case in point is cited in which 34 lbs of serpentine was needed to shoot a 47-pound ball, but only eighteen lbs of corned powder.[36] The optimum dimensions on the grain depended on its use; larger sized for big cannon, finer for smaller arms. Much larger cast cannons ended up very easily muzzle-loaded with corned powder employing a extended-dealt with ladle.
