Cordite's positive aspects around gunpowder had been minimized maximum strain during the chamber (therefore lighter breeches, and many others.) but longer large force.

The resultant syrup, coupled with drinking water and surfactants, may be heated and agitated inside of a pressurized container right up until the syrup types an emulsion of little spherical globules of the desired dimensions. Ethyl acetate distills off as pressure is bit by bit lowered to depart tiny spheres of nitrocellulose and additives. The spheres is usually subsequently modified by including nitroglycerine to enhance Vitality, flattening concerning rollers to some uniform minimal dimension, coating with phthalate deterrents to sluggish ignition, and/or glazing with graphite to further improve movement features during blending.[7]: 328–330 [29]
