Isn't that a metaphor that someone decided to put in Cromwell's mouth almost two centuries later than the battle of Edgehill took place ?

Causes of gunpowder spoilage...
Joseph Fernandes Pinto Alpoim (1700-1765) warns the reader about two gunpowder enemies, excess moisture and its opposite, extreme dryness. In the first case, if the gunpowder is stored in a humid place, the charcoal absorbs moisture and the saltpeter dissolves, causing the unit to break with sulfur, which gives rise to what he calls a viscous tartar. On the other hand, if the gunpowder is stored for a long time in a very dry place or outdoors, the charcoal will detach from the composition, separating as a fine powder, making the gunpowder less active. He exemplifies how this phenomenon can be verified, which consists of taking gunpowder samples from the top and bottom of a barrel: the first one "weighs less than the bottom", that is, has lower density.
