Including a little potassium chlorate (KCl, O3) to a mercuric priming substance distributed warm particles much more extensively with a smokeless powder charge. Potassium chlorate is an oxidizing substance, instead of a main explosive. It leaves a salt deposit, potassium chloride (KCl), along with the mercuric salts that is hygroscopicwater holdingand hence advertises quick deterioration of barrels unless extensively cleaned up quickly after shooting.

Due to the fact that of a lack of dependability, the military continued making use of mercurial-potassium chlorate guides throughout World Battle II as well as beyond.
