Take two parts of the chlorate of potash, and one of antimony; they must be separately levigated to an impalpable powder, in a marble mortar, and mixed together with an ivory knife; to granulate it, it must be made into a thick paste, with spirits of wine, in which must be dissolved a little gum mastic to make it adhesive; and, by forcing it through a hair sieve, it will be formed into grains. Four parts of potash, and one of antimony, will detonate; but this mixture was found, after a great number of trials by an eminent chemist, not to be sufficiently strong to be depended upon.
