1. In a method of preparing an explosive composition by combining inorganic nitrate particles with a water-in-oil emulsion comprising (a) a liquid carbonaceous fuel having components which form a continuous emulsion phase, (b) an aqueous solution of an inorganic oxidizing salt forming a discontinuous emulsion phase dispersed at discrete droplets within said continuous phase, and (c) an emulsifying agent to form a blend of said particles and said emulsion containing a sensitizing amount of dispersed gas bubbles or voids, the improvement comprising forming said inorganic nitrate particles and the components of said emulsion into a structure that minimizes the loss of water from said droplets and transportation thereof across said continuous oil phase to said nitrate particles.
