Abstract

Abstract A device is provided which carries a solid particulate primary component for a liquid-solid explosive which includes a container having an opening for receiving the liquid component and which carries a sensitized particulate material such as an oxidizing material as the solid primary component adjacent a cap well on the container, and a chamber for carrying a secondary charge or liquid-solid explosive charge component such as a particulate oxidizing material as a solid particulate secondary component, the primary component and the chamber being separated in the container by a porous member which will pass the liquid component but neither of the solid components. A cap sensitive explosive composition is formed, for example, by pouring a liquid component through the opening of the container and into the chamber and allowing it to admix with both the solid primary component and the solid secondary component.
