    en.wikipedia.org/wiki/Burst_charge

    Burst charge compositions are usually coated onto rice hulls or other low-density fillers, which increases the rate of combustion. In artillery and Naval artillery the burst charge or bursting charge is ignited by a primer at the base of the shell. [2] This engraving shows a 12-pounder U.S. shrapnel shell c. 1865. It is fitted with a Borman fuze.
