Chapter 2 — Construction of Chrysanthemum Shells

Japanese firework shells are of two principal types, the so-called poka and the warimono (chrysanthemum). The poka breaks just hard enough to disperse its contents into the air. The shell is made only as strong as it needs to be to withstand the shock of being fired. In contrast, the chrysanthemum shell must be strong enough to allow the bursting charge to distribute the stars far from the point of explosion. The quantity of the bursting charge must be great enough to meet this requirement. There are, however, shells having characteristics between those of warimono and poka.
