What term describes a series of two or more aerial shells or other firework items fired in sequence from a single ignition?

The term that describes a series of two or more aerial shells or other firework items fired in sequence from a single ignition is "Chain Fusing." Chain fusing is a technique used in fireworks displays to create a more dramatic effect, as it allows for multiple devices to be ignited one after the other, providing a continuous display without the need for additional ignitions. This method enhances safety and efficiency during the show, as it minimizes the time spent lighting individual devices.

In contrast, a finale refers to the concluding set of fireworks aimed at creating a spectacular end to the display but does not specifically describe the method of ignition. A lance is a type of firework that consists of a stick with a burning fuse, typically used for special effects, and is not related to the sequential firing of aerial shells. A lift charge is a component of an aerial shell that propels it into the air, but it does not denote a sequence of firings. Consequently, the term "Chain Fusing" accurately encapsulates the process of igniting multiple fireworks in succession from one ignition point.
