What term refers to black match encased in a loose fitting sheath for propagating flame rapidly, used in aerial shells and lance ground display pieces?

Explanation:
Quick Match refers to black match encased in a loosely fitting sheath that lets flame travel rapidly along the fuse. This design is ideal for aerial shells and lance ground displays because it delivers ignition quickly and over a length, so multiple effects can be fired in rapid succession rather than with a delayed burn. The loose sheath reduces resistance and allows the hot combustion to propagate along the fuse faster than a tightly wrapped fuse would. In contrast, plain black match without the outer sheath doesn’t propagate as quickly, Visco (safety) fuse burns slowly for timing delays, and a portfire is a lighting aid rather than a fast-propagating fuse.
