A potentially ambiguous name that could refer to either an electrical fuse (a sacrificial device to prevent excessive current in a circuit) and a [[explosive|explosives]] fuse.  For tagging purposes this tag refers specifically to the explosive variety of fuse, used to initiate the ignition of explosives and [[fireworks|pyrotechnics]].  In particular this tag especially refers to the burning variety of fuse you would find on consumer fireworks or the stereotypical black spherical old style bomb.  Given their visual similarity, they're occasionally referred to as a "wick" (such as those those used in candles and oil lamps).
