Which fuse is described as a black match encased in a loose-fitting sheath?

The term "quick fuse" refers to a specific type of igniting device used in fireworks, which is designed for rapid ignition. A quick fuse is characterized by its speed and reliability in igniting the fireworks quickly, allowing for a prompt and safe start to a display. The black match encased in a loose-fitting sheath is a fundamental design element of this fuse, facilitating the quick transfer of flame to the firework’s charge.

Understanding the quick fuse’s properties is essential in fireworks safety and design, as it ensures that the fireworks ignite in a timely manner, providing both visually stunning effects and maintaining the required safety protocols during a display. This characteristic distinguishes it from other types of fuses, such as electric or lance fuses, which have different construction and functions.
