What distinguishes quick match from black match?

Quick match is distinguished from black match primarily by its construction and the way it is designed to function. Quick match is encased in loose-fitting paper, allowing for faster ignition and combustion. This design facilitates a more rapid burn and ensures that the igniting material has a clear path to ignite quickly.

The loose-fitting paper allows for air to reach the pyrotechnic material inside, promoting a quicker and more consistent burn rate that is essential for synchronization in fireworks displays and special effects operations. This property makes quick match particularly suitable for connecting to other pyrotechnic devices that require immediate ignition.

In contrast, while black match is also a type of fuse made from black powder, it does not typically have the same loose-fitting casing, resulting in a slower ignition speed compared to quick match. The other options do not accurately capture the unique characteristics of quick match as compared to black match.
