Which item is a long tube containing slow burning pyrotechnic composition used to ignite fireworks?

• A. No Fire Current
• B. Portfire
• C. Fusee
• D. Black Match

Answer: (B)

Portfire is a long tube filled with slow-burning pyrotechnic composition that provides a steady, lasting heat to ignite fireworks. This sustained burn allows reliable ignition of fuzes or time fuses, even in less-than-ideal conditions, without the rush of a quick flare. It differs from a fusee, which is a rope-like slow-burning fuse, and from black match, which is a short, fast-burning cord. A no-fire-current item isn’t an ignition device at all. So the long, tube-shaped ignition source described is portfire.
