What is ignition tube used for?

An ignition tube is typically used in pyrotechnics and fireworks to initiate combustion. It serves as a conduit for a flame or spark to travel from a fuse or igniter to the explosive material, ensuring a safe and controlled ignition process. The tube helps protect the igniter from environmental factors and allows for a delayed ignition if necessary. Overall, it plays a crucial role in the reliable ignition of fireworks and similar devices.
