Match quickmatch

Whilst it is apparent that the gunpowder substitute has been developed for use in munitions, it remains to be seen whether the material can be used to the same extent in hreworks. Obvious applications would be as replacements for quickmatch and piped match, both of which are notoriously prone to dampness during wet or humid conditions. 

The gunpowder explodes in a further fraction of a second, the explosion blowing the shell out of the mortar tube in the manner of a shot from a cannon. At the same time a return section of piped match is lit by the explosion, transferring flame back to the top compartment where it reaches the quickmatch placed across the head of the 25 mm pressed delay fuse.

Plastic fuse is routinely used as a fuse extension to quickmatch or piped match, especially when firing rockets, mines or shells. In the latter case, the piped match fuses from a crate of, say, ten shells connected via a single length of plastic fuse which will burn progressively to ignite each of the ten shells in turn. 

PIPED MATCH A fuse Consisting of quickmatch enclosed in a paper pipe that serves to increase the burning speed. 

Quickmatch becomes a nearly instantaneous transfer line if enclosed in a narrow paper tube and is thus used under the name of Piped Match in fireworks for simultaneous initiation of several items (Ref 57, p 191)... 

Type 98 No 7 Mk 6 Model 1 Bomb contd four Thermite-filled electron fire pots. A central channel filled with quick match ran thru the length of the bomb. A BkPdr chge was located in the circular recess of the nose piece (pp 71—72) Type 98 No 7 Mk Model 2 Bomb contd a central Thermite core surrounded by a solidified kerosene, petrol, alcohol, soap mixture. A BkPdr burster chge was located in the nose. A copper tube contg quickmatch was located inside Thermite tube (pp 73—4) ... 

Transfer lines between prime ignition and first fire must be regarded as a part of the secondary ignition system. Quickmatch, a type of black powder fuse that has a more-or-less well-defined burning time and thus acts as a delaying element, will be described in the next chapter. It becomes a nearly-instantaneous transfer line if enclosed in a narrow paper tube and is thus used as piped match in fireworks for simultaneous initiation of several effects. ...
