A fuse (or fuze) is the part of a pyrotechnic device which initiates the said pyrotechnic device, either thermal, electric or other chemical reaction.
Fuses are different from detonators.
Contents
Types
Burning fuses
Consist of a wick, embedded with a flammable material, such as flash powder. Nitrocellulose wicks are sometimes used.
Black match
Black matches consist of a crude form or burning fuse, it is made by soaking cotton string/sheets in a slurry of black powder.
Safety fuse
Safety fuses consist of a "tube" of gunpowder surrounded by a waterproofed varnished jute "rope". Burn rate is around 1 cm/s.
Electric match
Electric matches use a bridgewire consisting of a heating element to ignite a pyrogen, which in turn ignites the pyrotechnic material.
Other
Sparklers can be used as crude fuses.
Availability
Fuses are found in many types of fireworks, though most tend to be pretty short.
Since 2015, using fuses in US requires an ATF license.[1]
DIY fuse
A simple fuse can be made by adding gunpowder (black powder or smokeless powder) along a sheet of wet wrapping paper/cotton then twist it.[2] Other liquids can be used.
Safety
Fuses can ignite relative easy and should be kept away from flammable things.
