Which element of a flintlock system ignites the main charge upon firing?

In a flintlock system, the component responsible for igniting the main charge upon firing is the frizzen. When the trigger is pulled, the hammer falls, bringing the flint down onto the frizzen. This action causes a spark to be generated as the flint strikes the steel surface of the frizzen. The spark ignites the fine powder located in the flash pan, and as this powder ignites, it creates a flash that travels through the touch hole into the main charge of gunpowder located in the barrel, resulting in ignition of the projectile.

The functioning of the flintlock hinges on the interaction between the flint and the frizzen, making the frizzen a critical element in the ignition process. This mechanical design is central to the operation of flintlock firearms and illustrates the importance of each component in successfully discharging the weapon. Understanding the role of the frizzen helps in comprehending the overall operation of the flintlock ignition system.
