Description: Initiation is the initial phase of the combustion process of a firework. In this stage, the ignition of the chemical components that make up the device occurs, starting the reaction that will generate light, sound, and visual effects. Initiation is crucial as it determines the success of the pyrotechnic display. During this phase, elements such as fuses, gunpowder, and other compounds are used, which, when ignited, initiate the chain of chemical reactions necessary for the controlled explosion. The quality and design of the initiation are fundamental to ensure that the firework ignites safely and effectively, avoiding failures that could result in accidents. Additionally, initiation must be precise, as an ignition that is too early or too late can affect the sequence of the expected visual and auditory effects. In summary, initiation is an essential component in pyrotechnics, which not only ensures the safety of the display but also contributes to the aesthetic experience of it.
