Firework compositions and parts

Compositions which are used for fireworks are mixtures of various components and all the oxidizers dissolve in water. These compositions therefore are easily damaged by moisture. Sometimes this is useful for temporarily keeping a composition in a safe state, as in the wet process for example,sometimes however this can lead to a misfire. 

So many kinds of composition are used for fireworks that a particular kind of operation may be required for each type. This is quite complicated and troublesome, but important.
