Firework Star

Firework stars are items used to determine the color, effect and shape of firework rockets.

Crafting
The Firework Star can have three attributes - colors, effects and shape: It must have a combination of color, from a single color up to 8 colors when crafted with dyes, and can have any combination of effects, but only one shape. It can also have fade colors; these can be applied by crafting a finished Firework Star with dyes. Adding dyes to a newly created firework star will produce a "Fade to color" effect.

You can also use multiple ingredients on one recipe.

As a crafting ingredient
Multiple Firework Stars can be used when crafting a Firework Rocket, in which case each one will go off simultaneously when the rocket detonates.
