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. ADD A COOKIE

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.

Bugs

 * It is possible to duplicate firework stars by adding an extra color to multiple firework stars, as seen here: MC-4193.
 * Crafting a firework star with additional blocks or items that do not otherwise have effects (e.g. dirt block, diamond block, nether star, coal, firework rocket) will consume the additional blocks or items without affecting resulting firework star or explosion. However, adding additional gunpowder, a firework star, or paper to the recipe will not craft anything. MC-4191
