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

Obtaining[edit]

Firework stars are only obtainable through crafting, but can also be found in the creative inventory.

Ingredients	Crafting recipe	Description
Gunpowder + Matching Dye + Extra ingredients (optional)		Up to eight dyes can be added. Up to one of any head, a gold nugget, a feather, or a fire charge can be added. Both the diamond and the glowstone dust can be added with any of the other ingredients.
Matching Firework Star + Any Dye		Adds a "fade to color" effect to the firework star, overwriting any existing fades. Up to eight dyes can be added.

The only usage of firework stars is to create fireworks.
