Gold Nugget

A gold nugget is an item used to make gold ingots, golden carrots, and glistering melon slices.

Zombie pigmen
Zombie pigmen, when killed, may drop 0-1 gold nuggets. When killed using a weapon enchanted with Looting, they may drop an additional gold nugget per level of looting used, up to a maximum of 4.

Mining
Nether gold ore mined using a pickaxe drops 2-6 gold nuggets. If the pickaxe is enchanted with Fortune, it may drop an extra unit per level of Fortune, up to a maximum of 24 with Fortune III.

Usage
Gold nuggets can be used to craft a golden carrot or glistering melon for brewing. Also, gold nuggets can be combined with gunpowder and dye to create a firework star that bursts in a star-shaped explosion.
