Gold Nugget

A gold nugget is an item used for brewing potions. Created by smelting gold armour and horse saddle and swords and tools in a furnace, or killing zombie pigmen.

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.

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.
