Dragonfire

Dragonfire is an item that is commonly dropped from dragon mobs in stacks of 7-14, excluding The True Wither Dragon.

Dragonfire is a fuel item for furnaces. It works much better then lava buckets, as Dragonfire can smelt 10,000 items before it is all used up. Dragonfire is the only way to create Black Bedrock items. Dragonfire also can be used as a flint and steel with 10x as many uses.
