Coal

Coal is a common mineral obtained by mining coal ore or looting chests in mineshafts, villages, and bastions. It is primarily used as a fuel source and a crafting ingredient for various items.

Coal is the most efficient early-game fuel, capable of smelting eight items per piece in a furnace, smoker, or blast furnace. It can also be crafted into torches, campfires, and soul torches, making it essential for lighting and exploration.

Coal can be traded with novice-level armorer, toolsmith, and weaponsmith villagers for emeralds, providing an easy way to obtain valuable resources. Due to its abundance and versatility in fuel, lighting, and trading, coal is one of the most useful resources in Minecraft.
