Coal

Coal is a mineral item mainly obtained from coal ore. It is primarily used for crafting torches and campfires, in addition to being used as fuel.

Coal ore when mined using a pickaxe drops 1 piece of coal. If the pickaxe is enchanted with Fortune, it may drop an extra piece per level of Fortune, up to a maximum of 4 with Fortune III.

When used in a furnace as a fuel, a piece of coal lasts 80 seconds (smelting up to 8 items), like charcoal. Coal used as fuel lasts more than 5 times longer than wood planks or wood logs used as fuel, being more efficient than any other use of wood for smelting in Java Edition, but outlasted by wooden slabs in Bedrock Edition. Though when smelting large amounts of items, converting the coal into a Block of Coal is even more efficient since 1 block of coal is made out of 9 coal but lasts 10 times as long as coal.
