Coal Ore

Coal Ore is a mineral that is a common sight on almost all maps. It is found at almost any elevation, inside caverns, cliff faces, and underground. A lump of coal can be mined directly from Coal ore using a wooden pickaxe or better. Coal lumps can be combined with sticks to make torches, or used as fuel in a furnace or Minecart. When burned in a furnace, it provides 8 uses for each coal lump.

In Survival test, it gave the player 1 to 4 stone slabs. It can be placed by players in Creative mode (as of 0.28).

Currently in Minecraft, mining coal yields one lump of coal. Coal blocks are very common to find and are the only ore to appear well above sea level; coal ore comprises about 1.25% of all stone, regardless of altitude. Common deposits can vary greatly in size - mountaintop deposits are typically limited to five at most, but underground ones can be anywhere between ten and fifty without being noted as unusually large.

Trivia

 * In an early version of the game, when destroyed without any items coal ore drops a single coal, and three when mined with a pickaxe.
 * Coal ore can be obtained via silk touch and when smelted it gives coal.
 * Coal can come in veins of over 20 or even over 30 blocks.
 * The Fortune enchantment applies to coal ore blocks, i.e. mining coal with it may yield more than one lump per block.
