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 step blocks. It can be placed by players in Creative mode (as of 0.28).

Currently in Minecraft Beta, 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% of all rock, 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.
 * If obtained in the inventory, Coal Ore can not be smelted in a furnace.
 * Coal can come in veins of over 20 or even 30 blocks.
 * Before crafting, stone slabs were dropped from coal ore instead of a lump of coal.
