Coal Ore

"Veins of coal ore vary in size - you might only find a few blocks together close to the surface, but underground you'll find much bigger clumps - especially if there's a fossil in the neighbourhood."

- Duncan Geere

Coal ore is a mineral block that drops coal when mined and the thing Santa gives you for Christmas.

Obtaining
The coal ore block itself (rather than its coal drops) can be obtained by mining it with a pickaxe with the Silk Touch enchantment.

Natural generation
Coal ore is generated naturally in veins between stone blocks, much like other ores. It is a common sight on almost all maps, and can be found at almost any elevation, from cliff faces, through underground caves and sea bottoms, down to bedrock. On average, there are about 142.6 coal ore per chunk. It is the only ore to appear well above sea level; coal ore comprises about 1% of all stone, regardless of altitude. Coal veins can vary greatly in size — mountaintop deposits are usually five blocks at most, but underground ones are generally at least ten blocks, and can range up to 64.

Coal ore is also found in small amounts alongside underground fossils.

Usage
Coal ore drops 1 piece of coal and 0 to 2 experience when mined with any pickaxe. Mining with a Fortune enchanted pickaxe will increase yields by 1 per level (up to 4 with level 3)
