Iron Ore

Iron ore is a mineral block found underground. It is the most common mineral that can be used to make tools and armor.

Obtaining
Iron ore will drop as an item if mined by a stone pickaxe or better. If mined by any other tool, it will drop nothing.

Natural generation
Iron occurs only around from bedrock to slightly above sea level (layers 1-63). However, almost all of the iron ore will be at the lower levels. On average, there are about 77 iron ores per chunk.

Veins can vary in size, but the most common is 2×2×2. Iron always comes in veins of 4 to 10 unless dirt, gravel, a cave, or another ore overlapped into it. Each block in the vein, which otherwise would be stone, has a random chance of being iron ore instead.

Trivia

 * There's no particular beige iron ore in real life. Colors of common real life iron minerals range from black or red to gold-yellow but none of them are truly beige.
