Iron Ore

Iron is a mineral of middling rarity - not too common, but not too rare. Most players prefer using iron tools, since iron is far more common than Diamond and more durable than Stone. It only appears in the bottom half of the map (rows 1-64). It is found in approximately 0.72% of stone from rows 2-61. In Survival Test, it only gave the player a Block of Iron if mined. It was introduced in Classic 0.0.14a. On average, there are 84 iron ores per chunk.

In Indev, Alpha and Beta, iron ore can be smelted in a furnace to make an iron ingot; iron ingots are used to make all the medium quality tools, armor, buckets, Flint and Steel and shears.

In Beta, iron ore requires a stone, iron, or diamond pickaxe to successfully extract. Iron Ore is found commonly in caverns. A player created mine rarely picks up iron ore. Iron Ore is also found near subterranean lava lakes, together with Redstone Ore, Gold Ore, and Diamond Ore.

Iron ore is often used in player traps as it can be mined and replaced in its raw form.

Trivia
*The veins could be as big as 167 ores.
 * Iron ore veins can move diagonally and are sometimes unconnected.
 * Iron in Classic spawns in huge veins, sometimes big enough to protrude into 3 caverns.
 * In an early version of the game, before the furnace was added, Fire was used to smelt iron ore into ingots.
 * In Survival Test, breaking iron ore would cause 1 - 3 iron blocks to drop.
 * In third person view, all ores being held by the player such as Diamond Ore, Gold Ore, or Redstone Ore, seem to look like the texture is reversed, like TNT.
