Instructions
Mine within the elevation range 0 to 67 with a stone, iron or diamond pickaxe to successfully extract iron ore, which is iron in its raw material form. Iron ore blocks are grey with tan colored veins of ore.
Smelt the iron ore in a furnace to create the iron ingot, which is the form of iron from which most practical items are crafted. To do so, right click on your furnace block and mix coal with iron ore. Iron ingots also can sometimes be found in dungeon chests.
Place nine iron ingots on a crafting bench to craft the iron block. Other items that can be crafted using iron ingots include swords, armor, tools, doors, compasses and flint and steel.
