Things You'll Need
Instructions
Equip a pickaxe and swing at the ground to start mining. Mine at least eight pieces of cobblestone, one piece of coal and three pieces of iron ore. These are located progressively deeper in the Earth.
Return to the surface and right-click on your workbench. This summons a three by three grid. Fill all but the middle square with cobblestone to create a furnace.
Drop the furnace on the ground and then put a piece of coal in the middle. Light it on fire. Right-click on the furnace and use your three lumps of iron ore. This will produce three iron bars.
Use the workbench again. Place an iron bar to the left of the middle square, to the right of the middle square and immediately beneath the middle square. This creates a bucket.
Equip the bucket and then find a cow. They roam the surface of the game world. Right-click on its udder to get milk.
