Redstone Dust is a vanilla crafting and brewing ingredient. Redstone Dust is created when Redstone Ore is mined using an Iron Pickaxe or better. Redstone Dust can be placed on the ground to create a Redstone Wire. Redstone can also be crafted into a Redstone Torch or a Redstone Repeater. These items can be used in more complex Traps or Redstone circuits. In Tekkit, Redstone is a very critical part of crafting; it is used to craft many BuildCraft items.
