Redstone dust is a crafting and brewing ingredient. Redstone dust can be obtained by mining redstone ore with a iron pickaxe or better, trading with priest villagers, or by killing witches. Redstone dust can be placed on the ground to make redstone wire. Redstone can also be crafted into a redstone torch and/or a redstone repeater. These items can be used in more complex traps and redstone circuitry.
