Redstone Dust

 For advanced redstone circuitry, see Redstone circuits.

Redstone Dust is a crafting and brewing ingredient in Minecraft. Redstone Dust is created when Redstone Ore is destroyed. 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 or Redstone circuits.

Redstone is a unique material in the game. Switches and Redstone Torches can provide electrical-like power to wires or objects.

Trivia

 * The introduction of Redstone was a large step towards interactivity, and brought with it the mechanics of Redstone circuits, making it possible to create circuits linked with buttons, levers, pressure plates and logic gates, which can currently be tied to things like doors, minecart tracks and TNT. It is possible, however, to connect levers, buttons and pressure plates directly to these objects, as Redstone wire is not needed when switches are directly adjacent to objects.
 * Redstone Dust's appearance is shared by Glowstone Dust and, to a lesser extent, Gunpowder and Sugar.
 * Another good use for redstone, as people generally accumulate too much of it while exploring natural dungeons, is to use it as a way to find your way in a cave, so that you do not get lost. By placing redstone dust on the right- hand side of the cave, you can find your way out again by keeping the placed dust on your left.
 * Redstone is also useful for making an obsidian generator. This is a bug that will likely be patched in a later update, but is currently a safe and economical way to get obsidian. By using one bucket of water and one of lava, redstone can be converted into obsidian.
 * In Minecraft 1.0 a single block of redstone not connected to anything looks like a small square (rather than a +).
