Redstone is an element that is used as an ingredient for most mechanical creations in Minecraft, and it is required in some way to get most mechanisms to operate.

may be dropped when a block of Redstone Ore is destroyed with an iron or diamondpickaxe It is also dropped by Witches, (which is why it is renewable) and occurs in block form in Jungle Temples and Woodland Mansions. It also appears in Dungeon, Woodland Mansion, and StrongholdChests, and in Abandoned MineshaftChest Minecarts. This dust can be placed on the ground to make redstone wire. Redstone can also be crafted into: a Redstone Torch, although a redstone torch is not as efficient as a regular torch as it does not give off as much light; a Block of Redstone (as of update 1.5); and/or a Redstone Repeater. Redstone also can be used in traps or mechanisms involving redstone circuits. When redstone interacts with any liquid, it will be destroyed. Redstone can only be placed on solid blocks, excluding Glowstone and top placed Slabs of any kind. When redstone gets ignited, it will last 15 blocks before going to its off state. This can be prevented by placing a repeater and continuing the redstone circuit however will make the output 1–4 ticks longer. A Redstone Comparator (see page for details) creates an instant redstone signal when placed in a line (all facing the same way) unlike repeaters (listed above). The toggle switch must be off in order for this to happen.
