This article is about redstone and redstone dust. For other topics related to redstone, see Redstone (disambiguation).

Redstone is a flat transparent block which can transmit redstone power.

Obtaining

Redstone can be obtained by mining or smelting redstone ore, destroying jungle temple traps, crafting blocks of redstone, killing witches, trading with villagers, or by breaking previously-placed redstone dust. It can also be found in chests that spawn in naturally generated structures.

Breaking

Redstone dust can be broken instantly using any tool, or without a tool, and drops itself as an item. Its hitbox may only cover part of the surface below, depending on the orientation of the redstone.

Redstone dust will also be removed and drop redstone as an item:

• if its attachment block is moved, removed, or destroyed
• if water flows into its space
• if a piston tries to push it or moves a block into its space

If lava flows into redstone dust's space, the redstone dust will be destroyed without dropping redstone as an item.

Crafting

Redstone can be crafted from blocks of redstone.

Ingredients	Crafting recipe
Block of Redstone	9

Drops

A single witch will drop 0 to 6 redstone when they die, even when not killed by the player. The drop chance can be increased to 0–15 using the Looting enchantment.

Mining

A single redstone ore will yield 4–5 redstone when mined with an iron or diamond pickaxe. With the Fortune enchantment, additional redstone up to the enchantment level may be dropped (e.g. 0–3 extra will be dropped with Fortune III).

Natural generation

15 lengths of redstone dust are naturally generated as part of the trap in each jungle temple. 5 lengths of redstone dust can be found in one type of jail cell room in a woodland mansion.

Redstone dust can be found in 44.8% of village temple chests, 26.6% of dungeon chests, and 26.6% of woodland mansion chests, all in stacks of 1–4; and in 12.1% of stronghold altar chests, 18.6% of stronghold storeroom chests, and 16.9% of chest minecarts in Mineshafts, all in stacks of 4–9.

In Bedrock Edition they can be found in 11.8% of stronghold altar chests and 15.2% of stronghold storeroom chests in stacks of 4–9.

Smelting

Trading

Clerics can offer to trade 1 to 4 redstone for an emerald as one of their second-tier trades.

Usage

Redstone is used for brewing, crafting, and in redstone circuits by placing it on the ground to create redstone dust.

Redstone component

When placed in the Minecraft world, redstone becomes a block of "redstone dust", which can transmit redstone power.

Placement

Examples of redstone dust configuration. Top Left: Redstone dust will connect diagonally vertically through non-opaque blocks. Top Right: Redstone dust will not connect diagonally vertically through opaque blocks. Center: Redstone dust gets darker as its power level drops, to a maximum of 15 blocks from a power source.

Redstone dust can only be placed on opaque blocks as well as glowstone, upside-down slabs and upside-down stairs, and hoppers.

Redstone dust will configure itself to point towards adjacent redstone power components and transmission component connection points. Redstone dust will also configure itself to point towards adjacent redstone dust one block higher or lower – unless there is a solid opaque block above the lower redstone dust, or if the higher redstone dust is on a transparent block such as glowstone, an upside-down slab or stair, or a hopper.

If there is only one such adjacent redstone component, redstone dust will configure itself into a line pointing both at the neighbor and away from it. If there are two or more such adjacent redstone components, redstone dust will point at them, forming a line, an "elbow", a "T", or a cross. If there are no such adjacent redstone components, redstone dust will configure itself into a directionless "dot", which can provide power in all four directions.

Redstone dust will not automatically configure itself to point towards adjacent blocks or mechanism components. If such a configuration is desired, the other neighbors of the redstone dust must be arranged to create it.

When redstone dust is reconfigured after placement, it will not update other redstone components around it of the change unless that reconfiguration also includes a change in power level or another component provides an update. This can create situations where a mechanism component remains activated when it shouldn't, or vice versa, until it receives an update from something else – a "feature" of redstone dust that can be exploited to create a kind of block update detector.

Behavior

Redstone dust can transmit power, which can be used to operate mechanism components (doors, pistons, redstone lamps, etc.).

For different reasons, each signal can go up but not back down.

Redstone dust can be "powered" by a number of methods:

• from an adjacent power component or a strongly-powered block
• from the output of a redstone repeater or redstone comparator
• from adjacent redstone dust. The powering dust can be a level higher or lower, but with restrictions:
  • Redstone can be powered by redstone which is one level lower, or on an opaque block one level higher. A transparent block cannot pass power downward.
  • The block "between" the two dust blocks must be air or transparent. A solid block there "cuts" the connection between the higher and lower dust.

The "power level" of redstone dust can vary from 0 to 15. Most power components power-up adjacent redstone dust to power level 15, but a few (daylight sensors, trapped chests, and weighted pressure plates) may create a lower power level. Redstone repeaters output power level 15 (when turned on), but redstone comparators may output a lower power level.

Redstone dust can transmit power up to 15 blocks.

Power level drops by 1 for every block of redstone dust it crosses. Thus, redstone dust can transmit power for no more than 15 blocks. To go further, the power level must be re-strengthened – typically with a redstone repeater.

Powered redstone dust on top of, or pointing at, an opaque block will "weakly"-power the block. A weakly-powered block will not power other adjacent redstone dust, but will still power redstone repeaters and comparators and activate adjacent mechanism components. Transparent blocks cannot be powered.

When redstone dust is unpowered, it will appear dark red. When powered, it will turn bright red at power level 15, fading to darker shades the lower the power gets. Powered redstone dust also produces "reddust" particles of the same color.

Data values

Redstone dust is defined by its ID and block data. Redstone dust also has a block state which is expected to replace the functionality of block data in a future version.
