Block of Redstone

A block of redstone (also known as redstone block) acts as a piston-movable redstone power source which cannot be turned off.

Usage
The block of redstone was introduced to provide a solid block to act as a power source.

A block of redstone acts like a regular block powered by a torch:
 * Attached redstone torches will deactivate.
 * Adjacent redstone dust will be powered with signal strength 15.
 * Correctly-facing adjacent redstone repeaters and redstone comparators will be powered.
 * Adjacent mechanism components will be activated.
 * Adjacent opaque blocks will not be powered.
 * Exception: Redstone dust will configure itself to point towards an adjacent block of redstone, even though it won't configure itself to point towards a block powered by a torch.

A block of redstone provides compact storage for redstone, like other blocks of minerals (block of iron, block of gold, etc.).

A block of redstone is one of three redstone power sources which can be moved by a piston (the others being a minecart on a detector rail, and a cauldron measured by a comparator).

Trivia

 * Even though redstone ore must be mined with iron or diamond pickaxes, blocks of redstone can be mined with any pickaxe.
 * The block of redstone used to have a very similar texture to the block of coal, but the block of coal's texture was later changed.
 * As the block of redstone is not fully opaque, chests can be opened when covered by one. Also, non-solid blocks such as ladders cannot be placed onto its sides.
 * If a redstone torch is placed on a block of redstone, after 1 tick the torch will turn off.
