glowstone

Duncan Geere Mojang avatar.png Glowstone was added to Minecraft on 30 October 2010 in the Halloween Update - which also added Jack o’Lanterns, clocks and fishing. It occurs naturally in the Nether, generating on the underside of netherack, but if you’re having trouble finding it then clerics in Minecraft villages will sometimes sell small amounts in exchange for emeralds.

Glowstone is a light-emitting block that appears in the Nether.

Obtaining[edit]

Unless broken with a tool that is enchanted with Silk Touch or Fortune, a glowstone block drops 2–4 glowstone dust. If tool with Silk Touch is used, the block drops itself, and if a tool with Fortune is used, it has a higher chance of dropping a large amount of glowstone dust—but never more than 4.

Natural generation[edit]

A naturally occurring vein of glowstone in the Nether.

Glowstone only occurs naturally in the Nether, where it generates in coral-like clusters on the undersides of netherrack.

Glowstone Dust

Trading[edit]

Villager clerics will sell 1-3 glowstone for an emerald as a third tier trade.

Usage[edit]

Light source[edit]

Glowstone blocks emit a light level of 15, the brightest possible light level in the game. They emit the same amount of light as sea lanterns, jack o'lanterns, redstone lamps, conduits and beacons.

In redstone circuits[edit]

A
B
A glowstone block can transmit power up, but not down. Lamp A will be powered because the redstone signal travels up the glowstone block. Lamp B will be off as the signal would have to go down the glowstone, which is not possible.

When placing redstone on a glowstone block, being a transparent block, signals can pass from one block to another diagonally. Redstone wire, even though it may appear to connect up the side of a glowstone block and to the wire portion on top, will not send a redstone signal down the glowstone block. This makes glowstone effective for vertical diodes, logic gate designs and space-efficient instant vertical redstone.

Note that upside-down slabs can be used for the same purpose, and are easier to obtain.

Trivia[edit]

  • Since glowstone blocks become block entities when moved by pistons, this momentarily stops them from giving off light. This will not be fixed.[2]
  • Rarely, glowstone can be found touching the ground if the ceiling it was generated on was extremely low (2-3 blocks of clearance).
  • Glowstone, though being transparent, causes the sky light to count down as if it hit a non-transparent block, whilst still letting through this light.
