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

Obtaining

Natural generation

A naturally occurring blob of glowstone in the underside of netherrack.

Glowstone occurs naturally only in the Nether, where it generates in crystalline blobs on the underside of ceilings or overhangs. It can also generate as a part of bastion remnants.

Breaking

See also: Fortune § Discrete random

If glowstone is broken using a tool with Silk Touch, the block drops itself. 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. When a glowstone block is broken with any other tool, it drops 2–4 glowstone dust.

Trading

Journeyman-level Cleric villagers offer to sell one glowstone for four emeralds.‌^{[Java Edition only]}

Wandering traders sell glowstone for two emeralds.

Usage

Analyzing glowstone in a material reducer, it turns out to be a 1:1:1:1:1 mixture of Argon, Neon and Krypton noble gases, Boron and an unknown Element.‌^{[Bedrock and Education editions only]}

Light source

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

Redstone circuits

			A
			B

A glowstone block can transmit power up, but not down. Lamp A is powered because the redstone signal travels up the glowstone block. Lamp B is 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, does 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.

Crafting ingredient

Redstone Lamp	Redstone Dust + Glowstone
Respawn Anchor	Crying Obsidian + Glowstone

Note blocks

Glowstone can be placed under note blocks to produce pling sounds.

Respawn anchors

Glowstone is used to charge and make respawn anchors.

Transparent block

Glowstone blocks all sunlight, players and mobs suffocate inside it, and it blocks a Beacon beam, preventing the Beacon's activation. However, like transparent blocks, it does not prevent the opening of chests, monsters (including Slimes) cannot spawn on it, and it does not transfer a redstone signal. This behavior also occurs in Sea Lanterns.

Trivia

• Because glowstone blocks become block entities when moved by pistons, this momentarily stops them from giving off light.
• Rarely, glowstone can be found touching the ground if the ceiling it was generated on was extremely low (2–3 blocks of clearance).
• Glowstone, although transparent, causes the sky light to count down as if it hit a non-transparent block, while still letting through this light.
