Glowstone is a light-emitting block found hanging from ceilings and overhangs in the Nether. It can be used as a crafting material, broken into glowstone dust, and is required to fuel respawn anchors.

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

Glowstone only occurs naturally in the Nether, where it generates in crystalline blobs on the underside of ceilings or overhangs. They can be found in every Nether biome, although they are significantly rarer in soul sand valleys,^[1] because the ceiling of this biome is made of soul sand or soul soil below which glowstone blobs cannot generate. They can still occasionally generate in caves and canyons in this biome,^[2] because the ceiling is made of netherrack.

Glowstone can also generate as a part of hoglin stable bastion remnants.

Journeyman Clerics always sell one glowstone for 4 emeralds, and wandering traders occasionally sell one glowstone for 2 emeralds.

In Bedrock Edition, wandering traders have a chance of 8.5% (increased by 1% per level of Looting) to drop 1 glowstone when killed while showing the item as trade offer, if the player holds an emerald.

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 and shroomlights.

When placing redstone dust 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.

Glowstone, like other pushable blocks, becomes a block of moving piston when moved by a piston; this momentarily stops it from giving off light.^[3]

Glowstone is used to charge respawn anchors.

If a dispenser containing glowstone is facing a respawn anchor, it can automatically charge the respawn anchor when powered.

Glowstone blocks all sunlight, players and mobs suffocate inside it, mobs are able to pathfind to 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,‌^{[Java Edition only]} and it does not transfer a redstone signal. This behavior also occurs in sea lanterns.

Issues relating to "Glowstone" are maintained on the bug tracker. Issues should be reported and viewed there.

• Rarely, glowstone can be found touching the ground if the ceiling it was generated on was extremely low (2–3 blocks of clearance).
• 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 Edition and Minecraft Education only]}
