When broken without a tool, or with any tool not enchanted with Silk Touch, a glowstone block drops 2-4 glowstone dust, or more with a Fortune tool (but never more than 4).
Glowstone only occurs naturally in the Nether, where it generates in coral-like clusters on the undersides of netherrack.
Villager clerics will sell 1-3 glowstone for an emerald as a third tier trade.
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 and beacons.
In redstone circuits
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.

- Since 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).
- When glowstone is placed 9 or more blocks above ground level (out of its lighting range), the glowstone will actually cast a shadow, despite being a light-emitting block.
