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.

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.
