Glowstone Dust

Glowstone Dust is obtained by mining glowstone blocks (only found in the Nether) with a pickaxe.

Uses
When mined properly, each glowstone block yields 2 - 4 glowstone dust that can be reconstituted into a block. A glowstone block, like a jack-o-lantern, is one of the only portable light sources brighter than a torch. Glowstone dust has no other crafting uses, but it may be required to craft lanterns in a future update.

History
Glowstone dust was introduced in Alpha as part of the Nether environment in the Halloween 2010 update. In Beta 1.6.6, the crafting recipe for glowstone blocks was changed from 9 units of glowstone dust to 4.
