Glowstone Dust

Glowstone Dust is obtained by mining glowstone blocks (only found in the Nether). Glowstone dust no longer requires a pickaxe to obtain.

Uses
When mined properly, each glowstone block yields 2 to 4 glowstone dust that can be reconstituted into a block. A glowstone block, like a jack-o-lantern, is a portable light source brighter than a torch. Glowstone dust can also be used to craft Potion of Instant Healing II and it may be required to craft lanterns in a future update. Unlike Redstone dust, Glowstone dust cannot be placed.

Can be used in potions to increase the strength of its effect, which will however reduce a potion's effect time.

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.

Trivia

 * In the code, Glowstone Dust is referenced as "yellowdust".
 * The icon for Glowstone Dust is a recolored version of the Redstone Dust icon.
