Glowstone Dust

Glowstone Dust is obtained by mining glowstone blocks, which are only found in the Nether (or acquired through trading). Glowstone blocks drop 2–4 pieces of dust. Using a tool with a fortune enchantment will increase the amount of dust dropped, but it will never exceed 4. Glowstone dust can also be dropped by Witches.

In the Xbox 360 Edition, Blazes drop 0–2 Glowstone Dust.

In Pocket Edition, glowstone dust can be obtained by creating and activating the nether reactor, which drops enough dust for around usually 15 glowstone blocks. Glowstone blocks can be crafted with the PE crafting table and does not require the stonecutter.

From blocks of glowstone
When broken using anything other than a Silk Touch-enchanted tool, a block of glowstone will drop 2–4 glowstone dust. A Fortune enchantment increases the chances of higher drops, but even then, the maximum drop is 4 pieces of glowstone dust.

From witches
A witch may drop up to 6 pieces of glowstone dust upon death.

From blazes
In the Xbox 360 Edition, a Blaze drops 0–2 glowstone dust upon death. This makes glowstone a renewable resource in the Xbox 360 Edition despite the lack of glowstone clusters due to small worlds.

As a brewing ingredient
Glowstone dust can also be brewed into most potions to increase the potency of their effect.
