Glowstone
When broken using anything other than a Silk Touch-enchanted tool, a glowstone block drops 2-4 glowstone dust. A Fortune enchantment increases the chances of higher drops to 4 pieces of glowstone dust per block.

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

Blazes
In the Console Edition, a blaze drops 0-2 glowstone dust upon death. This makes glowstone a renewable resource in the Console Editions despite the lack of glowstone clusters due to small worlds.
