Glowstone Dust is a crafting material obtained by breaking glowstone blocks in the Nether, killing witches, or bartering with piglins. Mining glowstone without a tool enchanted with Silk Touch drops 2–4 Glowstone Dust, which can be increased using Fortune.

Glowstone Dust is primarily used to craft glowstone blocks, which serve as a bright light source. It is also a key ingredient in brewing potions, enhancing certain effects such as Potions of Strength II and Regeneration II by increasing their potency.

Due to its multiple uses in lighting, brewing, and crafting, Glowstone Dust is a valuable resource for players exploring the Nether and creating powerful potions.
