Glowstone

Glowstone is a light-emitting block in Minecraft that naturally generates in the Nether, typically found in clusters hanging from ceilings or overhangs. Glowstone has a light level of 15, the highest light level in the game. Players can obtain 2-4 glowstone dust by breaking glowstone with any tool (a pickaxe is the most efficient) or even by hand. A pickaxe enchanted with Silk Touch will drop the glowstone block directly. Glowstone dust is used in potion brewing to enhance effects with reduced duration and to craft glowstone blocks. Glowstone blocks can also be used to craft redstone lamps, which can be controlled with a redstone signal. Besides natural generation in the Nether, players can obtain glowstone or glowstone dust by trading with wandering traders or by killing witches. Glowstone's versatile uses, from being a light source to a redstone component and a potion ingredient, make it an important resource in Minecraft.
