Glowstone

GLOWSTONE

Glowstone is a golden block that glows indefinitely. This block can only be found naturally in The Nether. Breaking this block drops Glowstone dust, which may be used to re-craft the glowstone blocks. Glowstone gives off the same light level as the sun. Unlike torches, it isn't destroyed by water and continues to emit light even when submerged like Jack-O-Lanterns.
