White Stained Glass is the white variant of stained glass — a dyed glass block crafted by surrounding 1 white dye with 8 glass blocks on a crafting table, producing 8 blocks per craft. White Stained Glass is transparent, emits no light, never catches fire from lava, and stacks to 64. White Stained Glass also generates naturally in the atriums of trial chambers alongside black stained glass. Hardness 0.3 and blast resistance 0.3 leave stained glass fragile: White Stained Glass breaks in about 0.45 seconds with any tool or a bare hand, because stained glass has no assigned tool. Only the Silk Touch enchantment (a tool enchantment that makes delicate blocks drop themselves) recovers a broken block; without Silk Touch, White Stained Glass drops nothing.

Builders choose White Stained Glass for bright window walls, skylights, and greenhouse roofs. Mobs cannot normally spawn on stained glass, and mobs treat stained glass as completely opaque, so monsters cannot see players behind a White Stained Glass window. Six White Stained Glass blocks crafted in two rows of three yield 16 white stained glass panes for thinner window frames. A single White Stained Glass craft costs 8 glass blocks and 1 white dye, so a large curtain-wall project needs a furnace line smelting sand into glass. Stock spare White Stained Glass blocks before building: a block broken without Silk Touch drops nothing, and every misplaced block is lost glass.
