Brown Stained Glass is a dyed variant of glass that retains transparency while displaying a brown tint. It is crafted by combining glass blocks with brown dye. Like regular glass, brown stained glass must be broken with a Silk Touch-enchanted tool to drop itself; otherwise, it shatters. Mobs cannot spawn on it, and they perceive it as opaque, even though players can see through it.
Brown stained glass can be used to modify the color of beacon beams by averaging its RGB color values with other stained glass blocks stacked above the beacon. Additionally, it serves as a crafting ingredient for brown stained glass panes.
