Blue Stained Glass

Blue Stained Glass is a dyed variant of glass that retains transparency while displaying a blue tint. It is crafted by combining glass blocks with blue dye. Like regular glass, blue 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.

Blue 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 blue stained glass panes.
