Glass is a transparent solid block that can be dyed into stained glass, or crafted into tinted glass.

Obtaining

Breaking

Glass drops itself only if it is broken with a tool enchanted with Silk Touch. Otherwise, it drops nothing.

Glass does not have an assigned tool; it is mined at the same speed regardless of what tool is used.^[1]

Usage

In Java Edition, glass blocks adjacent to other glass blocks are invisible when viewed through glass that is identical in color.

Mobs cannot spawn on glass blocks.

Glass blocks cannot be seen through by mobs, as they treat them as completely opaque. Mobs may look at players through glass, but this is purely visual.

Redstone dust and components can be placed on glass, but cannot power glass. Glass can't cut vertical redstone. Vertical redstone can be placed on glass. In Java Edition, it transmits redstone signals up, not down. Otherwise, glass in redstone circuits is functionally the same as a top slab.
