Glass Pane

Glass panes are transparent blocks, which can be used as a much more efficient alternative to glass blocks.

Obtaining
Glass panes can only be obtained by mining them using a tool enchanted with Silk Touch, otherwise, they drop nothing.

Natural generation
Glass panes generate naturally as windows in villages, end cities and woodland mansions.

In 1.14, orange stained glass panes generate in savanna village temples. Yellow stained glass panes generate in plains and savanna village temples.

Usage
Glass panes are much more efficient than glass, as they can make windows of 267% the area of glass blocks because only 6 glass blocks are required to make 16 glass panes.

Placement
If placed without anything on the sides, they will appear as a thin vertical • shape, 2x2 pixels in size; but when something is placed on the sides, it will become flat or turn into a or  or  shape depending on the items surrounding it. The collision box is identical to the shape of the pane, allowing both items and players to fit through 2x2 glass pane holes.

Glass panes are never horizontal.

Block data
In Bedrock Edition, stained glass panes use the following data values:

Trivia

 * If two glass panes are placed with one empty space in between, a spider (which is 2 blocks wide) can still fit through.
 * Glass panes are called "thinGlass" in the game's code, but all glass pane texture files within minecraft.jar begin with the prefix "glass_pane" (e.g. "glass_pane_top.png").
