Glass Pane

Glass Panes are transparent blocks which can be used as an alternative to Glass blocks. They connect to adjacent panes, much like Redstone, Iron Bars, and Fences. They have the same texture as Glass. Glass panes are used for the windows of Villages. When placed without anything on the sides of it it will appear in the shape of a ┼ but when something is placed on the sides of it it will become flat or into an ┌ shape or a ┬ shape depending on the items surrounding it.

Uses
Glass panes are much more efficient than glass, as they can make windows of 266% more area than Glass blocks, because only 6 glass blocks are required to make 16 glass panes. They appear somewhat brighter than glass blocks.

Because of their shape they can be used to displace water and lava to make an air pocket.

Also, items can fit through but not the player, so it can be used to prevent the player from falling in a lava trash disposal.

If used on the edge of a building as windows with no block above it the player can look quite far up to the sky.

Crafting
Glass Panes can be crafted by placing 6 Glass blocks in a 2x3 horizontal rectangle.

Bugs

 * Before Beta 1.9 Pre-release 4, Glass Panes would not attach to many transparent blocks, mainly stone slabs, stairs, pistons, sticky pistons, Farmland, Iron Bars, Doors, Signs, and Fences.

History
Glass panes were introduced in Beta 1.8. Before Beta 1.9 Prerelease 2, glass panes were dropped as a resource when destroyed.

Trivia

 * A 2x2 area made of glass panes can make a hole big enough for the player to fit through in the middle, but not rain, water, etc. this can be used as an easy entrance for an underwater house, but not an exit. Iron Bars work in the same manner.
 * Be careful where you plant Saplings: when a tree grows, any Glass Panes that are in the way will be removed.
 * Glass Panes are much brighter than Glass Blocks, thus making them more suitable than Glass Blocks for high-visibility structures.
 * 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 do not drop as a resource even using a Silk Touch enchanted pickaxe, unlike Glass blocks.
 * In the minecraft source code, glass panes are called 'thin glass' as seen here (remove spaces): htt p://img ur.com/VI dVV
