Nether Brick Fence

Nether Brick Fences were added to the Nether as a part of Nether fortresses. Currently, Nether Brick Fences cannot be set on fire, unlike wooden fences.

Occurrence
Nether Brick Fences are naturally found in Nether fortresses where they form window bars and gate-like structures.

Trivia

 * Nether Brick Fences do not connect to regular fences when placed next to each other. They do, however, connect to fence gates just like regular fences.
 * By alternating between Nether Brick Fences and regular fences, you can create a barrier that players can walk through but many mobs cannot.
 * It is not possible to place pressure plates on top of them as one would with wooden fences.
 * Unlike regular fences 6 Nether Bricks can craft 6 Nether Brick fences while 6 sticks will produce 2 regular fences.
 * Nether Brick Fences do not burn when placed near open flame or lava, like regular fences would.
