Nether Brick Fences are a type of fence block found in the game Minecraft. They are crafted from Nether Bricks, which are made by smelting Netherrack in a furnace. These fences have a dark, reddish-brown color and are primarily used for decorative purposes or to create barriers in builds. Unlike regular wooden fences, Nether Brick Fences do not connect to other fence types or gates, giving them a unique appearance. They are also fire-resistant, making them suitable for use in areas with lava or fire hazards. Additionally, they can be used to keep mobs contained while adding an aesthetic touch to structures.
