Nether Brick Wall is a decorative block that acts as a fence. It can be used to block a particular area in the game.
In order to make a nether brick wall, you will first need to get the required items. Go to the Nether and take 24 pieces of netherracks.
Then move out of the Nether and make your way to the furnace. Use the nether racks on the furnace to make 24 nether bricks.
Leave the furnace and move to the crafting table. Use the 24 nether bricks on the 3*3 crafting grid to make 6 nether bricks.
Now use these six nether bricks on the crafting grid to make a nether brick wall.
