Description (From Recipaedia)
Brick Walls can be made by combining several bricks together and binding them with mortar. It is a versatile, strong and good-looking building material. Brick Walls that are no longer needed can be recycled into constituent bricks.
Crafting
It requires 4 bricks to craft brick walls. You get 2 walls.

Notes
- Brick walls can also be painted in a variety of colours for decorative effect.
- They are not walls like the stone wall, but a cube block like a clay block. This means that they are not suitable for a fence replacement.
