Brick

Clay bricks are created by smelting clay in a furnace. They can then be crafted into brick blocks when arranged in a 2×2 box on the crafting screen; therefore it is possible to make using the player's inventory's 2x2 crafting square. These blocks are mostly used for aesthetic value, but can be used as a construction block. However, as clay is quite rare, these blocks are rarely used for large constructions. Making bricks is currently the only use for clay.

One clay block will yield enough clay for four Clay Bricks, which in turn is enough for one Brick block. Fuel is of course also needed for smelting the clay.
