ANTRACITE, because not everything has to be black and white.
The facade bricks (non-perforated) have five sand covered sides and one side with possible oblong groove. The structure looks rugged with fine and irregular grooves in the sandy surface. The baking process takes place in a gas-heated tunnel oven under slightly reduced atmosphere.
The brick has a grey-anthracite base. The colour is obtained by a second firing of the bricks in a low oxygen environment. This process can generate light shadings. The colours shown are a near reflection of reality.
